Garage Star Delrin Differential Bushings!

****UPDATE: Use coupon code "diffbushings2016" at www.garagestar.com to get a discount on these bushings!****
*****UPDATE #2: At 3:40 where I smack out the upper inserts, that is NOT the proper way to do it (just finding this out). There is a sleeve on the front most diff bolt that just needs to slide down a little bit in order for the diff to come free. Sorry guys, that's why I try to remind you that I'm not a professional!!!
What's up y'all? I've been wanting to do this upgrade for a while so I finally got around to it. I will be installing a set of motor mounts in the near future as well! Thanks for your patience over the last couple weeks, I had a couple issues with B&B over the weekend so I couldn't complete any episodes of that. Anyways, hope you enjoy!
Bushings!

Love how your videos from 5 years ago are helping me with just about everything on my Miata in 2021.

[@FriedBacon88]

This was better than the engine mount video which had stilted cuts from one step to the other without showing your work/how to do it. This was very helpful!

[@NickNardone]

Dude this is seriously the most helpful KZbin channel I’ve ever experienced

[@codwizard7526]

Yup by far

[@dennistolbert4469]

put the bushings in the freezer, to shrink them and they will almost just push in buy hand

[@pr0xZen]

Ehy, warning! Every time you drain fluid from something with a separate (bottom) drainplug and "fill plug" (differential, gearbox etc)- ALWAYS make sure you loosen up the fill port - BEFORE the drain port! If you open the drain at the bottom, drain all the fluid, and /then/ find out you can't get the fill plug loose/out - you're in for a very bad day.

[@jamesflores9456]

what id do is put a ball valve on the bottom and get the gear oil on top of the diff so gravity fills it i measure the oil put a little extra fill it than close the valve

[@jmpcrx]

Could always tip the car upside down...

[@Gettinbentoffroad]

Well for example for the trans you could always fill through the gear shifter, as for the diff you could fill it through the pumpkin by the drive shaft always around the plug

[@tangles01]

So draining the diff... not needed for this job, but since you're playing with it change your diff oil while your there?

[@natemorris535]

your channel's gonna blow up soon, I can see it

[@aaweewaa389]

+Nate Morris sadly people want entertainment and not actual mechanic information

[@TheCarPassionChannel]

+Aawe Ewaa So what you're saying is, if I start doing hack jobs and street hooning, I'll get big? :) Too bad for me!

[@aaweewaa389]

LOL im not implying your not big already, i love your channel man I'm buying a miata soon to turbo. But the videos that gets the most views have the words "ricer" or "ricing out my car" in it and most people are looking to laugh at dumb childish jokes(car stuff) or see cars get destroyed, other then to sit and listen to and intelligent person talk about how to properly work on a car. if you don't feel "big"enough as a fan i can give you tips to try and get more views/ attention -my rant

[@TheCarPassionChannel]

Aawe Ewaa Nope, I know exactly what you're talking about. And I can tell you that my channel will never be like that, I wouldn't change my style just to get bigger. I just really like teaching people about the things I know about and like getting all of the positive response. A few thousand devoted enthusiasts is way better than a hundred thousand trolls. The channel is growing slowly and that gives me a chance to see all of my comments and respond to a lot of them as well as direct messages, snapchats, etc which I really like. I'm all about keeping it fun and interactive!

[@aaweewaa389]

im glad you see it that way, theres nothing wrong with trying to appeal to the mass youtube car community for likes or views. you dedicate a lot of time to do what you do almost anything you work on a car your taking time to film it all and make sure conditions are good enough for the camera( not even mentioning editing) but i love your videos man you, MCM, engineering explained are my top. when i get another car to work on(miata) i will make videos too purely for how to work on the car :D

[@gnarrang6008]

The ppf alignment should be checked after reassembly.

[@contents_of_the_subconscious]

Nice Merc Wagon at 0:08

[@lukamatijasevic890]

@ Greg I also removed upper pressed spacers , cuz everything was rusted and it was easier. BUT !!!!!!!!!!!!!! Mazda manual says you basically ruined your ppf by removing two inserts and now you need new one....those two inserts need to stay in ppf. Its a little harder to remove diff correctly. So good tutorial video...but you should mention this or add a text in a video at 3:50 mark...its not very likely that you will damage the splines on inserts, but that can happen, and it happend to quite a few people....and after that you basically need new ppf.My advice would be to use little blue loctite on those inserts, a be careful when pressing them in. I did a nut and bolt miata restoration so i know a few little things where you need to be careful.Other than that keep on.... great videos :)

[@TheCarPassionChannel]

+Luka Matijašević Thanks man, that's why I like to put in some of my videos that I'm not a professional! I've added an annotation to the video and will add the information in the description as well.

[@lukamatijasevic890]

Didnt bother to look time difference beetwen usa and germany so you have almost the same message on facebook..haha you can easily miss a comment here

[@lukamatijasevic890]

+TheCarPassionChannel If you did it like this two times...which i guess you did (you swaped vlsd for torsen) it wuold be good to mark bolt and inserts position, and inspect it once a while. And since the car is boosted, ppf could go wrong earlier :)

[@Giabtovka76]

what is the proper way to remove the ppf then?

[@ianrwin]

6 years ago, your channel has come so far, but your old content still delivers. Got the info I needed, and got some good bloopers at the end 😂

[@TrevorCazes]

I drilled the centers out, then took a flat head, hammered it straight down the seam which caused one side to fold in, then the halves popped out with one tap. Didn't even mar up the housing.

[@seancutick559]

i’ve been hammering a flat head for over 3 hours and i barely have a centimeter of the bushing out. kill me.

[@TrevorCazes]

@@seancutick559 did you drill it first?

[@TottoZ]

Cool video, I'm subscribing to help you grow man, I just started youtube'ing and is currently working on my Toyota Mr2 (which I bought instead of the mx5 miata)! I'm trying to to as much of a serious fun interactive channel as I can and not like those "ricing my car" sort of videos! :)

[@beeoracle8254]

Did anyone else experience vibration exponentially driving above 75 mph after installing these differential bushings?

[@scottyknows1566]

Two things I did different.. Leave the one piece axles in and drop the whole thing. And get an actual chisel about 10 inches.. And a 5 pound sledge took 10ish hits maybe and didn't have to drill out anything..

[@mattman2314]

Bummer that GarageStar went under. The link no longer works. Still a great video to show the process! Dude your videos helped me so much!

[@georgerodriguez5468]

my PPF bolts are completely shaved off umm I’m fucked

[@diegoreyes2212]

So I recently got a hard top and I've been getting wind noise through the driver side window (vertical side). Wanted to know if you've experienced this before or any other sorts of noise with a hard top. Great video btw. I have notifications turned on for your channel so I never miss one. 👍

[@sfish6]

I used prothane bushings since those are the ones moss has, and I did everything in this video (thank you btw) but I hear a clunking noise coming from the back when i accelerate, anyone have any idea why?

[@jmpcrx]

First mod I did was torsen lsd, only had the car a couple of weeks with no knowledge of the car,, that ppf bar thing was a complete bitch.

[@iamspiritus6206]

Man im trying to find these bushings but cant seem to buy them any where 😑 & I just got the RX 7 FC housing done too...

[@caseylockwood5512]

Yet another awesome video. Are you going to do an engine mount video? Perhaps a header install video? Both would be awesome to see!

[@TheCarPassionChannel]

+Casey Lockwood Engine mounts will be very soon. I will show the installation of the turbo manifold on B&B which will be basically identical to a header install.

[@AdvBrewery]

Just a general tip as well, always break your fill bolt lose first! That way you know you can refill your diff, so you can drive your car somewhere to get a better tool for more leverage etc if you can't loosen the drain. Great video!

[@ollydubhead]

Oh no......i'm completely out of breasts..........!!

[@MoreBo0st]

Great diy man I'm a Vw guy but still enjoyed watching this video. oh yea and I herd a mint r32 pass by when you were putting the diff back in 👌

[@AidanMorris]

How reliable is the B&B going to be? Because I'd rather spend less money and do what you're doing but I'm also considering the voodoo 2 kit and begi shanghai S kit. Thanks if you respond!

[@TheCarPassionChannel]

+Aidan Morris Well, if I can get it tuned well, it will be reliable, but that will be the challenge. There are many others that have done what I'm doing so it's not really sketchy or anything if you do it "right." If you want 200+whp and maximum reliability and safety, I would advise starting out with Megasquirt in the first place.

[@wwilliams1358]

Tried going on to GarageStar's website, but I get a connection error, saying to be sure the link is correct. Did a search on them as well, and get the same error message. Did they change their website address? No longer in business? Great video as usual, and yes I am years behind all your videos, just starting to get interested in obtaining a Miata and tinkering with it.

[@TheCarPassionChannel]

I believe they're primarily only making seat rails now for various cars.

[@DustyMacsGarage]

Made it look easy!!! Awesome video man!!

[@williamorellana369]

I have a question. Do these delrin mounts use a lower one as well or just the stock lower portion? I know some have the upper and lower delrin which you then have to remove some rubber from the stick lower mount.

[@TheCarPassionChannel]

These use the stock lower mounts, and that's probably the reason that there's barely any increase in vibration at all

[@CharlesGrenades]

Offtopic but what offset are those wheels? Thanks in advance

[@TheCarPassionChannel]

+Sam Newman +16mm offset

[@derksgarage]

Removing the old diff bushing makes me want to eat mountains of day old taco bell for breakfast and then sit through a 3 year old's my little pony birthday party WITH NO ACCESS TO A BATHROOM.

[@asice716]

Can i do this without changing the diff fluid? Just replaced it less than a 100 miles ago.

[@TheCarPassionChannel]

Yes, but I'd still advise draining the fluid. Then just put the same fluid back in.

[@TimVo]

No modification is necessary to the differential retaining plates?

[@TheCarPassionChannel]

+TheCarPassionChannel I'm looking into a 1.8 diff and have a good deal on the whole carriage, subframe, axels, driveshaft, suspension and brakes. All together for 200 out of a 1996. How do I know for sure its a torsen lsd before I buy it and put it in the car? I'm also following Broke and Boosted and doing a budget turbo build myself! Always waiting for your next episode!

[@elwindewitte]

Finally replacing these as well! Found that cutting the sleeve for 1/5 worked really well! Just drive a screwdriver in-between the cut part of the sleeve and the housing, and it just pops out

[@mer5931]

Best teacher

[@TrevorCazes]

When you reinstalled, what did you set your ppf measurements to? Ever since I installed my diff bushings I get horrible vibs at 80+ and I'm wondering if it's because of how thick the top of the bushings are....that would make the diff sit lower there for increasing the drive shaft angle....

[@prostreet1032xx]

Hey I watched your garage star thermostat sandwich review and I am very curious on how to wire it. I've searched everywhere on youtube and I can't find any videos on how to actually wire a sensor and get power to the gauge in the engine bay. I think a video of this would be very helpful to people who want to purchase that product ( and me ) haha

[@frankfitzpatrick5300]

I am also thinking of going Rotrex but I would have to upgrade Clutch , engine mounts & diff . bushings etc. & im not sure I'm ready to do all that yet . We'll see ? . But it would be stealthy quiet & confuse & embarrass a few faster cars Lol Did you ever ride in or drive a Rotrex Miata ? Or know anyone who owns one ? Thanks Bro You have a well sorted MX-5 ! Brilliant job !

[@WigglingWaffles]

i know this is an old video but a trick for getting one piece axles out, because sometimes the circlips are pretty well at home in there. Take a large box end wrench and put the outer jaw on the axle lip then use the sidemost blade/fin of the diff as a pivot to lever the axle out. Way less effort than using screwdrivers sometimes. Or maybe you're like me and are too lazy to get up off the floor to go get them and use whatever's in reach.

[@ultrawidegaming9609]

is removing an open diff on a 1.6 the same method? if I wanted to swap in a torsen

[@TheCarPassionChannel]

+lance thurmond Yes the process of dropping the diff will be nearly the same, actually a little easier since the 1.6L diff is lighter, and has 2-piece axles so you can just unbolt them.

[@realfast7274]

You are awsome for showing the step where you pop the axles into the diff. I thought my axle was busted until I saw your video.

[@Dcurleyfry]

Nice video as always man, I might have to pick up a set of these someday when I do the 1.8 Torsen into my 1.6

[@Thatkswappedek]

Just ordered mine few days ago..changing my diff (4.3 to 4.1 on 5speed) so thought this is best time to do it. Thanks for showing how to do it.

[@cameron2325]

You keep mentioning they help everything not torque over as much, but in my experience the motor mounts solved that, the diff bushings helped most with wheel hop and a little smoother drifting/sliding. Great video!

[@str8slayn1]

Of course. I get delrin diff bushings and look on KZbin for a video on them and Old Grep pops up first. Alright bet.

This was done on the car when it was 1.6 so you already know it's proven

Wish I would have watched this earlier, as I just bought Mazdaspeed bushings. As with all of Greg's vids this one is Very Useful!!! (as well as well done) I am Very Grateful to Greg for his hard work and Outstanding info! 5 stars!

[@cameronclark1056]

Hey Greg, not bringing up at 3 y/o video to annoy you but I did this bushing job to my car about 2 or so months ago, put everything back together and thought I was good. Turns out I dont have my axles all the way in and my diff leaks horribly and I cant seem to get them to fit in any advice would be great!

[@TheCarPassionChannel]

You have to give them a good shove to get the clips to pop into place usually. The leak might be from the axles not being seated, or you might need new seals which are very easy to replace. If you just take out the 14mm bolt that holds the upper rear control arm to the hub, and loosen the long bolt in the bottom of the hub (so the hub can pivot) you can swing the upper arm out of the way and use the hub itself like a big slide hammer to bash the axle into place. It takes a little force sometimes but they should pop in all the way.

[@cameronclark1056]

@@TheCarPassionChannel thanks for the response, I prematurely replaced the seals before I realized that the axles weren't in place so that's already done I guess I'll go at it again, already tried the hub method and the mallet method maybe I'm being too nice to it LOL

[@crawford323]

I was wondering how someone was going to have to deal with this. Miata also had one of the bushings purposely softer than the other. This was done so that when you lean into a turn inside rear tire actually rotates slightly into the turn also. The transmission to differntial brace stopped the problem due to power being applied but the purposeful soft bushing was an ingenious handling design.

[@csbeverly1]

installed these along with a Miata roadster shifter, well worth the effort!

+TheCarPassionChannel thanks dude

[@Giabtovka76]

So I just did the same thing to my car however now in neutral if I rev the car it shakes is this because the solid diff bushings took out the slop and the worn motor mounts are more noticeable?

[@TheCarPassionChannel]

Danny Kim Yes this is completely normal, the diff will translate a little extra engine vibration with these bushings.

[@Giabtovka76]

TheCarPassionChannel also how can you tell which NVH is caused by the delrin bushings and which are caused from other things? At 75mph there's a noticeable vibration (even more so) and it will shake the tach needle up and down. Also I have a whirring noise at low rpms in the city is that normal? Thanks

[@MFETmusic]

hey mate. did you bushes not come with a bottom part? my bushes were 2 piece and I had to remove the rubber off of the disc mount plate things great video though.

[@TheCarPassionChannel]

+Project miata mx5 eunos roadster Not with the GS bushings. They keep the stock rubber ring things on the bottom, and I think that's why there's not a big increase in noise. I have a friend who had delrin diff bushings that were solid mount and he said it would rattle his brain, he went to ES bushings or something else.

[@MFETmusic]

I see. Thanks for the fast reply. I have the super pro ones and had to cut the robber off. I only have a tiny bit of a rumble at about 4k but I think that might even be down to me not lining up the ppf correctly. Can't wait to see how to change engine mounts though as I think il do that before fitting the turbo.

Hey man, what exhaust are you running on the car? Do you have any dB ratings at your local autocross that you have to adhere to?

Hopefully you can answer my question before I figure out how to do it myself but. I currently have a 1990 1.6l na miata and i also have a 1994 1.8l na mazda miata. ive been swapping part from my 1.8 to 1.6 and recently ive installed my torsen lsd into my 1.6 miata. I have everything mounted into the car so far except for the axles. Reason for not have the axles in is because for some reason the "slide in" 1 peace axles wont slide into the diff. I think its because they have the little ring on the end of it and it wont push threw passed it but still would like to hear if you have ran into the same problem

[@TheCarPassionChannel]

Noah Bailey They pop in, sometimes it takes a little force.

[@22quack]

I think I just need to stop doing upgrades until you do a video about installing them lol Tip that I recommend is to remove your fill bolt BEFORE you remove your drain bolt. The two main things this does is make sure that you're able to fill the differential back up again, and it also allows you to drain the diff quicker and more smoothly.

[@TheCarPassionChannel]

+Ross Smith Yeah this has been mentioned a few times and is a really good idea! Worst case scenario you could fill it through an axle hole. Not as accurate, but it would work okay.

[@griffinbooher292]

Sorry dude I know I asked a spacer question on one of your last videos...but in this one I got eyes on 'em...when you purchased yours, did they come with lugs or did you have to buy separate? Or, if you have a link to your setup that would be killer...love the look. Keep up the good work man.

[@TheCarPassionChannel]

+Griffin Booher They came studded, with lugs, in the Miata bore size so they're hubcentric as well. I also have the rings that match them up to the wheel so the whole system is hubcentric.

It seems like a lot of work trying to pry that metal sleeve out of the diff carrier. Why not take a socket and hammer it out like the bearings? Better yet, invest in a 6 ton H frame press?

[@TheCarPassionChannel]

+tyau1234 Read description, turns out it's better to not even remove the sleeve.

[@48763405]

It made less difference than you expect, right?

[@TheCarPassionChannel]

+zj120cn To be honest I was not expecting a huge difference, I filmed the diff itself rocking and I knew it didn't have a lot of slop compared to the engine/trans, but in my opinion it was definitely worth the upgrade as I hardly notice any difference in noise.

[@48763405]

Good work man. Wish you could finish the build soon and post videos more often

[@TheCarPassionChannel]

zj120cn I actually just started a new shorter work schedule which will leave me more time for videos! I had a B&B episode planned over the weekend but I hit some snags so I couldn't do it.

[@x332433]

hey man, do you just leave your car outside?

[@TheCarPassionChannel]

+ricky fillapill Yeah and I sleep with one eye open

[@RetroExhibitCollective]

Yeah I leave my Miata outside...I just got my hardtop stolen and the driver side window busted. Make sure to get hardtop security if you got one. Me and two other guys got their tops stolen the same night

[@x332433]

and to think people who steal these miata parts might have a miata themselves..

Hello! Getting ready to do the shift assy rebuild in one of your previous videos. What oil do you recommend I use to replace the current crap fluid in there?

[@TheCarPassionChannel]

+Chris Ahmed Any trans fluid will be fine, it's just to lubricate the shifter so there's not a lot of heat or stress.

[@shauneasterbrook5089]

Day feels complete, been waiting to watch this all day.

[@5150LouieB]

Are you going to be going over the oil lines for the T25 install for B&B when you get to it? Another great video man! Keep them coming!

[@TheCarPassionChannel]

+Louis Benevides Yes I'll be going in detail on the oil and water line routing/sizes/etc.

[@MitchRiedstra]

Thank you so much for this!

Noticed any difference in terms of wheel hop? Awesome vid!

[@TheCarPassionChannel]

+ErbiRacing Well, I don't really get much wheelspin to begin with so it's tough to say. Also, with this much power, and tires as sticky as mine, wheel hop kinda likes to explode transmissions, so I drive to avoid it as much as I can, haha.
