Toyota Gear Install, IFS and Rear Drop Out How To

If you are looking for the most complete Toyota 4Runner and Tacoma Pickup gear install then this is the video for you. Stating with a 2005 Tacoma SD20B 8" Clamshell front with an open carrier, then a rear T100 8.4" rear with a mechanical locker. Then the diffs out of a mid 90's 4Runner starting with the rear TV6 with factory E Locker, and finishing things up by installing an Air Locker into the Toyota 7.5" SD19A Clamshell.
Pinion Depth, Backlash and rotational load is shown and explained using shims, adjuster nuts, crush sleeves and solid spacers.

Ring and pinions are my favorite thing to work on ever since Extreme 4x4 was airing, I like to set my backlash on the tight end so when the gears get some miles on them and mesh nicely they have the perfect backlash then. Thanks for all the great tips Ian.

[@BigTireGarage]

Agreed

[@ryanengle8919]

So true! Power block used to assess my motivation. Sorry neighbors...

[@scottbartlett4853]

I love this, I did all of this on my Isuzu with all the wrong tools. BTW 51:08 your hair looks good, don't sweat the image. The brilliance of Metallica cutting their hair short in their prime means they don't have to keep a long rock-n-roll hairdo into their 50's 60's and 70's. Look at the Rolling Stones.

This is far more entertaining and vastly more informative as opposed to the MT channel's short quips coupled with commercials but we get it why MT has to do it that way. Your doggo is too cool and reminds us of our little min-pin, Gabbasaurus. She passed a couple of years back and your doggo can pass for her twin, just a bit bigger. Cheers!

[@zacharybryant4254]

For the front diff, can you a Torsen diff from the frs/86/brz. It is an 8”. It is 95%drop in. The side gear “may” depending on that application, have to have a it machined for the snap ring on the axles. For carrier bearing, you will need to add a 5mm spacer on one side, and machine 5mm off the the other side. It will require the 3rd gen Supra carrier bearings as they are thinner. Good thing about a torsen, if a wheel that does not have traction, lightly apply the brakes, that Will give a load for the worm gears to engage and drive the tire that has friction. Very smooth and easy on driveline. Last, depending on application, the ring gear bolt holes might need to be machined to a bigger diameter. There are no lock tabs, so use red locktite

[@garychaiken808]

[@BigTireGarage]

Never stop learning

[@rushthezeppelin]

Yup, this just reaffirms that I never want to setup gears. I will eat labor costs on that one, that crap is tedious!! I'll do just about any other work but something about having to take things apart and put them back together multiple times on purpose and not because I forgot something grates me lol.

[@BigTireGarage]

It does take some getting used to

[@RMM--uv7uk]

On the Clamshell front. You didn't replace the inner pinion race.. I really wanted to see how you do this. I do a few of these a month. I ended up making my own tool, so I'm able to get the inner race in super easy now.

[@BigTireGarage]

I did replace it...I just hammered it in

[@RMM--uv7uk]

Yep same way I use to do it. Its very difficult.

[@BigTireGarage]

I find that as long as you have it lined up right and don't let it get "crooked" it isn't that hard...but you need to pay attention to that

I would like to know if a limited slip diff in the rear of a 2000 4runner be worth the cost, truck has an open diff now , and is it the same prosses shown in your great air locker video? Truck has a 3.4 with 4:10 gears 31 in tires and a TRD supercharger , auto trans ?

[@tailorpopp8062]

Awesome as always Btw I think you Facebook was hacked Ian

[@cliffordleach1273]

I’ve watched this video a couple of times trying to get as much info on the clamshell ifs diffs. I’m putting new bronco M210 in my 2020 ford ranger and will be changing the gears. Do you think that diff will be about the same for all clamshell ifs diffs? They have a factory elocker in them. That would be what I’d like to see you work on next!!

[@BigTireGarage]

It would be very similar. I do not have any experience with the new Bronoc stuff yet...but I am sure I will get one into the shop soon

[@Hurst_Hemi]

I have never ran into a problem I was just interested in your opinion

[@116thcavscout]

Would like to see on that chevy or a GMC adding a air locker to the front of it.

[@BigTireGarage]

Clamshell?

[@Hurst_Hemi]

How old do you let your red loctite go before you throw it away and get new?

[@BigTireGarage]

I normally use the red loctite that comes with the gearset

[@Hurst_Hemi]

Ok, I have it in a bigger bottle. I want to say 4-6 oz might be s little more than that

Great informational video and gear install techniques. I would really love to see an Isuzu 10-bolt front axle regeared. If you ever get a chance to install an ARB or TRE locker in it I'd love to know how to setup a pattern. Great videos, thank you.

[@mathewbriggs663]

Have you done or know of any good videos re-gearing a 3rd gen tundra front clamshell diff

[@BigTireGarage]

I don't but the procedure would be very similar to this one

[@armandcasanare2366]

Hello and goodmorning and Happy New Year. I'm New subscribe, so my question is the 2nd Gen 4.0 V6 Tacoma and 2.7 4 Cylinder, is the front Differentials the same as far as external features and Internal Carrier sizes. I blew my front carrier ( 4.0 v6), Toyota clai.s that theres none available throughout the country and they were not sure when will it be available, so i end up purshasing through EBay from the same year 2005 Tacoma 4wD that came o u t of 2.7 4cylinder.FEATURES

[@BigTireGarage]

The ratios would not be correct... but the front differential should be the same

[@marcpikas2859]

I’d like one of those lsd on my 06 Tacoma but at 170K miles I’ll wait for my next truck.

[@BigTireGarage]

Truth

[@andreinij]

Is there a reason you use a bolt and your hand instead of something like the bleepinjeep yoke install tool? When I did my rear end (ford 8.8) I found it impossible to get enough torque without it

[@BigTireGarage]

How I have always done it for 30 years

[@JamesTLangford]

Im wanting to go a different direction with my 04. I want to get away from the clam shell and have the same diff on front and rear

[@BigTireGarage]

So SAS it!!!

[@nickygray4691]

I have a question I have a 1994 chevy k2500 with a 454 and 700r4 and it has 4:10 in the rear what would be in the front

[@BigTireGarage]

Same

[@mrcschubbyboymodels2503]

I have a 98 dodge 4x4 that has that same slip collar on the front axle but on the dodge it's vacuum operated! So I saw a kit that makes it cable operated instead! Still can't figure out why they would make it vacuum operated in the first place?

[@BigTireGarage]

I had that same kit on my Ram 1500....LOVED IT...I wish someone made it for the Tacoma

How do I know what gear ratio is in my truck. 2016 tacoma 4dsb Sr5 4x4 with tow packages .like to put 4.88 gears in it

The gear ratio should be listed on the "option tag" do a quick search online and ypu should be able to find option tag decode info for your truck

[@thebanjoman1963]

WHOA-- Hold on there "Mr Heat Miser!!!" Never set side bearing pre-load with a punch. I was taught to use a proper tool. A piece of flat stock with two bolts to fit in the 'holes' and a big enough bolt and nut in the center and torque it to at least 105lbs.

[@BigTireGarage]

And why can't I set side bearing preload with a punch?

Hi Ian. I own a 2011 Toyota tundra Roock Warrior addition What kind of up grades would you recommend. ? I'm retired and on a Budget.

[@BigTireGarage]

Depends on what you want to do with the truck

[@erice4611]

Where did you get the x .7 backlash calculation from? I had 0.008 @ the pinion flange. I just reused the factory shims that came in it when i installed a eaton E locker in the front of my 01 Tacoma and wired the power into the 4LO safety computer brain for the rear electric factory locker design so it can’t be used except when in 4LO for protection for the Diff and driving safety. Those Arbs seals in the collar with the copper line tend to leak and those 7.5” front clamshell diff are alot of work to tale apart to replace unlike the rear diff 8”/8.25” design or a American diff cover design.

[@BigTireGarage]

That measurement is from the Randy Ring and Pinion Bible.....he checked multiple clamshell diffs ti determine that "rule of thumb"

For the front diff, did you just stay with the current needle bearing setup or changed it out to a bushing? And it is really that necessary to change it to a bushing?

The ARB eliminated the needle bearings....the open carrier I left with the needle bearings...maybe worth the uograde if you were gonna go hard core crawler....but why leave it IFS if that that is the end goal

Nope...just waiting for Garbage day...and that isn't the only exit from my building

[@motoboggin2619]

i fail to understand why people still use crush sleeves. aside from just trying to blindly succeed. their purpose is only to make it less likely to over torque the pinion when finding proper bearing preload.

[@BigTireGarage]

Crush sleeves are not "bad" and they work fine....the solid spacers are "better" but honestly they make setting up a diff way more work

[@motoboggin2619]

@@BigTireGarage ive had no issue without anything between my pinion bearings you can use loctite retaining compound. The differential housing takes all the load of the pinion bearing preload all the time with or without a spacer, unpopular opinion but if you study it for a while you'll see its lack of purpose.

[@motoboggin2619]

@@BigTireGarage ask your self why trailers and full floating axles dont need crush sleeves between the tapered rollers.

[@BigTireGarage]
