[@stevesimone1104]

"Ideally you should have the pattern a little further down". That's right, so take it apart again and increase the pinion shim thickness. And don't grind the pinion bearing surface. Sorry, but this is the difference between a regular mechanic and a true professional.

So, why are you watching this video?

[@BroadcastBuddy]

Also don't take a die grinder to the pinion surface. I lightly scuff with emery cloth to remove the oxide. You want some press fit on the outer bearing so it doesn't spin on the shaft.

[@kevin_nagle]

I do the same with emery cloth

[@coltonstevens1]

Yeah and he pried the cover off with a screwdriver and definitely bent it. And he chiseled into the gasket surface. And he is one of those guys that thinks you need to mark an independently balanced driveshaft.

[@davidyj9013]

Always, always, always amazed at how easily stuff comes apart on these instructional videos. I've NEVER been able to remove a pinion seal in good enough shape to reuse it! Unfortunately I live in the real world so my stuff takes a teeny, tiny, tad more elbow grease and grunt work. When rotating the pinion gear after install, you showed 25 on the torque wrench but didn't explain very clearly what that was for. I believe you were showing 25 inch pounds which is pinion bearing preload, or how much effort it takes to turn the pinion after properly collapsing the crush sleeve. Also when showing removal of the C-clips, turn your cap around or remove it so the brim isn't blocking the camera so we can see what was actually happening. I think that's what these instructional videos are for - to see how to do stuff.

[@bucksnortbumblefuk6872]

This is advertisement bud. And horrible at that.

[@merlepatterson]

Also, the shim depth might change on a new pinion and it should be installed without the crush washer and preloaded to do a paint check on proper gear mesh to know if you have to add or remove pinion shims before the crush washer is set permanently.

[@alananderson2961]

What would the parts and labor cost be to do this job.?

[@nickrangel139]

No press? Emery cloth the pinion, put the freezer. Put bearing in oven @ 400 for 1/2 hour. Stand pinion up, and drop bearing on with tongs. It will slide right down making a cool hissing noise. After using this method I found all kind of cool uses for heat and ice.

[@boost1728]

I'm pretty surprised you let it go like that.. the contact patch definitely should've been adjusted closer to the center of the teeth.

[@bucksnortbumblefuk6872]

Hacks man. They are everywhere

[@81brassglass79]

He let it go with old axel bearings and seals...

[@stevesimone1104]

Agreed, he didn't want to go through the additional work of re-shimming the pinion.

[@kevin_nagle]

this was one of those "good enough for the camera" install videos. Amazingly got the pinion preload correct first shot 🙄👌🏼 Lookup EricTheCarGuys 8.8 rebuild video for a real life situation. He spent hours upon hours fighting preload & contact pattern issues - he must have had the carrier out of it a few dozen times.

[@Shogunersash]

@@kevin_nagle Great reference 👌.

[@BroadcastBuddy]

That is why you don't install the crush sleeve and apply rtv to the companion flange assuming the pattern will be good. The pinion shim may be the same for new gears but unlikely if you want a good pattern. I had to add 7 thou deeper to get a good pattern to the toe and that was with new Ford gears.

[@blakenorman4822]

Right you want to check pinion depth first right? How do you do that without installing crush sleeve, you just dry fit pinion in and check depth?

[@joshanderson3716]

My favorite part was when he: !"GROUND THE PINION"! to fit the new pinion bearing.

Back lash is measured at the heel of the ring gear. I wouldn't recommend sanding or filing on pinion so bearings go on easily... Could try warming bearings up in the oven or chilling the pinion with liquid nitrogen or use the press. Great video none the less.

For all you saying “looks easy enough”. The hardest part is getting the pinion depth right. He didn’t get it right in this video and just sent it. You either buy an expensive tool to measure or you trial and error several times.

[@cintiabako2531]

Great video on the install, nice level of details. One question if someone can answer. The backlash was measured on the ring bolts in thsi video. In the FRPP isntall manual shows the measurement should be taken at the middle part of the ring teeth. Obviously the larger the radius you measure the larger backlash will be measured for the same angular backlash. Therefore it is important to measure on the correct radius.

[@kamalkathiwoda1007]

Cintia Bako

[@allentraylor5659]

Back-lash is: gap/ slop / free-play ..etc. If you hold pinion and move ring-gear it doesnt matter what you reference on the carrier as it moves with the ring-gear..... Measurement will be the same.

[@okhotrodder]

Everyone, be prepared to take all day doing this. Good time to replace your wheel bearings also. Carrier bearings never just come off. And getting your spacing right is crucial if you don't want a whine. I always laugh though when people say take your pinion back off and replace the shim. They say the crush sleeve is one time use. If that was true, they wouldn't just give you one sleeve. I've never had a failure from taking the pinion nut/pinion off several times. And a whine usually only last until the gear is worn where it's set. I've did many truck axles where time was an issue so we just slapped stuff back together. Never had a new set of gears break because of a whine, and 1000 miles down the road, the whine isn't noticeable. Besides, when you are use to a major whine in rally cars, a little axle whine is nothing. This job is easy the more you do it. The carrier bearings are the most frustrating part. Doing another axle today.

[@gregslo5oh575]

You seem to know what you’re talking about lol! I have an 8.8 and I cannot seem to get the crush sleeve to crush all the way because there is a lot of resistance when I try to tighten the nut. I had a 2 foot long breaker bar, along with a homemade 1/4” thick steel flange holder and I snapped my homemade flange holder in half trying to crush the new sleeve. Do you have any thoughts/ recommendations for what I should do?

[@garlandjones7709]

What kind of truck axles are you talking about?

[@1968JaguarXKE]

This was a great video, I learned a lot, I always thought that High ratio makes the rear wheels turn slower giving you more torque at low end.

[@egibson2266]

would it be a good idea to paint the gear before removing the existing ring and pinion? you removed the gears and measured all the shims assuming they were correct. judging by the pattern on the new gears, it seems the pinion depth could be a little off?

[@lol123321123321]

The die grinder to the pinion killed me 🤣. I also remove the black oxide coating but by hand using fine emery cloth. All you need to do is take off 1 thousdands of an inch, just the coating. Die grinder way overkill imo

[@charlesboiteau179]

When you change to a numerically higher ratio, the rear wheels turn slower, not faster. This is why numerically lower ratios are used for higher top speed.

[@quietstorm8230]

I found if I set backlash, without the carrier torqued, once I torqued it, it would be tighter.and with a pattern like that, I would have thought you'd need to have the backlash a little decreased, it's on the top edge, it looks to me, like it needs to be more centered.

[@patrickhoj6542]

Hey Bill, great video and mechanical expertise! In your experience doing this, can you comment on the most common problems a first timer may have in this situation (has had), and what the key problems tend to be with this particular work? I thought I would check, as I have done everything else on cars and trucks, but never worked with the rear differentials; honestly, as people often cautioned to stay away from it. So, on the typical 8.8 mustang rears, what are the worst horror stories you may have heard? I would like to know so that I can hopefully add some more attention in such areas of the gear changing process. Thanks.

[@Zerogivengarage]

It is not a job for a first timer for sure. The thing most people get wrong is setting the backlash. If it is too tight or too lose you will get excessive noise and wear on your gears. Take your time to make sure that is correct.

[@patrickhoj6542]

Bill Tumas , thank you! I can see where it would be all too easy to let a few thousands go on the backlash, get it finished, then run into a world of hurt later on. It certainly seems worthy to prepare and take all the time necessary for this or just pay for the install. I can sure see the need for an accurate dial indicator, and in proper solid placement as well on this. I will be going from 273's to ford racing 410's on my auto. Beyond that, I absolutely appreciate your advice, and thanks for the great video!

My Ford FSM says 8-15. Ideal backlash is 12-15.This is for all late 90s 8.8s, except IRS which is 10 ideal. After 150K the explorer gears (measured at 14) look new and never had noise. Maybe factory gears are different

I ended up setting it to a 9-10 with a perfectly centered pattern. I had a small driveline clunk in the Explorer in certain deceleration circumstances - completely gone now. I always thought it was the two piece driveshaft spline thing. Either it was the backlash or the 75W140 that stopped it. I still wonder why they would put stock 4.10 gears in that OHV V6 milkwagon!

[@griffon3275]

replaced many a ring and pinion in ford and chevy and every time replace the axle seals ..they are cheap and easy to replace and cheap insurance against seepage. also the shim behind the bearing on pinion you need to get from the old gear set is a must and always told that re using it is perfectly fine if using ford motorsport gears in an 8.8 rear end if using another manufactures gears you need to use pinion depth checking tools as the ford motorsport gears and the oem gears are the same and the shim will hold true to spec .. also one thing noticed when removing the front pinion seal and bearing there was a shim there as well ?? I dont ever remember there being a shim there in any of the rear ends I have ever done ? shims only behind pinion gear bearing and side bearings ? was that shim because of aftermarket carrier ?

[@griffon3275]

one last thing... the factory rear end fluid is synthetic and high quality on low mileage rear end gear changes for friends I have filtered the old fluid with a coffee strainer and put it back in and topped off with new fluid if low.. this is not really being cheap just being practical the fluid will last at minimum 100k miles if not more and does not break down over time just gets dirty as long as you strain it to remove any contaminates it is perfectly fine to re use as long as it is the OEM fluid ... saves you about $60 on the swap .. Also I only replace the bearing on the pinion gear because I will not re use it after it was pressed on or off as it may become distorted if re used.

[@griffon3275]

also do not follow this directions because it is very very incomplete as it does not show the checking gear backlash step or the crush collar for proper preload steps which if you follow only this video you will trash your rear end gears most certainly and watch the beginning he even points out that he is not covering everything and leaving out some shit which is VERY VERY important .. do not use this as your only source for gear change

Hey I like your style. I’m building an 8.8 for my 85 mustang 347 6 speed with 4:30 gears and a 31 spline ford carrier. I tightened the pinion to 25 inch lbs and when I spin the carrier and ring gear it feels a little tight. Is that normal? Is it true that the bearings will break in and everything will loosen up? Thanks for the help and I like your style installing gears. You seem very confident compared to others I’ve seen. Some videos will drive you crazy if you go their route.

Hey Bill what size bearing race installer are you using for the inner pinion race?? I have an 81MM (3.18) size and will not fit all the way in and seat. the smaller size down is to small.

Awesome video Can my 2015 F150 XLT 5.0 with Stock 3.31 gears and axle accept 3.73 or 4.10 ? I want to install a 6” lift and decent size (lg off road tires) I have read from others that my stock gear set up will have drag with the 6” lift and large off road tires 😢

Your truck will have either the Super 8.8 or the 9.75 rear end. Both can accept different gear seats. If the diff cover is symmetrical it is the 8.8, if one side is larger its a 9.75.

So I noticed on another video you have tighten the pinion down to crush that sleeve. I put mine together watching your video where you don't do that. do I need to take it all back apart and tighten that way down or something?

Appreciate the insight.

I would never reuse axle seals and if my mechanic did not replace them while he already had it tore down and they started leaking with in a year or even 2 of having all that work done they would no longer be my mechanic. What $15 seal and 1 min of work while its tore down or the same work later only have to pay you to change the seal and have to pay for all the same work over again.

What’s all been done to the mustang performance wise?

Hey Bill, if we are just changing the axles do we need to do all the other steps?
