"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.

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.

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.

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.

Bro I am legit amazed with your Knowledge on cars, so sick. I hardly know anything and am brand new to the car scene but this video was strait epic. Thanks for such awesome content

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.

Very informative! Thanks for posting.

Great video bill, always helpful. Just one thing, the silicon is always preferred to go around from the carrier side rather than the outside or some might have some leaks especially if not cleaned or tightened properly

18:20 When you notice your all time favorite ratchet model and get a warm feeling inside. lol Great video. Should be shown as a learning tool.

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

After watching this video (vs a bunch of others) I feel more confident that I can do this myself. Literally only need one tool beside the press which I'll have to take to a shop.

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.

Gostei mesmo foi do seu arsenal de ferramentas!!!

Did this with my friend in my one car garage with no experience other than this video, it turned out good, and we even upgraded the carrier axles and driveshaft, would I recommend doing this after experiencing this? No 😂

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?

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.

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.

That pattern was WAY too far out to the heel. It's only going to grow off the teeth when that driver stomps on it. ;)

Appreciate the insight.

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.

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?

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.

Is the backlash the ONLY important measurement for installation? I have seen other videos in the past where powdering the gear is done to look at wear patterns of the pinion against the ring gear. Is that not done anymore?

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.

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.

my carrier shims(1992) were just cast pieces, one on either side. is it okay to reuse them?

magnífica información !!!!!

Is the install essentially the same on the 15+ rear gears?

I don't have a lift. Should I remove the entire rear axle? I think that would be easier

what size bearing separator are you using for carrier bearing 3" or 4" or bigger

Eaton specifically says to not use synthetics with a truetrac. Not only that but it's not even Eaton's recommended weight. Should have went back to 80w-90 petroleum-mineral based GL5.

I bought 4.10 gears, and the installation kit, but it will not fit a 2014 Mustang GT track pack. The inner pinion bearing didn't fit the housing too small. Even though it didn't specify that in their description. It say it fits all 8.8 rear ends, also had bad customer service, I end up buy the right bearing for another $120 at Ford dealership.

what's the average cost for a shop to install this?

I'm installing gears on a car with less than 40k miles do bearings still need to be replaced?

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

Did you have to preload the differential?

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.

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.
