Regear Questions

[Aqua-pig]

I’ve done a few, one that went badly. Buy top quality gears and a top quality install kit. Take your time and be ready to set it up and start all over with more or less shims, over and over again. My 9.5 took me about two weekends because I had to walk away several times before violence ensued. Like I said, take your time. If your pattern isn’t right- it’s not right. Once you’ve done one or two you’ll be more comfortable. It’s a challenging project but it can be done. Good luck, keep us updated, holler if ya need any more info.

There’s a few videos on YouTube like this:

More of a reason to have a professional regear your differential.

i just did a 9.5 complete rebuild to 4.56 gears. i replaced the factory G80 and put one from yukon in. the factory shim was to large to re-use, there was probably about .0001 backlash, i had to use the shim kit from the overhaul kit to get a proper backlash.

a re-gear kit comes with a new pinion and ring, you should be able to reuse your eaton no problem. any other questions id be happy to answer, although i am no expert and ive only done this just this one time ( lots of learning mistakes), but the process is very fresh in my mind

The way I remember it, backlash on the 9.5" is set with shims. Bearing preload is set with the screw adjuster.

I think it was one side with shims and one side with the screw adjuster.

I would pay a shop to setup the gears personally. I do everything from engine builds to frame off resto but I won’t rebuild a trans or setup a gear set on an axle. Sometimes your money ahead to pay a pro to do a specific task.

Lame

To the OP - Do it yourself, it's not that hard don't let anyone scare you. You absolutely 100% need the proper tools, but you can do it if you're mechanically inclined

Torque wrench
Dial torque wrench
Digital caliper
Magnetic base dial indicator
Vevor carrier bearing remover from Amazon
Hydraulic press

Then for your axle parts
Master install kit
Extra carrier shims
Extra pinion shims
Ring and pinion

It may take you a while to get the pattern right but it's not that bad. PM me and I will send copies of the instructions from the service manuals as Schurkey suggested

Good luck

are you really asking where to find youtube videos?

No need to be an ass.

Nobody was trying to scare him, but “somebody” was being an ass.

I think it was one side with shims and one side with the screw adjuster.

As I remember it, the backlash is set with shims, then you crank the screw adjuster to get the bearing preload. But cranking the adjuster screw will somewhat change backlash. So there's likely to be a few iterations of setting the backlash and the bearing preload.

This still beats hell out of needing shims on both sides...*cough* *cough*...8.5".

As I've said before...pinion depth and pinion bearing preload are the hateful parts of axle work.

"Some people" are really soft

"Some people" are really soft

Usually the ones that project themselves with a perceived bad ass avatar name.

Some people know their strengths and how much free time they have. I've been wrenching for thirty years, but last year I finally had the opportunity to rebuild a rear axle. It took me about ten hours and was fairly frustrating at times. I won't negatively judge anybody for using the wallet wrench on a rear end. It doesn't make them "soft". A lot of us aren't "hard" because we're badasses, we're hard because we're broke. If I had make-it-rain money I'd readily farm out a whole lot more work.

Over the years, while in the shops I worked in, I heard that some of the worst vehicles on the road are mechanic vehicles. We worked on vehicles 5-6 days a week for other people and only did the bare minimum to our own vehicles. Lots of times, we did not have shop access for our own vehicles and shop at home was limited. I started as a mechanic, was not called a tech till later. Then I ran shops. I liked quality control and found I could not trust most other mechanics to do a repair or maintenance as I would. I also liked doing my own work and not being under the gun to get done by a certain time. I actually like diagnosing, teardown and looking for the problem I diagnosed and the repair that put my mind at ease. My dad taught me the "maintenance pays and breakdowns cost" credo. Maintenance is something you can actually know the cost of, up front. Before I take my dirt nap, I think I will try to do a diff rebuild. Just so I can say that I at least attempted to do it. If need any special tools, I know a very talented diff builder that would lend the tools to me and even look over my shoulder while doing it.
