Help! For those of you who regeared to 4.88

[PoRunner]

So i bought some G2 4.88's for my 00' Runner and I am running into a couple of questions. My first question is, What sets the pinion depth? Is it the crush sleeve or the shim in between the large pinion bearing and the pinion itself? If it is the shim, Toyota offers a ton of different choices. What sizes have people used in the past? Any input would be greatly appreciated. This isn't my first time setting up gears but I just want to make sure it is perfect. Thanks!

shims are used to set the pinion depth.

the crush sleeve/spacer is for setting the pinion bearing pre-load.

Do you know if the stock shim will allow the pinion depth to be correct or will I have to add or subract some? From what I am reading the stock shim seems to work most of the time but I wanted to see if anyone has a personal experience with it.

this will vary from set up to set up... you really wont know untill you set it up and look at your pattern, then adjust as necessary. what works for one might not work for the other....

its generally a good idea to START with the original shim.
then adjust accordingly.

I am seeing that it is a good idea to leave the crush sleeve out until I get the desired pinion depth, my question here is how tight do I want the nut on the end of the pinion? I'm assuming I'd want the nut tight enough so the pinion doesnt have any play in it.

It won't be easy if this is your first time,but if you are patient and have time to do it i say go for it.most pinion depth is already measured during initial build up the only time when you need to adjust it is when re gearing most gears will come with some kind of marking to the pinion (+,-) followed by a number this will indicate if you need to add or subtract from your current shim thickness.

Your pinion bearing preload should be between 15-30 in-lbs of turning torque,the initial torque would be around 150-200 ft-lbs to crush the sleeve.once you set the pinion bearing preload you can start setting your gear backlash and then check your gear pattern.you will also measure you total turning torque once everything is set it should add 10-15 in-lbs from your initial pinion bearing preload.you will need a good vise or a jig to hold the 3rd member.good luck on your quest.

I've got an extra solid pinion spacer and shim kit if you want it on the cheapppppp

What different sizes does your average shim kit come with?

This is what I have, for the V6 obviously:
Solid Pinion Spacer Kit | Marlin Crawler, Inc.

Still in the original plastic wrap.

Are there any special tools required to regear the 3rd member or the front clamshell? When the time comes I want to do the install myself if there's nothing out of the ordinary required.

You can do it without dial indicator with a magnetic base, but I'd get one. I'm pretty sure you can still get them from Harbor Freight, but not 100% on that. My biggest suggestion is to take you time, you're not going to get it right the first time.

For the third member you need specialty tools to get the preload on the carrier bearings correct. Everything I have read recommends near 150ft lb. I made some myself in about five minutes that work excellent. I haven't started the front yet but I am going to assume it's not going to be any more fun than this rear has been.

ive set up quite a few rear ends, both re-gears and just bearing replacements. ive only used basic shop tools, and a micrometer for measuring shim thickness.
it can be done without the special equipment.


that said, I would REALLY like a case spreader, as well as a few other things.
I plan to get them soon, before I re-gear my 1 ton running gear.

Alright so during my setup I was having trouble getting a good tooth pattern on the ring. The original factory shim is .080 and was not even getting me close to where I needed to be. I am now up to .203 and it is looking more favorable. Does anyone forsee an issue with this much space? I found a link on gearinstall.com that said the stock carrier for 4.10's where casted different than the carriers for the stock 4.88's. Thus requiring the pinion to be shimmed 1/4" closer to the ring, which is .250 if my claculations are correct. Anyone run into this issue?
