What am I missing?

[damon]

I am going to be going 4.88s on my 80, adding the front ARB locker, and doing the front axle service all at once. Here is the list of what I am thinking about as of now, any other parts that should be replaced while all that is opened up? Bonus points for part numbers

bearing/install kits for both diffs

Yeah you need pinion shims and stuff. Are you doing solid spacer or crush sleeve?

great question. I have no idea what the differences/advantages are. I am open to ideas.

 

[damon]

I just read up on it, looks like I would want to go with solid. Any disadvantages to going with a soild?

I think the advantage to a shimmed solid spacer is you eliminate the possibility of the pinion bearing preload being loosened up by taking a boulder hit on input flange, causing unwanted additional compression of the crush sleeve.

If you're not sure, I'd talk with whomever is going to do your gear set-up before buying lots of stuff.
I'd use a Toyota crush sleeve unless the solid spacer would be a custom turned one piece unit (vs a shim stack) I'm no gear pro but have seen some super fine shims in use that failed on install leading to later issues.

Good point. Maybe I will just stick with OEM and go with the crush sleeve.

I’d recommend talking to whomever you are getting to do the work and buying not only what they recommend but the brands they want to work with. Also I’d give them the chance to source their own parts. Maybe you’ve already had these discussions

solid spacer vs crush sleeve can be debated but the installer if they are experienced can walk you though what they prefer and why. Andy has some good input here. Both have pitfalls but a crush sleeve isn’t something that should automatically be ruled out. I certainly don’t have enough experience to debate the pluses and minuses of either but have destroyed both

Has anyone actually had a crush sleeve fail? Busting a pinion is one thing but actually over-compressing a sleeve? I've only installed one but the force required to crush it in place was huge. It seems like a good alternative to using shims.

I have had a few fail.

Is your 80 still AWD? or do you have a part time kit?

still AWD, rear airlocked, front open.
