SSTs needs for regearing? (1 Viewer)

[imhighlander]

Hey gang,

My pinion seal finally crapped out completely so I'm using the opportunity to regear as I service both the diffs. In reviewing the FSM I saw a pantload of SSTs listed for the removal and installation of various bits.

How many of these are absolutely essential and how many can be worked around fairly easily with other tools? I tried searching but the threads aren't really indexed for this kind of query (or my search skills are deficient).

Any help greatly appreciated. (And if you've regeared your own FZJ80 and happen to be around the Colorado Front Range, I'd be abundantly grateful for help!)

Check gearinstalls.com for what a very experienced guy does with toyota diffs.

Park bike tools makes a torque wrench with the right measurement range for checking pinion preload. This one is pretty important. "TW-1" IIRC.

You can weld a socket to some flat bar and cut off drill bits as a tool for accurately setting carrier preload.

The OTC 1123 bearing splitter is great for getting the big pinion bearing off/on. This will need to be done repeatedly as you set your shim stack up for correct preload. There are probably cheaper equivalents on amazon.. but I have the OTC version and it is very high quality.

Fabbing something up to hold the third on the end of a bench is worth your time for getting work done on it efficiently.

Beyond that the standard stuff for diff setup.. dial indicator and magnetic stand, pass-through shop press, pattern compound, etc.

If you are not experienced in building diffs, I would recommend going to a pro like ZUK to get the job done. This is not a good task for entry level mechanics. There IS some magic involved.

As mentioned above, typically not a DIY job although it certainly can be if you are willing to invest the time to learn and the $$ for the required tools.

Read this page on gearinstalls. It's a full list of tools you need.

A personal recommendation - we all love working on our trucks, but this is a wildly difficult job, the tools are rare and many are very specific to this work (e.g. you won't have any other use for them, and presumably won't use them often), and if you mess it up, you run the risk of breaking your brand new gears. Plus, from what I gather, the guy who does these installs is very highly regarded here. He was awfully kind to me when I asked him some really stupid questions.

If you do take care of it yourself, definitely post pics. Make no mistake, it can be done DIY, but it's quite a job.
