Tried searching.....Front diff ??

[trd55]

I am new to the 80's, but am rebuilding the front end on my recently acquired 80. After talking to kurt(cruiseroutfitter) and others, I might need to replace worn spiders. Drive plates look fine, as do birfs. No noticeable wear or slop in splines on birfs or inner side of shafts. I removed the third today and ther is some slight play in the spiders. This is just by feel of course, and of course adding the minimal play in ring and pinion, and add the slop in spiders, etc... there will be some slop in the driveline. Back to my original issue.. How do I get the spiders out of the third. Does the pin just need to be driven out and then "restaked"? I assumed that it would be like other thirds with a bolt that hold the crosspin in place? Thanks with any advice.

Zuk has some good info and pix on setting up Toyota diffs;

Thanks, was not familiar with the roll pin. Just checking. Did not want to mess it up on what looked to be the obvious choice of things to do.

It depends on if it's an e-locker or not. I'm gonna guess that yours isn't locked, so yes there is a pin that you drive out of the carrier, then the crosspin can be removed, and the two spider gears fall out. It is very similar to a mini-truck 4-cyl diff.

If this is an e-locker, the carrier splits in half, there are 8 bolts holding it together, exactly the same as a mini-truck V6/turbo diff (see a pattern here?). It would look like this when you open it up:

You really should invest in a FSM for this truck, there is a procedure in there on how to check the backlash on the spiders to see if they are worn. You'll need a dial gauge with a magnetic base. There is supposed to be a slight bit of slop in the carrier.

Spider gears rarely wear out, I would check the backlash on the R&P before pulling the diff apart.

A '92 is not locked, standard setup, you should be able to R&R the side gears without removing the carrier. I would tighten up the carrier bearing preload while your in there.
