Tony is from the Phoenix area and owns a 1985 Toyota pickup with 4:88 gears and a Detriot locker in the rear.
He was leaving work one day and had just
turned onto the road when he felt/sounded like it popped and then started
hearing a noise that, after a few miles, got noticably loader. The noise sounded
like touching the blades of a plastic fan and it slowed down when the truck slowed down. So he brings the 3rd over to
my place and the 3 teeth missing off of the pinion is probably where the noise was coming from.

Those of you that have reviewed some of my other links know what this characteristic 4 digit code means...
that this is a Genuine gear...lowest quality gear out there.

These marks might have more to do with the chipped teeth...

There was no CBPL...removing the case to get to the pinion.
|
|
|
Interesting breaks on the long pinion teeth.
|
|
|
The shim on the Genuine was .079"....that sounds about the right value.
|
|
|
Removing the old ring gear...loctite was used on the threads. Good.

The new 488 Yukon gets the same treatment.

I thought I'd try 084 for the first pinion shim value.
|
|
|
I upgraded it to a solid collar...took me 3 tries to get it right. Using a .052" collar shim
resulted in 8 in/lb of pinion pre-load.

Set the BL to .006" and it's ready for its first paint.
|
|
|
drive side...084...quite shallow.
|
|
|
084 coast
|
|
|
drive...092...maybe 1 or 2 thou deep...this is good.

coast 092

I prefer to use the OEM Toyota seals.

Done! :)
