How do you set the front carrier bearing adjuster?

I marked the adjuster when I took it out.
I need to know if there is a procedure for setting it?
I had to replace the bearing cup.

Thanks!

Question about the front carrier bearing

It's pressed on correct?
The only way to replace it is to drop the Front Diff?

Picture of bad bearing cup Front Diff.

This is from the drivers side.
Inspected the bearing and it looked OK , not an easy thing to do.
When moving it by hand it was smooth. Since I can't get the carrier bearing out, I replaced the cup bearing.
Was cheap, $11.00 for entire bearing set from local auto parts store.

Question for steveO: Did you ever find the procedure needed for adjusting your driver side bearing? I have not found it yet in this forum. I'm still searching...

Sorry I did not find this information.

I relied on recording the adjusters position and when I reinstalled the bearing cup I put it back to the same location as the previous.

It must be in the shop manual which I don't have.

Thanks for the quick reply!

I plan to just install the new driver side diff. shaft seal (replacing mine because old seal was leaking a bit). I did not move the adjuster behind it. I marked the position with sharpie, then tried to rotate the adjuster with my finger. Since I could not move it, I will assume the adjuster did not move during or after seal removal.

Just to be sure we are talking about the same thing: I recently posted a photo of the driver side adjuster inside the diff. at the end of the following thread about seal removal:

Better yet I posted mine.

This is the drivers side

The first show the adjuster, with seal is removed.

The second is the adjuster removed and the bearing cup removed.

I did mine this spring, both carrier bearings were shot. it would be a compete waste of time only changing the one drivers side race, you need to pull the diff and do both bearings and seals, and maby even the pinion bearings, to set the carrier bearings it is a rotational torque of the input shaft. Doing that measures the proper preload, and if the one race is pitted those flakes are suspended in the oil and going through all the bearings and gears.
