Rear Differential Help Please

[creeg]

hi everyone-

I am looking for some help with my rear differential. It looks like the bolts holding the ring and pinion came loose, and I need a new ring and pinion as a result. I found NOS on isuzupartscenter.com, but they are pricey. Anyone have a line on anyone else who has them?

Also, my mechanic is having a hard time finding a differential rebuild kit. He seems to think that the kits that he has found online have the wrong crush sleeve.

I looked on Rock Auto, and the kit on there, DRK320, my guy claims is not the right kit for a 2001; specifically, the crush sleeve is the wrong one. Can anyone confirm that?
To add to the confusion, there are 2 kits for 2001:
Rear; 7.63 in. Ring Gear - 1st Design - 1.5 in. Seal I.D.

And
Rear; 7.63 in. Ring Gear - 2nd Design - 1.69 in. Seal I.D. (this is also out of stock)

Any help is appreciated.

Thank you

So the ring an pinion on isuzupartscenter.com would need to come from Japan. So that is out. I have sourced another one in the states. My questions still stand about the crush sleeves.

Measure the diameter of your pinion shaft? That should tell you the right seal and kit to use if they changed the diameter of pinion?

Anyone else agree?
