I have had problems in the past with my AWD, but usually it was not unlocking, now it wont lock in at all.

I have changed the fluid, the light does come up on the gauge. Yesterday I was tring to backup and no matter what I did it would not engage in reverse. It seems like sometimes it will go in in forward but not like it is supposed to.

Any ideas? I have a feeling this is going to be expensive..

roller cage.has been covered in here alot

I spoke to the dealer, and he said that I should replace the entire diff? I have heard about the cage and how it does fail.

Anyone know or have the pages for the removal of the diff? I would liek to do it myself to save but I dont have a service manual.

THanks

It's basically pull the two axles, output shaft a few bolts on the underside, unplug and pull it out....
