Hey All:
I've got a 489 carrier and am experiencing some weirdness. I bought a used A body 8.75 from a pretty well known Mopar vendor. The third member was supposedly a "known good" unit. Needless to say I got the car together and the thing is making all kinds of noise. Whining on acceleration and decel, vibrating, etc. The carrier is actually a 489.
I pulled it apart, and some of the bearing are pretty grotty, and it dumped a load of small (1mm) fingernail clipping shaped filings when I pulled the pinion.
Currently the pinion bearing is still pressed on the pinion. I measured it right by the bearing and my reasonably decent calipers come back with 1.480. I thought the 489 was supposed to be 1-7/8? Am I measuring it at the right place?
Here's a pic:
Any help is greatly appreciated.
