Hi Everyone,
First post so go easy on me,
I just finished rebuilding the 8.25 IFS on my AWD 2004 Cadillac Esky, I followed bigredmariner's guide, so a big thanks to that! This is by far the biggest thing I've ever tried to tackle mechanic wise.
I took the esky for a test drive, and, there was still a wump wump or grind grind when I turned right. And when coasting ie slowing down, there was definitely some noise. Under power and straight, everything was fine.
When I took it apart, the tab portion of the lock tabs was entirely gone, and the carrier bearings shot. I thought everything else looked good though. I went ahead and replaced all bearings, and got it put back together.
My final backlash was right around 0.009", a little high. And I'm not sure I had enough carrier pre-load. Carrier plus pinion read 45 in-lbs, but I had a really hard time cranking down on the carrier adjusters. Thinking back, I should have unbolted the case and adjusted with them loose.
Anyways, is it possible I have something else going on? Doesn't sound like a CV joint, but maybe I just don't know what that sounds like. Is this what new bearings would sound like if I didn't have enough carrier pre-load from the get go?
I plan to take it back out and pull it apart to look, but I'm not too hopeful I'll be able to tell. In the end, I may just end up buying a rebuilt unit, which has been my back up plan the whole time (since I'm new to this)
Any help is appreciated, thanks!
