92 1500 4x4 rear end problem

[pavrgv]

the rear end whines when decelerating, I thought I had fixed it how ever, I guess I havent. Also thinkin about replacing the spider gears in the carier. I dont know the back lash these are supposed to have. I have replaced the ring and pinion with a new gm gear.

So my q's are this?

1. what adjustment, do I make to take away the whine

2. how much back lash are there supposed to be on the carrier gears.
Chilton doesnt say???

Thanks

the carier gears don't do anything unless you drive around a corner. did you properly adjust the pinion preload??? the backlash on the ring gear should be around .007" to .011" check with a dial indicator. did you check the gear tracking with grease??http://autorepair.about.com/gi/dynam...2Finstall.html
this site has a fairly good explination of the process. diff gears are a real pain to set up properly i usually just swap in a junkyard one with low miles. chevy diffs are notorious for whinning especially if you have a topper the noise resonates usually between 40mph to 60mph.
