Help Rear-end Noise (clunk Not Whine)
Is my rear going south?? i have a weird clunking noise when i make slow left and right turns. when i make tight U-turns that are slow its really loud and bad. i can hear it moer on the drivers side but that doesnt mean its not the same on both sides because i am on the drivers side. i think i read that the differential fluid should be changed, i hope thats it. it probably needs it anyway. what kind of fluid should i use?? synthetic? no additives because lucas oil additives was tested by www.bobistheoilguy.com and they werent too good what should i use. also i think its leaking some oil because i can see it! thanks guys is my rear going bad though? i dont have money to fix that anytiem soon!

I had the same problem. Changing the fluid and adding GM slip additive helped my situation. What's the worse that could happen, you have fresh fluid in there. As far as what type of oil to put in, do a search. There is a debate as to whether synthetics are too slick or not. Read up and decide what you want to do.

Ok man your scaring me about my rear? i hope my spider gears arent going south. i mean its not extremely loud. and when im moving more than 2-3 miles an hour turning you cant hear it. i tonly happens while going slow. i think it is the oil i hope it is at least. my rear holds up extremely well. so i dont think it is giong bad at least i hope not. i am going to change my oil see how that helps

loosen the rear end cover
let all old oil drain out
take off the cover
clean up the mess
put some rtv high temp red gasket maker on the cover
line up with rear
bolt back up
fill up from fill plug
check for leaks?

Mine is doing the same thing, but almost all the time when I am going slow or turning I can hear it. It seems like I can feel the clunking too. Oh well, guess I will have to get 4.10s
if its the spider gears going, 4'10s won't do crap... those are the main ring gears that determine the ratio...
spider gears are connected to the pinion shaft which lowers and engages when you turn the wheel to allow the inner/outer wheel to spin at different speeds when you turn, or corner...

before my spider gears went completely BANG BOOM BANG BANG BANG, HALT
there was a faint sound that showed its face very rarly for 1-2 months before hand...
sounded ALMOST like the parking brake was on... and the power from the car was making the rotors move anyway (very faint, stressed metal bridge sound) and it only happened when i was going 1-3 mph (like backing out of a parking space with the wheel slightly turned...
welp... thats about all i can tell you... hope its not the spider gears...
good luck!
