BCan anyone help I have 94 z28 when I turn sharp at slow speeds I get a clicking noise. And if I turn fast around a corner I get a squeaking noise almost like metal on metal rubbing.

 

The clicking also happens when wheel is cut hard in reverse

 

sounds like it could be low on oil. have u check the fluid level? gear could be failing also.

 

Yes I took off the rear end cover and drained oil and replaced it to full because I thought maybe the clutches were sticking and didn't have any metal shavings on the magnet but when finished I still have the clicking almost banging noise

 

And the squeaky noise of metal on metal is a totally different noise and seems to be on the drivers side rear end checked to see if I could notice any wear but nothing visible was there

 

did u add the rearend additive when u changed the fluid?

 

Can I buy it at a Chevy dealer

 

i would think so. ive never used it or had to buy any so im not real sure on that. dealer should know what it is anyways. this is something i found.

Auto zone has what you need, it's a 7 oz. bottle of Posi-Trac additive. Add that in, but you may need to drain some oil if it's at the full point now. Then take it to a parking lot and drive it around in nice easy figure-8's to work it in.

 

my rear end was doin something very similar after i got the car, turned out that my pinion bearings were wore out and wore grooves in where they sit, so chevy replaced the bearings and put the upgraded ls fluid in the rear and its nice and new now,

but i was getting the same sounds you are describing
