noisy rear end
got a 1989 C4 auto , had the auto rebuilt which then left a slight vibration , and the mechanic complained the rear end was very noisy . Had all the wheels balanced , all three drive shafts checked and new universals and new front steel drive shaft . had the differential rebuilt recently and wheel bearings done about 8000 miles ago . Changed the tyres also and it's not as noisy now but you can still hear it . Question is , is that normal to have a rear end noise or what ?? PS nick named this C4 the money pit .
cheers

ok thanks i will order new rear wheel bearings and washers and hopefully eliminate the noise , cheers . Thing is that i thought it might be the bearings even though they have not done too many miles really , and there is no play in them either when i checked them . Thanks for the tip champ , cheers

The Teflon washer does not come with new wheel bearings...
You do not want to use cheap EBAY wheel bearings, go for Timken / SKF they are good brands that last.
Remember to torque the spindle nut to at least 164 foot pounds, it got revised even higher in service bulletins. You need a 36mm socket and a long pipe for leverage.
Good luck.

If you raise up the back I had play as my humming was caused by a right rear bearing that was in half if you have no play I don't believe the Teflon washer is at fault it is known for sgueaking. Even with my bad bearing that I have in my car does not make any noises or humming just a squeaking when I turn right but it has 1/8th inch play. I don't think your bearing are bad from your description if you don't have any play in them. Double check differential. The rebuild kits don't include the 2 bottles of additive it is possible they forgot to put it in unless you watched them as I did.

ok , cool thanks for that .Thing is that i got the diff specialist to put the new kit in , but i put it back in the car , he gave me the diff oil and friction modifier to put in it though . Funny thing is that after a couple of weeks i noticed an oil leak under the diff . The very bottom bolt that holds the diff to the batwing had snapped and that was enough to break the seal and let the oil out . Tried to drill a hole in the bolt but failed , so i drilled and tapped a hole either side of it and put new marine grade stainless steel bolts and washers in . A bit of sealer then put diff oil and friction modifier back in . I always thought that rear wheel bearings already had a spacer in them , or do you chuck that out and put this teflon spacer in , or what ?? and thanks again
