C5 with rear end noise
Hi all
I just traded my old SS Camaro for a Red 98 C5 with Auto Trans I have not owned a Vette since 1966 and it was a 63 340 hp 4 speed. I drove the C5 home on Sat from Omaha, than went for a ride today and noticed a growling, grinding, or rumbling sound from the rear end. It is the same in N or in gear, coasting or in D in a straight line with no change when turing, The owner said the diff fulid was changed with Mobil 1. Any ideas? |
I'd call the previous owner and ask him/her where the car was serviced. If you do get this info, call to ask if there were any rear end issues with the car. How many miles are on the car?
|
It has 105,000 miles and I did talk to the orignal owner and the rear end
was changed with Mobil 1 75-90 at 96,000 they said it always had a little growl in the rear. I took it to a shop and the tech looked at the tires and showed me just the inside rib on the tread on all four was rough. He said to have them moved side to side and see if the sound went away. |
Huh!
Automatic!???

The diff does get 75-90 weight but I found this tidbit of info:
C6 owners may find that they have a chattering or popping during cornering. GM has a special fluid called Dexron LS fluid to combat this problem. This fluid is equipped with additional posi-traction clutch plate additives to smooth out those cornering chatters. This same LS fluid works on the C5 if chattering is experienced during cornering. |
I had the tires moved L to R but one rear was very chopped, but the tire shop had
a set of Goodyear run flats with 5,000 miles that the customer said were to rough riding. I bought both for $100. and now the rumbling is gone but I need to take it back for alignment after I replace the right out side tie rod end. Thanks |
