well a while back i had a problem with the rear end of my car making a whooshing noise. come to find out out i a very low axle fluid which caused my axle seal to break and my bearing to warp my rear left axel. so i had to buy a new axel. after i got the car back from the shop everything was great...until i drove over some train tracks and noticed a thump/grind noise coming from the side which has the new axle, i thought it was the shocks so i changed them out. the ride is a lot smoother but i can still hear the grind which sounds like its in the rotor area and i also noticed a small ticking noise that only stuck around for a few seconds. if anyone can help me out with some suggestions id appreciate it.

 

have u checked the fluid level? could be in the brakes to how do they look? any oil on em? signs of heat?

 

How many miles have you put on the car since the new axle? Did the shop warranty their work? You could take it back for them to give a listen to.

 

If all the bearings weren't replaced, you might have a bad bearing.

 

everything seems fine with the brakes, i have 160,000 miles on the car and replaced the axle last month. both bearings and axle seals were replaced

 

No, differential bearings.

 

oh ok, i dont believe those were changed out. that would actually cause a clank noise at the rotors if i were to hit a rough patch of road?

 

Are you sure it's at the rotors? Are you sure your wheels are snugged up?

If it's more of a whirring/grinding noise, it's most likely in the differential...

 

yeah thats the exact noise its making... it kinda sounds like my wheel and brakes are gonna fall apart. i couldnt stand the sound no more so i took it back to the shop and wont hear anything til next tuesday. are differential bearing expensive?

 

Really want to know? They billed my Ext. Warranty $840.97: $390.97 in parts (3 seals, 5 bearings, 1 spacer, 1 gasket, and 2 lubricant), $450 labor (4.5 hrs)

The bearings were pitted...
