Odd "thunk thunk thunk" noise
Posted 21 September 2007 - 10:44 PM
There are no unusal sounds at low speed or sharp turning and the car feels normal driving. It kinda sounds like a con rod knock, but duller. It is not that, as I changed gear and the sound stayed the same, so it is not RPM dependant. It is not RPM or gear related and happens really above 60km/h and seems to go away at 100km/h, but that could just be because of wind/road noise.
Before I spend a whck of dough on diagnostic time at the dealer, anyone have an idea of where I could look to solve this myself?

also would check the strut mounts/nuts - after replacing struts on the other half's car he had one making an odd thunking noise - turned out the big nut (on the strut shaft) holding the top strut mounting plate was not quite tight enough - tightened that up and noise went away. (kind of a pain to do while on the car, but can be done!)
might also give a good checking to ball joints and tierod ends...

After replacing the ball joint I had it aligned, and they found everything in good order.
I think I'll try rotating the tires and see if that does anything, or maybe mounting the snows for a day and see if that changes it.
