Thumping noise

[Albrechtk]

So, between the speeds of roughly 20-55 i get a thumping sound from the passenger side of my 2008 H3 base when in a right hand curve, not to the left, when turning or when going straight, it's not the front calipers, I replaced them. Any Ideas?

A chevy dealership claims it's 3 things
1) left front wheel bearing
2) right front axle shaft
3) front diff
Not sure I believe the diff, the other 2 I can see, so the parts aren't too bad, how hard is this labor? I still owe just over 8,000. On it, and I love it.

It could be diff mounts, steering rack mounts, suspension bushings, loose shock, numerous things. Can you add any more detail? No thumping over bumps, when braking?

 

[Albrechtk]

Nothing unusual over bumps, doesn't make any extra sounds when braking. The boot is torn on the passenger side axle, and I saw him grab the drivers front tire while it was on a lift, and he shook the hell out of it. I only doubt the diff because I told him it was a fear of mine. I had a truck that the rear diff went out on it.

Single thump or constant? Right turn means all the weight is being transferred to the drivers side so it sounds like suspension related. Could be bad ball joints or bushings if it's a single thump.

 

[Albrechtk]

Not really constant, but repetative

 

[rascole]

Bushings and ball joints are wear items that need to be replaced periodically. None of which are hard or expensive to do. Doing them all at once can be $$ but will be cheaper in the long run as you only have to have it on jack stands once.
