Suspension? thunk sounds.

[stcroixdrew]

I have found a light thunk sound that comes to life while accelerating and shifting gears. I think it might be the shock towers moving.....but a friend mechanic said that the has zero movement and is very tight and sound. Any ideas out there? or similar experiences?

Sounds more like a loose swaybar...

That was my thought...but Im being told all looks and feels tight. Is there a way of checking that..or something to look for?

You didn't mention what year yours is but on my 2003, there was a similar sound on the drivers side. Under warranty the dealer replaced the upper strut mounts even though I said it sounded like a trailing link bushing... They were wrong and I was mostly right.

The reason I say mostly is that they ended up fixing it after I had traded it in on my 2006, I do know that the flat aluminum bar that can be found on each side just inboard of the wheel was bright and shiney new the next time I saw the car! (not sure what that suspension peice is called)

I had a thunking sound, particularly shifting from 1st to 2nd. It turned out to be a bad front motor mount. I fixed the motor mount, and the thunk is completely gone, and 1-2 shifts improved.

Thank you all for your input..I ordered a new motor mount for Sunrise Porsche for 183.00 and it was installed in 1.5 hours..piece of cake. And that made all the difference in the world...its like a new vehicle. Shifts better..perkier...just a real pleasure to drive again... Thank you again.
