Hi y'all,

I heard occasional knocking sound that comes from the front part of my 2000 s4. At first I was afraid coz I might have dropped something into the engine moving parts... However, it might also be the engine is having a problem. Has anyone encounter this before?

Another problem is when I'm braking, my car seems to shake. I thought at first it must be a warping rotor. However, I've just changed the front rotors and brake pads. Shaking seems to persist, on speed 80mph and while braking from 50mph to 0. I'm going to try to change my tires and align my wheels... Any thoughts?

Thanks in advance!

Wrong wheels bolts and/or loose wheel bolts.

tightened with hands, no compressor. Im pretty sure it's tight...

RKA

Both. Do you have aftermarket wheels?

rest are worn on the outside because of under inflation (i think). But I always make sure every week to put 36/34 psi on my tires...

Re-bed? They are new brake pads and rotors

Take a good look at the front suspension. You're looking for a loose bolt somewhere. Odds are that will account for both of your problems.

should I just buy 18" wheels

Knocking and shaking is not due to a bad alignment.
