Hello,

I've been trying to isolate the source of the horrible creaking/rattling coming from (I think) the suspension on front end/driver's side, but i've had no luck and thought I'd ask here.

I hear this awful sound when coming to a stop, or making a right hand turn (weight shift to left during turn emphasizes problem I think). I can also feel some vibration through the floor under the dead pedal when this happens. No creaking when driving straight and no vibration in the steering wheel at all.

So far I've had upper control arm bushings and sway bar links replaced to no avail. Both were worn/torn. (80,000 miles)

Anyone have any ideas or experienced anything similar?

Also, its always worse in the afternoon than in the morning. May be heat related (AZ).

Thanks,

have the entire control arm(s) replaced because the ball joints are often loose by that time.
Consider there are also lower control arms with their own ball joints. Have them checked and consider replacing.

Sway bar links ok, but consider lubricating the swaybar bushings. You can squirt some aerosol grease in there (split bushing, find the split) or remove the bushings and grease them by hand with waterproof grease. If I went to the trouble of removing the bushings I'd likely drill and tap them for a zerk fitting.

you may want to have the wheel bearings checked out. Wheel hub and bearings come as one assembly on this car. I had a similar problem on my S5 and it turned out my front wheel bearings were shot.

to do so. I took my 2K4.2A6Q to a normally good Audi dealer and asked them to check the wheel bearings. No problem they said but noise persisted. I eventually put the car up on jack stands and let the wheels turn in gear. The bad bearing was easily detected when I walked around the car and the RF wheel bearing was lots noisier than the others.

BTW, it didn't FEEL bad, it didn't have a lot of play in it, etc., but replacing it (somewhere around 105K miles IIRC) solved the problem. It was just one bearing assembly as well. These are pretty good items and you just replace them as they fail which could be several hundred thousand miles!
