Gents. I have a 996TT from 2002 and have picked up a slight vibration on the left side of the car. The vibration occurs when i turn left. There is no vibration when turning right or straight. There is no significant vibration in the staring wheel, but tends more to be in the front of the car. The vibration is also audio and makes a constant rhythm. Is this the start of a wheel bearing breaking bad? And if so, is it left or right side?

 

Hard to say but why only change one, either do both fronts and be done or just do them all that way you know they are all good.
Besides by the time you get to the last one they get easier.

^ mine sound exactly the same. or a bit like a card hitting the spokes in the wheel of my schwinn sting ray.

 

Bad wheel bearing. The OEM bearings were cr@p. I replaced all of mine a couple of years ago. They were all shot. Change both sides on the front. If that doesn't fix it change both rears. They probably need to be replaced anyway.

 

Tnx for the advice. Then i will change both in front.
