Most of those that have had the TSB performed have had the misfortune of the wheel clicking coming back, sometimes in spades, (where's AERO1 at?). Wishing you luck, but more than likely it will be back.

Just dropped my V off for the clicking noise. Service manager states it is the front wheel bearing. Has ordered new bearing and should be installed by Saturday. Will post if this corrects the problem. I saw an earlier post questioning wheel bearing tolerance, but nothing after. Any more updates regarding wheel bearings???

Mine just started today (after I let my father borrow my car)

I suspect that multiple full-lock turns at around 2 to 3 mph triggered it from what he said. I rarely do a full lock when turning based on a mechanic years ago that told me that that pitch change that the pump makes is the pressure that causes leaks. My point is that if you have a newer V and want to prolong this until a positive repair is reached, avoid full-lock turning if possible.

I will watch here for results from others.

No biggie for me, still the coolest dam car, and I have confidence in the service it will get.

How many miles on the car?

Mine has 3000 miles. Started clicking three days ago. Took it in to the dealer, and they said there was nothing useful they could do now. Said GM was engineering a fix. I asked them if there was any risk at driving it, they said no. Of course I do not know how they know that, if they do not know what the problem is. I mean if it is the bearing, then something bad could happen. Anyway, I was thinking of going for a three day joy ride in the remote west, to do some really high speed driving but now I am concerned about going 150+mph when I do not know if the bearing is the problem.

I will be checking back with the forum and dealer periodically to see if a clear fix has been found.

Hi guys I have an 09 with 3500 miles and I noticed mine clicking the other day and like most of you it only does it at full wheel lock left or right . Please keep me in the loop if a fix is discovered for this .
Thanks

Mine does not have to be anywhere near full lock. 270 degree turn of the steering wheel to the left is enough for lots of loud popping from the right front wheel. Only the right wheel does it so far. Sounds like someone hitting two spoons together. Really embarrasing as I wind my way through the parking garage at work. Someone walked up to me today after I parked asking if I was aware that something was broken.

Anyway tonight I jacked it up. Wheel seems to rotate as expected with nothing unusual. No unusual play in the assembly either. This whole thing is really strange.

Mine does it too, gradual onset as the weight increases on the wheel. The more I turn the wheel the more it clicks, I believe this has something to do with the weight of the vehicle and the hub bearings which is why I asked about bearing tolerances. Some ball bearings are soft enough to absorb small particles, maybe these are too soft and are wearing prematurely. I wonder if the supplier cut corners on manufacturing them (chinese?).

I think that stuff a mechanic told you years ago about full lock turns is null and void nowadays, at least on our cars - like when you could only put the car in overdrive after you were traveling fast enough.

Maybe just a dumb question, but has anybody themselves had either of their *front wheel* hubs off and inspected the wheel bearings. Is the wheel hub and the bearing a one piece design? If Gm were to have to replace a front wheel bearing, would they be able to replace only the bearing or would they have to replace both the hub and the bearing?

I have had this dreaded wheel clicking issue since the car was new with very low miles and after each time the dealer performed the TSB, the problem always came back within 1,500 miles. GM is sending two lead field engineers to my dealer in a week or so to check my car out. The dealer is also getting two new front rotors and hub assemblies in case the engineers want to install them if they feel that is causing the wheel clicking issue. I think my car has been at the dealer at least 5-7 or more times for this clicking issue.

I am also experiencing wind noise from the right side of the car. It sounds like it is coming from the B-pillar area. The B-pillar trim piece above the seat belt mount where it meets the headliner is not flush like on the driver's side. There is a gap there and I can't believe the factory let the car go out like that without making sure there was no gap and they should have made sure the interior pieces were flush and fit perfectly. I think that is where the wind noise is coming in from. Sometimes it sounds like the window is cracked open. That's how loud the wind and exterior noise is and the faster you go, the louder the wind noise.

SG:
From your post I take it that the bearings are an integral component of the hubs? Is that for rear as well as for the front hubs?

Aero1: I have the same wind noise and weatherstripping fit problem on my car.

Very interested to hear what the field engineers say. Tell them many people have the wheel clicking problem.

I thought GM engineering was working on a fix already. The fact that they are going to the dealer to see what is wrong with yours tells me they are in the early stages of diagnosing/fixing this problem.

Gary Wells,

Honestly, I have no idea, but I will let you know as soon as my car gets checked out by the GM field engineers.

another_lap,

The weatherstripping fitment is not where I noticed the gap. I noticed the gap on the inside of the car located on the B-pillar. There is a gap where the seat belt mount cover meets the headliner. There is a gap there, but I can't tell if the wind noise is coming in from the area where the gap is. I will report it to GM when my car goes in and hope the field engineers can solve the problems my car is having.

I would also say that GM isn't anywhere near close to resolving the clicking noise and they are aware that a lot of CTS-Vs have the problem. Who knows when they will have a fix for the car.
