1999 Pontiac Bonneville Car makes a clicking noise when tur

Is the noise apparent going straight down the road? If yes, and it's only when turning, does it get more pronounced the sharper you turn? Is it only when you turn RT, and not LFT? Please advise.

I isn't appearant when you are going straight. It only makes the noise when turning right. It does seem like the sharper that I turn the louder the clicking noise is.

90 % of the time the cause of what you describe is a bad outboard Cv joint, BUT, it's usually noisy on both RT and LFT turns. You mentioned you had a 1/2 shaft replaced. Was this and outside joint and if so, which side. Also, what was happening that the joint was replaced?

The outstide CV boot had a hole in it and it was spitting grease. I thought this was the problem, but even thought I got the half shaft and the two boots replaced it still makes the same noise. The half shaft was replaced on the right side.

To clarify a point; When you say you had a 1/2 shaft replaced, do you mean the entire axle assm on the RT side, just the outboard joint, or just the boots? Let me know.

The half shaft was the whole assy. On the reciept is says NEW CV HALF SHAFT AXLE, EA. It was $60. Idk if this will help you or not.

OK, let's back up here just a little bit. What was the original problem that prompted the axle change? Was it the clicking noise?

No, there was a hole in the cv boot and it was spitting grease. I thought that it was going to fix the clicking noise too, but it still clicks only when I turn right.

I'm a little confused here. Did the shop change the actual outboard axle JOINT, or just the boot?

I got a new axle and both boots replaced. So now I have a new shaft and new boots on my car.

Is it possible it's the joint on the opposite side??

The sound is coming from the right side of the car. It does seem though that the noise does come from more in the front ride side of the car instead of right by the right side wheel.

OK, we're going to abandon any problem with a axle, so I need to ask a few questions;
Do you hear the noise when;
Turning right a highway speeds, just in town, or both?
More when turning sharply, during a gradual turn, or both?
Any noise at all when turning left?
Does it make a difference when the blower fan is running or not?
Looking inside the right fender well, do you see any sign of where the tire may be rubbing?

I have never heard it at highway speeds, but I do hear it when I am driving in town. It does make the noise when you turn gradualy, but it seems to make it a lot more whenever I turn sharply to the right. It only makes the noise when I turn right, not when I turn left. It doesn;t make a difference about the fan. And I looked inside the fender and It doesn't look like it is rubbing at all.

The only other thing I can think of is the backing plate on the right rotor is maybe touching the rotor just enough to make an audioable noise. Other than that, you've checked everything else.

Okay, How much distance should there be between the backing plate and the rotor?

It was making the clicking noise this morning when I was getting onto the interstate. The on ramp went to the right and the sound was reall bad.

Clearance between the rotor and the backing plate should be just a fraction of an inch "1/4" , even just enough so it doesn't touch.
Judging from your last post, you MUST have a wheel bearing going bad. If I'm correct, as you put on the miles, it will only get more pronounced.

A wheel bearing would cause a clicking noise? What are some other signs of the wheel bearing going bad?

A wheel bearing going bad will usually start as a clicking noise when you turn one way or the other. You won't notice any change in driveability. Then it will turn into a growling noise more pronounced when turning, but also when going straight.

Is there any other way to check and see if the wheel bearing is going bad? I lifted the front end of my car and turned the wheels and it wasn't making the noise. I didn't know if it would still make the noise if it was off the ground or not.

SOMETIMES, with the wheel off the ground you can shake the tire in and out and detect a little "slop" in a wheel bearing that is starting to wear. BUT, this isn't 100%. I wouldn't want you to rush right out and have a bearing changed that apears a little loose and still have the noise. The choice is yours.

Okay! Which changing the wheel bearing, does this affect the alignment at all. My alignment is off and I need to get that fix as soon as possible. I just wanted to know if I should try and get the wheel bearing fixed first or if I should go and get an alignment?

It "shouldn't" affect the alignment, but if you're going to have a bearing changed, I would do that before the alignment. In addition; in my shop to test for a bad bearing on the front of a GM. we used to lift one wheel at a time and with the engine running in drive, spin the lifted wheel under power. In doing this the wheel will actually twice as fast as it would going down the road. Using this process, we could listen to each side seperately. FOR OBVIOUS REASONS, this has to be done carefully. You don't want to be pulling the car back into the garage after it's gone through the back wall and is sitting in the backyard.
