Any ideas what would be causing this clicking sound coming from my front passenger wheel? Wheel bearing?


It ONLY clicks when turning left.


Thanks for listening.

Are your hubs set to "auto"?

 

I tried the hubs in both positions. Clicks both ways.

 

That should rule out the u-joints in the knuckles. Bearings may be the next thing to check.

 

Either bearings or something with the ABS sensor or brakes is all I can come up with.


I would pull the tire and then the pads and have a look.


I would also pull the abs sensor and check it too.

 

Thank you both. I'll take a look.

 

Wheel bearings: Typically when a wheel bearing begins to fail it does so with 1 maybe 2 bearings. You can jack up your trucks wheel and spin it by hand and listen for a 'tick', this is the sound of one bearing hitting another, due to lack of grease.

Catch it early and its simple and cheap to fix or you can wait and make it expensive.

My wife had a MB, it was new with only a few thousand miles on it. I drove it and noticed the 'tick' in the right rear. I knew what it was, wheel bearing. I take it in to MB, they check it out and mech comes back with 'he cannot hear anything". BS I ramp it up and get the head Svc tech, he hears it but calls it normal, says there must be a piece of gravel stuck in tire treads. We go for a ride and yea sound is there but normal...BS I ramp it up and up finally I have GM of the dealership in the car, he hears it but does not know and sides with Mech, Svc Tech, Svc Mgr, crowd. I ask that they all sign off on my svc request (MB was in warranty). They do.

How SWEET it is: Couple of months later a loud grinding sound, car lurches to the right and grinds to a halt, I am driving. I call MB, they send wrecker we go to the dealer. While the mech is looking at it I knock on doors of the above. Mech comes out and talks to svc head tech, he calls Svc Mgr, and he calls GM.

GM walk over tells me to pick any MB for a loaner, no charge. He then asks me if I would interested in working for MB, he has an opening for a sr svc tech and svc mgr.

The repair cost a bundle, right rear wheel bearing froze up from heat and everything to include the axle assembly had to be replaced, where if they had just listened to me it would have been a wheel bearing and 1 hr of labor.

 

All the time - some times - low speed - any speed - changes sound at different times?

For me it was rust chips from the rotor that got behind the shield.
The ONLY way i solved it was by eventually changing the rotors.
There is no way to get the chips out without removing the rotor.

 

Duane, he says his is only when turning left. Did your rust chips make noise all the time, or just under certain conditions when moving?

 

There was no consistency to the noise. Sometimes I would not hear it for weeks. Sometimes only when backing out of the driveway etc. The first time I heard it I was concerned enough that I pulled up on a curb so I could crawl underneath the truck to check the driveshaft, thats how loud it was. Over time the noise changed constantly, with the the only constant being that once I got up over 10 MPH or so the noise went away.

 

My vote is with the wheel bearing. I've diagnosed 2 on my work trucks in the past couple of years. I think the reason they only sound off when turning is that the bearings are loaded differently during turns.

Used to be, we replaced bearings. Now they replace hub assemblies...

 

So I took the wheel off and cleaned everything with compressed air. I didn't see anything come out that looked like it was noise worthy, but the sound is gone. No signs of it and I was driving all day today. Hopefully it stays away.

On a side note, my engine warranty is up next month. I'm trying to decide if I should delete it or wait until another emissions related failure and then delete? She's been running awfully good lately after quite a few hiccups.
