Last week I noticed a noise from the right rear as I was pulling up to a stop sign.

Last weekend I jacked up the rear and tried to replicate the noise, but couldn't.

On Monday, I discovered that the noise only occurs when the car is hot (after running for approximately ten minutes).

The noise is fairly soft, and is drowned out by road noise above 15 MPH. The noise occurs each time the wheel revolves. At 5MPH, the noise sounds like the brake rotor might have an irregularity that is catching on the brake pad each time around. However, any time I've ever had a brake issue, the amount of brake pressure on the pedal affects the noise. In this case, the brake pedal does not affect the noise (except that the brake pedal affects the speed of the vehicle and the frequency of the noise).

At 1MPH, the noise occurs as four distinct KINK sounds. As the speed increases to 3MPH or so, they blend to one continuous GRONK noise.

I took the car in to a mechanic on Tuesday. They said I had a hot spot on the rotors, that turning them would not fix it. So, I ordered new rotors on Wednesday (from Hardtopguy) and they arrived today.

I installed the new rotors this afternoon (BOTH of them https://www.s2ki.com/forums/index.php?showtopic=690729), and guess what??? IT'S STILL MAKING THE NOISE!

So, what are the other likely culprits? The mechanic said the wheel bearings were quiet. I wonder if they listened to me and got the car warmed up first.

CV joint, perhaps?

Differential?

Any thoughts or ideas on how to diagnose?

Thanks!!!

 

sounds like either CV boot or wheel bearing.

 

My money is on the axles.

 

So, how should I go about diagnosing the problem:

1. Wait until it gets worse so that I can hear it any time?

2. Replace the axle with a good axle from a part-out?

3. Replace the wheel bearings?

4. Replace the axle and wheel bearings at the same time?

 

Ew I love this game lol... Its your wheel bearing. It happened on mine at the exact same speeds and it was actually the right rear as well. It sounds like a metal on metal grinding sound and it starts around 5-15mph. Ma boys @ Napa did the job for 260 and that was with an OEM bearing, and it took 2 hours I believe. Get that thing done fast though, if you wait too long the bearing will eventually get so hot that itll be a royal pita for the shop to push it out. Hope that helped

 

Thanks!

 

Sounds like a bent brake heatshield/splashguard rubbing on the brakes. Check that they are not touching anywhere by just bending them back.

 

Sounds like a lot of things...but I'd bet on a bad wheel bearing, too. I had one go bad. Didn't sound at all like a wheel bearing to me but that's what it turned out to be. Symptoms were just as described...including an inability to reproduce the sound with the car on jack stands. Dealer replaced the bad bearing (and the hub, because a new bearing wouldn't press into the old hub properly...obviously a defect.) All was covered under the Honda Certified warranty.

And, btw, oddly enough, it was ALSO the right rear.

 

wheel bearing. there are lots of threads on this recently, a 5 minute search will probably show that all of the TS have similar symptoms as you.

 

If its the wheel bearing you'll hear it more so when you making a right hand turn, due to the fact you have the weight of the vehicle on the bearing. and when you turn left the noise should clear up some, not necessarily go away!.... find you and empty parking lot and do some figure eights! FIND THE PROBLEM don't go replacing parts you don't need to! if it ain't broke don't fix it, or something like that
