xiros® radial ball bearings consist of high-performance polymers, whereby stainless steel or glass balls move in the cage. Our radial ball bearings have been tested rigorously within our 41,000 ft.2 test laboratory to ensure long service life, even in coarse environments. Compared to metal bearings, polymer bearings have better wear rates and are corrosion-resistant, and therefore last longer in harsh environments. Their material properties are engineered to adapt to extreme temperatures or speeds, weight restrictions, or specific hygienic requirements, such as in food processing applications. Polymer radial deep groove ball bearings are also up to 40% more cost-effective and 60% lighter than comparable metal bearings. xiros® radial ball bearings are media-resistant, temperature-resistant, and self-lubricating, with no external lubrication required.

Any difference turning left/right/straight? So it always comes from the right front position, even after you swapped that tire to another location? It sort of sounds like you still have a wheel bearing problem. CV noises are usually more of a clicking sound at low speed that is much worse when turning. Sometimes inner CV’s can make weird noises, so that remains a possibility I guess. Inner CV problems are more rare than out CV problems though. What’s the model year & mileage? Same wheels and tire sizes as from the factory?

A visual inspection of the inner CV joint boot makes sense. Easy enough to do. If it has torn or split , at the minimum the boot has to be replaced, which requires removal of the half shaft.

Ballbearings

Types ofbearings and bearings

I could imagine you have a warped rotor that makes contact with the brake pads or a lazy caliper that does not retract after you apply the brakes.

The axle (technically called a “half shaft”) contains both an inner and outer CV joint. Is the sound louder turning one way than the other? If so, that’s an important clue.

One idea, squirt the brake disc w/water, see if that makes the noise temporarily diminish. Could provide a clue. Also ask the shop to check both the disk & wheel run-out with a dial indicator. The disc and wheel are supposed rotate in their own parallel planes without wobbling, and a run-out measurements tests for that. .

Also I started driving this morning and the sound only started after I took off after the car came to one (almost) complete stop.

Yes there does seem to be difference when taking left and right corners but it’s hard to make the sound go away entirely by turning left it just quiets down. Would replacing the Cv axle work or is the inner Cv a separate part?

So the bearing and Cv was replaced also but the sound continues. Could the knuckle be responsible? The previous owner hit a curb. 2003 137k.

Well, hmmm… with all the wheel bearing and both inner and outer cv joints you’ve replaced, and also eliminating the tires as a possibility by rotating, you got yourself a bit of a mystery groaning noise there OP. It could be the hub isn’t aligned with the rest of the car, and that is stressing the bearing. But that would show up w/a wheel alignment test, plus you’d be seeing weird wearing patterns on the tire tread. Have you had the front alignment checked? Noticed any weird tread wear problem? Like the tread is being scraped, or rubbed with sandpaper?

So, I have no idea what sort of tires were originally on the car. It currently has Toyo Synapse tires on it that are pretty worn but evenly so (I’d put them at 15-20% life). The sound started becoming noticeable after a 200 mile, rather mountainous trip.

This does sound like a CV joint. To further narrow this down, swap the tires front to rear and see if the sound moves. If it does, there something going on with the tires - likely irregular wear.

You said that your are STILL experiencing this problem. Does that mean you had all this work done because of this noise or were there other reasons for doing this?

Hello all, So I just had my tires rotated, wheels aligned and new wheel bearing installed and I am STILL experiencing an intermittent wuh-wuh-wuh rubbing groaning sound from the passenger front wheel area. The noise usually starts as soon as the car starts rolling and smooths out by the time I hit about 35. Could it be the Cv? It doesn’t change in frequency or intensity when the brakes are applied. Les Schwab said there were no clearance issues that they could see. Thanks! Edit: The cv and the bearing has been replaced. It’s not the tires. Apparently the brakes have some sorta high spot on them. Perhaps the caliper is also seizing. Brake job coming soon.

I’m starting to suspect the brakes. Last night I was coming home and I listened for the noise as I was coasting off an on-ramp. I dropped below 25, 20, 15 and didn’t really hear it. I rolled through that stop (no brakes at all (sorry!)) and made a point to fully stop at the next intersection. The noise was then very obvious. The front disks definitely look pretty worn and slightly notched. I also used an IR thermo. on the front disks and there wasn’t a significant difference but the passenger disk was slightly warmer none the less. I’ll squirt the disk next time I get a chance.
