Wheel Bearing Problems? Diagnose and Repair.

Hi!

I've recently been experiencing a knocking sound coming from the rear axle on the right side, and it just won't go away.

The wheel bearings are in good condition, have been tightened, and are not running hot.
The tires are also in good condition and have been swapped to the front.

The funny thing is, when I turn right, it disappears.


Any ideas?

I was recently a passenger in an Opel Astra, and I would have bet 100 euros that either a shock absorber or a wheel bearing was broken.

Good thing I didn't bet on it, it was just the exhaust system that was falling apart. It got stuck in such a way against the axle that all the vibrations were being transferred to the body.

Check if all the rubber straps are still intact.

Hi Gremlin!

Hey, there's no exhaust system here.
It sounds exactly like a faulty wheel bearing, but it's not.
It starts at 80 km/h, becomes extremely loud at 100 km/h to the point where it's almost impossible to have a conversation, and disappears again at 130 km/h.
Like a kind of imbalance.

I once had something similar with an old BMW. It was the tires, and the metal insert inside had been worn through.

It was incredibly dangerous; a small stone at 180 km/h could have caused a flat tire.

Hi,

There's quite a bit of evidence supporting Kenny's theory, as the rear tires on the C4 can last incredibly long – at least in terms of tread depth – while you simply can't keep up with replacing the front tires.

HI!

Alle 4? Nice shit.

@Markus
I can only agree with you on that .
I still remember my "tire-eating" statement.

The sound appeared out of nowhere, one second and then the next.

AUAAA, but it probably drives well .

The vehicle was NOT here for that reason.

This only became apparent under those specific conditions. The plan was for regular service.
According to the customer's own statement, they didn't notice anything .
