I fitted new Timken bearings because there has been a constant rumbling from the rear.The rumbling has not improved. In fact I think it is even a tad worse than before.

What can I have done wrong?

[SecretSugar]

I did this with mine but at the front, turns out its my absorber...can you explain the rumbling, when it occurs and if it gets louder when turning etc?

has the drum ovaled??

[mrducati]

Thanks for your reply SecretSugar. It is a constant humming noise increasing in pitch and volume with speed, but is eventually drowned out by windnoise around 60 km/h. It is not depending in turning one or the other direction. Can't really describe the noise other than rumbling or the sound of a worn bearing.

Try your absorber. If you bounce your car up and down at the back, you should hear a little clicking like sound.

Hi,
I had exactly this problem a few years back on my 2005 Honda Civic SE. It was the nearside rear wheel.
I've also had something similar on an MG ZR.

I looked at the wheel bearing on both cars. In both cases the bearings were fine, and in both cases it turned out to be a tyre that was at fault. Visibly there was nothing to suggest anything was wrong with either tyre, but replacing them made the noise disappear!!

Might be worth trying your spare and taking it for a run...at least this will rule out the bearings/tyre/brakes!!

Cheers, Steve.

one thing to check is the back plate hasn't been dented , & is touching the drum

 

makes a loud rumble

What wheels are you using?

[mrducati]

Thanks for all your replys! Many good suggestions here for med to check out.  I doubt it is the dampers. I got new 3 months ago, and the noise is not dependent on bumps, acceleration, breaking or turns. Only speed seems to be the variable, and I can't see bad dampers beeing the cause.

 

has the drum ovaled??

 

If the drums are ovaled I would feel the breake pedal pulsating when breaking, would I not? It feels just fine.

A bendt backplate sounds plausible. Must check that out.

 

What wheels are you using?

 

The wheels I use are 13x7 in deep dish wheels, and I understand they are the worst when it comes to wheelbearing-wear.

Thanks for your tip Steve. Sounds strange, but if it was the case for you (twice!), it is absolutely worth checking out.

Check your tyres also.. some times the tyre can be damaged leading to a bump in the tyre tread this leads to a hum of differing pitches at different speeds..

 

Had this on my celica was caused by low suspension with low profile tyres.. with little shock absorption bumps in the road damaged the wire banding that holds the tyre together...

Excellent point!

 

I had the same problem with my Pajero - I was 100% convinced it was a wheel bearing problem...

 

A new set of rubber fixed it....

Youre gonna need a spacer at the back with most of these wheels, otherwise they'll rub on damers or even the radius arms.
