Hi,
I have just replaced the offside rear wheel bearings on my Sierra based Cabrio as i thought they had worn and were causing a noise. I was getting a noise from around 40mph. It was not a whine but more a wha, wha, wha, wha sound which increased in speed, with the speed of the car. Sadly have just got in from a test run and the noise is still there. Unless i have done the wrong side, i am at a loss as to what it could be. Has anyone else experienced this sort of noise from the rear of their Cabrio?
Any ideas or advice as to what could be causing the noise would be greatly appreciated.
Regards Mike.
