Hi listers.
I wonder if I could get some insight/advice on a knocking noise that seems to
be coming from the RH side of my rear end. I notice it more @ once I get up to
about 50 km/hr, especially over bumps (to the point I thought it was the shock
absorber and replaced that to see if it
Is this a single or erratic knock, or a continuous knock-knock-knock-knock?
Here is one way to test those U-joints:
Put the car in neutral and cost at about 25 MPG. Do some reasonably quick
S-turns,

If you have a driveshaft problem, such as a bad U-Joint, it will often show

an obvious nasty vibration round 50 MPH.
With respect to your knock if it is irregular and happens over bumps etc.,
it could be from anything that moves with or comes in contact with the
suspension. If it is
Don't forget to check that all the nuts and bolts that hold the three
U-joint flanges to the differential are tight!
