[ROVERNET - UK] Re: riddle me this-sudden 3500s road noise

Hello Peter,

Road noise would suggest a problem with tyres.  Sometimes balance weights
fall off causing such immediate symptoms, especially if you hit a pot hole.
 A close inspection of the wheels may reveal where a weight has been lost.
 Why not do both balance and alignment because the latter will also reveal
any excessive movement in the suspensions ball joints or wheel bearings.
 The former will reveal whether a tyre has gone out of round.  With the car
on the hoist, why not check the rear bearings and the universals as other
roverneters have suggested.  

Lets us know how it goes
