Having just got the trusty 124 through its last MOT and shod it with 4 brand new Tyres It has suddenly developed a knocking / tumbling type noise from the rear O/S wheel The noise only appears when coasting to a standstill

it dissapears under acceleration or even gentle throttle opening

it cant be heard under braking

cornering doesnt seem to affect it

It does seem wheel and speed related in that it speeds up if coasting down a hill

The rear Bearing on that side was replaced last summer so hope its not that

It seems coincidental that I've just had the tyres replaced when they were removing the wheels the car was in Drive not Handbraked and therefore the wrenches were rockling the car back and fro on the drivetrain as they undid the wheel bolts. As soon as i saw this I applied the handbrake . I have the feeling that the noise and the tyre fitting is related but cant make sense of the symptoms.

I can now answer my own post !

I have just gone to remove the roadwheel to inspect the brake parts inside the drum and lo and behold the wheelnuts were not very tight!
They were tight enough for the wheel not to wobble when i pulled and tugged it to check the tightness ( firstcheck i did ) but obviously when driving thres a lot more force at play so tightened up and now .....no noise!

always double check the obvious band never assume anything!
