Rear wheel rattle on motoway?

[v896]

Anyone help please

Ok was bombing down the M1 when my GTI began to rattle on the rear wheel at high speed is this a common problem? not sure what could be wheel balancing? only happens when driving past 80mph any ideas would be much appreciated

yeah, my guess would be a wheel balance has come off. Also check your nuts are tight...

. Wheel balancing doesn't affect the rear. Plus you saying it's a rattle so check the suspension nuts/bolts
