Hello

Anyone know what could be causing this.

Loud knocking noise from under rear passenger offside. Several scenarios when this happens.

Was barely moving in traffic then loud banging noise from rear underneath, no noise when engine just running, banging seems to become quicker faster you move forward, In reverse sounded like a grinding sound, seemed to be restriction in movement of vehicle forward and reverse, Sounds like something stuck/trapped on wheel and banging as rotates.

After having turned vehicle off for an hour noise gone and ok forward and reverse, had initially been driving for 30 minutes before problem happened. Have heard whining like noises recently from car

Scenario 2
Drive over 50 mph and get that loud banging noise eventually.

Scenario 3
Every know and then that sudden banging noise and then goes quickly.

Is it the rear differential ?

Vehicle.
