Question about 2004 Saturn VUE
2004 saturn vue suv,while in drive with the foot on brake the drive shaft to the rear is turning and grinding in the rear.What is wrong?!
The RDM or Rear Differential Module on these GM vehicles (Vue, Torrent, Equinox) is a known weak point. It is most likely shot as the trans outputs power to the front and rear equally; gearotor pump(s) in the RDM then assign traction to each rear wheel if the wheel is turning slower than the input. So if it is still turning it must not be transmitting that torque to either "braked" rear wheel... There was a recall for the RDM in which GM quietly increased the slippage at which it engauged the rear wheels due to high failure rates...

If your drive shaft is turning, and neither of your rear axles are turning, the differential between these is probably the issue. It has gears in it, and maybe broken or teeth ground off.
