Question about Cars & Trucks
Need to check it out underneath. Loose or missing exhaust hangers can let exhaust system rattle. Grab and shake looking for loose components including driveshaft and shocks.

A drive shaft that has lost a balancing weight will vibrate between 40 and 50 mph. If not corrected this could damage the input shaft bearing and seal on the differential causing oil leakage. Differentials are fairly indestructible but if run without oil will fail.
As for the front end you should never run the 4wd on dry pavement. The front differential is a posi traction unit that will turn both wheels at the same rate unlike the rear diff that will allow the inner wheel to turn slower than the outer on turns.

check the drive line play at the output of the transfer case to the rear universal joint.the gears are known for that.

Increased vibration from a vehicle indicates worn out engine supports. This vibration often disappears when revving the engine high, but is very noticeable at low revs.
You can have these inspected and possibly replaced to reduce the vibration cominf from your engine.
Hope this helps.

SOURCE: 2004 saturn vue awd HELP!!
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...

The fluid in the versa trak AWD in the rear is old and needs to be drained and refilled. After you drain and refill it, make a bunch of sharp left and right hand turns, then drive it for 10 minutes. Drain and refill it for the second time and problem solved. Use only versa trak fluid available at any GM dealership.
