Engine/Drivetrain Vibration Issues

[jondee86]

It seems to me that there are three separate and unrelated (in my
opinion) problems here.

1. The "clunking" from the rear differential. The CW&P will not clunk
if the backlash is set correctly, so the sound most likely relates to the
movement of the "ramps" as the LSD moves from the power-on to the
power-off position. Check with people who know about your LSD.

2. Bearing clearances in the engine. These have no affect on the
rotational inertia or power output of the engine, so are most unlikely
to have any affect elsewhere in the drive train.

3. A "rattling" sound or "vibration" while decelerating. Here it would
be useful to define if it is one or the other. For "rattling" I understand a
loud metallic sound, mainly heard rather than felt. For "vibration" a much
softer noise, and movement easily felt from anywhere inside the car.

I am making two posts here as my PC is crashing, and I lost the last
one
