I have an 81 Westy which has approx. 1,000 miles on a new motor (which I
installed).  I took it on its first trip, approx. 500 miles, and it ran
great until I was coming home (the last 10 miles) and noticed this noise
coming from the rear end.  The noise is a clanking, clunking sound and seems
to get worse  when the vehicle is under stress i.e., going up a hill or
driveway.  Also, when I push the clutch in, the noise disappears.  When the
motor was out I put in a new slave cylinder and T/O bearing. I am totally
stumped as to where this sound is coming from........I hope it doesnt have
something to do with end play or the pressure plate.  I am not sure I have
the time or energy to drop the engine again!!!

Please, any help or suggestions will be greatly appreciated.

Thanks
Scott
