 :-kMy 200TDI Disco has a strange rattle I am having trouble pinning down. Engine cold, clattering noise n/s of engine. Removed alternator belt and clattering stops. The alternator is nearly new and makes no noise or has any sign of wear when you spin the shaft with the belt off. Also the noise is hardly noticeable when the engine is warm. Could the extra load of the alternator belt be causing the power steering pump to be noisy. :-k I know the TDI is a bit rattly but this is above the normal.

Range Rover Blues:
It's possible that the tension for ther alternator belt pushes the PAS front bearing away, or put another way the PAS belt and alt belt pull equally hard in either direction :-k

The poor old girl has been pounding the lengh of the M62 since January and its only now I have stood still  for a while I noticed this problem. A new pump at £150 is a painful way of testing by substution, I mite buy a second hand one to try it. My 90 had a noisy pump after drinking Kirton pond water but that was cavitation. That was easy to tell it stopped working the day I sold the truck :oops:. Hopefully I can get it into work tonite and have a susing and bogling session on it. :-k

Banjo:
Has it got a cover on the back of the alternator, had trouble with that on mine , made a real strange bearing like noise.

bigwood:
 :huh: The saga continues, one power steering pump (cheap second hand one) and it still rattles. One thing I have noticed is it is noisier if I only move the vehicle a short distance. At work I usually have to move it fifty yards to the main car park. At the end of shift it rattles quite badly. :-k Could this be linked to the problem, maybe the alternator working harder when charging is in some way connected. :undecided:
