worn crank pulley bearings... maybe

hey guys

Im having quite a noticeable moaning/rubbing noise coming from my pulleys. The belt is pretty tight so no issues with loose belt.

its only started happening the last couple of days as the weathers got colder, if thats got anything to do with it, but it sounds like its coming from the (looking at the engine) right side pulley, the one with the gaps in the middle.

is this the crank pulley ? iv read alot of people on here have had the pulley brake on them.

can anybody describe the issues they had before their pulley went?

any help would be a massive bonus as i'd rather not be driving and hear a bang

p.s. i now know there are no bearings in the crank puley :-)

There are no bearings in the crank pulley, and its the one at the bottom. Sounds like you may be referring to the PAS or Aircon pump pulleys.

A pic would confirm and help lots

ahh i see , it gets louder when i turn the wheel full lock or just before full lock,

Does this mean my PAS pump maybe on its way out ? how much are we looking at for a new one ?

It could simply be a noisy belt due to temperature and humidity changes, my auxiliary belt used to get noisy under these conditions, try a light spray with WD40.

Otherwise by what you describe it could be the PAS pump showing signs of wear.

Cheers for the advice guys, will be doing all fluid changes on sunday.

so will bleed the system proper and then replace belt and go from there, although i did just top up the fluid and started the engine and the noise had dyed down alot.

might just need a good bleed out on another note, can anybody tell me why it makes noises when there isnt enough fluid in the reservoir. would be good to know for future reference.
