Well last week both my auxiliary belts gave up, I got two replacements and a guy from work fitted them. My problem is that a noise has developed after a couple of days. Under inspection I've noticed a slight wobble from the crank and idler pulleys. The car runs fine. What can I do to solve this? Any help will be greatly appreciated!

Sounds like the bearings are more than likely fcuked on the pulleys im sure some one else will advise you

How tight are the belts - if too tight the bearings will fail on the pulleys because they are getting over worked by the tightness from the belts. There needs to be a little slack on the belts when fitting. if they are too loose you will get a squealing noise as I noticed recently but has since been sorted.

They do feel a bit tight, I take it ill have to replace the bearings? Can I just loosen the belt slightly? Also can you buy bearings or would I have to replace whole components?

Try letting a bit of slack in the belts, it may sort it. Whip the plastic cover off and there's a 10mm head loosen that of a couple,of turns.

I've loosened the belt slightly but have noticed its mainly the idler pulley on the air con belt wobbling. Any ideas where I could get a replacement and how much?
