It makes the noise when the car is first started in the morning, and appears to disappear once the pulley is warm, about 5 mins of driving.

The aircon works all fine and cuts in an out as it should.

Has anyone pulled the pulley off the air con compressor? Is there even a bearing in there?, or could it be lack of refrigerant?

The bearings on the pulley are fully replaceable - and you only need a standard puller to remove the old one, they are standard bearings a any good bearing place should have them, unless of course you have an OEX/Ingram or Repco store nearby - they will definately have them.

Unlikely to be lack of refrigerant

if it's a D1 or 300tdi defender, I believe karcraft (sydney) have replacement pulleys w/bearings

I have just found alot of info in the technical section - why didn't I search there - I always forget!

Thanks guys.
