The air con on my 300 TDI se disco has started to squeek, I think its the bearing on the compressors clutch mechanism, as it has a lot of play and all other bearings were replaced last year. Has any one got any info on changing this bearing?

Thanks Graham have asked Buckley Bros to quote for replacements.

has anybody had experience of replacing the hinge pins in the back door? If so what tools are required and where did you get the pins? Would it be easier/safer to replce the hinges?
