I have a XJR 95' Supercharge...Can anyone explain the harmonic balancer? There are two correct? One on top & bottom.
My car has been squealing on the start up? Can this be related to the harmonic balancers? I'm going to try the dielectric grease opposed to the belt dressing.

I've been trying to get to the bottom of the squealing problem..could it also be the aux fans?

Any help/suggestions greatly appreciated.
