On the I-shaft near the firewall, you'll see the rubber isolator and rivet strap assembly. That assembly has a plastic anti-squeek clip that goes around the I-shaft tube. There were 2 designs, 1 has plastic teeth the other (older style) doesn't. Either way, spray that plastic clip with your favorite type of lube concentrating on the clip to tube interface. Hopefully that helps... If not, you'll need a bigger amp :-laf
