It always squeaked when the suspension moved but for some reason I could not duplicate it in the garage.
I have greased the Currie control arms numerous times - no change
I have replaced the rear sway bar bushings and greased - no change
I have removed, cleaned and greased, re-installed the rear track bar - no change
I have checked and rechecked the torque on the body mount bolts - no change
I have temporarily removed the belly skid - no change
I have temporarily removed the engine skid - no change
So last night I accidently hit the CB antenna and it squeaked against the spare tire........
Sometimes the little things get you..
