I have a 1999 4Runner SR5 4x4 5 speed. It has developed an annoying eeerrt eert kind of squak at slow speeds. I rock the truck side to side and there is it. I get under it and lube everyting in sight. bushings etc I mean everything and it is still there. It is driving me crazy! No worn bushings etc... Everything looks good. I have not been off road or in water with this thing. Anyone have a similiar experience? If so what was the fix? Thanks.
