I have a '90 4runner. Every once in a while the clutch squeaks like a banshee when depressed. I had one shop tell me it was the result of a plastic bushing gone bad. I don't necessarily think so because the squeak seems to be coming from somewhere underneath the car and that year does not have the same bushing assembly as later models.
I had another shop said it was normal and could not be fixed. I don't think that is right either.
I also greased all the joints in the cab to no avail.
I also noticed it squeaks most after I take it to the car wash.
Any ideas?
