My '83 GT has a Turbo Coupe 8.8 in it, and it's grinding. It only grinds when making a turn, and only after the car has been driven for awhile. All the info I can find suggests that thelube is worn out/too thin, and that seems to be the case. When I drained it, it was quite thin looking. I cleaned out the housing, and refilled it with 80/85/90W lube, but I can't drive it to test it out, because the car is on non-op (California.)
I just wondered if anyone else knows of another thing that would cause this?
Also, I have about 1/8" end play on both axles. That seems excessive to me, but everybody, even the Ford mechanic, says that's the nature of the beast. These are not pressed on bearings, it's a C-clip rear end. I was wondering if there's any way to adjust the end play, like a thicker C-clip?
