Our '64 has an
8.75" sure grip differential. I have the car on jack stands and the drive
shaft removed. When I rotate the rear wheels I get almost instant movement
of the pinion flange, but when I rotate the pinion flange there is much
more "slack" before the wheels begin to turn. It seems to me that the
amount of "slack" should be the same regardless of which "end" I am
rotating. Is this behavior
normal for the sure grip rear-end, or do we have a problem?
I am trying to find
the source of a "clunk" in the driveline, when I shift out of neutral
into reverse or a forward gear. The "clunk" is kinda loud, and has a
sort of bell ring sound to it. The front U-joint is a bit lose, but
side-to-side not rotational, as though the ends of the "cross" were worn.
I will replace it anyway. Also sent the center support bearing
insulator to the Damper Doctor for rebuild. The rubber was intact,
but sagging due the car sitting idle for 12
years.
Any
advice?
Thanks.
