The differences are that the open differential will have no clutch
discs in the center section where the limited slip unit does. Pages
below to look at the differences.
Figure 4. on the page below has both side by side.
Many thanks! According to these pictures, I haven't a limited slip.
All what I did was changing the oil of the diff. I added new 80W90 oil.
But on this day, the weather began to be very hot. I have the noise only
in hot weather. So I think that it is something else...
Does not sound like something I can attempt right now. How much for a
new and/or rebuilt differential.?? I hear signs of wear coming out of
it. Also.... On limited slip.... When changing the fluid, the book says
to add "limited slip fluid" with the 75w90 lube. Why is this necessary
and will it make the differential fail if not added. I think that is
what someone did.
But qould have the friction plates only when I have a limited slip
differential, right? So the noise must come from something else than
My differential looked exactly like the one on the right side of this
The only advice that I can give you is to open the rear end up again
and inspect everything for wear. This would include pulling out the
C-clips and then pulling the axles and inspecting the bearing
surfaces, not a hard job at all. It will take more time to put the
brakes back together than to inspect the axle bearings.
