Getting a vibration and some noise from the back end when braking, and sometimes when accelerating. I checked the brake system, and replaced any questionable components, so there shouldn't be any problem with them.

Sounds almost like a clunking, grabbing type noise with some vibration felt coming up through the seat. This symptom mainly occurs on braking, does not matter if I am in gear or coasting in neutral.

When acclerating, it sometimes feels like something is grabbing for a second or two until I am moving over 10-15MPH .

I have a '77 Spider with what should be the limited slip 4.56 rear. I changed out the oil in the diff, but no difference. Also looked like I didn't get the full 2.5-3.0 Pints out of the diff when I drained it, but cannot see any leaks. Am I looking at a bead bearing, or a fried limited slip assembly? Is it easier to rebuild or replace the entire axle?

Thanks.
