I will try to get a pic, but on my cougar(1986) there is a big rubbery thing twoards the front of my diff. When I accelerate, the back end picks up, not the front. Does this have something to do with it? Because, I have another 1986 with the same engine, and it dosent do it. It also dosent have the rubbery thing. I also decided that I have diffrent springs too. my other ones are alot softer.

Rubbery? Or a big cast-iron dog bone mounted with rubber and big bolts? That would be a vibration damper to smooth out the rear end. Our Cats & Birds are luxury cars, you know.

Or perhaps you mean a "pinion snubber"? Looks like a rubber cone, presses against a pad under the rear floor when the suspension is near bottoming out. Helps keep the rear end from twisting.

Are you talking about the axle housing "rotating" when you accelerate? When you accelerate the front part of the differential is supposed to come up. The rubber snubber is there to stop the diff from rotating too far. The differential will try to rotate in the opposite direction than the wheels.

The back end is supposed to pick up on acceleration. It's called anti-squat, & it helps plant the back tires.
