You need to rebuily the cluck pack in the rear end. Ive been rolling on one tire fire for some time now. Im just gonna wait till I have the money to totally build the rear. But didn't you just get you 4.30's in. Who installed the gear anyways.

I have been looking in to rebuilding my rear end also. Summit does have a bearing and seals kit for about $80. But this does not include clutch packs. Those are about $50. I believe you could just replace those, but I'm getting everything replaced except the differential itself. Gonna cost over $500 with new gears, bearings, seals, clutch pack, and labor. Oh well, I want it done right.

My old man got my clutch packs at Ford for 40-some dollars. He rebuilt the posi and installed 3.73's in a little less than three hours. I haven't had any problems since.

If you can come up w/ the money then get an Eaton or Auburn.

ok tell me what you think about this: i can roll to almost a dead stop, pin the gas pedal and take off and have it not hit posi all the time. but from a dead stop when i revv it up an dump the clutch it hits posi fine. does this make any sense? is this normal?

You can't judge it from a roll, you could have good tires that bite, or you could have a nice tacky surface. Go from a dead stop, rev it to 5k and dump the clutch. Ask someone to stand behind you and see if both tires are spinning.

dont worry about it then ... listen to what joe said.. it could be various things on the ground etc... only way is to find a clean road and from a dead stop rev to about 4k or so... then dump it.
