    Even though the title of this thread just BEGS for a joke, for once I will pass on the opportunity and let someone else take a shot at it.

    Your rear end just needs a bottle or 2 of stink juice (as we used to call it).

    Did it have additive in it before? It doesn’t sound like you need any more friction modifier.

    If you already have a friction modifier in the rear just go and find a big space. There, just run some eights. It helped in my Riv. I couldn't disengage LSD for more than 100 miles but eights did the job.

    Peace,

    How long has it been since the car was on the road? Sometimes the units will literally weld themselves together over long periods of down time 5-10 years etc.
    In this situation I would tear the unit out totally disassemble check all parts clean and reassemble and see if there is anything wrong physical inspection . IF a clutch did get truly welded to another clutch it could break a spider gear which you do not want.

    I had a '75 Electra with a 3.08 Posi, it was doing the same thing when it got warm, BANG BANG BANG turning a corner, only when towing my 24' Sea Ray, it was unerving:mad:
    I took the cover off, oil was full of metallic particles, and a couple clutch pieces in the bottom, don't know exactly what caused it, but I removed the carrier, and replaced the clutches, the gears seemed fine, reassembled, and all was well.

    The clutches were likely early style clutches which had big recessed cuts to move fluid through the clutches better BUT when you had the slip slip addtive issues the bang and hard releases and hooking shattered the daisy wheel clutches and then they fell out here and there and that made it even worse.
    NEW redesigned solid clutches will not do that.
    Or you can install carbon fiber or composite clutches too for a more quiet hook.
