    What brand clutch? I've had no issues since replacing mine with a South Bend four years (and one week, apparently) ago.

    i have been using a LUK from my local napa. i talked to a south bend rep the last time i had my clutch out. he said that he would love to sell me a clutch, but as long as im not tearing up the friction material, which i am not, a south bend clutch would not solve the center hub spring problem.

    i have a solid mass flywheel for a 6.2 that was new when i did the swap. this time i had the trans and t case rebuilt, new hydraulics, and im trying to replace everything while im in there so i dont have this problem a fifth time. i have the fork and pivot ball coming from the dealer, i guess now its a special order part its supposed to be here middle of next week.

    Actually, parts from my South Bend clutch were LUK components.

    I had swapped from the dual-mass flywheel to the solid flywheel when I replaced my clutch. I've seen pros and cons for each setup.

    i read through the thread again, you mentioned a "retainer spring" or plastic clip type thing in post 61. did that come with the new pivot ball from the dealership? or is that something i have to find separate? when i ordered the pivot ball, i asked about it and the parts guy said he thought he knew what i was talking about, but couldn't find it so it must come with the ball. he may be right, but he didn't sound very convincing, so i don't want to wait til next week to find out i still have another small part to find. if you got it somewhere else do you remember where you found it, or if it came from the stealership do you maybe still have the receipt with apart number?

    Had to go back through my pictures to see if I had one that showed the retainer clip. Here it is. I don't remember ordering anything separate, so I'm pretty sure that this came with the pivot ball. It screws/pushes onto the threaded end of the pivot ball.

    Thanks, I suppose I'll just have to hope the new pivot ball comes with it. At least now I have an idea what I'm looking for if it doesn't. Thanks again that helps alot.

    Its kind of interesting to hear your southbend was a repackaged luk, and then to see my standard napa clutch its a luk also. Although you have the kevlar option, right?

    I also wanted to ask, did you ever end up using that dampner deal that was discussed back when you were in there?

    At the time, I did not get the dampener. Afterwards, I happened to find one at a good price, but never got around to tearing it all back apart again. I really haven't noticed any vibrations or other odd characteristics without it.
