    it'd help us if you could describe what it is doing or not doing...

    Clutch chatter and slipping are fairly obvious signs you have a problem.

    All you are feeling is the clutch chattering which can be cause by oil on the clutch disc, warped pressure plate, clutch not fully releasing, and many others. If not to bad just live with it. If to bad full the tranny to check the flywheel or replace the clutch. Some times just adjusting the linkage can solve the problem.

    get under your rig and pull/push on the driveshaft near the ujoints and see if there's excessive play. i would lean VERY heavily in the direction of a bad ujoint... i've been there: [​IMG] your description matches mine just before i checked this. :D this is pretty extreme tho and was due to some other issues you aren't likely to have. this is the joint which attatches to my 205. don't know if you've got a 205 or a 208 - so check both if you've got a 205, or the one at the pinion yoke w/ a 208.

    don't know if my last post made sense. looks like you've got an sm465/205 set up. there are ujoints which connect the driveshaft to both the tcase and pinion yoke. check those. :)

    different u-joint. i'm talking about the one on the driveshaft that goes from the transfer case to the rear axle. there's one on either end of the driveshaft. check those.

    i'm sure your driveshaft is fine - but i really doubt your u-joints are.

    Clutch chatter is usually caused by oil on the clutch disc...do you have any leaks at the rear of the motor?

    Yeah, that'd be the problem then. I just did this on my 6.2 and have had to do it to my old 350 too. Both clutches chattered, although the 6.2 clutch would smooth out the more you used it.

    To really fix the problem you'll obviously need to repair the rear main seal, then have the flywheel resurfaced, new clutch disc and pressure plate.

    Drop tranny and T-case, remove clutch and pressure plate from flywheel, remove flywheel, remove oil pan, unbolt the rear main bearing cap. The rear main seal halves seat in the rear of the block and the rear main cap. I use a small wooden dowel to push out the old seal half from the block, the half in the rear main cap you can just pull out.

    Push the new seal half into the groove in the block, install the other new seal half in the cap and bolt it back up.

    A Chilton's will have some pic's and a better description.

    Basically a buttload of work for a $25 part...
