Reverse chatter

I'm going to replace the rear main seal and have the flywheel resurfaced next week. Just a parts update. This is from Krage.

Here's the NAPA PN for the rear main seal off the 225:
rope: #SGARS742R
rubber: #SGARS742

Now do I buy rope or rubber?

 

I have a '71 cj and I have chatter problems. I know I have a leaking rear seal that I'll be addressing as soon as the parts arrive.
I was looking under the cross member tonight and discovered some interesting things. My '68 has a cable with a ball on one end and a threaded bolt on the other end. The ball fits into a steel fork welded to the cross member and the other end goes to a steel bracket ( 1/4" thick ) that attaches to one of the bellhousing bolts. The '71 dosen't have this cable and the cross member doesn't have the steel fork welded to it that holds the ball end. There isn't any evidence of there ever being one there.
Also I discover the transmission isn't bolted down to the motor mount! The motor mount is bolted to the cross member but there are no bolts from the mount to the trans!
I'll take some pictures tomorrow.
Does anyone have a parts manual blowup of the trans-mount-cross member area? I don't think I have the right trans mount.

 

Well, I just pulled my bell housing and I think I'm gonna rule out oil soaked as the issue. Dry as a bone. Lots of dust though. I think I need a cover for the clutch fork. Anyhow, I thought with the amount of oil on the front of the inspection plate that my rear main seal was toast, but after pulling stuff aprt I'm not so sure. The flywheel is bone dry on both sides, as is the inside of the inspection plate. I think it's just my oil pan gasket, as it doesn't seem to be coming up from anywhere higher. I did have a leak on the fron of the tranny but saw no evidence of that oil getting even past the adapter between the trans and bell. So, a couple of questions -

If my RMS was leaking would I see evidence inside the flywheel inspection plate?

Could a lot of dust cause the chatter?

The transfer case snubber is a big hunk of rubber hard bolted to the crossmember in one spot and bolted with a sleeve to another spot on the crossmember. It's in the blurry picture attached. Should I use something stiffer?

I've ordered a new tranny mount and plan on picking up motor mounts as well. Hope that does it. Any other insights appreciated.

 

Update:

Cleaned the pressure plate, flywheel and clutch with laquer thinner. It did appear there was some sort of contamination on there. I think it might have been from the grease I put on the shaft splines to try and make assembly easier. Sealed the leak on the front of the T14. New trans mount. Stiffened the x-fer mount a bit. Got a clutch fork boot.

After about 5 miles - smooth as silk - even in reverse

We'll see if it lasts - camping this weekend, so I'll get some opportunities to test it.
