You guys are way out there. :no:

Only Terry was even close.

Once you get 3 to 400 posts under your belt you'd know that it's a classic symptom of bad Muffler Bearings. :yes:

:censored:  amateurs. lol

" NOTE",  When replacing Bad Muffler Bearings, Be sure to use BALL bearings. IT is all ways best to have ball bearings under your belt. Not Roller
Bearings, :yikes: IMHO  Jerry

Strange, my CAD-A-RAM does that to, but when I get on the gas. I'm blaming mine on the F#&d driveshaft I used. It has a slip yoke on it that has just a tad of slack in it.

While I don't have a muffler bearing handy, I do have a pic of my muffler bearing support. Yes it is mounted to a stand because they are so rare. Mine is sitting on the mantal above the fire place.

:eyepopping: OK, now I'm confused. Is the picture flipped or is it really a left handed muffler bearing
support??? Never saw one backwards like that. :scratchchin: :scratchchin: :scratchchin:

I think the pic was taken in a mirror- it's the only safe way.You don't want to look directly at 'em. :yikes:

I got a box full of new and used dempsequters left over from previous projects. If you guys think there's a market for them  I'll put them in a for sale post.

This thread really got me thinking so I looked way back in my chemical locker & found an original can of Reletive Bearing grease that I believe was the prefered lube for the muffler bearing (at least the high speed ones). :scratchchin:
Also found a tube of weinerslide & a jar of acumpuckie. :eyepopping: Dangerous, but good to have around. :screwy:
:bs: lol :bs: lol
