crankit

Been starting to get this shutter also most feels like the clutch but not quite there. Only does it when I take off easy. U joints feel tight but I remember once that I had a u joint freeze which caused problems. Funny thing is you didn't know it was froze until you pulled the driveshaft out. Anyone have them freeze up on them?

Sounds like a clutch slipping to me

Usually bad U joints make a ping or something when taking off and have serious vibrations at certain speeds or grate levels in the road...

By ping you mean metal on metal type? Also if I get on it taking off its fine.

When the u joints go bad sometimes when you take off you here a sound like someone taping the driveshaft with a bolt or nail. It goes PING

I do have that noise like someone hitting the drive shaft with a piece of metal but when I get under the car they feel tight, So is it possible its still them?

I also feel a roughness in the rear end around 45mph if that helps.

Sounds like a rear u joint, you tried pushing up and down on the driveshaft to see if it has play?

trans mount usually equals roar or vibartion sitting still in nuetral reving motor But suppose it could be seriously bad and cause that

Is it possible to be the carrier bearings? (rearend). I also hear a rumble back there too.
