Hi everyone.
After spending a year chasing a cyclic vibration noise in my '77 Aspen (5.2 magnum/a904) in the 1800-2000 rpm area, I discovered the problem was a little dent in the power steering pump pulley. Replaced pump pulley and crank pulley and the Aspen was smooth again.
Hoping to get rid of a slight driveline vibration in 35-45 mph and 75 mph++, I replaced U-joints and transmission mount on it yesterday.
The vibration issue is gone, but now I hear a mid range rpm noise through the floor. I'm sure the cheap (Westar) trans mount from Rockauto is the source of my problem. Engine running strong and smooth, no misfiring.
Googled the problem and found several Jeep forums stating aftermarket trans mount is crap with rubber being too hard, and OEM is the only way to go.
Comfort is my goal here, so I prefer rubber mounts and not poly.
Has any of you guys or girls any experience with this? What brand should I buy?
