Driveline pulse

Howdy from Canada.
I've got a 1995 YJ, 4.0L, manual 5 speed, 90,000 miles on it.
I've replaced the rear driveshaft U-joints and tranny mount/vibration dampener yet I still have a pulsing in first gear under hard acceleration and has spread to second gear. This pulsing only occurs in 2 wheel drive.
Anyone know what the problem could be???

The pulse is speed related... In first and second gear, the harder and faster the jeep accelerates the pulse increases and is quite pronounced, sort of feels like driving over those indentations on the side of the road to waken sleepy drivers as they leave the road.
The clutch is excellent.
