Shifts fine Driveshaft spins jeep wont move
Got an 88 4.2, ba10 stock except for 3in body lift, 32x12.5s.
While back was at a stop sign to turn right. took off pretty hard moved like 10ft and heard/felt loud bang. Similar in feel/noise to taking with a bad tranny mount except louder. I get back on the gas and it does it like 2 more times and then everything fine once i got up in speed. 1/4 mile later it does it again while driving staedy at 35mph. just one loud bang, jerk of the jeep, then went along fine. Then everytime i wood stop and get going, it would bang and randomly down the road going straight. then i noitced it would do it on right turns and up my steepish driveway. went up and down driveway a few times to try to pinpoint the noise better... anyway eventually car wouldnt move anymore. shifted fine but as soon as the clutch would grab in any gear and power was applied all id get was banging. It sounded as if it was coming from the transfer case or rear of trans. So i pulled the transmission and TC, rebuilt the tc, new clutch, rear main seal, new crank pilot bearing. even though they all seemed fine. Put all back together.
Anyway, jeep still not moving. what i missed before is that when in gear the driveshaft is spinning. jeep just not moving. banging is mosltly gone now. Basically I can put it in gear, let off the clutch with no gas, jeep doesnt stall, and driveshaft will spin but the jeep just sits there. One thing is that in reverse like 1 try in 20, if work the gas/clutch very slow, something will catch It will bang but reverse will work for little while, though banging most of the time.
im guessing now that the rear is bad in some way??? I have no experience at all with the rear. Havent had a chance to pull the cover yet.
What does it sound like it could be? ThanX
