howdy all...
i have a bad vibration problem in fourth gear when power is applied and it seems to be worse uphill......im running a cj7 with 350sb.....nv4500....dana 300 the rest of the jeep is pretty much stock as far as lift axles tyres etc... it starts to shake at about 70kms but when u back of the accelerator it stops......it wont do it in third or fifth gear at the same speeds....ive checked tyres(balancing)steering alignment..and its all ok...the only thing i can think off is the driveshaft possibly ...has anyone come across this problem ? i hope its not my gearbox please help

I had a similar problem where I'd get a bad vibration at around 35 mph. Turned out to be a bad ujoint.
