Truck jumping when accelerating from a stop

[CliftonRover]

hi, I have developed a problem with my 88, when I accelerate from a stand still, ie any time I use 1st or 2nd gear, the truck bucks a lot. It is not because I am learning to drive it, this is a somewhat recent problem. I am wondering if it is oil on the clutch or if my tranny is finally shot. there does seem to be a good amount of play between the engine and wheels. I am judgeing this from the feel of stepping on and off the gas. anyone have this problem before, are the bearings in my tranny shot? thanks

had a similar experience truned out to be a seized wheel cylinder piston holding tthe shoe against the drum. it would get hot and bind, and grab.

check them and the tranny mounts

Also check your left motor mount isn't seperated.
