70 D200. I repacked the bearings, replaced seals and adjusted the front brakes. Now I have a bad shake under any acceleration. Doesn't seem to do it if I coast. Everything seems tight and nothing wobbling when jacked up. Now I'm wondering If I did something or this is coincidental. Kind of acts like a engine miss but, seems to run OK. Any ideas if somethings up with the suspension before I look elsewhere? Thanks Craig

Typicaly if front end parts are bad you'll get a side to side movement in the steering wheel and if tires are a problem you'll get an up and down vibration/movement in the steering wheel. Engine miss fires create a noticable vibration when the engine is under a load and subside when the load is released. I guess the question is do you feel the vibration in the steering wheel or through the body of the truck? Seat of the pants or hands.

I've had a similar issue that turned out to be a tire. Did you rotate your tires while they were off? Try swapping them to the rear one at a time and see if the issue stops.
