1993 Ford F-350 Pick-up Vibration - Chassis, Suspension & Steering

Question: I have a 1993 F350 Superduty, standard transmission, 4 x 2, Gas truck with a 19' Jerr Dan flatbed I use for my business (towing) regardless if I am loaded or unloaded I am off and on experiencing some very rough, strong vibration that shakes the whole truck, it feels like the damn thing is going to shake apart, so much so it makes it difficult to steer and stop so far I have only had this happen doing 30 to 40 mph on back roads, not loaded doing 65 on the highway, nothing appears to be damaged, tires are new, brakes are all in good shape, steering components seems to be alright also, no obvious damage or trouble. What do you believe this could be?

Technican: It could be driveshaft related. I have run across several trucks with your described symptoms and have found the driveshaft out of balance.This is about all that comes to mind as long as the front suspension is all tight. and happy new year. ASE Master Tech
Owner: I thought that I would receive a more detailed response to my question. The answer was pretty general and broad. How do I fix it, where do I start to look? What am I looking for?
Technican: raise the rear end up until rear tires are off the ground. Support rear axle housing with jackstands. Start truck up and put into gear. Have an assistant raise mph of engine to your problem speed. Observe driveshaft for any vibration. You will also feel the vibration in the truck. This will be a good way to isolate it to the driveshaft. If it is the driveshaft, remove it and take it to your local driveshaft specialist (yellow pages)and they can rebalance it or suggest replacement. To check your front end for play, raise the front of the truck off the ground. grab the front tire (left or right) and try to move it side to side by grabbing the tire at the 9 & 3 position observe any loose feeling. this checks the tie rod ends, idler arm, & pitman arm for looseness. Next grab the tire at the 12 & 6 positionand try to move the tire back and forth... this checks for bad ball joints. You will also be able to see if the wheel bearings are loose. Hope this is a bit more detailed. For more in depth explainations you can Email me at upon accepting this
