Now please dont get mad. I know this is a 67-72 forum, and i have a 68 c-10, but i have a question about my newer truck and there are a lot more people in this forum then the other one. I have a problem. I have a 1989 silverado single cab shortbox. I have a 1989 chevy shortbox. I am getting a vibration in the front end when i hit 45mph. It continues to vibrate even when i speed up , but it gets less noticeable because it vibrates faster. When i let off the gass at say 55 it stops, but when i step on the gas it starts up again. I crawled under the truck and looked at the four wheel drive drive axles, and the passenger side seems to be loose (able to move in and out a little bit and side to side) The driver side doesnt do it near as much. Anyone know what my problem is?

Sounds like it might the wheel bearing hub assm. jack it up, with jack stands, grab the wheel and see if it rocks. Try 12 and 6 o'clock position then 3 and 9. See where the play is, go from there

Yeah wheelsbearings or CV joints would be where I would look.With it going away when you let off the gas I would be looking at the axels,driveline area.

I would check the tires, anytime you have a problem with vibration. A knot on a tire or tread separating will drive you crazy.

My gut reaction is that one of the axels is out of balance.

My guess is CV or ball joints-whatever this truck has.

it would have both.

I would first suspect the U-joints in the driveshaft myself, then wheel bearings then CV joints.

Hope that it isn't wheel bearings.... trust me... pray it isn't bearings.
