You I have a 1997 Chevy...
You
I have a 1997 Chevy c6500 rollback. When I hit around 45mph the truck hops, bounces and shakes. I've replaced the carrier bearings...u joints and front tires. I was told that the front wheels are rusty and that could be the problem. One mechanic said the drivers side kingpin is bad. Another mechanic saw no issues with the front end. I'm lost. I've already dumped a lot of cash into this truck with no luck.

Is the shake on the front wheels or the total truck? Get a chase car and drive and watch the truck as it start to act up, and see what is shaking. Need to find what is shaking and then isolate it. It may be a rear wheel or tire. Or if in front, can be a brake that broken and is out of balance.

The whole truck. Cab...etc. Replaced cab mounts as well. Had new steer tires installed but the last mechanic that looked at it said that the wheels on the front could be warped or out of balance and said the front end looks good. Another mechanic said the kingpin is bad. I'm not trying to continue to dump money and the problems still persists.

We had a roll back , that had same problem, we used chase truck to find problem was drive line out of balance.
