I lowered my truck, now it shakes!!!

[Nick Wilson]

I lowered it using Eibach springs and shackes and now it vibrates on roads it used to run smooth on. Is it simply that I need to align it, or what? This is a big problem because I drive 400 miles a week.

Have it aligned, I feel sure that is your problem. The springs being changed I suspect would have caused it but an alignment would bring it back to specs.

Is the vibration under acceleration? If so, you need to install pinion shims. You can get these from a local sport truck shop.

Thank's guys. It only does it during cruising down the highway. I will assume it is alignment because the camber went slightly positive in the front.
