Hey all, I need some assistance. I just got my truck back from getting 4 inch rough country lift with 35 inch tires. At highway speeds of 65 or greater the truck feels like it's going to shake apart. It is not that present in the steering wheel but the rest of the truck is just shaking badly. The place I had the work done is closed for the day so I haven't been able to call them

Ok not helpful

start checking everything making sure stuff is tight , if rear driveshaft was not marked before removal to put a spacer on it could be off balance, otherwise there can't be many things that could cause that that I can think of off hand should be easy to figure out though if it shakes badly

Who did the lift? And do you have an alignment sheet for all 4 corners?

grantbalint

He told me they did not need to do anything with the driveshaft because the lift wasn't high enough. So I don't think it was that

grantbalint

No, I do not have an alignment sheet. Probably should've asked for one. The place that did it is called off-road innovations in Winchester Virginia

Check the alignment is number 1.

And tire balance is number 2

I just had an alignment done on my truck and the toe was out on one of my rear tires. I'd had a slight vibration before they fixed it. Could be something similar.

Also, you should check the pinion angle of the driveshaft. If it's too far out of spec, it could do the same thing.
