Ive recently had the front suspension redone along with replacing rear shocks. When on my way to check out a 14 bolt I noticed a strange vibrating sound and vibrations starting around 45mph and up. Took the truck back to the shop and they didn't find anything. Took it to other one and it seemed that it had bad wheel alignment and bad front tires. I've replaced front tires (tires were balanced on a machine) did the alignment and it's still there. Left the truck at the shop that did the first work and they still didn't find anything! Did someone had similar issues?
