H3 vibration above 55-60mph
 

Hey All,

I took the rig in to have both axle seals replaced by the dealer and the transmission flush service. After picking up the vehicle and getting up to highway speeds I felt a bad front end vibe and to the point where it was noticeably shaking the steering wheel. I took it back to the dealer and they said nothing was loose but I needed new tires. Mind you this wasn't happening before I brought it in for the initial repairs.

I'm just wondering what it could be if nothing's loose? Maybe they installed the shafts back incorrectly? The seals aren't set right? I had the front end realigned after they did the repairs and still notice the vibe. Thanks

Check to see if they knocked off a wheel weight or 2 when they removed and reinstalled the rims/tires. There should be a slight mark in the rim where a weight would have been.

Stating the obvious, but look to make sure all lug nuts are in place. I had a tire shop strip a lock nut years back, rather than tell me, they just left it off. One missing lug nut creates a bunch of vibration.

Agree. It makes a lot of racket and vib's.

If your tires are worn some esp. from not being aglined properly if they re-installed the front tires on the opposite sides it could possibly cause some vibs too.
The wheel weights would be my first guess.
