60-65mph vibration/shaking

Many of the newer LT's at work do/did the same thing. I believe some of them stopped when a part that connected the cab to the chassis was replaced. It was visibly worn out when viewed from behind the cab. God I wish I could remember what the hell it was. It was not a tire or alignment issue.

 

I checked my ride height and its half an inch lower then it should be,ill update if this solves the problem

 

My mistake, it was the hanger bearing, that's what it was causing shakes on some of our LT's. Check that.

 

Did you fix it? I’m in the same boat

 

No f this truck lol

 

Over 60mph balance problem according to Mike Beckett of MD Alignment.

We had several LT's that shook in the steering wheel around 50-62 mph, accelerating. Turned out our alignment guy sucked, we took them to a new shop and the new alignments are holding up a lot better.

 

Mine wasn’t in steering felt like it was more less back end like driveline or suspension.

 

Did you end up finding solution, I have same exact problem, thanks

 

Yes and no I replaced the leveling valve and it helped. Then on an unrelated issue I replace the cab shocks cuz an air leak and it did much much better. It vibrates sometimes but no when I’m loaded. I still need to
Adjust the leveling valve to specs. Just been lazy since I’m always loaded
