This has me stumped.

I get a random vibration when driving my truck. This morning to work nothing. Went to Home Depot, nothing. Then when to lunch and it was there, started at 20mph and went away at 35mph. Another run to HD, no issues. Then on the ride home from 20mph to about 50 it was back. Seems more pronounced when accelerating.

Running 20" rims with Nitto Tires. Tires do not have any sign of cupping on them. I do not see and missing weights on the rims. I checked the drive shaft u-joints and there is no play. No sound like a bearing is going bad.

Problem does not exist all the time.

What should I check next?

 

could be the emergency brake, intermittently hanging up. Had it happen on a 07 F150 with the same type of symptoms.

 

Are your hubs locked in? I'd check U joints and carrier bearing, maybe your tires need balanced? I had a truck that the steers were out of balance sometimes it wasn't bad but when they were harmonic they really shook the truck

 

Thanks for the suggestion jimmyb on the parking brake. The drivers side was hung up. Had the rotors turned as well. Vast improvement.

This weekend I plan on pulling the front apart to check out u joints and have the fronts turned.

 

Happy to be able to help!
