New owner here and love the H2 already. When I bought it I knew it had this issue of sounding/feeling like you are on the rumble strip whenever you are driving between 45-55mph... before and after that rides quit and great (was really impressed by the ride as I was expecting it to ride like a log wagon. Just trying to get an idea of what this is so I can get the parts to fix rather than just start replacing expensive parts. Any help would be greatly appreciated👍

 

Wheel bearings, CV axles are a possibility, I would take it to an alignment shop that you trust and ask for a front end inspection.

That is a great looking rig, congratulations.

 

old worn or bad tires, wheels need balancing?

 

Could possibly be a worn U-Joint.

 

Trusted mechanic turned me on to this and it has worked! I would’ve thought it was snake oil but tried anyway and it truly was instant fix. Now to see how long it lasts👍

 

Lubegard is the best transmission additive and is a good thing to add even if you are not experiencing any issues.

 

I had that same issue with my truck once it hit 40mph. Stopped changing parts because nothing helped. At 115k miles my rear pack in trans was leaking so I swapped out trans and that vibration is no longer there. I would say it's the trans.

 

I had a weird shudder and vibration in 4th gear also around 45-50mph, swap the 4 selonoids in the tranny, the shop charged me 200 for the tranny service and swapping the parts I provided, amazon list tranny parts https://a.co/ag6XNK6, fixed it 90%, also my motor was unhappy feeling hitting 45 also and did the coils, wires, plugs and bam 100% gone https://a.co/gi7CctQ coils list
