Hello everyone, I am new to the hummer forum.
I finally got my dream vehicle 07 h3. I love it.. it has some bad vibrations during accelerating and sometimes in curves or dips in road. Other than that it drives perfect at any speed, only vibrates during accelerating.. Thank you for any help

 

In front or back? Could be several things. Check your driveline. Worn bushings, shocks, cv joints (half shafts), front prop shaft ujoint or cv shaft or rear shaft ujoints.

 

Ok I will, thank you so much

 

I had a situation similar to this and it turns out I had a cracked U Joint on my rear driveshaft.
