Hey everyone, I need some assistance with a issue that just started... my G is wobbling driving at speeds 20mph an greater!! The steering wheel is not shaking at but u feel in the whole car. It feels like I’m driving on a flat tire but all tires are inflated... please for some help!!!

 

First check the torque on your lugnuts, should be 80 ft/lbs, next have a local tire shop balance your tires, don't be surprised if they tell you one of the tires has failed from delamination or something.

 

I appreciate the information I will check first thing in the morning... the **** is just crazy because one second I was riding on the highway fine to the next minute it feels like I’m riding a horse!!!

 

Something suspension related broke or your lug nuts are loose. Start with something easy.

 

What could be wrong with my suspension?? Is there anything I can check myself??

 

Ok so my day consisted of checking tires all day an to find out my back rear tire had separation!!! I appreciate the advice from everyone!!

She’s getting fixed

 

Glad the OP got the problem fixed. I had something that sounded like this just recently and thought I'd share even though it's embarrassing. I replaced the drivers side front axle on my 06X about a year ago. I didn't use any thread lock agent and must not have tightened everything sufficiently because my axle came unbolted from the front diff. As it was coming unbolted it wobbled a bit like badly out of balance tire. I should known something was up and not ignored the little click i heard when putting it into reverse. Replacing the axle was easy enough (with thread lock this time) but the axle broke a switch on my ac compressor which will have to be replaced. Lesson learned... don't ignore wobbles and clicking noises in your drivetrain.
