My hummer is swinging after 60 km/h , i tried many workshops each one aske me to change shocks , front arms and steering arm and still has same problem did that happen with any one?? Whats the solution?

 

Steering stabilizer?

have they check your stabilizer links and bushes?

 

Are your bump stops present?

also h2 is never going to handle like a slot car racer......

the bump stops tops are most likely missing on your front arms - they are integral to your front suspension diving and wobbling -

let us know -

 

Also - if you have “steering drift” your steering gear box is also probably shot. Common on these.

 

thanks for responding, yes bump stop feont and rear is new as well

 

How about the front hubs?

 

Hub is good , bearings are new 😕

 

What air pressure are you running in the tires? Have you tried rotating your tires front to rear to see if that changes anything?
