Removal & Installation



Specific to:

Hummer H3 2006-2010


CAUTION
The front shock absorbers of the vehicle are multifunctional. In addition to contributing to a smooth ride they also provide the only stop to the front suspension when fully extended. Therefore, when servicing the shock absorber, service replacement shock absorbers must be equivalent to original shock absorbers in both extended length and strength. Use of shocks not complying to original equipment or strength could result in suspension over-travel or shock breakage. Suspension over-travel may result in suspension component breakage.

  1. Raise and support the vehicle.
  2.  
  3. Support the rear axle at ride height.
  4.  
  5. Remove the upper absorber bolts.
