Creak or Squeak Noise
This information applies to 2005-06 full size utilities, Cadillac Escalade, Chevrolet Avalanche, and HUMMER H2 built after May, 2005.
Owners may comment of a creak or squeak type noise on acceleration, deceleration, over bumps, turns or garage shifts. This noise may sound like it is from the front or the rear of the vehicle.
This noise (felt or heard using Chassis Ears) may seem to be coming from along the entire frame side rail or body mount areas.
In some cases, the noise may sound like loose lumber while driving on a minimally rough road surface while driving straight or turning.
IMPORTANT: This noise can sound like it is coming from the propshaft. Do not replace the propshaft for this condition.
This noise could be coming from the rear lower control arm bushings. The squeak is caused by relative movement of the bushing to the control arm flange.
To help isolate the noise to the control arm bushing, spray penetrating oil (WD-40 or equivalent) on the bushing to the control arm area.
If the noise is eliminated or reduced, replace the control arm assembly.
