Condition/Concern:

Some customers may comment on a lack of steering assist or shudder during parking lot type maneuvers.

This valve will provide additional steering assist during parking lot type maneuvers. If this concern occurs when stopped or at very slow speeds with brakes applied, please reference PIT3310.

 

Please follow this diagnosis process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

Got the new valve from gmpartsdirect. Valve looks like it needs a couple o-rings to seal. Asked the dealer if they had any. They pulled up a schematic that shows an o-ring but they have no part number for it. They said "not servicable". What's up with that? Anyone replaced one of these?

The TSB for that (Bulletin # 05-02-32-008A) list part # for the O-ring seals as 26001594. Try that number and let me know if it helps.
