Some 2005-07 Chevrolet Corvettes with automatic transmissions may produce a shudder or vibration through the steering column when turning the steering wheel with the engine idling.
According to GM, the condition may be severe enough to actually cause the shaking of some interior components, and is most likely due to insufficient fluid flow through the power steering pressure hose. Installing an improved design pressure hose should put a quick end to the trouble.
Order part No. 15903239 for vehicles with FE1 or FE2 suspensions; part No. 15903240 for models with FE3 or FE4 suspensions. You'll also need a retaining clip, part No. 88967174, to secure the new hose to the existing return hose, and on FE3 and FE4 suspensions, a screw, part No. 11609268, to secure the clip to the front crossmember.
