The f shield here is the GM part, numbered 85555138. It is catalogued under Covers & Caps > Shields & Guards.

• Torque figures belong to the fastener and the joint rather than to the part, so the factory procedure is the reference rather than a general rule.
• A part that fails early usually points at an installation fault or a worn component nearby rather than at the part itself.
• Where a diagram shows several similar items on one assembly, the difference between them is normally length, shoulder or handedness.

Covers that seal a fluid opening normally carry a single-use gasket or O-ring, and reusing the old one is the usual reason a leak comes back. Superseded numbers are common, and where a factory number has been replaced the current part is usually dimensionally identical to the original.

Match this against the part you are taking off rather than against a photo. If the number is unreadable, send us the VIN and we will confirm it. In stock and sent from the US in one to two business days, free delivery over $59.
