• Corrosion at a mounting face is worth cleaning back before fitting anything new, because a part that sits on scale will work loose.
• 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.

The number stamped on the old part is the only reliable identifier, since two parts can look identical and differ by a millimetre or by rotation direction.

Check the number on the part you are removing before ordering. If it is worn off, send the VIN and a photo and we will match it. Dispatched from our US warehouse within one to two business days, with free shipping over $59.
