• 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.
• Keeping the old part until the new one is fitted and checked is the simplest way to avoid a second order.

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.
