A washer provides a bearing interface in the designed hardware stack. At the specified cover attachment, using the correct washer helps preserve the intended seating between the fastener and mounting component.
Match the original part number, location and component order before ordering. Hole diameter alone is insufficient to select a replacement washer; outside diameter and thickness also affect the attachment. Do not add washers to an assembly that does not specify them.
Common reasons to replace
Replace a missing washer, visible deformation, damaged edges, severe corrosion or an altered bearing surface. Cover removal and component service can expose hardware that was lost, substituted or damaged during a previous repair.
Inspect the mating bolt, bracket and mounting hole whenever the hardware was loose or incorrectly assembled. A deformed mounting area or cracked panel requires repair beyond a new washer.
A washer will not correct an incorrect bolt length, damaged thread, missing bracket or damaged cover attachment. Check the complete hardware stack and mounting components before tightening the assembly.
Installation and service notes
Follow the factory procedure for access to the specified cover connection. Keep the original hardware grouped by position so that different washers and fasteners are returned to their intended locations.
Compare the washer number and dimensions with the original part and confirm the prescribed order of the bolt, washer and mounting components. Use one washer only where the parts diagram and repair procedure specify it.
Ensure that the washer sits flat on the intended bearing surface. Do not stack washers to compensate for an incorrect bolt or damaged mounting point, and do not modify the washer to force it over an incompatible fastener.
Follow the tightening specification for the actual bolt and connection. Washer dimensions do not establish a torque value. Inspect the cover alignment and mounting area if the washer does not seat normally.
Complete the required attachment and clearance checks after assembly. This listing supplies one small original washer, rather than a cover, bracket or complete installation kit.

Control-arm hardware service: This washer also appears in the specified control-arm mounting hardware on the A4 and A5 configurations above. Keep the original washer position and fastener stack, inspect the mating surfaces and use the procedure for that suspension joint.
