Service bulletin 02-168

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

The lack of clearance could result in cracked/broken quarter fenders or complete separation if undetected or un-remedied.
