What NHTSA recorded
Mounting of the pitman arm may loosen and lead to excessive wear in either the pitman arm splines or the steering gear shaft splines, or both. This condition is due to incorrect tightening of the mounting screws during assembly.
Remedy
The dealer will inspect and properly tighten the pitman arm retaining screws.
