Service bulletin A401333 2026402-

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.

NHTSA's summary

Supersedes Technical Service Bulletin Group 40 number 11-18 dated July 14, 2011. When a control arm or wheel bearing housing (swivel bearing) is replaced, additional parts must be replaced due to a supersession of service parts. Due to further technical development, new design control arms were implemented during 2011 production. Control arms and axle joint journals with diameter M14 (previously M12) are now fitted to all production vehicles.
