Service bulletin TI-51-13

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.

With the current data record for regulating the rear-differential lock, there may be increased wear on the pinion shaft on the servo motor for the rear-differential lock as a result of extreme driving over the service life of the vehicle. This can cause noises and can subsequently impair the function of the rear-differential lock.
