TORRANCE, CA - Toyota Motor Sales plans to conduct a voluntary safety recall on approximately 51,000 model-year 2011 Tundra trucks to inspect the rear drive shaft.

The rear drive shaft in an estimated 0.05 percent of the vehicles may include a component (slip yoke) that could break as a result of improper casting during the foundry process, the automaker said.

Toyota said it is aware of one drive shaft slip yoke failure in a customer-owned vehicle. There are no reports of accidents or injuries associated with this condition. No other Lexus or Toyota vehicles are involved in this recall.

Owners of the involved vehicles will receive a letter advising them of this recall in May. Toyota will also post this information on its Web site.

Toyota dealers will be instructed to perform an inspection to identify a specific "production lot" number located on the rear drive shaft. Based upon the inspection results, in a limited number of cases, the rear drive shaft may need to be replaced.

The inspection is estimated to take 10 minutes. If the rear drive shaft needs to be replaced, the repair will take more time depending on the dealer workload. There will be no charge for this service.
