Service bulletin RX232 SpokeWheel

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

Technical Service Bulletin sent to customers who purchased RX232 spoked wheels from Gunite Corporation. The TSB identifies an issue with a limited subset of RX232 spoked truck wheels manufactured as part of lot code L019. In the foundry process, one ladle did not properly convert the material to ductile iron resulting in a single ladle pour producing a subset of wheels that cannot withstand the torque necessary to mount the wheels to the truck. The studs will pull out of an affected wheel and/or cause the wheel spoke to crack preventing the wheels from being installed. As such, the TSB communicates that wheels which have already been properly mounted and put into use do not contain the incorrect metallurgy and can remain in service. Wheels that are part of lot code L019 can be identified by a simple visual inspection of the part and returned for warranty coverage.
