On March 21, 2012, Carlisle Transportation Products (Carlisle) notified the NHTSA that it had decided a defect exists in certain 908 Yuma, 910 Intruder, and 921 Intrepid series Black Rock toy hauler trailer wheels.These trailer wheels were manufactured from August 9, 2010, through February 7, 2012, and were sold and installed as original equipment for use on various boat, camper, and utility trailer vehicles.These wheels were manufactured with machine dimensions for the application of a center cap and the application of steel lug inserts that were not controlled to the required blue print specifications.As a result, the wheel may not be tightened to proper torque requirements during the mounting process.This condition could allow the wheels to loosen, leading to wheel separation, and possibly a vehicle crash.A detached wheel also becomes a road hazard.This matter was assigned recall number 12E-011.On July 26, 2012, the Recall Management Division (RMD) mailed Information Request (IR) letters to ten (10) companies identified through a purchaser list submitted by Carlisle.On October 1, 2012, RMD mailed a second IR letter to three (3) companies that did not respond to the earlier letter.All companies contacted did eventually file a written response with RMD.Three (3) companies explained that their affected trailer wheels were returned to Carlisle prior to installation onto new or used trailers.The remaining seven (7) companies filed Part 573 Reports and conducted safety recalls for their affected trailers. The following seven (7) recalls were filed as a result of this EQ:12V-385California Trailer Works 12V-396B&M Mfg., Inc. 12V-414McClain Trailers 12V-418Lippert Components (Extreme Trailers) 12V-512Express Trailers 12V-517Forest River Texas Group 12V-520Aluminia, Inc.All wheels affected by this safety defect have been identified and a recall campaign conducted where applicable.Accordingly, this EQ is closed.
