The National Highway Traffic Safety Administration (NHTSA) on Wednesday (April 11) recalled almost 18,000 chassis that are being used for motorhomes, heavy-duty trucks, school and transit buses and fire trucks.

The manufacturers effected are Blue Bird Corp., Freightliner Corp. and Spartan Motors Inc.

The recall includes chassis with certain TRW tie rod assemblies built with 24-DL ball sockets. The tie rod ball-socket bearings have a below-specification case depth and/or hardness.

Dealers are to replace all defective ball sockets and/or drag links with new components, according to NHTSA.

The recall includes 16,000 Freightliner chassis. All are 1999 model year units. The Freightliner XC motorhome chassis was included in the recall along with Freightliner FLB, FLD, Century Class, Argosy, Cargo, FLN, S112, FS-65, Thomas Built MVP-EF, Thomas Built MVP-ER, Thomas Built Transit Liner ER, Orion II, Orion V, Western Star Constellation and Western Star Heritage heavy duty trucks, school and transit buses.

The federal agency also recalled 842 Blue Bird model year 1999 units including the Wanderlodge motorhome. Also recalled were Blue Bird’s All American, TC2000, Commercial Series and LTC (1999) school and transit buses.

A total of 780 Spartan model year 1999 through 2001 units were recalled. The Spartan K-2 motorhome chassis was included along with the Gladiator, MetroStar, Advantage and Low-Profile fire truck chassis.

NHTSA also issued the following RV industry-related recalls:

200 Fleetwood Enterprises Inc. Discovery model year 2001 motorhomes because the battery cable is routed too close to a sharp edge on the top of the automatic transmission. Dealers will inspect and replace or repair damaged cables, if necessary, and relocate the affected cables.

127 Winnebago Industries Inc. Minnie Winnie and Sundancer model year 2001 motorhomes with slideout walls in which the hose supplying liquid propane gas (LPG) to the refrigerator in the slideout did not have and adequate hose [email protected] at the extension mechanism. Dealers will re-route the LPG hose.

66,836 Reese Trailer Hitches from Reese Products Inc. The recall was issued because the interchangeable hitch balls, kit part numbers #57000, #57001 and #57002, which are affixed to a mounting post on a tow vehicle and with a vertically aligned plunger applied through the top center of the hitch ball, can work loose. Reese will provide a replacement kit to its customers free of charge.
