Front Non-Drive Steer Axle Part No. : FL941 & MFS Series Size : NR Function : Axle
Descriptive Information : This recall involves axles produced by Meritor using suspect tie rod clamps supplied to Meritor between December 16, 2021 and May 16, 2022.
Production Dates : DEC 16, 2021 – MAY 16, 2022
Description of Defect :
Description of the Defect : Based upon information provided by Meritor’s supplier, due to a heat treat issue, Meritor has determined that a population of tie rod clamps used in the manufacture of the subject axle population may be susceptible to cracking. Over time, a crack may lead to a complete fracture of the clamp, thereby reducing clamp load to the tie rod end. If both clamps on the tie rod were to fail, the cross tube could start to unscrew, vehicle alignment issues would evolve, and there is a potential for the tie rod end to separate from the cross tube. Separation is more likely to occur when tie rod loads are highest, which is at slow vehicle speeds over rough terrain or turning maneuvers.
FMVSS 1 : NR FMVSS 2 : NR
Description of the Safety Risk : Separation of the tie rod end from the cross tube could result in partial loss of vehicle steering capability, increasing the risk of a crash.
Description of the Cause : Excessive carbon caused by a damaged control board on one of four furnaces at the supplier.
Identification of Any Warning The initial effect would be a vehicle out of alignment. If both clamps on the tie Part 573 Safety Recall Report 22E-085 Page 2 that can Occur : rod cracked, the tube could rotate and result in a partial loss of steering capability.
