What's wrong?
The tie rod assembly on 2015 Mack Chu and Pinnacle (Cxu) trucks is part of the steering linkage. It connects the steering gear to the front wheels so the wheels turn when the driver turns the steering wheel. Each end uses a ball socket, which lets the linkage move with the axle while still holding the steering connection in place. A collar keeps that socket from backing out.
On affected trucks, the collars that hold the ball sockets in position were incorrectly placed during manufacturing. If a collar is out of position, it does not keep the ball socket fully secured in the tie rod. As the socket loosens, the steering linkage develops unwanted movement, and steering response becomes less predictable. The defect is tied to the collar position, not normal wear.
There is no warning sign before failure. A driver should not count on noise, vibration, or a change in steering feel before the ball socket comes loose.

What should I do?
- Check your VIN to confirm your 2015 Mack Chu or Pinnacle (Cxu) is included in this recall.
- Watch for Mack's owner notice before scheduling dealer work; Mack mailed owner notices on January 20, 2015.
- Contact a franchised Mack dealer once the repair opens to arrange the free tie-rod collar inspection and repositioning that keeps the ball sockets secured.
- Reference recall number 14V737 when you call Mack or the dealer.
- Drive cautiously until the inspection is complete, and stop driving if steering feels loose or abnormal.
What happens at the repair
When the final dealer repair is available, a Mack technician will inspect the tie rod collar and re-position it when needed so the ball sockets stay secured. Parts and labor are covered under the recall. Mack's reimbursement plan reviews owner-paid repairs from before the recall notice case by case under its general reimbursement plan. If you've already paid for a related tie rod or collar repair, keep the invoice and service paperwork so Mack can review the claim.
