RN
Reviewed by the RecallNotify editorial team
Published May 25, 2026

Recall 17V593 affects 17,737 2016 Peterbilt trucks with loose tie rods that can cause steering loss. Repair is free at any franchised Peterbilt dealer.

Peterbilt is recalling 17,737 2016 trucks, including 567, 220, and K170 models, because the castellated nut on certain Spicer D or E series steer axles was not properly torqued. A loose tie rod can disconnect from the steering knuckle, causing complete loss of steering and crash risk; Peterbilt dealers will complete the repair free of charge.

What's wrong?

The tie rod is part of the steering linkage on these 2016 Peterbilt trucks with certain Spicer D or E series steer axles. It connects the steering system to the steering knuckle at the front wheel, so the wheel turns when the driver turns the steering wheel. A castellated nut holds that tie rod end tight in the knuckle.

On affected trucks, that castellated nut was not tightened to the correct torque during axle assembly. With too little clamping force, the tie rod connection can loosen over time. If the joint separates, steering input no longer controls that front wheel as designed.

The warning sign is front-end noise, a clunk from the steering area, or loose steering feel. Those symptoms mean the tie rod end connection needs dealer inspection before the truck stays in service.

Who's affected?

Scope spans medium-duty and heavy-duty truck lines, with each model listed for both the tie rod and the broader steering system.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific truck is included.

What's the safety risk?

A loose tie rod can disconnect from the steering knuckle, causing complete loss of steering and increasing the risk of a crash. Front end clunking or loose steering is a warning sign. If you notice either, stop using the truck and call the dealer. Repair is free at any franchised Peterbilt dealer.

What should I do?

  1. Check your VIN to confirm your 2016 Peterbilt truck is included in this recall.
  2. Contact a franchised Peterbilt dealer to schedule the free tie-rod torque inspection and repair that keeps the steering tie rod secured to the knuckle.
  3. Bring the recall notice if Peterbilt mailed one. If not, reference recall number 17V593 when you call.
  4. Ask the dealer whether the castellated nut and tie rod only need tightening or whether the knuckle and tie rod end assembly need replacement.
  5. Stop driving and call the dealer if the steering feels loose or the truck wanders before the repair.

What happens at the repair

At the dealer, a Peterbilt technician inspects the steer axle castellated nut and tie rod torque, then tightens the hardware where needed. If the tie rod stud and knuckle cannot be tightened to specification, the dealer replaces the knuckle and tie rod end assembly. The recall repair is free, with parts and labor covered. PACCAR has a general reimbursement plan on file for this campaign. If you've already paid for a related tie rod, knuckle, or steering repair, bring your repair invoice and payment records to the service desk.

Frequently asked questions

What is recall 17V593?

Recall 17V593 covers 17,737 2016 Peterbilt trucks equipped with certain Spicer D or E series steer axles. The castellated nut on the steer axle was not properly torqued, which can let the tie rod loosen and disconnect from the steering knuckle.

What should I do if my 2016 Peterbilt truck is on this recall?

Check your VIN to confirm your specific truck is included in recall 17V593. If it is, contact a franchised Peterbilt dealer and ask for the steer axle tie rod inspection. Reference recall number 17V593 and Peterbilt recall number P817-C when you call.

Is the recall repair free?

Yes. Federal recall law requires the manufacturer to repair the defect at no cost. The dealer will inspect the castellated nut and tie rod torque, tighten the parts when needed, and replace the knuckle and tie rod end assembly if proper torque cannot be achieved.

What is the safety risk in recall 17V593?

The safety risk is loss of steering. If the tie rod loosens and disconnects from the steering knuckle, the truck can lose steering control and crash risk increases. The free dealer inspection checks the torque and corrects the steering linkage before that failure occurs.

What if I bought the Peterbilt truck used?

The free recall repair still applies. Recall eligibility follows the VIN, not the first owner. Check your VIN to confirm whether your truck is included, then call a franchised Peterbilt dealer and reference recall 17V593 so the service desk can find the correct repair procedure.
