Recall 11V170 covers 80 2005-2008 Kwik M4000 converter dollies for loose axle spindle nuts. Repair will be free at any franchised Kwik dealer once available.
Kwik is recalling 80 2005-2008 M4000 converter dollies equipped with ArvinMeritor axles because the spindle nut on the TL Series trailer axle lacked enough torque. Low torque can create excessive wheel-end play and progress to wheel separation, which raises crash risk; the dealer repair will be free once available.

What's wrong?
The axle assembly on a 2005-2008 Kwik M4000 converter dolly supports the wheel ends that carry the dolly and trailer load. On these dollies, the ArvinMeritor TL Series trailer axle uses a spindle nut to hold the wheel-end parts in the correct position on the axle spindle. A stake washer helps lock that nut so it stays tight while the dolly is in service.
On affected M4000 dollies, the spindle nut was not tightened enough during assembly. The washer was staked in a single location instead of multiple locations, which gives the nut less protection against movement. If the nut loosens, the wheel-end parts do not stay clamped as designed, and the axle assembly can develop unsafe movement at the wheel end.
There is no warning sign before failure. A driver or fleet technician should not rely on noise, vibration, or handling changes to confirm the problem before inspection.
Who's affected?
Spans the 2005, 2006, 2007, and 2008 model years, all tied to the drive axle.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether this recall applies to your specific vehicle.
What's the safety risk?
Low or missing torque on the wheel end nut can let the wheel end develop excessive end play. If that progresses, the wheel can separate from the vehicle and increase the risk of a crash. Schedule the recall repair soon. Repair will be free at any franchised Kwik dealer once available.
What should I do?
- Check your VIN to confirm your 2005-2008 Kwik M4000 converter dolly is included in this recall.
- Wait for Kwik repair instructions or call the listed contact before scheduling work because the remedy status is not listed as available.
- Call Kwik or Arvin Meritor at 1-248-273-4641 with questions, and reference recall number 11V170 when you call.
- Ask about the axle spindle-nut and stake-washer repair that corrects loose wheel-end hardware on the ArvinMeritor axle.
- Limit use until the axle repair is complete, and ask the repair provider whether the dolly needs to be moved by tow or service transport.
What happens at the repair
Kwik has not provided an owner notification schedule, so do not treat this as a repair that is ready to schedule. Once the repair is available, a Kwik technician or authorized repair provider will identify whether the converter dolly has the affected ArvinMeritor TL series axle. The repair addresses the spindle nut and stake washer condition on the axle and will be completed free of charge.

Frequently asked questions
What is recall 11V170?
Recall 11V170 covers 80 2005-2008 Kwik M4000 converter dollies equipped with ArvinMeritor TL series trailer axles. The axle spindle nut was not torqued enough, which can create excess wheel-end play and lead to wheel separation. The repair is free.
What should I do if my 2005-2008 Kwik M4000 is on this recall?
Check your VIN to confirm your specific converter dolly is included in recall 11V170. If it is, contact a Kwik dealer or ArvinMeritor at 1-248-273-4641 and reference recall number 11V170. The axle repair is free.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to repair the defect at no cost, and the recall remedy says ArvinMeritor is working with vehicle manufacturers to identify and repair affected vehicles free of charge.
What is the safety risk?
The safety risk is wheel separation. Low or missing spindle-nut torque can create excessive end-play in the wheel-end system. If the wheel separates while the converter dolly is in use, the loss of the wheel can result in a crash.
What if I bought my Kwik M4000 used?
The free recall repair still applies. Federal recall law follows the vehicle, not the first owner. Check your VIN to confirm whether your converter dolly is included in recall 11V170, then contact a Kwik dealer or ArvinMeritor for the repair path.
