Recall 11V142 affects 3 2006 Summit AD40 trailers for loose axle spindle nuts that risk wheel separation. Repair is free at any franchised Summit dealer.
Summit is recalling 3 2006 AD40 trailers because the spindle nut on certain ArvinMeritor trailer axles was not tightened enough, allowing excessive wheel-end movement. That looseness can progress to wheel separation and increase crash risk, and the Summit dealer repair will be free once the remedy is available.

What's wrong?
The axle assembly on the 2006 Summit AD40 is the wheel-end hardware that supports the trailer and lets each wheel rotate on the axle spindle. The spindle nut holds that wheel-end assembly in position, and the stake washer helps lock the nut so it stays tight during service.
On affected AD40 trailers equipped with ArvinMeritor TL series trailer axles, the spindle nut was not tightened with enough torque. The washer for that nut was staked in a single location instead of several locations, so the nut has less locking support than intended. If the nut loosens, the wheel-end assembly loses the clamp force it needs to stay properly seated on the spindle.
There is no warning sign before failure. Do not rely on noise, vibration, or handling changes to tell you the spindle nut has loosened.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific trailer is included.
What's the safety risk?
Low or missing torque on the wheel-end nut can allow excessive end-play in the wheel-end system. If the condition progresses, the wheel can separate and increase the risk of a crash. Confirm whether your VIN is included and schedule the recall repair soon. Repair will be free at any franchised Summit dealer once available.
What should I do?
- Check your VIN to confirm your 2006 Summit AD40 is included in this recall.
- Review any recall notice from Summit or Arvin Meritor before arranging service.
- Call Arvin Meritor at 1-248-273-4641 for repair instructions and reference recall number 11V142.
- Ask where to complete the free axle repair that corrects the loose spindle-nut condition in the wheel-end system.
- Avoid using the trailer until Summit or Arvin Meritor confirms the axle repair is complete.
What happens at the repair
At the dealer, a Summit technician checks whether the 2006 AD40 trailer has the ArvinMeritor TL Series axle covered by recall 11V142. The repair work centers on the axle spindle nut and stake washer. The technician corrects the axle hardware so the spindle nut is properly secured, then confirms the affected axle is repaired under the recall. The remedy notice says this work is free of charge, and the safety recall began on March 1, 2011.

Frequently asked questions
What is recall 11V142?
Recall 11V142 covers 3 2006 Summit AD40 trailers equipped with ArvinMeritor TL series trailer axles. Low or missing spindle-nut torque can create excessive wheel-end play and progress to wheel separation, increasing crash risk. The affected axle repair is free.
What should I do if my 2006 Summit AD40 is on this recall?
Check your VIN to confirm your specific trailer is included in recall 11V142. If it is, contact a franchised Summit dealer or service representative and reference recall number 11V142. The repair involves identifying and repairing the affected ArvinMeritor axle setup free of charge.
Is the recall repair free?
Yes. Federal recall law requires the recall repair to be performed at no cost, and the remedy states that ArvinMeritor is working with vehicle manufacturers to identify and repair affected vehicles free of charge. Keep recall number 11V142 ready when you call for service.
What is the safety risk?
The safety risk is wheel separation. Low or missing torque on the spindle nut can cause excessive movement in the wheel-end system, and that failure path can lead to a wheel separating from the trailer and a crash. Confirm the VIN before using the trailer.
What if I bought this Summit AD40 used?
The free recall repair still applies. Recall coverage follows the trailer VIN, not the first owner, so a used 2006 Summit AD40 remains eligible if its VIN is included. Check your VIN, then call a Summit dealer or service representative with recall number 11V142.
