What's wrong?
The rear axle hub on these 2019 Heartland North Trail, Wilderness, Trail Runner, Mallard, Pioneer, Prowler, and Sundance XLT Tt travel trailers carries the wheel on bearings. Those bearings need an inner bearing race, also called a bearing cup, so the rollers have a smooth, fixed surface to turn against while the trailer is moving.
On affected trailers, the D44 axle hub was built without that bearing cup during manufacturing. Without the cup in place, the bearing does not sit or roll correctly inside the hub. Friction builds, the bearing can burn out, and the hub can overheat instead of carrying the wheel smoothly.
The first sign is heat at the hub. Burning grease can produce smoke, and the wheel can begin to wobble as the bearing loses support. If you notice smoke, heat, or wheel wobble, stop using the trailer and have the axle hub inspected before moving it again.
Who's affected?
Covers seven Heartland travel trailer lines from the 2019 model year, all tied to the rear suspension.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific trailer is included.
What's the safety risk?
A missing bearing race can make the hub bearing fail early. If the hub separates from the axle, crash risk increases. Heat at the hub, smoke from burning grease, or a wobbly wheel are warning signs to stop towing and call the dealer. Repair is free at any franchised Heartland dealer.
What should I do?
- Check your VIN to confirm your 2019 Heartland North Trail, Wilderness, Trail Runner, Mallard, Pioneer, Prowler, or Sundance XLT Tt travel trailer is included in this recall.
- Contact a franchised Heartland dealer to schedule the free hub or axle replacement that fixes the missing inner bearing races.
- Bring the recall notice if Heartland sent one, or reference recall number 18V634 when you call.
- Tow cautiously until the repair is complete, and stop safely if a hub overheats.
- Call Heartland customer service at 1-877-262-8032 with questions and reference Heartland recall 99.01.40.
What happens at the repair
At the dealer, a Heartland technician checks the trailer axle hubs, replaces the defective hubs with new hubs, or replaces the axles when the hub condition calls for it. The recall repair is free, and parts and labor are covered. Heartland has a general reimbursement plan on file for owners who already paid for this axle hub repair before the recall work was completed. Keep repair paperwork and ask Heartland customer service how to submit documented expenses.

Frequently asked questions
What is recall 18V634?
Recall 18V634 covers 622 2019 Heartland travel trailers with axle hubs that can be missing inner bearing races. The defect can cause bearing failure, hub overheating, or hub separation from the axle, increasing crash risk. Heartland dealers will replace defective hubs or axles for free.
What should I do if my 2019 Heartland North Trail, Wilderness, Trail Runner, Mallard, Pioneer, Prowler, or Sundance XLT Tt is on this recall?
Check your VIN to confirm your specific trailer is included in recall 18V634. If it is, contact a franchised Heartland dealer to schedule the hub or axle repair. Reference recall 18V634 and Heartland recall number 99.01.40 when you call.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to repair the defect at no cost, and Heartland dealers will replace the defective hubs with new hubs or replace the axles free of charge.
What is the safety risk?
The safety risk is wheel-end failure. A missing inner bearing race can cause the hub bearing to fail early, overheat, or separate from the axle while the trailer is moving. That separation increases crash risk, so schedule the free dealer repair if your VIN is included.
What if I bought my Heartland trailer used?
The free recall repair still applies. Recall coverage follows the trailer, not the first owner. Check your VIN to confirm whether your specific 2019 Heartland trailer is included, then call a franchised Heartland dealer or Heartland customer service at 1-877-262-8032.
