Defect

Heartland Recreational Vehicles, LLC (Heartland) is recalling certain 2019 Heartland Mallard, Pioneer, Sundance XLT, Wilderness, North Trail, Prowler and Trail Runner travel trailers. The axles may be missing inner bearing races on the hubs, which can cause the bearing to burnout or cause the hub to overheat.

Consequence

The missing bearing race may cause premature hub bearing failure, possibly resulting in a separation of the hub from the axle, thereby increasing the risk of a crash.

Remedy

Heartland will notify owners, and dealers will replace the defective hubs with new hubs or replace the axles, free of charge. The recall began October 9, 2018. Owners may contact Heartland customer service at 1-877-262-8032. Heartland's number for this recall is 99.01.40.
