What's wrong?
The Dexter D30 axle on the 2021 Grand Design Imagine is the beam and hub assembly that carries the trailer's weight and lets each wheel rotate on bearings. The inner bearing supports the hub on the axle spindle, so the wheel turns smoothly while staying held in the correct position.
On affected trailers, Dexter assembled a suspect axle batch with the wrong inner bearing. The correct bearing is marked LM67048, while the incorrect bearing is marked L68419. Because the bearing size is wrong, the hub does not sit on the spindle as designed. That mismatch leaves excess movement in the hub and changes how the axle supports the wheel.
The warning sign is excessive end play, which means the hub has too much in and out movement when it is checked. Owners are unlikely to read bearing markings without inspection, so use the dealer inspection process for recall 21V636 to confirm the axle and bearing.
Who's affected?
The same Dexter D30 axle appears under both axle hubs and axle assembly, so the component labels differ while the affected axle is the same.

What's the safety risk?
Incorrect inner bearings can let the wheels lock up or reduce braking ability, which increases crash risk. Excessive axle hub end play is the warning sign tied to this defect, so stop using the trailer and call a Grand Design dealer if it appears. Repair is free at any franchised Grand Design dealer.
What should I do?
- Check your VIN to confirm your 2021 Grand Design Imagine trailer is included in this recall.
- Contact a franchised Grand Design dealer to schedule the free Dexter D30 axle inspection.
- Schedule the inner-bearing replacement if the dealer finds incorrect bearings, which addresses wheel lockup and reduced stopping ability.
- Bring the recall notice if Grand Design mailed one. If not, reference recall number 21V636 and Grand Design recall 910024 when you call.
- Tow cautiously until the inspection or repair is complete. Leave extra stopping distance and stop using the trailer if a wheel drags, locks, or feels abnormal.
What happens at the repair
At the dealer, a Grand Design technician inspects the axles on the 2021 Imagine trailer for incorrect inner bearings. If the wrong bearings are found, the technician replaces the bearings. The inspection, replacement parts, and labor are free under recall 21V636. Grand Design says owners who already paid to have this service performed will be reimbursed for expenses related to this defect. Keep the repair invoice and payment records, then contact Grand Design customer service or ask the dealer service desk how to submit the reimbursement claim.
