What's wrong?
The tag axle on the 2007-2008 Spartan K2 and Mm motorhome chassis is a rear, non-powered axle that helps carry the weight of the completed motorhome. Its wheel bearings let the wheel end rotate with low resistance while holding the wheel hub in the correct position. This setup depends on the bearing adjustment being loose enough for smooth movement but tight enough to keep the wheel end stable.
On affected chassis, the bearings were installed too tight. That extra preload makes the bearing move with more resistance, so heat builds in the tag axle wheel end during use. The correct setup gives the bearing more room to move and reduces that resistance.
Owners can see signs of overheating at the tag axle. Watch for distortion or melting of the Stemco cover, or for the ABS warning lamp to come on.
Who's affected?
Spans the K2 and Mm across the 2007 and 2008 model years, with the rear suspension named for both models.

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?
Overheated wheel bearings increase the risk of a wheel-end fire. Watch for distortion or melting on the Stemco cover, or an ABS lamp, and treat either sign as a reason to park safely and call the dealer before another trip. Repair is free at any franchised Spartan dealer.
What should I do?
- Check your VIN to confirm your 2007-2008 Spartan K2 or Mm motorhome chassis is included in this recall.
- Contact a franchised Spartan dealer to schedule the free wheel-bearing load adjustment and bearing replacement that prevents tag-axle bearing overheating.
- Bring the recall notice if Spartan mailed one. If not, reference recall number 15V548 and Spartan recall 14015 when you call.
- Avoid extended driving until the repair is complete, since overheated wheel bearings increase the risk of a wheel end fire.
What happens at the repair
At the dealer, a Spartan technician adjusts the wheel bearing load on the tag axle and replaces the wheel bearings when inspection shows replacement is needed. The recall repair is available, and parts and labor are free of charge. Spartan has a general reimbursement plan on file for owner-paid repairs tied to this recall. If you already paid for a related wheel bearing repair before the recall work, bring documentation to the service desk and ask how Spartan's reimbursement plan applies.
