Recall 15V859 affects 43 2015-2016 Freightliner trucks with loose axle-yoke hex nuts. Repair is free at any franchised Freightliner dealer.
Freightliner is recalling 43 2015-2016 108SD, 114SD, Business Class M2, and 4900 trucks because hex nuts on Marmon-Herrington drive axles were not tightened to specification. If those nuts loosen, the driveshaft can disconnect from the drive axle, causing loss of propulsion and raising crash risk; the Freightliner dealer repair will be free once available.

What's wrong?
The drive axle on the 2015-2016 Freightliner 108SD, 114SD, Business Class M2, and 4900 trucks sends engine power through the driveline to the wheels. At the axle, a flange yoke forms the bolted connection between the driveshaft and axle assembly. Hex nuts hold that connection tight so the driveline stays aligned under load.
On affected trucks, the hex nuts on the flange yoke were not properly tightened. That means the joint starts with less clamping force than it was designed to have. Driving torque and road vibration can work on that loose connection, leaving the axle assembly and driveshaft connection less secure than intended.
The recall information does not list an owner warning sign for this defect. There is no warning sign before failure.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
A loose driveshaft hex nut can let the driveshaft disconnect from the drive axle. That means the truck can lose propulsion in traffic, which increases crash risk. With no listed warning sign, schedule the inspection promptly and avoid putting off service. Repair will be free at any franchised Freightliner dealer once available.
What should I do?
- Check your VIN to confirm your 2015-2016 Freightliner 108SD, 4900, 114SD, or Business Class M2 is included in this recall.
- Contact a franchised Freightliner dealer to ask about the free drive-axle hex-nut inspection and tightening.
- Reference recall number 15V859 when you call so the dealer can find the correct campaign.
- Bring the recall notice if you have it, plus any service records for prior drive-axle or driveshaft work.
- Drive cautiously until the inspection is complete. Stop driving and contact the dealer if you feel driveline vibration, hear abnormal noise, or lose propulsion.
What happens at the repair
Once the dealer remedy is available, a Freightliner technician inspects the hex nuts on the drive axle flange yoke and tightens any that are not properly secured. The inspection and tightening are free under the recall. The issue involves the axle hardware that holds the flange yoke in place, so the dealer should check the specific Marmon-Herrington axle setup covered by campaign 15V859 before closing the repair order.

Recall 15V859 covers 43 2015-2016 Freightliner 108SD, 114SD, Business Class M2, and 4900 vehicles with drive-axle flange-yoke hex nuts that were not tightened correctly. The driveshaft can disconnect from the drive axle, causing loss of propulsion and increasing crash risk.
What should I do if my 2015-2016 Freightliner 108SD, 114SD, Business Class M2, or 4900 is on this recall?
Check your VIN to confirm your specific vehicle is included in recall 15V859. If it is, call a franchised Freightliner dealer and ask for recall FL-699. The dealer will inspect the drive-axle hex nuts and tighten them as needed for free.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to complete the recall repair at no cost, and the recall remedy says dealers will inspect the hex nuts and tighten them as necessary free of charge. Parts and labor are covered at a franchised Freightliner dealer.
What is the safety risk?
The safety risk is loss of propulsion while driving. If the flange-yoke hex nuts are loose, the driveshaft can disconnect from the drive axle. That can leave the vehicle without drive power and increase the risk of a crash.
