What's wrong?
The tie rod on 2015 E-One Cyclone Ii and Quest Ii emergency vehicles is part of the steering linkage, the set of bars and joints that carries steering input from the steering gear to the front wheels. A castellated nut is a slotted retaining nut that holds the tie rod connection tight and lets a locking pin keep it in place. When it is torqued correctly, the front wheels stay aligned as the steering moves across the axle.
On affected vehicles, castellated nuts on certain Spicer D-Series and E-Series steer axles were not properly torqued during assembly. With too little clamp force, the tie rod joint can loosen as the vehicle is driven. If that joint keeps moving, steering play increases and damaged parts can require replacement during the inspection campaign.
Owners or operators can notice significant noise from the front axle or looseness in the steering before the tie rod connection fails. Treat either sign as a warning sign and have the steering linkage inspected.

What's the safety risk?
A loose tie rod can separate from the steering knuckle, causing complete loss of steering and increasing crash risk. Significant noise or loose steering is a warning sign. If either appears, stop using the vehicle and call the dealer before moving it again. Repair is free at any franchised E-One dealer.
What should I do?
- Check your VIN to confirm your 2015 E-One Cyclone Ii or Quest Ii is included in this recall.
- Contact a franchised E-One dealer to schedule the free inspection and tie-rod repair that secures the steering linkage.
- Ask the dealer to inspect the steer-axle castellated nut and tie rod, then tighten the hardware or replace the knuckle and tie rod end assembly if needed.
- Bring the recall notice if E-One mailed one. If not, reference recall number 17V540 when you call.
- Avoid unnecessary driving until the dealer confirms the tie rod is secure and the repair is complete.
What happens at the repair
At the dealer, an E-One technician inspects the torque of the castellated nut and tie rod, then tightens the hardware as needed. If the tie rod stud and knuckle cannot hold the required torque, the dealer replaces the knuckle and tie rod end assembly. The recall repair is free, with parts and labor covered. E-One has a general reimbursement plan on file, so owners who already paid for a related repair should contact E-One customer service with repair documentation to claim eligible expenses.
