What's wrong?
The front independent suspension on the 2013-2014 E-One Cyclone Ii, Typhoon, and Quest emergency vehicles supports the front wheels while allowing them to move up and down over the road. Its ball joints are pivot points in that assembly. They let the wheels steer and move with the suspension while keeping the steering linkage connected and aligned.
On affected vehicles, the front suspension assembly uses Reyco Granning IFS24-S48Y10 components with ball joint connections that were not properly tightened to specification. A loose ball joint can develop more movement than designed. If the connection separates, the driver can lose steering control. The inspection checks the ball joint measurements, and any suspension outside specification needs repair and adjustment under the service bulletin.
The warning sign is unusual play or sloppiness in the steering system. If the steering feels loose, wanders, or does not respond normally, treat that as a sign the ball joints are coming loose.

What's the safety risk?

What should I do?
- Check your VIN to confirm your 2013-2014 E-One Cyclone Ii, Typhoon, or Quest is included in this recall.
- Contact a franchised E-One dealer to schedule the free front-suspension inspection and repair for loose ball joints.
- Bring the recall notice if E-One mailed one. If not, reference recall number 15V598 when you call.
- Drive only as needed until the repair is complete because separated ball joints can cause loss of steering control.
What happens at the repair
At the dealer, an E-One technician inspects the front independent suspension assemblies and repairs the assembly where the recall condition is found. The work centers on loose ball joints that need correction before separation affects steering control. The recall repair is free, including parts and labor. Owners can ask the service desk to confirm that the inspection and any required suspension repair are being handled under recall 15V598 before the vehicle is released.
