Coleman Thrust Nut

Replacement Thrust Nut for Coleman Whiffletree Assembly

Crank handle spinning but the roof not moving? In most Coleman and Fleetwood pop-up campers, this symptom points to a worn or stripped thrust nut. This component is designed as a wear item within the whiffletree assembly, and replacing it is often all that’s needed to restore proper lift function.

The thrust nut threads onto the main whiffletree drive rod. As you crank, it translates rotational motion into the linear movement that pulls or releases the lift cables at all four corners. By design, the nut’s softer material will wear out before the hardened steel drive rod — protecting the more expensive rod from damage. Once the nut is stripped, the crank handle will spin without moving the roof.

Key Features:

• Fixes Common Failure: Restores lift function when the crank spins but the roof does not move.
• Critical Lift System Part: Transfers motion from the threaded drive rod to the lift cables.
• Protective Design: Manufactured to wear before the steel drive rod, preventing costly damage.
• Exact Fit: Direct replacement for the standard Coleman/Fleetwood whiffletree assembly.

Pro Tip: When installing your new thrust nut, thoroughly clean and re-grease the drive rod threads. Proper lubrication reduces friction and extends the life of both the nut and the rod.
