Steering Cross Tube Assembly - Mack Pinnacle CXU CHU Greaseable Tie Rod - 21639955 24426460 7QH45 463.DS9881

Take the slop out of the steering with this heavy-duty Steering Cross Tube Assembly distributed by FleetPro Parts & Tires. It is the complete linkage that replaces a worn cross tube on the Mack Pinnacle, CXU and CHU — and once the ball studs in that linkage go loose, the truck tells you about it: play in the steering wheel, wander that never settles, and an alignment that will not hold no matter how many times it gets set. Manufactured by Automann to Fleet Standard specifications, this assembly arrives with greaseable joints and is ready to install. We stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, diesel repair shops, and owner-operators nationwide.

Tight Steering Restored: The Mack Steering Cross Tube Advantage

This is a complete assembly, not a bare bar. Tube 464.218 comes fitted with the 462.ES423L and 462.ES423R ends, so there is nothing to source separately and no guessing whether the pieces sitting on the shelf belong together. The joints are greaseable, which is what lets a steering joint be maintained on the truck instead of being run to failure and thrown away. At 28 lbs and shipping as a 72 x 6 x 4 in package, this is the full-length linkage, ready to go straight under the truck.

At FleetPro Parts & Tires, we know a steering job is only right when the part is right. This is a brand-new assembly backed by a 1-Year FleetPro Warranty, and it is the direct replacement for the highly searched industry numbers Mack 21639955, 24426460 and 7QH45. Set the steering wheel center and check the alignment once the linkage is in — a fresh cross tube deserves a fresh alignment.
