Hex Cap Screw 3/​​8-16 x 1.​​25

looked up the diagram provided by your ereplacement site, parts were loose already and all I had to do was put it back together.

1. Removed lawn mower deck and jacked up the lawn tractor. Diagnose the source of the problem of the steering wanting to turn only one way. The Hex Flange bearing was slipping.
2. Found a illustrated parts breakdown of my make and model Cub Cadet.
3. Found the breakdown of the steering, compared it to the defective parts on the Cub Cadet and order the needed parts from eReplacementParts.com.
4. When parts were received I removed the Flange Lock Nut,​ 7/​16-20 with the 7/16 socket and ratchet, pried off the Steering Pinion Gear, with a flat head screwdriver.
5. The worn part still wasn't accessible so I had to take loose the drag links (left and right hand) by taking loose the locking flanged nuts. using socket and ratchet set.
6. Had to remove the Steering Support Bracket (6 self tapping screws): tools 5/16 socket, ratchet, 6" extension.
7. Pulled bracket down off of the steering shaft, washer and worn hex flanged bearing now accessible. with the steering support bracket down I tighten or replaced any loose or worn parts. Checked the hex cutout in the support bracket for ware, was acceptable. Centered the steering wheel.
8. Placed the hex flanged bearing in placed, placed washer on steering shaft, hex bearing, bracket, another washer, pushing the steering bracket in place on the steering shaft, replaced the 6 self tapping screws, center steering gear on steering plate ( used stubby Phillip screwdriver ), replaced the pinion steering gear and self locking nut.
9. Align front wheels, Adjust and reinstall the drag links (left and right hand).
