Re: Steering problems on troybilt bronco
The steering problem of the Bronco not making a right turn is normally the results of the Hex Bearing Flange wearing out. The replacement part with shipping is around $10.00. To fix this problem is not really difficult, but it is a knuckle buster due to lack of clearance when removing and replacing some of the parts. Remove the two metal hood sides of the hood assembly and then drain and remove the gas tank.
Now, get on the ground, on your back and remove the lock nut from the bottom of the steering shaft. A flashlight or shop light helps. Above the lock nut you will see a metal gear and above that is a metal washer. It may be necessary to drop the mower deck to get to this nut. If you can remove it without removing the mower deck, do so. Removing and reinstalling the deck is frustrating and time consuming. After you have removed the lock nut and the metal gear, lift the steering shaft about an inch and then remove the metal washer that was above the metal gear.
Now stand up and lift the steering shaft to a point above the round hole in the frame and move the bottom of the steering shaft to the side a few inches so it is out of your way. Using a flashlight, look into the round hold and you should see the worn out Hex Bearing Flange. Reach into the hole and pull out the old Hex Bearing Flange. It is possible that the old flange totally disintegrated and is no longer there. Place a heavy coating on grease on the new part and place it into the hold. Note that the HEX section of the bearing flange goes down into hex shaped hole in the lower frame. Coat the bottom section of the steering column with grease and reinstall. Now on your back again and replace the washer, gear and lock nut. You may have to slightly lift the steering shaft to get the washer in first. Apply a heavy application of grease on the gear. Make sure the steering now works properly, replace the gas tank and replace the hood side panels.
