Jeff Z. · Feb 1, 2010

Lack of regular greasing of the king pins.

...a pretty Cub Cadet rolling by?

Seriously, could be any part of the steering mechanism. I recommend you take some time and perform some logical troubleshooting and figure out exactly where the problem is.

First, jack up the front end from the middle. Does it steer easy now? If so, your tires are flat or you have a loader on the tractor. Inflate the tires, or remove the loader, or learn to live with it.

Next disconnect the tie rods. Does it steer easy now? If so the problem is in the king pins, as stated. You will probably need to remove the spindles and clean them up to get things moving.

If it still steers hard with the front end off the ground and the tie rods disconnected the problem is in the gearbox. Probably worn bushings causing the gears to bind up, or poor maintenance and lack of lubrication in the gearbox. If it's lack of lubrication, again, you'll have to take it apart and clean up the shafts and bushings with some super-fine abrasive.

Alot of times because of lack of regular greasing of the king pins old grease and dirt combine and form a thick cake. Sometimes when you grease them and see some grease coming out the ends they are not getting grease all the way up and down and all around the king pin.
I find after removing the pins and cleaning them up good with a wire brush on an electric grinder and installing new bushings with Amsoil Off Road Grease they work great.

I believe the steering on a Cub is like my A, and, if so, mine got stiff when it sat out alot in the rain.
I discovered water in the steering gear box that caused rusting inside. Once I cleaned it up and got th water out and kept it out, it steers fine. I did all the things mentioned by others here first and finally pulled the plugs on the gear box and red water ran out, telling me I had an issue to deal with. hope this helps.

Not sure if you have already taken anything apart, but the steering shaft bushing, where the shaft enters the bolster, has a clearance gasket in it that adjusts endplay of the steering shaft. Loosen the two cap screws...if it steers easily afterwards, you need an additional gasket. If you haven't had that apart though, it is unlikely to be the problem. Insufficient clearance will essentially clamp the shaft in position.

I would jack the front up and see if the spindles will take grease. By having the load off the grease should come out the bottom. You mite want to unhook the steering arem so you can work them while greasing. Then check the gearbox as it mite need rebuilding.
