repairing ball joint

I have an 1985 diesel cub cadet (red). The ball joint has broken. It looks so easy to fix, but I'm a woman with very little experience. I was told to remove the cotter pin and loosen the lock nut. I cannot get the nut to loosen. Is this the only nut that needs to be loosen. Also, to loosen is it counter clockwise. I know some machines you turn the opposite. Help!

I am not sure it could be left hand threads but most likely it is just siezed up from bieng on there so long. Right tight, left loose is the easy way I remember. If the ball joint has come out the socket is most likely worn out. Sorry I almost forgot. Welcome to the Forum!..

Yes it is counterclockwise. You will need two wrenches to remove, one on top and one underneath. They can be very tight. When you get the nut off, count the number of revalutions it takes to remove the joint from the shaft. You will need to install the new one with the same number of revalutions. New ball joints come in both left and right hand threads. Make sure you get the correct one for you unit. If you need more info post back.

I am going to assume you are talking about a 782D? And by ball joint you mean tie rod end, because the front axles on these use king pins. Anyway, to replace the tie rod end it just unscrews lefty loosey off the tie rod. I put a diagram off of a parts website that you can look at. The tire rod end that you are replacing is number 4 and the tie rod that it is unscrewing off of is number 5.

I do not own a service manual for your tractor so I am making assumptions as to how it all is put together, the best I got was that parts diagram. If it is giving you a hard time getting it off, spray some penetrating oil (wd-40, pb blaster) in the tie rod end threads where it goes over the tire rod. Otherwise I would just say you are probably not using enough force, it is an old tractor that may have some corrosion that will make it not come off nicely. Another thing you can do i heat up the end of the tie rod end with a propane torch to facilitate getting it off.

Another thing you can do to get more leverage on the wrench is to interlock another wrench onto the end of the one you are using to make it twice as long, or you can put a pipe over it. If you were to round off the space where you put the wrench, use a pipe wrench. Hope this helps, let me know how you make out.

"It is a 782D. After I remove the carter pin, will that part slip off. I have tried to loosen the tie rod, but it seems that I am also loosening the other end of the tie rod. I guess I need to use two wrenches. You have gone to a lot of trouble for me and I appreciate it. Also thanks for the diagram. Would you happen to know the Parts # for this? That may be asking too much!"

Here is a parts manual for your unit. I'm working on finding a service manual for you.

Hey Rivets!
Good Job! Very helpful.
Crazy Lady
If you can get the tie rod out, take it to a repair shop and they should be able to get the end off and replace.
Shouldn't cost too much and might be faster than finding it yourself and repairing.

Thanks to all who helped Crazy Lady from Alabama. I will continue to work on the mower. May have to come back for more information. Have a great day!

After removing the cotter pin you will need to then remove the nut that is on the stud which the cotter pin goes through. In other words the cotter pin is there to make sure if that bolt ever comes loose it won't totally come off so you will never loose you're steering, but in your case the joint wore so much that the ball joint separated into two so that safety feature didn't help out much there. And also you are correct; you do need to use two wrenches in order to get the tie rod end off of the tire rod. I wish you luck, when you get the job done, you will feel very accomplished so keep going at it. Ask someone to give you a hand too, your neighbor or someone you know that is also mechanically inclined, im sure they'd be happy to give you a hand. You can buy the part here, its number 4, $13.

"Thanks so much for your help with repairing the ball joint. It took a long time to get the old one off (had to call someone stronger than myself); however, I installed the new one and it works great (but I will keep my fingers crossed). on the 782D do you know if you have the take the deck off to change the oil? I hope not, it can be a pain.

I would assume not. I've never had to on any mower. Do it in the driveway in case you make a mess like I usually do, oil cleans up well with rags or kitty litter. Easy job, shouldn't take more than 15 minutes. An old motor oil bottle with the side cut out makes a good low profile catch pan for tight spaces if need be. On the cheap chineese mowers, the drain is a pain and I usually end with it all on the ground haha. But yours should not be a problem.
