3020 wheel wobble

[Anonymous-0]

its not the wheel bearings or tie rod ends , i think its the shaft that goes from where the wheel hooks on and goes up to the stearing ( has a big bolt on top) is there any adjustment on it , or any way to tighten it up some so it dont wobble
Thanks

probably need a new steering arm due to worn splines.

New spindle bushings, but if the spindle is worn too might need both spindle and bushings.

Probably the male (spindle)and female (steering arm) splines are worn. How "particular" are you in having it done right or it looking right? You can put a large washer on top.......one with a big-enough hole to go over the spindle......which will allow the spindle to pull further into the arm or some thin metal......like an old tobacco can....can be used as 'filler' to make spindle splines larger.

That sounds exactly like what the problem is guys. thanks alot for the replys. Now if i can get the bolt out, tried tonight and that sucker is tight. Will it last a couple months if i do the make shift repair? I bet jd will stick it to a feller for them spindles! oh well
Thanks again

You can get those spindles a lot cheaper from nnalert or "tractor parts asap" (on the web).

In addition to the spindles, you will need the steering arms as well, because if the wear is on the splines on the top of the spindle, the steering arms will be worn too.

These 4 parts will run you $300.

I think we may be having this same problem on our 2840. So please tell me, how does one go about checking the splines to see if they are worn, or too worn and need replacing?

Thanks

On my 4020 I had a machine shop mill down (up) the bottom side of the steering arm so it would pull on further with the bolt. Like below, I added another washer to push on the arm but go over the splines. Worked and is still working.

Any of the mentioned repairs can be considered permanent; they'll last indefinitely. I've also taken an (9 inch) angle head grinder to the top of the knee, so the spindle will stick through further.........

I repair those worn splines with Devcon epoxy metal and have had real good luck. It is simalar to JB weld only stronger. Deere had the stuff to fix worn spindle splines on a industrial tractor or to repair worn taper wheel hubs on a 440 skidder.

What Rob said is correct, or most of the time. When one part really wears out, others start to over compensate and they wear out [faster] too.

You need to check out your entire steering system where anything moves or is required to move to make the tractor turn/steer. If not, then the other worn parts could starting wearing out the part you just repaired. I replaced the spline/coupling on my tractor, but had to take the "slop" out of the upper steering parts as well to achieve full success...as the saying goes, "you can pay it now or pay more later"..since she is open, you might as well do it all now/

I was able to put a NEW aftermarket steering arm on the 4020 and get it to stay tight.

I fixed my 4020 about 20 years ago by just getting a thick washer and putting it on top of the steering arm, the inside diameter of washer has to be large enough so the spindle can go through it when you tighten the bolt.
