I have a JD 855, with steering issues. Anyone have any thoughts on what it could be.

Additional information will be helpful. Is the steering imprecise, loose & sloppy, tight and hard to turn the wheel? Is it noisy indicating a possible hydraulic problem? :dunno:

The more information you provide the more advice you will receive. :good2:

which model of 855? early or late...Fuel tank location will help determine this.

2wd or 4x4...?

On the 4x4 the tie rod can drag on the front housing if it has been bent forward.

check the rod on the power steering cylinder for staightness/rust.....assumeing it has PS.

Is your hydralic fluid at the correct level?

1 check that the tie rod...rod that connects L to R wheel is strait and not binding on front axle.
2 Wiggle steering wheel L/R...look for slop on tie rod ends and hydro clyinder ends connected to tie rod and tractor frame.
3 look for leaks at hydro cyl. and lines going to it.

My guess is the steering box/orbital unit is kaput.

If possible..Get front axle off the ground( this will be tricky ) if your front loader is working you can lift front tires with it...then check how it operates L to R.

I see you show no loader in pics...you will have to lift each side of front axle and block it up as it pivots in the middle.

Your hydro oil level is good???.....sounded like it but double check.

I don't have the loader for it. I wish I did,lol. I will look at the things that you suggested. Is rebuilding that steering box difficult?

I also noticed that when I add weight with the 3 point it was easier to steer. Just thought I would mention that, I dont know if that will help at all.
