Ford 2000 wont steer

Hello, first post here.
I mainly work on heavy equipment, but got a call to look at a Ford 2000 that wont turn left. Only turns right. From reading, and searching on here, it appears its the upper thrust bearing. Is it a pretty tough job? Any tips?
I havent been into one, so have no idea what type bearing it is. Is it a needle type or roller? I did see mention of measuring and shimming do you just set the base down without gasket snd measure the gap?
Thanks

Power steering or manual?

Good question. It was an older lady that called, said her husband cant hear on the phone. I asked if it was power steering, and could hear her hollering at him asking But from the what I could gather its manual. Im hoping to finish up a job Im doing tomorrow and get out there Tuesday to look at it. Ive worked on a few Fords, but cant recall ever working on the steering box.

It sounds like the upper thrust bearing in
the column. Oil leakage from the steering
sector shafts let the oil level drop and
that upper bearing gets dry. Pretty common
on manual ones. Less common on power
steering boxes as the upper bearing is
lubed by the PS fluid.
Its is a very simple mechanism and easy to
repair. Parts not expensive. Hard part is
you have to remove much of the hood,
wiring, etc to get at the column.
By the way, Ford built two completely
different 2000s. A 1962-64 four cylinder
model and a 1965-75 three cylinder model.
For many things it is important that you
tell us which model you have but in this
case the problem and fix are the same.

All agreed with UltraD. The bearing replacement is easy but the getting to it eats up the time.

Thank yall for the replys. What is involved in the shimming I read about? And are the shims just gaskets?

Shim for zero end play or slight preload and that should be good enough for a steering box. Shims can be metal or paper gaskets, doesn't matter.

The shims are where the steering column shaft bolts to the steering gear casting. There will probably be a few already there that you can use to make more
copies, or you can buy a pack of them when you order bearings. Sometimes the ones present are sufficient, or you may have to add a few, or even subtract some.
Set to zero lash- no discernable play up and down and no obvious friction drag on the bearings. Before you hook the steering arms to the tie rods you should be
able to spin the steering wheel from lock to lock with a quick flick of the wheel. Fill it full of gear lube, or Corn Head grease and go.

As said by others its a straightforward job, its just a bit of work actually getting to the steering gear!

Another thing to watch out for is Mission Creep. I recently fell into that trap on a Jubilee with NASCAR Syndrome (only turns to the left) and once I got the
sheet-metal off, I ended up replacing a few cage nuts, replacing/rewiring the electrical system and fitting a new gas tank. When it was finished, the hood and
cowl no longer rattle, the sediment bowl and carburetor are gunk-free, the 6 volt generator actually charges, and, oh yeah, you no longer have to dismount the
tractor, grab the front tires and pull them to the right when you want to go in that direction.
