My 8345 had some lube problems on the steering spindles.  I drilled the right one from the gear housing into the center of the spindle housing.  I drilled it at an angle so that oil on the axle gear would push oil through the hole into the spindle above the thrust bearing and also onto the spring.  It leaks on the floor, but turns great with the loader.   Also, make sure you have weights on the rear wheels or fluid in the tires.  I use mine a lot for loading hay.  I have a bale spike on the back and  always keep a bale on the spike before picking one up wit h the loader.  The more weight behind the rear axle, the less on the front axle.  it is literally a balancing act!

Hello, not familiar with your tractor but how about shims or collar/pipe stops to prevent front-end bottom out & binding under load?

Re. lube etc, in case they help, see attached five front-end maintenance screenshots from an MTZ 821-921 manual:

Front 4x4 Axle Lubrication
« Reply #1 on: June 18, 2018, 11:21:53 AM »
Hello everybody,
I have a UMZ 8244 which is close to a 800 with a 595 Allied loader and has the arched type 4x4 axle with final drive hubs. I've been having problems with the steering locking up with any load on the loader. I thought that a trust bearing or spring might have been broken. I just dropped the hub off the axle drop tube which was a major job because of rust on the drop tube. I didn't see anything wrong other than the rust on the drop tube and the collar being dirty and binding. My question is how is the drop tube lubricated? I had the hub filled with oil and the axle is also filled with oil but I see no way that the drop tube gets lubricated. With the loader mounted the springs collapse and the hub rotates up against the collar which binds against the hub. Are there heavier springs available? Any help will be appreciated.
