Overnight the steering in my telehandler locks up solid in freezing weather. I have to tug on the steering wheel back and forth until it eventually frees up a little bit at a time. It started last winter so I changed the hydraulic fluid out thinking that may be the problem but although it helped a tiny bit it still locks up solid like the steering wheel is bolted down! Once I do get it freed up the steering will randomly lock up until after a few full turns of the steering wheel, the rest of the day it seems fine . I called my repair shop but they are no help. Any suggestions as to what might be the problem? It does it in all steering modes and the rest of the hydraulics work fine.

Could be some moisture in the orbital. You might look into a magnetic engine block heater. If you have a place to plug the engine in you should be able to plug that in as well. Put it on the steering orbital under the dash. If it's not froze up the next morning you know that's where your moisture is at. If it's still froze up you know that's not the issue.
If you have a freezing issue those magnetic block heaters are great for diagnosing it. Move it from valve to valve untill you find the right one. Saves some time taking valves apart looking for moisture.

I have a few suggestions, have you checked your stand by pressure? If its low It could have hard steering effect. Also do you have antifreeze hydraulic oil in the unit? especially being up north.
