Kubota L4701 Hydraulic issues

[Jax3rd]

So I’m I’m having an issue with my Kubota L4701 when I start it the loader and 3 point goes up and down fine but after about 5-10mins it struggle to lift up goes down fine but when I try to lift up it won’t move for a minute and go up about a foot and continues has hydraulic oil their are no leaked bled lines to see if their was air in the lines still continues to struggle the hydraulic pump does make a whining sound it’s my only implication that need to be replaced anyone else have any info or insight on this matter would be greatly appreciated thanks. Also forgot to mention the steering goes out I have to continuously turn the steering wheel and it catch and turn the wheels ever so slightly sometimes will have to turn it completely 5 times for it to catch

Have you checked the fluid level?
Have you done a filter and fluid change?

Another slight possibility, move the three point control to about 1/2 way and see what you get.

If that fixes your issue you need to adjust the feedback linkage.
