I have a 455 New Holland loader

Need to know what causes it to jerk while starting in low gear it also squeals when turning. Fluid is fine, new filters could this be a linkage problem and if so how do you fix it. THANK YOU:confused2:

When you say it jerks in low, it jumps or lurches forward but not reverse? Is throttle at idle, ie: 750-900 rpm?
Steering is squeeling while just turning or when it is turned against lock? Squeeling from pump? All the time?
