844 lull issue

Not exactly sure how to describe it. But it seems on most 844 lulls that if you have the boom raised up and level the machine sometimes coming down something locks up and causes the machine to jerk. I think something in one of the pistons to level the machine gets locked up. That's best I can describe it. It seems to happen in alot of the ones I've used. So probably a lingering problem all around?
