Back Hoe supports

[DIRTCUTTER]

I have a CK30 with FEL and a 2375 Kioti back hoe. I seem to be always tightening up the two supports that go from the backhoe to the sub frame. These supports are angled.I have used locktite;new lock washers; and replaced the bolts and nuts. Short of welding I did not find a answer.I know there are a few of these bh's out there.Thank you for any idea's.

Same problem, same setup. I welded no more problem
