JD 7000 planting units - gauge wheel bearing loose in ar

Most of the John Deere maximerge planting units I have worked on have the roll pin holding the gauge wheel bearing in the gauge wheel arm. I have converted two planters over to the bolt on gauge wheel. Started work on another John Deere planter with the bearing that has a groove in the shaft that a set screw set in and holds the bearing in the gauge wheel arm. I have not worked on the set screw type before. What I noticed immediately is that all of the short little stubs that stick out of the bearing wobble in the gauge wheel arm. They are loose. I never had that with the original roll pin type. Is the gauge wheel arm or the shaft on the bearing worn out or is that the way they are? The actual bearings seem good yet - the problem just lies in where the bearing attaches to the arm. I don't know if sleeve locker would help take up the slack? Hate to replace them as the other end that attaches to the planting unit is the updated quick adjust style. Appreciate any advice.
 
Our oldest son has been running a 7000 for several years planting corn and soybeans.
After all the trouble he is having this year, he says he will buy a different planter before next year.
He maintains it well, but something is always breaking.
 
Maybe the set screw is designed to reduce the wobble as it is tightened up....otherwise, I would insert a sleeve and a bolt or roll pin like the older style has.

they should not be loose in the tube but not tight either. Just a reasonable fit to slide in and out some thing that wobbles is to loose I would think. I't been over 30 years since I worked on a 7000 planter and was not impressed with it. Not all that impressed with working on our White either. It plants good though.
