[QUOTE="crash2, post: 1367899, member: 15940"] So I ordered flanged bearings for my knuckles to get rid of that annoying slop and also fix my stripped out upper screw. Well being gung ho I went and pulled a dummy move and ordered the wrong ones. I ordered 3x6x3 when I needed bearings for 4mm screws. No big deal as it was like $13. Well one of those ideas hit me. When I built my steering (Dr. Frank style) I made some brass inserts for the rotation at the arms. Well they lasted short term before they got sloppy from being oblonged and the threads digging into them. [IMG]http://nw-wheelers.com/coppermine/albums/userpics/10002/swa-25.jpg[/IMG] Well here I have these 3mm flanged bearings--why not. Well I started by measuring the OD of the bearing and it was "very" close to 13/16". So I went and drilled the tie rod ends. [IMG]http://nw-wheelers.com/coppermine/albums/userpics/10002/swa-26.jpg[/IMG] Bearings [IMG]http://nw-wheelers.com/coppermine/albums/userpics/10002/swa-27.jpg[/IMG] Now here is where it got tricky. To keep the bearings in place I have to sandwich them with flanges out(flange on top/bottom of the arms) and with the combined thickness of the bearings they did not seat firmly against the foot of the tie rod. This would not give it lots of slop and easily cause the holes in the footings to become oblong. Well to correct this I made some shims and let me tell ya it took some guesswork to figure out how to drill these little things. [IMG]http://nw-wheelers.com/coppermine/albums/userpics/10002/swa-28.jpg[/IMG] To get the right amount of preload against the bearings I used both 4mm or 5mm washers drilled out to the same dia of the bearings.
