I have taken apart many EZ Steer boxes that have been provided to me by people who have changed over to our F100 steering boxes. Most of them had a very rough thrust surface facing (as Ken said above) and other issues. Even the adjustment system on them leaves a lot of room for improvement. The EZ Steer adjustment system is done with thrust washers (wavy washers) and an adjustment screw that pushes only. A F100 steering box adjustment system does not use a thrust set-up but rather the adjusting screw pushes and pulls. I have tried to fix a couple of the EZ Steer boxes but the fix is somewhat expensive. I do take some EZ Steer boxes in on trade towards the purchase of one of our boxes as some of the internal parts are the same as that of the F100 box. This depends on the condition and wear of the EZ Steer box.
If you want advise on how to adjust one, then call me and I will walk you thru the process. No guarantee that the adjustment will work as conditions inside will determine that.
