I finally finished installation of Bob's step bushings.  They fit perfect, though they did require a little extra "push" to get in place, due to some small burrs in the bolt holes.  Also, I enlarged the holes in the steps to accept an AN4 bolt.  Hard to say definitively whether the extra tension of the 1/4" bolt or the bushing (or both) made the difference, but my steps are rock solid now.

I recently received a couple of beautifully machined bushings to preempt the wiggly step syndrome. A couple of observations:



* One of my steps wiggled ever so slightly. My theory why this is so is that the step holes weren't drilled perfectly perpendicular. Thus the AN3 bolt can't grip quite enough... and the step would exhibit more wiggle over time.

 

* Using machined bushings sounds good, but they may not fit right if holes are already drilled through the WD-1007 step and WD-1008 mounting bracket... unless your holes are just about perfect.



* If anyone hasn't yet drilled their step and wants a pair of "new" bushings, mine can be had for $23 including shipping ($33 otherwise). Contact me offline if interested.

 

* Replacing the AN-3 bolts with AN-4 bolts made a huge difference. Once the hardware was changed out there was no more step movement.



* Step access panels rock. Step inspection / tightening / replacement would be very difficult without having panels installed and I don't know how you'd do it otherwise. I used a couple of extra Vans wing type access panel kits for mine.

 

* Gottcha - Note that the bolt on page 30-4 installed with the head on top. Removing that bolt bolt after the fact requires lots of upwards clearance and it just so happens that there's a riveted on side panel in the way. Even with access panels removing the bolt is difficult. I ended up cutting mine off and installing the new -4 hardware with the bolt head on the bottom.

 

Now it's back to fiberglass work!

Jay

I just finished my steps two weeks ago.  Other than adding Bob’s step bushing, my were done per plans with an AN3 bolt.  I did have to sand a little off the bushings to get them to fit, but it wasn’t much.  My steps are rock solid.
