Don't know that you'd get noise from that unless the end of the boot was flopping around and a metal clamp was hitting the tie rod.  The rod itself should be pretty well anchored at each end.  Also I have not looked for that part alone but you could probably make one if you had to.  When I rebuilt my own rack using the Bus Depot kit I had no need for that part as mine were okay and I had already replaced a single boot earlier.  Good luck!

 Hey all,

I met a fellow van owner today and we were inspecting his suspension
because it's been making weird wobbling noises. The first thing I noticed
was his driver side steering rack boot was loose and appears to be missing
the grommet/bushing that the boot attaches to.

Thoughts?

Thanks!
