tailgate window crank install trouble.

while attempting to install new crank i somehow got one of the teflon wheels out of the track on one side..is there a secret to this, i cant get it back in track..passenger side..any help much appreciated, just got back on road after wireing harness replacement due to starter runaway problem...

Rick call me I'll walk you through it.
