tried searching. couldn't find anything. i wanna tighten up the slop. i can't be the only one. any suggestions?

 

You probably have a bad bushing in the track system. I would just replace the track system. I had like 4 inches of slop on my tegs windshield wipers as a result of a broken plastic bushing. Replaced the bar with the bad bushing and problem solved.

 

hmm. i'll have to pull the unit apart and have a look. these parts are probably non serviceable though. unless someone on here can tell me otherwise...
