So today I tackled the cab door wind lance or cab weather strip. I heard it's a real pain in the donkey's rear, but found a cool idea. I made a little tool that was similar to the rubber profile that I could slide down the channel. It will open up the channel and make sure it is clear. Then I started at the back top and worked sliding the rubber forward using WD40 as lube. Then I trimmed the back part to length and slid it straight down. All in it took 3 hrs (tool and both doors)
