2005 Phaeton, 40 foot, VIN# 4UZAAHDC85CV06116 My driver's side front slide out is creeping out while driving down the road to about 4 inches at the bottom, the top remains closed. I recently, a week ago, had repair work done on the Teflon mat (became detached and had to be reattached) under the slide out. Also, two days ago the bolt that acts as a shear pin on the drive mechanism on the forward portion of the slide out broke and I replaced it. There is also one on the rear part of the slide out drive mechanism that looks good. How do I fix this problem?
