Is the sliding door on your Ford Transit Connect van getting hard to open, making grinding noises, or not rolling smoothly? The middle roller on the track is probably worn out. This is the replacement part for the LEFT-HAND SIDE sliding door on vans equipped with the dual side load doors (the ones that have two sliding doors, one on each side). It's a direct aftermarket replacement for the OEM Ford part numbers DT1Z-9926801-A and DT1Z-9926801-C. It fits Ford Transit Connect cargo and passenger vans from 2014 all the way through 2023, with either the 2.0L or 2.5L engine. Replacing this roller can make a huge difference, restoring that smooth, easy glide when you open and close the door. It's a crucial wear part. We highly recommend getting a professional mechanic to install it, as aligning sliding doors can be tricky. But if you're handy and have the right tools, it's a doable job that will save you a ton on a dealer repair. Keep your van's functionality at 100% with this essential replacement part.
