For many years in my 2001 suburb I cursed and cursed my rear sunroof. Finally replaced the old ones with these and they work great. The big heavy door swings open and goes to bed. The closing resistance might be too much for little people or kids, but I actually prefer it because my old ones caused serious trust issues. Ease of installation. Do not remove the metal brackets from the new one as if removing the old ones. Once the old racks are removed, they stand up straight away. It helps if someone holds the door open while you remove the old ones.
