I've got the T2 with the 4 bike addon and all 4 of the ratchet aasemblies have stopped working. They slide up and down but don't ratchet anymore. I can still lock them down with the locks, I'm assuming the spring in the assembly is gunked up. I live in Portland and it's pretty wet around here, plus it's been on through the fall and into this winter. Has anybody had this problem? When I get my lazy butt around to it, I'm going to spray some DW40 into the ratchet assembly.
