The tracks don't need lube. The rollers are supposed to roll. Check your door springs.

Springs seem ok, but what should I be looking for they seem to be equal lenght on both sides when not under tension

You should be able to tell if one is broken. Check that gear.

I have now replaces all hinges ( a few of them were bent ) all of the rollers, all of the wheels for the cables and the springs, but the door still is not closing all the way to the ground on the right side. Any further Ideas, or should I just call someone to come and look at it? THanks
