hey, my doors on my 1978 clunk really loud when I shut them, they dont close when I lock it and try to close the door from the outside, it latches but doesnt shut all the way, i have to hit it with my hip to shut completely. (it closes fine if I dont lock it until i use the key after its shut.) They make a very loud clunking and sqeaking noise at the hinges. Anyone know of a good lube that works to take that problem away? Also the linkage for the key lock mechanism is really difficult to turn with the key, can that be lubed somewhere also? Because its hard to turn, the stupid ends have worn out on the tumbler (?) and now the passenger side key lock doesnt work at all.
