Hey guys, the Z had a rough day. One of my U joints on a half shaft busted and I am having the hardest time replacing it. Basically, the U joint where the driver side half shaft meets the wheel assembly wore out and the shaft separated from the U joint. Unfortunately, when the shaft separated, it banged itself loose, damaging the yoke that holds the U joint. I believe that I need to replace the whole shaft, since it's damaged, but I can't source one anywhere! Any ideas? Thanks!

Man was I off... I went back and tried to pinpoint the origin of the noise, and find that it is not the back at all, but the front brakes! I pull the wheel and do a quick visual, and find that the passenger caliper is very screwy. Somehow, the outer half (toward the wheel) is dragging on the rotor. So the caliper itself is grinding down the upper 1/4 inche of the rotor! Anyone else had this happen?

Here's a somewhat related question. Are there any potential problems that could arise from having the servo disconnected?

So, here's my situation... I have a 71Z, stock brake set-up, no idea how old the components are. My MasterVac is disconnected b/c lack of funds/credit to fix, so it's blocked off with caps until I can replace it. No brake problems to speak of. So the other day I have to make an emergency stop in traffic, I'd say from 30-35 mph to stop as fast as I could. At the first stoplight after that, a faint grinding comes from the rear passenger side. It's a little worse at the next stoplight, a good bit worse at the next, and at the fourth stop, its a horrible, loud metal on metal grinding that makes my heart stop, and I drive home (through the neighborhoods, thank god) with good downshifting and the e-brake. The grinding is only on one side, and only when the brakes are applied in motion. No noise when rolling, none when pressing the brakes sitting still. Stripped a shoe? Whacked out something else? What do you guys think? Thanks.
