Bad noises & brake lines really do swell up....

I recently purchased 2574356. After doing minimal work to make her road worthy I made the hour+ drive (75 miles) to the storage unit where it will sit for an unknown amount of time. While driving the car started making a horrid squealing noise. Not a wheel bearing, this was directly related to the driveline. I can't tell if it's in the diff or maybe the output shaft? It occurs at neutral throttle and slight accel. Not on decel or hard accel. On new or tight cars there is no give in the transition between acceleration and decel but on older cars, because of wear and tear, there is certanly room and this is where the noise occurs. This squealing noise that sounds almost like a bandsaw cutting a piece of 1/4" alluminum sheet, happens at neutral throttle, when there is no load on the driveshaft... if that makes sense.

Can anyone tell me what exactly that is?

I changed the oil, points, plugs, cap, rotor, wires, coolant, trans & diff fluid, bled the brakes, replaced front flex lines, etc. BUT I didn't replace the rear lines. The left rear bled well so I left it. The R.R. bled slow and only a trickle but I went with it because it felt OK and the parking brake engaged. When I arrived at the storage unit the RR wheel was smoking. I'm lucky I didn't lose the RR line on the road. They really do swell up so if you bleed the lines and you don't get a good squirt coming out take the time to replace your lines. When I cut my forward flex lines they didn't even drip. You couldn't even stick a paperclip up the lines because they had swolen that much. Just a reminder to flush your lines often and if you see cracks in the flex lines REPLACE THEM - they are cheaper than body work or worse....

your noise ?..............

exhaust system touching the body someplace - or the rear subframe

bad center drive shaft bearing

bad shifter platform mounts - bottom of shifter rubbing on drive shaft

You know what CD... You're right (bet you love hearing that) It is the shift tower support because there's a little shiny ring around the driveshaft just aft of the guibo...

I was worried that it was the output shaft or the diff....
