LSD & pipes (archive)

Which way did the other wheel turn? If it's an LSD (that ain't completely burnt out, that is), the other wheel will turn the same direction and the same amount, without any lag. A better test would be to have the car in park or in gear and attempt to turn a wheel; if non-LSD, the other wheel will turn the opposite direction.

Observe the origin and destination of those pipes -- the hydraulic PS & PB system. The lines make a loop just behind the kidney grill, forming a rudimentary cooling circuit for the hydraulics.

Hi Ya'll
I had the car up for a PS filter change. If I rotated one of the rear wheels, the drive shaft spun and the other tire turned slower after a little rotation of the wheel I turned. This means I have Limited Slip, right?
I have two lines running fore/aft inboard of the battery. They are metal and I have no idea what they carry. Help is appreciated.
I replaced the PS Filter because my Brake light comes on and blinks for a little bit after I start the car. It still does it. Now after pumping that pedal like a big dawg, the resivor level rose over an inch. A good indication the bomb had oil stored in it. So if the bomb is good, and the light goes on a bit after starting, is there something else I should try? Switches for instance.
The board has been very helpful in sovling cruise control problems, brake problems and the external temp sensor location. Keep up the good work, er help.
