its hard to explain but ill try my best.

on the end of my drive shaft (gearbox end) the joint on the end with the splines, well the outer casing comes away from the bearing carier and you can move it down the shaft away from the gear box about 6 inches, it wont go any further and wen u turn it the whole shaft still turns

is it fuked or do RS's have sum different type of joint

im asking because ive refit the shaft into the box and no leaks but after a short drive i gain a small leak from what looks like the driveshaft seal, it cant be the seal as its a new box from cts
