General Car Chat / CV joint

Any way of telling without dismantling if the inner CV joint on a fwd car is shot? There is rotational noise and a vibration through the car noticeable at speeds above about 15 mph[could still be present at slower speed but not as noticeable]and seems to get slightly less on left hand bends.Could also I suppose be the support bearing on the offside drive shaft? Have tried driving in circles at low speeds listening for clicking and none present so don't think it's an outer CV joint.Car is a Volvo C70 petrol with a manual 'box.
-in a trickle of fluid from the bleed nipple and a brake pedal only just off the floor.Next visit to the car and the brake pedal went to the floor and no fluid would come out of the bleed nipple or the brake pipe at the caliper 
Pressure bleeder purchased which resulted in reservoir filling up and pressure forcing fluid back out of reservoir but none at caliper end >:(Master cylinder seems to be working correctly so either air is trapped in abs unit or the unit is fubar.I've yet to try reverse bleeding.If air is trapped in abs how do I get it out[assuming reverse bleeding doesn't do it]? If I need a replacement abs unit do all the numbers etc have to match and how do I make sure no air gets trapped in that when swapping them over? I have seen 3 used ones on e-bay,one from a 3.2 one from a 2.0 and one from a 2.2 diesel,while they look the same as mine[at least the 3.2 one and the diesel one do]the numbers and two big letters on the top are different.
