Rear Differential Replacement

[skywise6854]

ok so i finnally got the Q back together this is my 92 Q45 active suspension

replaced motor transmission and rear diff

while installing the differential there is a breather nipple on top with a hose attached to it

where does that hose go or does it just hang there doing nothin or should i cut it short so its not hanging

also where can i get my drive shaft balanced my dad kinda dragged it across the concrete to move it out of the way not knowing it wasnt exactly the greatest idea.

Balancing a 2 piece shaft is more difficult because the shop has to rig a support in the center of the test lathe and do all sorts of time consumming tricks to decide how to deal with split phase oscillations.

Takes and expert and an engineer to do it perfectly..............most laugh and tell you it cannot be done...............also the Infiniti has foam inside to dampen noise and vibration.

Offering enough money can usually persuade.

The problem is the drive shaft can turn 6500+ rpm ~~ 140 mph [3rd gear].

so unless i feel it vibrating it shouldent be an issue?

or if it is then a replacement would probably be a better option then finding the right mech at the right price? no?

thank for the response .

still looking for some input on the hose coming off the rear differential carrier
