Hzj75 vibration

[toy88]

Hello all..
I have a 1998 hzj75 trayback, I was on my way back from a fishing trip the other day & a really bad vibration had started under acceleration, I stopped & there was heaps of oil pissing out of the pinion seal but no movement what so ever with the pinion shaft, or uni joint? & it only does it at certain speeds under acceleration? What could this be??? I don't really want to take my diff centre out until I have had a few ideas thrown at me so I can narrow it down?

2nd problem is my aircon trips out as soon as you go over 90kph & the volts drop? What could that be?

Any info or help would be greatly appreciated cheers

Drove off a balancing weight of the tire ?

All the ballancing weights are on, I double checked, it only does it under load, so when you accellerate! You put ya foot on the clutch & it goes away?

Pinion preload?? Pinion might be loaded when you checked it. I lost preload on my pinion shaft in my rear diff in my 80 series a couple of years ago, lots of vibration and noise but more when coasting I had nothing under acceleration or deceleration. Make sure u don't run your diff dry.
