R32 Gtr Has Constant AWD

Hi guys, 4WD light is on but my car is constantly awd, I pulled out both awd fuses and it was still sending power to the front wheels, (I had the car on a hoist). I have found that the awd bleeder connector in the driver side kick panel is there but there is no plug or wires coming from the boot into it. There is also a small loom cut before the pump in the boot. I noticed when the car was on the hoist on the front right wheel was spinning the same speed as the rears but the front left was stopped. Also when I took the car around the shop it would shutter when turning and if you accelerated a little and backed off it would clunk harshly.
Any ideas?

Wow that is a strange one. The on front wheel spinning thing is because of the open front diff.

sounds like something has almost shorted, faulty electrics keeping the awd engaged? doubtful the mechanical side would do that?

It's definitely electrical, the loom to bleed is cut, there's a loom in the boot that's cut just before the fluid reservoir, also there is a grey 2 pin plug that has been cut underneath the car where the motor is. i had to bleed the system by turning the car on and off a couple of times. I will get some more photos tomorrow

Do these looms join up by any chance?

[Giaccovitch]

That last loom with the red plug comes from the awd pump

Can anyone tell me where any of those looms are supposed to go? Would be much appreciated

[Giaccovitch]

By the way I found out the main source of clunking was because my rear subframe bushes have collapsed

If i jack my car up all 4 wheels off the ground and flick the switch on my 4wd controller to 2wd (same as pulling the fuse) I still get some front wheel rotation however nothing on the torque split gauge and you can grab the front wheels and hold them stationary. flick the switch back to 4wd however and as soon as the clutch it let out torque gauge will show some reading and front wheels won't let themselves be stopped.

My Guess is your 4wd isn't engaging at all, hence the light being on on the dash.

[Giaccovitch]

On the hoist you can't stop the front wheel so I think it is working, I haven't checked the torque gauge though

[Giaccovitch]

Fixed the light on the dash, forgot to put the speed sensors on lmao. Still get very hard shuddering on full lock turning as if the car has a locked diff, have tried new oil and additive. Still not sure

[Giaccovitch]

Can any tell me where the cut wires I have shown are meant to go? Would be much appreciated thanks

[Giaccovitch]

Bump..

[Giaccovitch]

Does anybody have a diagram or photos anywhere?

Cool thanks mate, I remember a black one next to the green fuel pump relay, I’ll have a look for the other one
