4wd Not Working

[jaygtr]

Hi I have recently bought an r32 gtr. The 4wd doesnt work, but the front torque meter is still working and the 4wd light isn,t on indicating that there is nothing wrong. Can anyone help me out?

So what makes you think the 4wd is not working then ??

The R32 will slide the back out when doing ..err... spirited driving .

If you are expecting it to handle like a WRX , ie. fairly neutral then you will be mistaken.

It will also spin the rear tyre a bit then the gauge should shoot up as the front engages on a savage launch.

If it is very slow to rise or only rises a bit , it may need bleeding or at worst the clutch packs may be gone in the transfer case.

Cheers

Jay, As Ken points out the GTR isn't a constant 4WD system, it's active, and transfers torque to the front wheel when the rear starts slipping. If in doubt take it to one of the import workshops and I'm sure they'll tell you if it's working

ATTESSA is a reactive system, so it is only ever going to try & catch up with what you are doing.

It can be air in the system, but it also (Don't want to alarm you) can be due to wear in the ATTESSA clutch plates. When these gets tired the system still apportions torque (or tries to) by using the same clamping pressure as before, but it no longer works properly because the wet clutches slip more than they are supposed to.

Best bet is to get the system bled, then check it by a back to back test with a known good unit.

Thanks for the replys. I know that the gtr 4wd isn,t constent like a wrx but when i try to do a launch at 5000 rpm it just spins the back tires, also when the car gets full boost in second gear at 5000 rpm it spins the tires all the way to 7000rpm. I've noticed as i have been driving when it usally spins in second gear at 5000rpm it got full traction 4 times. So do you guy's think it the ATTESSA clutch plates?

It could be the clutch plates, or the system may need bleeding. Best to take it to a good workshop to get the system bled, if that doesn't work then you may need new clutch plates, but that won't be cheap.

How much do u think it may cost??

Best to ring one of the Skyline workshops like HyperDrive or Xspeed, they should both be able to give you a price.

this thread reminds me that my 4wd aint worked since i had my gtr imported lol my warning lights are on all the time and nothing reads on the front torque guage and yes i have checked the fuses and they are ok

[jaygtr]

Are you thinking of getting yours fixed? When i bought mine i had xspeed check the car but they never mentioned that the 4wd wasn,t working. I was pissed when i found out when it was being dyno tuned.

[gazza750]

i willfix it eventually but its fun driving the gtr in 2wd lol

The two issues (Gazza's & gaygtr's) are diferent.

Gazza - yours sounds for all the world like an electronic problems - in which case the ATTESSA module under the parcel shelf should be blinking away trying to tell you what is wrong.

JayGT-R's is, like has been said, either a bleed issue in the attessa or worn clutch packs. Take it to someone who knows the systems & just as importantly knows what to expect from the ATTESSA system in terms of performance.

jay: is this the blue GTR from busselton?

if so, the seller was aware that it was only running 2wd

Yes how did u know?

The guy says he wasn,t aware of the problem.

yeah it is flashing i will get around to getting it seen to eventually

Gazza your GTR may be the G sensor the other sounds like you could bet on it being a bleed but it should have been picked up in a pre purchase checkup.Top racing can bleed it also if your south of river.

get some pics up!!! this thing sounded like it had some gear on it. have you found out what turbos are down there?

i spoke to the owner for around half an hour on the phone cause i was going to drive down there to see it. i asked him about the faults on the car (to save me driving 3 hours and being pissed off) and the first thing he said that it was only running the rear wheels. he even said that he had got quotes from a workshop in bunbury to fix. wasnt aware? pfff no way!

seemed to be going for a good price too
