Having trouble with my R32 gts4.. Has rb25 awd and the front wheels want to lock up. I took the awd fuse out and still the same thing.. Just wondering if any1 has had the same problem or ever herd of it before? Also all the brakes are fine and dont lock on

Does the 4wd light come on?

Have you tried removing the front shaft (transfer case to front diff)?

You'll need a 12mm ring spanner ground down a little around the outside of the ring to fit over the nuts so you don't round them off. Then spin the front wheels by hand.

I found it easier to get 2 12mm spanners and use the open end. You'll need to jack the car so all 4 wheels are off the ground, then just spin the shaft with your hand to get all 4 nuts and bolts.

But when the fronts or rears start locking up it sounds like a transfer/diff/elec problem. What size tyres are on it? Are they evenly worn? Have you done an ecu fault read? I don't know much about the subject, but most people have problems when the rolling diameter is different.

I was going to suggest front brakes but you said they're fine. Have you checked the diff and transfer oil?

Also do you have an awd button to lock it? Mine will shudder when it's turned on.

My S2 RS4S also shudders when the attessa engages. Before my clutch change I searched & searched SAU for the part # for power steering fluid special which is KLF30-0004 (the 4 determines the size of the container in litres) which Nissan only recommends for the use as the correct fluid for attessa actuation.

Nissan doesn't have a listing for that part #. The closest they could give me was Jap spec power steering fluid KLF50.

The old fluid that i bled out was a gold colour. Bled the new fluid right through, & shudder was still evident upon road test. I suspect there might be excess slack in the drive chain which causes the shudder, as grip to the front in the wet is perfect, so clutch packs are doing their job.

Nissan Matic D was used in the transfer case, without any change to the shudder effect.

Ideas anyone???

I was talking to my friend about this last year and he has the same problem. He changed diff oil and was worried the diffs were on their way out. The handbook states that when the attessa button is turned on it will lock into 50:50. So if you have LSD's it would make sense they're shuddering. You will notice it more on wider lower profile tyres.

How were you driving at the time it locked up steve? ie. full lock, straight, did it completely lock up? etc

I replaced all drivetrain fluids.

Front & rear diffs are running Castrol Limited Slip 90.

Tyres are a fraction wider, but the overall diameter is very close to stock.

My odometer is out 400m over a 5k distance. So I have to remember those ads on TV, 'wipe off 5' when I see a police car!

Obviously im waiting for the gurus (you guys) to reply, what is more frowned upon, remaking a thread that’s already been made in the past or replying to on old thread. Idk lol

I'd start a new thread with a clear explanation of your problem, rather than force prospective helpers to re-read an old thread and fish through whatever has been said in it to work out what your issue is.

Sweet I’ll find time to do that

      I am currently going this route. I am curious how much horse power you put behind the cut bell housing? Collins was telling me I am going to crack it and bluh bluh bluh. Because I didn’t buy the custom fly wheel from him. I am looking for somewhere around like 500 hp

      Thanks @PranK for the updated member status, much appreciated! 👍🏼 Now, about those pics… Unfortunately I could only find ones that I took in the dark. I was soon to discover that underneath it wasn’t in the best shape, but it was mine and that’s all I cared about at the time 😆

      A little PU bush story

      By GTSBoy · Posted

      Oh, and only having done this task yesterday, I've now driven the car ~60km since, and while it is hard to avoid placebo effect and confirmation bias, I reckon that some annoyances I had with the way the car has been behaving have improved. Which....kinda makes sense, I guess. If the bushes were really stiff and resisting rotation, they would have been contributing to the effective wheel rate. And if it was more so on one side (which it was, because one side was worse than the other) then.... you might imagine that the additional rate would be asymmetric, and potentially even different between compression and rebound. And so... the car has been twitchy at higher speeds - like freeway on ramps. It really shouldn't be. The wheel alignment is good and there are no (other) known problems elsewhere in the suspension. But at 90-100 on a long sweeping ramp, tiny steering wheel motions would make it feel like it wanted to rear steer. Quite nervous. At lower speeds it would heave about in a manner that it didn't use to. Didn't want to put power down, etc etc. Now...seems to behave better. Am going to have to concentrate on the various corners where it has exhibited weirdness, on the rare occasions when I can get a decent run at them without Methanial getting in the way in his D-Max/Ranger/LDV Van/etc.
