Hello all well I'm a newby who is after some help for a new project I'm building. :blush:

I building a new comp spec 4wd which will have 4 wheel steer. I've been told there where some Skylines and possibly other Nissan's that had rear steer. I'm just wondering if anyone can help me out with what makes and models have this as factory as I'm looking for a power steering pump out of one as it makes doing this mod a little easier. It would also make finding what I'm looking for easier on eBay. BTW it's going in a Nissan patrol so I'm not jumping ship. :)

Any help would be greatly appreciated.

Cheers Mick.

it worked by deflecting the hubs via a hydraulic rack/ram to simultaneously steer the rear wheels in either direction depending on speed (counter at low-speed and in sync with the fronts at high). was really just a marketing gimmick though- every keen driver just fits a hicas canceller bar/kit

would be of largely negligible benefit if your aim is to make your fourby more manouverable in the bush, and would be monstrously difficult to adapt seeing as you'd need to use an axle setup on the back with steerable hubs (apart from everything else)

now we are talking....sounds like a good project.

there are 2 basic types of rear steer on skylines etc.

32 series ran hydraulic rear steer using a big ram between the rear hubs driven by pressure from a 2 stage power steer pump at the front.

later 33/34/35 run electric rear steer.

But in any case they only turn a few o which in unlikely to give you what you need. what sort of competition?

and to elabourate....the rear hubs only turn on their bushes as well (multilink setup with normal cylindrical bushes). front obviously has swivelling joint at the top of the hub and ball joint at the lower control arm to allow proper range of movement

Thanks for the quick response fellas. :blush:

It's a very common mod in our sport and the pump will need some modding but it gives us a pump that can handle the 4 wheel steer. I'll be getting around the 25 degrees of steering in the rear and about 30 degrees in the front. Both will be full hydraulic steer to help turn the 42 inch tyres i'll be running.

Have a look here and you will see a couple of pics of the tracks and trucks. http://www.tufftruck.com.au

yeah that looks like the 2 stage 32 ps pump.

I take it that it is only the pump you are using? the rest looks totally irrelevent for what you need.

the trucks look excellent, I love all the custom work in it.....got more close up pics of the chasis

Appologies to cut in - R35s don't have HICAS or are you refering to the V35s?

No not really mate only when there on there side.LOL

I'll be doing a full build up thread on a couple of the 4wd forums when the rest of my bits start to turn up. Heres a link to my old build up which should have some chassis pics. http://www.downunder4x4.net/forum/showthread.php?t=2249 This one isn't as seriously modified as what the new one will be though. I've got to try and sell my old rig first though as it's taking up space. :blush:

I read this thread and thought "rock climbing!"! Cool idea, so I'm guessing that this type of adaptation has already been done on Patrols before?
Yes mate it's a common mod on a lot of comp 4wds these days. I don't know how many guys use these power steering pumps as I think a lot of blokes spent a heap of money on have one made to suit. I spoke to an engineer (fellow 4wder too) who has done this mod heaps of times and he said the most reliable and cheapest way was to use one of these pumps. He just couldn't tell me where to find the info on what Nissans had them and what didn't.

I just couldn't believe how quick a response I got here and it has saved me heaps of time trying to work it out myself. :P:P

Cheers Mick.

wouldn't you be better off getting an electric HICAS rack (R33, R34 etc) instead of a hydraulic one (S13, R31, R32, 300ZX etc)?

I've got a HICAS assemby off my R32 you can have for free if you're in VIC. Took it out so the rear would stop twitching.

I'm in NSW but thanks anyway. It has to be hydraulic one aparently. I have no idea how it's actually getting set up, i've just been given a list of things I need to get and thats about all I know. :P

The hyrdraulics will run the suspension and steer to both diffs. This part of the build is way out of my league but hopfully i'll learn about about this as it gets set up.

Cheers Mick.

      7 Speed Auto transmission fluid change (Skyline, Q50, Q60, Fuga, Q70, A62 Titan and probably heaps of others including Navara...)

      By Duncan · Posted

      OK, Step 3, if you need to remove the valve body, either to replace it, the TCM, or to do a more complete drain.  First, you need to disconnect the TCM input wires, they are about half way up the transmission on the drivers side. One plug and the wires are out of the way, but there is also a spring clip that stops the socket from sliding back into the transmission. On my car the spring clip was easy to get, but the socket was really stuck in the o-ring of the transmission housing and took some.....persuasion. You can see both the plug to remove (first) and the spring clip (second) in this pic Incidentally, right next to the plug, you can see where the casting has allowance for a dispstick/filler which Nissan decided not to provide. there is a cap held on with a 6mm head bolt that you can remove to overfill it (AMS recommend a 1.5l overfill). Final step before the big mess, remove the speed sensor that is clipped to the valve body at the rear of the box.  Then removal of the Valve Body. For this the USDM Q50 workshop manual has a critical diagram: There are a billion bolts visible. Almost all of them do not need to be removed, just the 14 shown on the diagram. Even so, I both removed one extra, and didn't check which length bolt came from which location (more on that later....). Again it is worth undoing the 4 corners first, but leaving them a couple of turns in to hold the unit up....gravity is not your friend here and trans oil will be going everywhere. Once the corners are loose but still in remove all the other 10 bolts, then hold the valve body up with 1 hand while removing the final 4. Then, everything just comes free easily, or like in my case you start swearing because that plug is stuck in the casing. Done, the valve body and TCM are out

      OK, so if you are either going for the bigger fluid change or are changing the valve body which includes the Transmission Control Module (TCM), first you should have both a new gasket 31397-1XJ0A and a torque wrench that can work down to 8Nm (very low, probably a 1/4 drive one). You can probably get by without either, but I really didn't want to pull it all apart together due to a leak. First, you now need that big oil pan. The transmission pan is 450 long x 350 wide, and it will probably leak on all sides, so get ready for a mess. There are 24x 6mm headed bolts holding the pan on. I undid the 2 rear corners, then screwed those bolts back in a couple of turns to let the pan go low at that end, then removed all the middle bolts on each side. Then, undo the front corner bolts slowly while holding the pan up, and 80% of the fluid will head out the rear. From there, remove the remaining bolts and the pan is off. You can see it is still dripping oil absolutely everywhere...it dripped all night.... I got another couple of litres when I removed the pan, and then another few when I removed the valve body - all up another 4l on top of the 3 already dropped in step 1.

      Wheel Sizes & Offsets For Skylines

      By Black_CSR · Posted

      Yeh I think i'll message an old contact i had for ages that manages his own tyre shop now.. n tell him what i want n work with him before ordering..  Got this 17x9 +30 Driftteks on 245/45/17 PSR Drag Radials on the rear.. They fit well - for your reference in future - Rear guards  have been lipped in & minimal to non flaring of the rear Gaurds.

      Wheel Sizes & Offsets For Skylines

      By Kinkstaah · Posted

      If only it were that easy! I also needed to remove seats, shocks, brake calipers, send my car through a fence, and use measuring and ended up guessing because I didn't remove seats, shocks and brake calipers. It can be hard sometimes Can be a little more complex than 'just measure' if you want to truly measure the entire wheel through all of it's suspension travel. But if you aren't going for every last mm then yeah, you can check the space you currently have and guesstimate.

      If you own a car, and it has wheels on it, and you know the offset of those wheels, and you have a measuring device, you have everything you need to work out if other wheels will fit.
