Re: Ratio Change
You have to get the pre-load perfect otherwise the gears will not last.
This is perhaps the most crucial job of all gear-related jobs. It should not be tackled without specialized tooling and LOTS of research.

Re: Ratio Change
I find it interesting that the aussies like to put 35" (or even 37") tyres on their Patrols, but here by us it is not a common practice. Maybe it is because they got more parts (like diff gears, etc) available there by them.
Seems to be a pricey upgrade though: http://www.marks4wd.com/nissan-patrol-diff-gears.html
(Too expensive for a South African's budget..unless you can source the diff gears locally)...

Re: Ratio Change
So your best bet is to find a 3l manual and do a midnight axle swop?
Thatshould almost exactly make up for 35's vs 33's.

Re: Ratio Change
Auzzies do it for lots of reasons:
1: Far more companies who specialise and understand Patrols / Cruisers making it easy and reliable to modify, incl diffs and availability of quality parts.
2: You cannot drive their trails running 33's because they so rutted from 35's... thats why they all starting to run 37"s - natural progression
3: Far greater access to real-world engine mods (particularly Diesel powered motors) , Making it easy to turn that rubber.
4: Highway speed limit is 100km/h. So even if your motor is bog standard, there's no real issue on the road anyway.
The irony is that its illegal in most states there to run 35's or bigger. same goes for anything over a 2" lift. Unless they get it engineered approved.
If i had my way i would love to change my gearing to 4.3 / 4.6 on the pickup and then run a 63% transfer case reduction gear for low range application. using 35's.

Re: Ratio Change
So many things would be possible if budget wasn't an issue.
My dream car involves portal axles (to sort out the ratios for 35's) on a 4.8 shorty with x-link front end and a carbon-fibre body and a 3-speed transfer case: 1:1, 2:1 and 4:1...
Because 2:1 is just about perfect for dunes.

Re: Ratio Change
hahaha.
Yeah, portals would be my choice above all else. Portals means Zero steering / suspension issues, basically would drive like a stocker, accept for the roll of the 35 /37" side walls!
