Outer Limits 4x4 Board

just wondering if anyone has installed a part time 4wd kit onto a series 1 disco, and what do you think? any better fuel economy? nicer to drive around town etc?

i put one in my defender alot of people will tell u not to bother but i think it is one of the best mods i have done .kills the back lash lighter steering less noise and vibration

Where did you get the part-time kit from? Does it come with FWHs as well? What model transfer case does it fit?

Thanks

4wd systems $500 with hubs the first hubs were avm but they didnt fit so they replaced them with fairy type i think avm make the kit look at there web site so any one who stocks avm can get the kit it fits all lt230 tranies

Thanks

Peter K

I couldnt find anything on the AVM webiste other than just the manual locking hubs but found this on the 4wd systems website
http://www.4wdsystems.com.au/html/part_time_4wd.htm

for those that have this kit fitted, was it as easy as they claim it to be ie five hours and no specialist tools required. Also, how is the kit performing, any drama's.

This disco of mine is the first constant 4wd I have had and would be interested in changing it to part time 4wd

cant really have any probs with it the rover kit is just a bearing and a puk .i got my mechanic to fit mine the trannie needed new seals anyway. cost $300 to fit

why???

If you don't know what a puk is you should NOT be attempting this modification!

Just kidding, I don't know what a puk is either.

thank for that defmec. at that price y wouldnt u!

Because it sucks, can't drive nowhere near as fast with rear wheel only

Land rover only built the Range Rover as a constant 4WD because the stock Land rover diff wasn't strong enough to cope with the torque of the V8.

A defender with the Sailsbury rear should be fine, but I don't think I'd trust an S1 disco rear diff alone to push along a discovery without some significant strengthening.

Makes me laugh whenever I hear that

whats even funnier is the diffs are weak enough to break with the torque of the v8 even with constant 4wd

as i stick to the speed limit on road and don't drive like a dik hed and off road can still have hi 4x4

puk sorry (gear) but it looks like a puk

So haveing better brakeing, handleing, etc isn't of concern

puk isn't a word. You mean puck - as in a hockey puck.

I can't see how changing to 2wd would reduce noise and vibration, unless your front diff/prop/t-case output is buggered.

I went the other way. Pulled the free wheeling hubs off my IIA and fitted solid drive flanges. Didn't make the slightest difference to fuel consumption.

Constant 4x4 is MUCH better - especially on wet roads.

I too dont understand the reasoning behind it.
I was unfortunate to have to drive home from LCMP after destroying a front diff.

The car felt like crap in the corners, there was absolutely nothing beneficial that I can think of.

Slightly off topic - I also had to drive home from the springs once with front wheel drive only (broke both my rear axles), that was a disaster waiting to happen... If anyone has a range rover and ever has to drive home under fwd please do not attempt to use any form of spirited acceleration. Limp home and don't boot it when you have the shits stuck behind a combie doin 80 on the highway!

stick with the constant 4x4 you will regret it.

2wd in a constant 4wd is just crazy not to mention unsafe ive run my range home on rear only because of broken front diff pulled the axles and dropped the front shaft it was all over the shop driving home wouldnt recommend it at all

i have the part time kit fitted but have gq diffs and mine handles just as good and my front unis last longer

Heh I've been there twice :) Tho I have to say the only real difference I noticed was accelerating at low speed would torque steer and lil wheel spin :)

I went from the right hand (on coming traffic) lane to almost off the left hand side of the road in about 4 tenths of a second
Wheels screeching madly as I attempted to correct the torque steer

Lucky I was not beside the combie else I would have smashed straight into it. Instead I just missed the back of it and then after regaining my testicles decided that being pissed off with the POS was not worth it!

At low speed it was not much more then a slight pull, but over 80ks and booting it was a different story. NEVER AGAIN!

Having complerted 2 Selective Stage sin the Australian Safari with no front drive shaft I have to say it didn't change the handling appreciably.

It did let me get stuck on a creek crossing!

I drove it quite afew K's on the blacktop to the overnight stop before repairing it and again it dind't cause me any concern.

May be I'm just too stupid/crap driver to notice.

Have to say it happen to me once, rear diff went bye bye... Having a FWD V8 was a bit of fun, for a few minutes, before I realised I still have that Viscous Coupling unit...

Not that I should be bragging, but lighting up the front wheels in a Range Rover made me laugh

I am looking at the 2wd kit for my D1, after putting one in my 80 Ser in 2002 and found it to be the best mod I’ve done. All pros and no cons, the back lash was the biggest issue and it fixed it just fine. Felt funny the first few days but after that I could not tell the difference. Makes me laugh ever time some one tell me something but has no experience just there opinion. As a former panel beater I fixed a lot of damaged cars and when test driven they drive just fine, yet the when the owner got it back they said it drove different then before the smash but two weeks later it was just fine.

So if you have never done it don’t try and talk someone out of something just because you would not do it.

While that may be true - the first 3-4 years of series 1 production were also constant 4x4.

When the 110 was introduced, part time 4x4 was available as an option, but was dropped shortly after as it was unpopular.

I can tell you from experience, that a rover 10 spline diff is strong enough to light up 29" tyres with over a ton on each axle on dry tarmac.
I call bullshit that they weren't strong enough. Offroad when locked up either diff is called upon to take far more load than a single diff onroad can take.

You can break anything if you drive like an idiot.
