Thread: D2 Part Time 4wd - LT230

im not shaw but it looks like a bloody good idea. i wouldnt mind doing that to my rrc except i think they were made 4wd to spread the power load and save diffs?

Ashcroft Transmissions - LT230 Part Time kit

The only advantage I see, if any, is possible less wear and fuel consumption for extended touring, highway and city driving.

From what I can tell you may need to swap out the front for DI or Defender axles etc. to use the freewheeling hubs.

Would there be any benefit in this mod?

Take your front shaft off and go for a fang, trust me, you'll soon change your mind about part time 4WD in a D2, they are bloody terrible to drive rear wheel drive only

You'd never recoup the costs in the saving of fuel (if any) and wear and tear. In fact, there is a body of opinion that says you will cause more wear with brinnelling of the bearings.

To top it off, you'd lose the advantages of AWD.

A mob in Adelaide were selling kits for the D1.

I'll agree there had mine with the front shaft out to put new uni joints in. In the rain on a round about its really easy to have rear end trying to over take you. Not very fun for the long term

That was the idea originally.

The V8 and Tdi's and particularly the TD5 would toast the rear diff reasonably quickly with all their torque going through it.


As Ron said, I've had part time 4WD's and know of others that brinnelled the front pinion bearing and stuffed the driveshaft splines from sitting in the one spot on rough roads.

On the Patrols we regularly run them with the hubs in just to lubricate the diff and make sure the front driveshaft doesn't stay in the same spot for too long.

Standard MO on part-time 4WD up this way... but thats mostly laziness in not wanting to get out and lock hubs!

I wouldnt want to reduce the on road handling and safety of vehicle, increase strain on the rear diff and create an inconvenience for off road driving for a tiny gain in fuel economy?

Most manufacturers have now learnt how good the road manners of Rangies and Discos are and are now producing the same drive trains. The only reason 4wd vehicles with lock in hubs are still produced is because the centre diff transfer case is costly. For what its worth although a little off topic, I had 2x Mitsubishi Galant. 1x 2wd and 1x AWD (same as a Disco without CDL) Fuel consumption was within 0.1 litres/100km.

cheers

Only benefit would be doughnuts on the beach but i dont think most of the D2 owners in here subscribe to that way of thinking :P

The rear dif would probably cop it if it was an ARB wrapped in some ashcroft gears and axles but otherwise youd be buying new housing every few weeks, especially with a V8.
