We are a bit disapionted with the fuel consumption of the 03 Nullarbor auto. It has the push button on the dash to engage high range 4wd. Has any one put free wheeling hubs on one of these and did it make any diff.

Pete

Boldjack (my BIL), did his hubs and got a good improvment, also there is the whole issue of no wear on components as well.

Good luck with it.

cheers

Pete, I've owned a 98 (3.5 petrol auto) and an 01 (3.5 petrol auto wide track with shift on the fly). Can't say I noticed much difference in consumption between them (both about 17 lit/100 around town). Nevertheless it did annoy me that the front hubs, shafts and diff were spinning full time. I've downgraded to a GQ. Of course the consumption is worse but it's on LPG. Rob.

Rob that arround town fig hurts.My manual was doing 15s arround town before the special tune up. Sal has kept very detailed consumption records. When we first got the 03 it was doing 22(ouch) after pumping up the tyres, all new filters and changing her driving habits its now down to 18.4. Should have kept looking for a manual but this one was in such good nick it was hard to pass up.
Thank you Pete

Wow Pete I thought the prado was bad (well its not great LOL) 18.4 sounds pretty high to me even for a mid size 4b. The prado is averaging 17.2 around town on petrol and up around the mid 12's to 13's freeway. I have to take back to the gas bloke next week, since he tuned it it's not real good on the LPG. Filled up and checked it today, 24L per 100 on LPG Ouch city/freeway, hardly worth running LPG with those numbers. When I first had it put on it was running around the 21L per 100. Getting rid of it so not really concerned but want it tuned write, seems to be running fine. When he checked it last time he said it was running a bit lean....... WHG

When I brought Mine Whg heaps of people told me how thirsty they where, I then found it quite good so did not take much notice of the pundits and got caught out 2nd time arround. Still she loves it, and it feels more Refined then mine. Sal has just got home after taking mine and reckons she feels like a hoon lol.
Are you getting another Prado? Should be able to pick up a 120 4l for low twenties now.Good luck
Cheers Pete

Hi Pete, not sure yet. Im thinking either another 95 seres prado but turbo diesel (1kz) or base model second hand hilux with D4D but has to be auto for the other half, not many around and at the moment holding their value like all hux's. Have seen a couple but up around the 30g mark. Missed out on a TX T/D prado this week but have to sell mine first. Dont want to be cought out with two of them. Was thinking of getting t/d prado first and swapping over the suspension, bullbar,cargo barrier,tyres etc then sell the petrol one but bit worried I might not sell it quick enough so dont want to take the chance. Spewing I didnt keep the original springs struts etc. Miss the room of the hilux with the canopy and with a little one now we take even more crap thought it was bad enough with the other half LOL.......WHG

Hi Pete.
Yep, done the manual hub conversion,quite easy to do.
Hoped to save a bit of fuel, don't know how much, but it seems to be a bit nippier around town.
The other benefits you gain are less wear and tear on the front drive,as with the hubs you have now as it's always turning over even when not in 4wd.
If you damage a cv on the track in the middle of nowhere you can simply disengage the front hubs a get home.
Also it gives you the option 2wd low ,handy for reversing trailers ,especially on steep driveways etc.
Just be careful not to select 4wd (sotf) while still moving with the hubs disengaged ,could be very damaging .
Hope this helps
Cheers BoldJack
P.S. This my third attempt to submit this post in as many days. Don't know what I'm doing wrong but it just doesn't get through.

Hi Boldjack,
Thanks for your reply. Did you source your free wheeling hubs from a wrecker or buy new ones. Is the Jack system similar to the hilux add system where the diff disengages.
Cheers Pete

Hi Boldjack again,
mate in a post above this one I commented on the acm tune up. I just achieved 13/100 towing my 4.2 boat, but sitting on 90( I know bloody hard to do). This is an improvement of 1.5l/100.
Sorry this is in my 98 manual.
Cheers Pete

Hi Pete

I just bought a used pair from the wreckers for $90 ,they were in really good condition.
I think you need to get them from a pre 1988 model Jack ,But please don't quote me on that ,I cant find the U.S trooper site I got the info from.
Hope this Helps
Cheers BoldJack
