[80] mpg and Assin hubs

[Guest]

Ok Matt,
Some stats on my 1996 US FZJ80-1FE with 116K on it. Auto and petrol and
owned since new.
Have mileage stats going all the way back and need to correlate and average
and all that stuff - and not done so.
However running Aisin hubs on front and dropped front driveshaft (hence 2wd)
with CDL switch before a long trip to San Diego at New Years.
One wife and three kids (ages 10,6,4). Some luggage (up to windows in rear),
Large tool boxs (normally in there)
Driving with 265/16 BFG's getting worn, have alignment issue on front (front
tires wear on inside) and DS front constantly needs its bearing retightened
(needs overhaul)). Pressure at 32-35 (for 4 psi increase). Speedometer
correct via GPS check.
No winch nor extra armour. Sliders with 1.5" lift. No roof rails.
Extra (empty) propane tanks (100L) where spare tire was underneath and spare
tire on swing out rear carrier.
1119 miles to get there
1269 coming back (Gill did some shopping)
total of 2388
Tried to maintain 85+mph on trip on the highway sections (but slower going
up long hills
Pushed the ton a few times but only down-hill and sure there was a wind
behind me and only for testing purposes and very short. Handling felt fine
but a little noiser/shakier.
Min=12.4/max=15.8/average=17.06
Havn't loaded up elevation profile from trip and may do that later (as going
from Denver 5500ft up over 11,000ft and down to sea level in San Diego)
2 trips since that did 12.5, 12.9 and then <1/2 tank(140 miles) for 15.5 mpg
All local stuff maybe 1 trip to Denver on each tank (80 mile round-trip)
Put back on front driveshaft (locked hubs) and local driving around town and
got 12.8mpg so looks as if it doesn't make much difference on the local
stuff (all flat)
So methinks I need a tune-up to see why getting such crap mpg on local stuff

Dear Brendan,
I'm a little out of touch with big petrol vehicles. Because I'm skint I can only afford to run diesels. Apart from my V8 Land Rover 80" but that only does about 1000 miles a year, and they are mostly off road.
However, I think your average of 17mpg is pretty good for a big petrol. If I'm careful I can get 26mpg from my HDJ80 4.2 turbo diesel. But when towing and/or driving fast it is down to much less than 20! My good old rocket ship Discovery (200 tdi with BIG intercooler) was faster and more economical, but not as comfy or quiet!
Anyway, I'm hoping a thundering big intercooler will get my mpg up.
All the best,
Matt in Derbyshire UK

Brendan,
I think the reason that you are wearing your tyres as such is that front
wheel drive and all wheel drive are arranged with toe out geometry where as
rear wheel drive vehicles tend to have a toe in arrangement. You may need
to adjust things. Do you find there is more drive line slop and shunt etc
than before? The reason why I ask is that when I did the UJ joint on my
Landover I ran in 2 wheel drive for a short time with the diff locked and it
was most defiantly sloppy that is drive line shunt. My major concern was
for the Transfer box and the rear output struggling with twice the power
that it was designed for. I should imagine that a transfer box may come a
little bit more expensive that a set of birfields.
