The truck:
NAME: Random (daughter of Arthur Dent)
1987 BJ74LX 173,000km originally imported by Luxury Imports, Sold to me by Snowking

The parts donor:
NAME: Ol Smokey
1986 BJ74VX 250,000km Formerly Crushers’ trail rig

The Plan:
To create an expedition rig equally at home on the Alaska Highway or the Rubicon. The goal is to find the fine line between off road ability and on road drivability, even if I have to spend the price of a tow rig to do it. I have accumulated most of the parts to assemble the rig but have no shop to do it in anymore. Most of the fabrication will have to be outsourced.

Front axle;
60 series axle, sprung over, shackle reversed, out boarded springs. 4x4 labs steering arms, DOM rods, hydraulic assist, 4Runner calipers. 80 series locking diff modified to air actuation. Custom axles and Longfields.

Rear axle;
60 series FF, 4 link on airbags, factory cable locker modified to air actuation. Custom axles.

Drivetrain;
Stock for this year, dialed up boost and fuel. Marlin Toybox to follow.

Accessories;
Technitop roof top tent, 24V Waeco Fridge/freezer, Webasto diesel heater, CB, Ham, 24V Cat radio. Drawer system, RMM onboard shower&shower tent.

Bumpers;
Custom home built. Front has mounting for winch and IPF lights. Rear will have facilities for mounting spare, fuel cans, high lift.

Winch;
Hydraulic Superwinch. Powered by PTO hydraulic pump 11.2 gal/min, 200ft Amsteel blue

Tires;
Off-road. 11.2x16 (37.5”) Titan Tractor tires on custom 16x10 3”BS Steel rims.
On Road (undecided) probably 38/14.5-16 Toyo Open Country MT on 16x10 4”BS (aluminum) rims

Trailer;
1990 M101cdn s/o 35” tires for hauling tractor tires to trailhead when required.
Bruce, I'm not excited. Let me help you out a bit.

Truck is a BJ74. Damn good truck to start with but a expedition vehicle? Ok, well, lets go from there BJ74 expedition vehicle for the Rubicon or Alaska..

Take your BJ74 and do a good solid SOA on it. I agree with a good steering system. 4x4Labs will handle it all that you mentioned. Re-enforce your frame where the power steering box is!!!

Hit up your front axle with a bit of chromoly axles and birfs (30 spline) in the front( 27 spline chromoly birfs will work fine too). In the rear get a good set of drive plate studs for the rear.. Need a rear traction bar for sure. Everything else will be ok.

13B-T with with 40" radials will be fine. 13B-T with bias plys no bigger than 38". 4.88 gear change. You will be fine with no trailer required. Will not be a speed machine but it will keep up.

Put breather tubes everywhere. Hit all points.

If need be go to Downey and order your cables for you lockers. IMO do not put a non-mechanical system into the picture. Downey will custom make the cables for you if you ask them.

IMO your plans are way too jiggy. You can get that 74 to work like a charm and still be drivable at NA highway speeds. Spend the rest of your monies on making it a happy vehicle for your comfort.


Just My Opinion.

Regards,

Randy
