Would like some clarification on this...
I have a 1992 LJ70 SWB, 2LT engine, with manual front locking hubs.
Been bombing around the countryside and having a great time driving through shallow mud and up steep hills... I haven't had any problems until recently... went up the mountain past the snow belt line and got stuck. Rear wheels were spinning, front wheels not rotating.
Usually, I would press the '4H' button, the indicator on the dashboard would light up, and I would feel a noticeable difference when going through slippery or steep areas. I thought all was good. The guys I go wheeling with said they saw the front wheels 'spinning/pulling' the truck when in deep mud or on loose gravel.
However recently, up in the snow, the truck got stuck. '4H' was engaged, dashboard light was engaged, rear wheels spinning, but not the front.
I get out and manually turn the front hub (both sides) from "Free" to "Lock"... now the front wheels spin. Got out of the hole, and was on my way again.
Yesterday, got stuck in some deep mud. '4H' was engaged, front hubs were in the "Free" position. Rear wheels spinning, front wheels doing nothing. After putting it in the "Lock" position, the truck ploughed through everything.
Here's my train of thought...
- Pressing the '4H' engages the front drive shaft and makes the front wheel spin...
- Turning the front hubs from "Free" to "Lock" causes the fronts hubs to lock and spin at the same rate and so help create more traction
- 4H is to be engaged when at a standstill and gearbox in neutral (my truck has a 5sp manual gearbox).
- After moving hubs from "Lock" to "Free", the hubs and 4H would not disengage until I reverse a little, otherwise the '4H' light on the dashboard blinks (noticed from experience)
I can't look up the operation of the system in the owner's manual as it's in German (my truck was imported from Germany). Tried searching, but a lot of info out there is regarding the electronic locking hubs.
Can anyone please shed some light on the operation of the drive system that is equipped with manual front locking hubs?
Thanks,
Carib.
