Hello, im tractor stig on the difflock site, its down at the min and recognize your name, does your front prop shaft lock up solid and turn when you activate 4wd of any sort? if not that will most likely be sticky solonoids on the transfer box or the vacuum diaphragm inside it not moving the slider, personally you cant beat the full manual transfer boxes, electrics/pipework + outside and water dont mix, as for auto hubs Suzuki are Suzuki and daihatsu are daihatsu/toyota so no nothing will fit, the hubs can be purchased from various sites. If your auto hubs are not working you need to check your front prop first, as there is an order of machinery parts 1.engine 2.gearbox 3. transfer gearbox 4. prop shafts 5. diffs 6.drive/halfshafts 7. hubs.....if your prop doesn't spin then you wont know if your hubs are working unless you turn it by hand with the front jacked up.
