transfer box engages but does not engaged front wheels properly

well i found this out as i had it on the dyno machine in 4w/hi and 4w/low, even at 50mph on the roller the front wheels where mearly rotating at 10mph, what could i be looking at? i can hear the transfer box clonk into 4w/low, could it be internals?

hello mate,not totally sure but i dont think you should do 50 mph in 4x4 low it could be a saftey thing cut in ?

well it would be the same situation if you wanted to get out of stuck in snow, i dont think i want saftey feature lol, even in 4w/hi it was mearly rotating.

cheers feller, im going to test the power supply on the plug behinde the shifter motor, as i read on the usa bit, it should be 12v continuas when locked in 4/hi

Just a thought.... does the Explorer split 50/50 when the transfer box is used?
I know some cars do 60/40 70/30 etc with more power going to the rear wheels.

i think in low its 60/40 but 4w/hi should be 50/50

This link should answer some of these questions. The Control Trac system is present in all of the UK sold RHD Explorers (96-2001). In 4x4 Auto the split is 10/90, in 4x4 High & Low the split is 50/50.
