Problem: When low ratio is selected front diff will not engage but
works in high four wheel drive.

Question: Is low for front diff engaged purely by selection lever, or
is it engaged electrically over vacuum?

thanks
Tony

If it's anything like the 4Runner/Hi-Lux Surf, it's by vacuum. Are the hubs
in Lock position?

I remember reading on an off-road website on how to check the vacuum hoses
on a 4Runner. I remember the early 90's 4Runner and LC shared the same
engine and drive train, with the possible exception of Diesel engines. If
you do a search for "88 Toyota Land Cruiser", you might find the link or a
shop manual.

I have a copy of a shop manual in pdf, but I need to look for it on one of
my PCs.
