Hello all just acquired a 1991 trooper, 5sp w the 4 cyl, found and fixed a no start issue, replacing floor mats, inside door handles, minor stuff,
need some help on 4wd system, transfer case goes into high and low range, but no 4wd, has auto hubs, question is,, is the system actuated by vacumn, electric or strictly mechanical?, ie:transfer case equals 4wd when in 4wd?
tnx for help
