i just purchased a 1999 Tacoma SR5 this weekend. the seller was very touchy about testing out the 4wd. he says you should never, ever use 4wd on a dry road. he took me on a patch of grass and demonstarted Hi 4wd for about 10 seconds. it seemed to work great. he put it in Low 4wd and drove about 5 feet. --so at least i know it works.
but is this true? --is it really bad to use 4wd on a dry road? is he exaggerating?
