I am having trouble with my 90 v6 3.0L sr5 5spd. I found out the other night in some wet muddy grass that my front wheels do jack when in 4H or 4L. I almost got stuck at the bottom of a little grass hill! So obviously something is wrong. I am going to try switching the vacuum hoses but will I have to do that every time I want to go 4 wheeling?? Im not to sure I understand. If switching the vacuum hoses does get it working, do I switch them back when Im done and it should work fine afterwards without having to switch them again?? Also does my 90 fully loaded even have a 4WD light? Because if it does then it has never come on. I only got the truck last week and it seemed to work fine in 4H and 4L in the parking lot but it took some slippy grass to show me the front tires arent doing anything at all.
Please let me know
Thanks
Jeff
