Well, the maintenance issue makes sense. I've put only about 40 miles on the 'runner since I picked up my Supra in April so it has been basically sitting since (it was my dd before that).
This '88 was a replacement for my '87 (stolen 8/07) that I meticulously maintained. I've been finding out the longer I own it that it hasn't been maintained as well as was stated to me by the previous owner. This afternoon, I went to plow my lot in 2WD with some added weight in the back. I kept it in 4H the entire time even though I was only getting the right rear driving. I shut the truck off to move my Supra and when I got back in to pull it in the shop, the 4WD was working. So, for now, I'm going to leave it in 4WD since I'll need it for the snow storms coming this week. I'm still going to look at converting to manual hubs.
