Locking differential!!!!!!!!!! By all means, someone correct me if I'm wrong. A 4wd truck with LSD that gets in a bind will only have two wheels spinning at all times (one front, one rear). At least with a locker, you could have three wheels pulling 100% of the time. I think a locking diff makes a world of difference. In 2003, I bought a DC 4wd Tacoma with locking diff., my buddy had a 2002 Ford FTX 4wd with LSD. After consuming an absurd amount of beer, he kept talking smack that he could pull me around with his truck. We chained up hitch to hitch. As God as my witness, my locked 4wd Tacoma pulled his full size truck about four feet until he applied his brakes. And just before I bought my Tacoma, I test drove a Tacoma 2wd prerunner with a locking diff and I thought that was a pretty good set-up. Anyway, now I have a 05 DC Tundra 4wd with a LSD. Until it's paid for, I will never put my Tundra in a bad 4wd situation. But I guess it would be nice to know you had a locking differential.
