Been saving up for a while, birthday money, etc. Hope Santa finishes the job and I can get a locking differential for the sport trac. I had a Powertrax in the '93 ranger for years and I loved it. Had to replace the springs in it after about two years when it was acting up a bit. When I got the sport trac, I got the open differential specifically so I could put in a locking unit. So far I've had the truck for 6 years and haven't done so yet. Finally the day may be close! I am considering the aussie locker or another Powertrax noslip. I remember reading a post on one of the 4x4 boards by someone at Aussie that talked about how the Aussie is designed better than the Powertrax, but can't find it anywhere. I think it was on pirate or a jeep forum. Anybody know the thread? I used to have it bookmarked on the old computer. Grrrr.
