Ok so I've had my rear locker in for a couple of days now and I have experienced the the drivability issues, but to me it isn't that bad. I just have to be careful with the throttle around corners. I also got to do some mud bogging yesterday with my brother in law who has a lifted Toyota, same size tires as me but with open diffs. I noticed when he was driving forward in the mud all four tires were spinning but when he lost forward momentum and tried to back out, only one front and one back were spinning and he was stuck. When I was in the same situation, I could still easily back out. This got me thinking, when I'm backing up, the locker is actually in the front now. I was on to something lol. On muddy hill climbs, the rear locker pushes you to the top, but a front locker will help pull you over the crest when the weight is shifted forward. So with that being said, I'll be getting a selectable locker for the front. In my opinion fully locked is the only way to go.
