I have Aussie lockers front and rear and love them! I bought them at their introductory price for less than $200 each. Once you get used to them the on road manners are not a problem, what happens is, as you shift gears the cross shaft in the diff goes slack, and as power is applied in the next gear one rear wheel is driven before the other. this causes a slight pull to one side or the other until both wheels are being driven. It doesn't take long to get used to it, The clicking has never bothered me at all, it is barely noticable unless you're coasting around a corner with the clutch disengaged, then it can get fairly loud, it just means the locker is working like it's supposed to. I like seeing the looks on peoples faces sometimes as I pull into a parking lot and they try to figure out what on earth is wrong with my wheels! Don't believe the 2 hour install time claim though, the Carrier has to come out of the 44 for install and it was a B***h getting mine out, with out a case spreader the carrier has to come back perfectly straight or it will bind big time. I had to remove my Fuel tank to get enough room to work on it, a couple hour job in itself! Well worth the effort, time and money though! <img src="/forums/images/graemlins/lol.gif" alt="" />
