Anyone reccomend a winch for a 2007 Liberty?
In Australia, i think they sell the T-Max winches. I don't know much about them though. WARN is the number one rated off-road winch brand for reliability in North America. I like my winch, the Titan, though. It is a good bang for the buck winch, using higher quality parts than other cheap winches. And so far, as far as i know, only 1 Titan motor has failed in all of North America. Some will say WARN is the only way to go. Maybe true if you are doing extreme off-roading but I like the fact that Titan is a small Canadian company and sometimes you gotta support the little guy. But for you if you can not get a WARN in Australia you could look at the T-Max. Also, the WARN M8000 is guaranteed to fit in the ARB and you need to compare the specs on it to any other winch you want to fit in there.
How much Pulling Power would you reccomend? 8000lb-9000lb?
Really, If you are getting an ARB then the only choices in a winch are the smaller winches that have the solenoids that are removable or mounted not on the winch itself. These include the ones mentioned above and the WARN M8000, XD9000, 9.5XP. My winch is 12000 ibs and has a safety overload switch that automatically shuts off power at 12300 ibs to not overload the winch. The bigger the better but the M8000 will work but i wouldn't go any smaller than that.
What is the OE battery's Cold Crank Amps?
Not sure but I have a yellow top optima battery that is better for winches and other power accessories.
Do I need a bigger/dual battery setup?
No. I think usually 650 CCA is the minimum you need for the M8000. A yellow top would be good. A dual battery would be nice to have but not needed.
What is your typical setup consist of? (pictures would be nice Wink )
The ARB comes complete with winch mounting instructions.
What does low and high mount mean?
Mounting it low versus mounting it high???

Probably doesn't mean much since you're mounting it in an ARB.
