I walked into my local ARB and asked for a price on a front air locker and he asked if I had the rear locked already I told him no he then started to tell me that I should do the rear first I argued that the patrol has a really good LSD on the rear and I would see more benefit if I locked the front first .......... Long story short he didn't agree so I Walked out of there knowing not to ask those Idiots for advice again
