Warn Premium lockouts on the front. Worked Awesome. Got 1200.00 in break work done from Big O tire, yeah first mistake. But now Driverside hub gets tighter and tighter when going from free to lock. tight enough that I can't get it to the lock side. What gives! opened it up packed full of greese , that sucked, Anywho it turns pretty free when its not attached but when I put it back on tighter. AHHHHHHHHHHHHHHHH!!!!
