Anyone put an Eaton E-locker on their 2WD 1st Gen Tundra? My 2004 2WD Tundra has the factory LSD, but it has let me down one too many times. My truck sucks in the snow, even with 400 lbs of weight over the read axle. I thought of selling the truck and getting a 2006 4WD Tundra, but if I can achieve the traction I need in the occasional snow and mud (doesn't happen too often, but at least a couple times per year), then I'd be willing to spend the money to get an e-locker. The manufacturer says I need new carrier bearings. Not sure why this is. Hopefully there aren't any other major modifications required. Anyone done this? Did it improve traction dramatically over the 2WD with LSD?
