I have a 2007 single rear wheel 6. 7 six speed manual truck, it went about 60,000 miles before the first driveshaft went out and was unrebuildable, bought a another new one from dealer about 15,000 miles ago, its out now, this truck has no lift or any tuner or high performance equiptment, its all stock. Is there an aftermarket solution to the cv front driveshaft that dont last in these trucks from anybody aftermarket?? The mechanic says the yoke that the driveshaft mounts is wallowed out as well. I was wondering if there was a way to get a driveshaft made that was greaseable and a new front yoke that would be matching, I was told these 2007 have new front diffs and nothing aftermarket is available yet??? I still have my old one and am going to call some places in San Antonio like Planet Pickup, San Antonio Brake and Clutch and maybe one of those driveshaft guys that always advertise in those 4x4 Magazines, i think Tom Woods drivelines or something similar, right now i have pulled the noisy 3 month old shaft off and am running in 2 wheel drive, I sure wish I had been able to buy those locking hubs from Dyna whatever, its crazy to have a fulltime diff in this day and age for sure. it has been pretty muddy down here last 3 months but geees, stock truck, no lift and stock size all terrain tires should not be wiping out the front diff like this, $450 a pop plus install is way to highhhhhhh!!!lol
