I just got done with installing my 6" tuff country lift and 14 bolt rear end. I measured driveline angles and came up with this. Transfer case = angles down at 6.5 degrees 14 bolt pinion = angles up at 7 degrees Slope of driveshaft = 23 degrees Doing the math it looks like my u-joints will be operating at 16 and 17 degrees respectively. Will a stock 10 bolt u joint and napa 447 crossover U joint run at these angles? The pinion/transfer case seem to be fine, but I am worried about how long the u-joints would last at these angles. /forums/images/graemlins/1zhelp.gifThanks.
