RE: Nutech 5SC Build
Still putting the rear together. I like the fact the pinion gear in the diff is also keyed, it is a much better design then just having a flat spot on a round shaft with just a grub screw bearing all the load. Nutech decided to change their lower arm mounts, they went from an alloy mount to a hybrid of plastic and alloy, I think I prefer the all alloy mounts...this is something I am pretty sure I will be upgrading in the future. I do like the the fact you can change the rear toe just by changing the inserts. The inserts on the rear arm mounts have a 2 degree toe, the truck also came with some 3 degree inserts. I also decided to change the stock diff case screws with bolts and nuts, I have found that this really helps keep the diff case from spreading under load and keeps the diff ring and pinion gears aligned.
