The DT bracket can be tricky
When I did mine this Fall, it took me a few minutes to convince myself I had the bracket set-up correctly and in the right place. Once I was sure it was properly located the rest went easy. I'd say about 1. 5 to 2 hours for the job with a good 20 or 30 minutes of it studying the bracket. I wanted to be sure before I hole-sawed two holes in a frame cross member. What surprised me was the ease of centering the axle. I did the levelling springs at the same time and the axle was off to one side pretty good. I was dreading centering the assembly. No problem. Had it within a 1/16" side to side in about 3 minutes. You will enjoy accurate steering, especially if your truck is like mine and its been getting gradually worse over time.
