Okay, I been working on my front end this week trying to get it ready to upgrade my 70 blazer to 3/4 ton running gear. Everything was going fine, removed the brakes, spindles, axle shafts, etc. Went down to Autozone and rented the ball joint removal tool and was planning on installing all new moog ball joints today. Wrong! I spent all day just trying to get the knuckles off! Upper castle nut and threaded collar came right off...removed the lower nut and lower snap ring. I cannot get the the lower end of the knuckle to separate from the axle. I tried a BFH with a picklefork, soaking in PB.....it won't budge. The only thing I haven't tried is the torch. Am I missing something here or should it be this hard?
