after finishing the assembly on my front hubs, i noticed that i was supposed to torque the lock nuts down to 150ftlbs.... but when i took them off they were completely loose, like, less than finger tight, freespinning loose..... im wondering if that was contributing to my "porpoising/bouncing" problem i was having going down the parkway????

Only the outer locknut gets torqued to 150 ft. lbs.

I have a 1976 K5 Blazer (Dana 44 front with larger inner bearing spindles) and the 150ft-lbs of torgue is way too much. I read that spec once in a 4WD Magazine and riuned 2 sets of spindles before I got smart and ordered GM Service manual. The specs for this axle/this spindle are inner nut-50 Ft.lbs, back off nut and retighten to 35 ft lbs then back 0ff 1/4 turn. Outer nut 65 ft lbs. I have used these spec requirements for 2 years and have yet to have any problems.

no no, i didnt do the inner nut that tight, i did the 50, back off, 35 back off as i was supposed to, then tightened it till i didnt have any play in the rotor, then tightend just a touch more to be safe. and i think i probly only got the outter nut down to 110 or 120 or so, the tool started cocking sideways like it was gonnna pop off so i didnt push it any more. i was just thinking that the bouncing down the road, or as it was described, "humping the road", may have been cuz my rotors were loose.
