Ball Joint Adjusting Sleeve

Hello, all. I just replaced the ball joints on my '73 Chevrolet K20 with a Dana 44 front end. I did everything in the right order:

1) Tighten lower ball joint to 70 ft/lbs

2) Tighten upper ball joint adjusting sleeve to 50 ft/lbs (per GM specs)

3) Tighten upper ball joint castle nut to 100 ft/lbs.

When I tightened the adjusting sleeve on the upper ball joint stud to 50 ft/lbs, about 2 threads are visible under the axle "big C". Will this be an issue? Moog actually asks for the sleeve to be tightened to 70 ft/lbs, but I think that would have been overkill. When I removed the old adjusting sleeve, it sat flush in the big C.

I did everything per the Haynes, Chilton, and OEM assembly manual. The manuals call to check preload with a fish weighing scale, and it is supposed to be no more than 25 lbs of force when turning the spindles. It does feel more than that, but I'm assuming I have to allow for break-in.

I will post a how-to article with a lot of pictures in the near future. Thanks for all the advice.
