I like these instructions.
Put the BOTTOM NUT on to about 50 Ft.Lbs. (a good idea to start the then start tightening up more as you run the knuckle through it's range of motion,
When you start to feel drag, STOP.
If you don't feel a lot of drag, STOP AT 75 Ft.Lbs.
Tighten up the Threaded Split ring to around 50 Ft.Lbs. and leave it alone.
Tighten the top nut down to about 50 Ft.Lbs. and start running the knuckle through range of motion,
Tighten until you start to feel drag, then stop.
DO NOT EXCEED 85 Ft.Lbs. no matter what drag you feel...
With larger vehciels with larger studs, you can go up to about 100 Ft.Lbs. and some Jeep manuals recommend 100 Ft.Lbs for Jeeps,
But I've found that 85 Ft.Lbs. is PLENTY to keep the top stud in place and keep it tight.
