Inspecting control arm balljoints

[Scott 88-1JZ]

Hi all,
I am currently installing poly bushings through out my control arms rear first then the front. I have a question regarding inspecting the ball joints (upper control arm). What is the proper procedure for checking the turning torque. I followed this from the TSRM.

note: my 92 manual I own states 9-30 ft-lbs. that is quite a typo:nono:

Can someone clarify when the ball joint is bad? I am taking this spec to read that the ball joint should not take more than 30 in-lbs of torque to turn. Also the boot oozes out some grease out of the top as you move the stud back and forth. I think that when the joint is torqued down it would seal against the face of the arm. is that right?

Bump, I would like to figure this out so I know if I need to drop $$$ before reassembling my suspension. Someone on here has to know.

Thread the nut onto the control arm until it bottoms out(only finger-tighten it)
With the arm upside down, stud facing up as shown in pic, using a gauge type torque wrench <HERE>

Measure the amount of torque it takes to turn the nut, which, in turn, will turn the ball joint inside the socket. If it spins less than 9 in/lbs of resistance, it must be replaced.

Thanks for the reply. In my ongoing search I also came accross this page. Which is a tech update I believe. It differs from the service manual where it says 31 in-lbs or less.

I have tessted most of the arms and there is no vertical free play felt and the torque seems to be in the range of 10-15 in-lbs. I am hoping this is good and now just kinda of seeking conformation to my above assumption that less than 31 in-lbs of torque to actually turn the ball joint means its good.
