Late to this thread, but will add:

I have a similar situation with my 2002 SR5 4wd. At 165k miles, I haven't been able to find out (via VIN search) if they LBJ's have been replaced when the recall was still active back then. They don't have much play. But yikes, those images of LBJ failures got me freaked out.

So I pulled the trigger and ordered all the parts to bring to my local shop. I went to Toyota Parts Factory - #1 Source for Genuine OEM Toyota Scion Parts & Accessories | Camelback Toyota Parts in Phoenix to get OEM parts.
Total for L and R ball joint which includes new nut and cotter pin, plus 8 new bolts came to: $295.85 which included state tax and shipping to Los Angeles.

Toyota PN Desc:
90119-10933 Bolt W Washer
43330-39585 Suspension Ball Joint (Right, Front, Lower)
43340-39465 Suspension Ball Joint (Left, Front, Lower)

These are for an '02 not sure if the part numbers are correct for similar years.
