I also decided to upgrade the sway bar while I was at it. There's a huge difference in the tightness of the steering. Glad I did it.
    I got lucky with the PB Blaster I guess, the torx bolts came out without too much trouble. I did pick up new bolts before hand though but had trouble finding metric bolts in my area. Ended up using a 9/16" x 4" #8 bolts to replace the torx bolt. Make sure you get some good washers too so the hex head doesn't cut into the aluminum sub-frame.

    Thanks for the write-up. Just wondering if there is any reason to not re-use your factory nuts if they are in good condition? I noticed the OEM nuts are flanged, and the Dorman ones are not.

    I did not re-use any nuts.

    Why isn't there any talk of TTY tightening?

    Because nobody cares about torque to yield bolts??

    I never replace bolts unless this is something like head bolts or something critical.

    Yes, was trying to say "never mind", but the server was too busy to log in. I see this isn't critical in this situation. Found out this by looking up replacing a Focus' LCA. Their balljoint stud is held in by clamping friction (no nut), although the video wasn't TTYing that bolt (lol). Thanks.

    bumpin this to say thanks for the write up. i sometimes wonder how much time i would have saved 20-30 years ago if i had the net back then.
    one note- the 21mm wrench makes the job a lot easier. my set skipped 21 but i managed with a cresent but would have been a lot easier with that.
    another note:
    make sure ya have all the tools BEFORE starting the job.
