    I recently replaced my lower ball joints and found something interesting/scary. The Toyota bolts are extremely soft and I wonder if they are causing people to have failures. The service manual states to torque the 8 bolts (4 on each side) to 59 ftlbs. Good luck with that, I ended up snapping the head off of one completely, and I took the rest out and all were severely stretched.

    The bolts are part numbers 9011910933 (these go over dust protector holes) and 9010510505. Having stretched bolts in a critical suspension component is a major safety hazard and a disaster waiting to happen. I couldnt torque them down past 40 ftlb's without them stretching, so that is what I did with a new set of bolts.

    To anyone doing their lower ball joints, watch for stretched bolts.

    Are you sure about the 80 lbs? I think they are more like 56.

    Sorry youre right. I torqued to 59 ftlbs not 80 I re-read the manual again when I posted and saw 80nm. The bolt head snapped at 56 ftlbs. I made the correction in the original post.

    I'm not right often, I looked it up on an 05-06

    Connect the lower ball joint with lower ball joint dust cover protector to the steering knuckle with the 4 bolts.

    Torque: 65 N·m (662 kgf·cm, 48 ft·lbf)

    We may be talking different years. I only remembered because I did them this year and thought it was low. But I've also learned I tend to over torque if I don't look it up.

    Loctite and hand tight with a 16 inch socket wrench is what I do. Although loctite isn’t needed with the natural corrosion my vehicle gets.

    Little niggling detail to point out here, if your copy/pasta from the owner's manual is correct.

    OP is saying he torqued to 56 ft·lb. The manual states they're to be torqued to 65 N·m.

    So yes, it makes sense they would snap or stretch well into the 50s of foot-pounds. 56 foot pounds is nearly 76 Newton meters! Already tighter than OEM spec. [Edit...] 48 foot pounds would put you on target @2uzfe2000

    If so, this is a classic mistake to make. And there are some places - as I think @FirstGenVol found out with his transmission pan bolt(s)? - that Toyota flip-flopped the two, which doesn't help.

    The 2000-2003 service manual asks for 80nm.

    Is it potentially a part change issue? Or a misprint in the manual?

    Everyone thinks I broke my trans pan bolts. :notsure:I did not. I just stripped the drain plug. Manglers don't lie. :hattip:

    Hence the (s) at the end of bolt(s). Drain plug would be "bolt". Pan bolts would be "bolts". "bolt(s)" covers both bases.

    But am I wrong, was the torque value in the manual incorrect?

    Someone at Loctite apparently earned their PhD with the "thesis" attached. Fascinating reading (if you have all day), and way more information than any one human needs.

    https://dm.henkel-dam.com/is/content/henkel/LOCTITE-Threadlocker-Manual

    The Internet suggests that torque should be REDUCED by ~ 20% when using thread locker to prevent the elongation of bolts due to over tightening. Section 6 in the Loctite Manual (pg 30) addresses this.

    That said, however, OEM bolts appear to be factory coated with Loctite (or some such thing), so I'm confident that their torque recommendations reflect this. If you ADD Loctite (or anti-freeze, et al)...beware.
