    subframe and trailing arm torque specs?

    what are the torque specs for the 2 subframe mounting nuts and the 4 trailing arm mounting bolts?

    for the 22mm subframe nuts, as tight as you can get them.

    for the trailing arm 19mm bolts/nuts pretty damn tight, but no need to over do it. They have a locking nut so you don't have much to worry about.

      as a follow up, are the two subframe nuts self-locking? Do they need to be replaced? The dealership said they would have to special order that nut. I think I remember looking it up on realoem.com and it saying it was a locknut. Can I reuse the nut that came off of it?

      thanks

        Its a crush type locknut. Go ahead and reuse it.

          The torque spec on the subframe mounting bolts is 140Nm.
          The trailing arm mounting bolts are 77Nm, I believe.
