I don't remember the specifics as it was 10 years ago. But probably around 225k mi on the mileage when I bent/replaced the arm. I did replace the bushings in the control arm; this is easy when the replacement is sitting on your garage floor.

You might as well replace your subframe bushings/diff mount too as you will have to partially drop one side of the subframe in order to get the trailing are bolts out (at least this is how it works on the 126). If the subframe bushings are original, you will be very pleased with the improvement in hiway driving.
