3 hours seems high for a shop -- I'm hoping to be able to do this in 3 in my driveway.
If I remember correctly, in the past when I unbolted the control arm from the ball joint (the 3 nuts underneath) the control arm didn't drop low enough to come totally clear of the ball joint studs (they are pretty long and perhaps designed this way on purpose as a safety feature). This could introduce some complication. Note: the range of motion of the control arm is restricted by the subframe in which it is mounted.
Have any of you guys run in to this during the install?
