Be very careful on those rear studs. I had my lug nuts overtightened at a tire shop (they used a torque wrench, but their spec book had the wrong torque) and they damaged 2 studs. I pulled out the rear axle and brought it and 2 new studs to a machine shop recommended by the Mitsu dealer. The machine shop proceeded to damage the bearing and bearing housing, and break one of his own tools trying to press the retainer off. After waiting 1 1/2 weeks for the replacement parts (and leaving my wife & I sharing one vehicle) they tried to charge me for the parts they had damaged and had to replace. I explained that the FSM procedure is to cut off the retainer rather than try to press it off, and I wasn't going to pay for their mistake, especially since I had already been without a vehicle for 2 weeks because of them. I ended up getting the whole thing for free, but it was a major pain in the ass. Hopefully you don't end up needing to replace the studs, but if you do, pre-order the retainer, then make sure the machine shop is totally clear on what they need to do to replace them.
