got my Boxster back on the ground yesterday.
The driver side rear axle decided to leave the comfort of the transmission flange. This was because the mechanic in my shop did not torque the axle flange bolts with a torque wrench. But instead tightened them with one of those "L" shaped allen wrenches.
So had to install a new flange on the transmission and since I was there I installed my headers, and FVD Brombacher muffler
Also a note to ANYONE installing the cheaper axles from Pelican or any parts house. The bolts they supply are 10x50mm which is the same as OEM. BUT the axle flange is a little thicker thus a little less bite from the bolts. Save yourself some grief and possible future issues and go to Fastenal and get your self some 10x55mm bolts.
