Parts: The Arnott remanufactured air struts were $460 each, and I will receive a $50 core fee refund for each, which works out to $410 per strut.

Time: He is a pro and made the work look very easy. It took him about 2.5 hours (1.25 hr each) to change both air struts by himself. I offered an extra set of hands when needed, and he never asked me for help.

It has been about 8 hours and hasn't lost air, so I am hoping this was the fix.
