I changed out my lift gate shock pistons this morning. It took 1 hour by my self. I watched the u-tube video on line and not much to it, just have to be careful when removing the interior panels. The local Import dealer where I bought the car wanted $700+ they said it would take 4 to 5 hours and the parts were $190.00. I bought the parts from PartsGeek.com for $97.00 with shipping and one hour of time. $600.00 in my pocket for fuel.
