I have a 2005 LL Bean Wagon I just bought with 225,000 miles on it. The rear hatch pistons are failing. Sometimes they work and other times I get hit in the head while hatch falls. Does anyone have a good set out of a 2005-09 OWB they are parting? I called Advanved Auto Parts and they say they can not get them as aftermarket. Does anyone know if this is a Subaru OEM ONLY part? Know where I can get them cheap? Thanks!
