I have a 2013 XC-60 with the electric tailgate struts. The original ones failed a little over a year ago and I replaced them with new OEM parts. Last week one was locked up in the extended position and I had to remove it and cut the wires to get the trunk lid to close. The other one seemed barely operable. Ultimately, I hacked that one too. (I use my trunk a lot). At $245 each, I would rather go to gas struts that are manual. Has anyone found a source that fit and work well? I tried a set from BOXI LIftgate and the socket was twice the size as the knuckle on the car.
