I'm changing the hydraulic power lift gate on my Mom's 2012 GMC Terrain. The part number we're using is 23432304 and we bought it on Amazon for about $160. You can click on the link below to purchase one from my Amazon Affiliate link. It doesn't cost you more and I get a small portion of the sale, which helps me to create more content and "How To's" in the future. All in all it took around an hour. The only specialty tool i needed was a T40 Torx Bit.
