Hi, Thanks for let me join. We have two 1st gen Vibes, both automatics. Just found out the latest one has a bent rear axle beam. The previous owner said it was his mom's car and had been side swiped-drivers side. Everything appeared fixed and it seems to drive OK but we noticed bad weird rear tire wear-inner edge on both. Now the question in my parts search-how much compatibility between the Vibe and Matrix? It is a base model, FWD Vibe. I plan to replace the whole rear axle beam assembly-brakes and all. It get new struts and bushings. There are alot more Matrix cars available for parts. Also, this is 2005 Vibe, is 2003-07 the range for parts? The previous owner's mom used this as a work vehicle around her place, <90k miles so it's worth the repair. Thanks.
