The former USA national team captain was released by Scottish club Rangers last week and will now continue his career back in his homeland.
34-year old defender Bocanegra is thrilled to be back in MLS and is looking forward to the challenge of helping lowly Chivas get their season back on track.
"They're struggling a bit with the results on the field, but they made it quite clear to me that they're looking to turn things around," Bocanegra told reporters Monday shortly after his signing was announced.
"With me signing with them, they're hoping it's a first step in the right direction. Me coming home, which I'm very excited about, is an opportunity and a good challenge.
"I was ready to move anywhere in MLS. Chivas came in and said it was important to sign with them. They're looking to turn things around, so hopefully this sends a good message. It had nothing to do with being in my hometown. It's awesome that it's an hour from my house, but that wasn't actually the thought at all. It just ended up working like this."
