Hello i have a 2004 3.0i with 177,405 miles and still going strong!!!!!

But i recently realized that i have a lot of camber in the rear especially the left.. I know that the e53 has camber in the rear from the factory but mine is getting pretty bad?? I noticed it when i saw a e53 on the road and it looked practicly brand new and the rear barely had any camber at all, compared to mine i got to much i think?? Is there anything majorly wrong or is something just warn out??? - any responses will be gladly appreciated..
