Well i took my car out to this club thing where we got to drive a course a few times and compete for times, well anyways it was a blast and i am going to be doing it more this summer but a couple days later i am starting to hear a creaking coming from my axles maybe i dont know much about the owrkings of cars but its when i start going forward or backwards, sounds like straining on something...anyways any guesses would be nice, anything i should take a look at and make sure it is still solid

 

Sounds like it could be the rear axle clicking. If so, there is a TSB for it.

 

a tsb for an 05?
