When I come off the freeway after driving for a while (5-10 miles) sometimes I hear a clunk that sounds like it's coming from my differential. 95% of the time i drive on surface streets so it doesn't happen often, but it does happen and worries me that something might be broken. Any help as to what it might be? I am going to put the car up soon to install my alston sfc's so any info on what to look for would be helpful. thanks.
