I have a 98 firebird that makes popping noises in the rearend. it won't do it in town, when i'm above 55mph for 10 mins then start slowing down it pops at about 15mph and slower stopping and starting. once it sits for a bit the noise will go away... or at least till i get back on the highway..... the diff fluid does not have metal in it nor does it smell burnt... please help me as i would really apprieciate it... thanx mike
