I posted a while back about a squeeking that was driving me bonkers! Well i finally broke down and couldnt figure out wth was wrong with it so i took it into the shop. Got it back today and they said they "beleive" its my rear gears, i've never heard of rear gears squeeking from stress. Its just odd to me cause the noise comes from the passenger side. When i roll up that window its gone completly. I tried replicating the sound when i had the car on jacks but got no results cause apparently there wasnt any stress on the gears. So now..its down the this, i spend the money to replace them and risk that not even being the problem. If i was to replace them would it be better to get 3.55's or 3.73's since i have a new motor on the way and a F/I kit in the garage, or just go buy another set of 4.10's? I have no idea how the gears were installed cause they came with the car when i bought it and it made me wonder cause the kid had no idea what he was talking about.
