Good Morning! I have a 2008 Silverado 5.3L with approx. 85K miles on it. Over the past moth or so I ve noticed what feels like I'm driving over "rumble strips" while coming to a stop. It also does it at a slow-roll, say around 15-20 mph. It does NOT do it when I put it in nuetral and stop. While sitting at a stop light it feels a lot more "under-a-load" than it has before too... That goes away as well when I put it in nuetral. At first I figured it was the rotors so I pulled them and had them turned. NO DICE!!!! So I went to work: -Rotors turned -Drums turned -New calipers -New brake lines -New pads and shoes -New Swaybar links -New Thottle Position Sensor (Check Engine Light fired this code) -New U Joints (Front and Back) -Tires rotated -Beers drank Dealer says it sounds like it needs the differential serviced ($189), OR the transmission serviced ($239), OR the injectors serviced ($120)... Diagnostics will cost $110 but it would be a waste since there is no CHECK ENGINE light on! Thanks, David
