Recently my 2007 Coupe with Z51 and Paddle Shift had to go in for repairs. I was feeling a bearing vibration while driving. With my hand resting on the shifter you could really feel it. I went on line and searched everywhere for anybody else that might be having the same problem. Nothing! My car has 50,000 miles on the clock and is driven like a road queen, NEVER RACED or hammered. I took it to Harbor Chevrolet in Long Beach, CA. They took it for a drive and agreed, something is wrong! They wired the car with sensors and laptop and took it for a drive. ( I was impressed ) It was deturmined to be in the differential. They removed the differential and replaced EVERYTHING inside the case. The Ring and Pinion showed signs of mis-alignment. Took a while to order and get all the parts but results were amazing----smooth as ice! Since the complete rear carriage and exhaust were out and laying on the ground, I decided to install a new exhaust system. No installation fee since they had the stock exhaust out anyway. I installed the NXT STEP system. SOUNDS INCREDIBLE! Just a touch on the loud side when cruising at highway speed. But click into Paddle Mode and bring the RPM up and WOW!
