Getting vibration at 100mph
I recently had 4.11 gears installed in the stock 10-bolt, they were dead quiet for the first 700 miles, but have recently developed a whine when coasting (letting off the gas at speed) - It's a constant almost siren like noise, the pitch getting lower as the car slows down to a stop.
Could these be related? I read somewhere that some cars have vibration issues with the stock driveshaft and steeper gearing, am I looking at replacing the driveshaft? And if so, suggestions for a company to go through?
Thanks much!
Robert
At the same time have the universal's checked etc. for the cause of the vibration.
Thanks for the advice
