noisy 9" rear
 

i have an new 9" rear bought from Detroit Speed and its very noisy when i drive on the highway with little loud on it. The rear have an 3.70 gears . Is it some one who can say whats wrong with the rear.

What type of gears are you running? Also, what type of traction system are you running? Certain gears are noisier than others.

hello iam not shore i bought evrything from detroit speed but that was with alu housing and 3.70 gears

You may need to reset the lash on the gears or you could have some bearings gone bad or even a busted ring or pinion. I am very familiar with rear end noise I've gone through many of them on many vehicles. :lol:
