I put in a set of the new richmond 4.11's along with Jre posi mod and billet caps a month ago. I am a 23 year master tech and am very anal about my work. They were pretty loud from the start..I think the pfadt diff bushings and bmr rear cradle bush don't help...I spent a long time setting them up and the pattern was as good as it was going to get...I had several people look at the pattern also because I wanted them to be perfect after hearing all the tales of noise on here..some have no noise some have a little...I have a lot of whine on acceleration..nothing on decel..just on accel around 40 mph and up...I am going to pull the cover and check for pattern wear once more...but am thinking of switching to the aam 3:91:'s..this whine is killing me though..it is really loud ...I have to turn the stereo way up to not hear it...I think I got a bunk set of richmonds..
