[QUOTE="TonyG2, post: 15015751, member: 56468"] I'm reviving this old thread again to let people know that today my trutrac noise disappeared. From day 1 when it was installed, it sounded like someone was shaking a box of marbles whenever I let off the gas and decelerated. Two things were modified, so I don't know which one was responsible (or if they both were): (1) pinion seal was replaced -maybe it was the pinion seal itself or one of the other things that gets touched during this job (2) UCAs replaced -I'm not drag racing as much in my "old age," so I switched from hard core UCAs (Baseline) with heim joint/spherical bushings, to more normal UCAs (Steeda) with their 3-piece poly bushings. I know that the spherical bushings in the Baseline UCAs were not the source of the noise, b/c I had them when I had my old tracloc and there was no noise. The noise started when the truetrac was installed. I suppose that it's possible that the solid metal bushings were transmitting the noise from the diff. Now, the noise is absorbed by the softer bushings. But it is a dramatic effect. I can't believe how quiet the car is now. I can hear the radio, and I don't sounds like a Sherman tank coming down the road (as someone posted above). I can enjoy driving the car on the street again. [/QUOTE]
