You might need to adjust your backlash to quiet it up. Mine is loud as shit with my TRD 2way but I have alot of backlash. For the price you pay for a Weir diff you can just get this Club4AG Forum Topics: ford 8.8 fabbed up and ready to kill (who wants one?) and it will hold more power with lots more aftermarket support. Im fabbing the exact same thing for mine and I'll prolly only have $500 out of pocket after selling my Diff. Thats with Ford racing 4.10 R/P, Eaton helical LSD, Moser 31 spline axles shortened with 4x113 bolt pattern, Wilwood DynaPro 2 piston calipers, and Moser C-clip eliminators.
