its not gear whine, or going over bumps, its the overall sound. when im accelerating, theres no type of sound, only on the decel, its like the axles or something, its a ton of vibration, idk, i was thinking last night. I went from all blown out bushings, rubber lowers, rubber upper, rubber axle housing bushings, to, Steel uppers, poly/steel lowers, and poly axle housing bushings, and a 4.10, maybe im nott used to this? maybe this is normal. idk because i have no cars to compare to
