After I repaired my issues still hearing the same problems

IF the differential and axles were repaired correctly and in good working order, you way want to look at wheel bearings/hubs, brakes, tie rod ends, sway bar bushings, etc. Anything that moves can make noise, and you could be hearing more than one component. For instance, a wheel bearing could be worn and making a grinding noise, and the upper ball joint could be popping when you hit bumps. Best to have a professional inspect your steering/suspension components, and re-inspect the differential and axles. http://repairpal.com/bmw-within-10-miles-of-red-bank-new-jersey-07701
