Rear end noise

[ajt9229]

I just put in the sub frame and differential MM bushings and now driving between 40mph and 50 mph I get a high pitched noise.under a load it stops. Im figuring the angle is off? How do I correct it or get it corrected?

Thanks

Are the mm bushings aluminum? You might get more responses if you posted in the right section, this belongs in driveline.
