On 4.6 and 4.8is applications the torque of wide open throttle will wear out rear suspension parts at a higher rate than any 3.0 application. Uppers are long gone at 80-K. Ball joints might as well get replaced as they are simple and removes any worries. Look for any premature wear on the lower suspension arm inner bushings coming from owner/road abuse. Making a big fat BMW handle comes at a cost of replacement parts.
Take a ruler and confirm that your rear subframe is centered.
Replace everything suspect and you will have lots of driving enjoyment.
