Originally, the satellites were attached to the Star-48 Solid Rocket Motor (a Morton- Thiokol product). The motor in turn was attached to the PAM-D spin table. The spin table is what gave the satellites their spin in the cargo bay before deployment. It consists of a large bearing and a motor. Now that the solid motor has separated from the satellite, there aren't the right bolts to tie down the spacecraft. Think about it, do you want a 1200 pound satellite rattling around the cargo bay while performing 1.5 gee reentry, 75 degree banks, etc.? You want it bolted down good.
