1991 LS and the power steering bump is very loud. Still works great. Will flushing the Power Steering Pump solve this? Suggestions?

1991 LS with less than 160k miles and my transmission makes the car vibrate when at a stop signal. Place it in nuetral and the vibration stops. It only seems to vibrate after it's warmed up. Had the trany flushed about 12-18 months ago. Suggestions as to why it's vibrating and the best solutions to solve the problem?
