Default Rear suspension, lateral movement

Hi:

I just bought this '97 SSE three weeks ago and love it.....my fourth Bonneville.

While driving two friends home from the airport with luggage, considerable lateral movement when going over bumps at 65 MPH. Wondering if it could be rear sway bar bushing or.....I solicit your expertise.

Thanks!

you mean the whole car is moving side to side, just parts, any noise?

it appears to be a quick side to side movement over a bump......maybe I'm being too particular, but my '98 didn't do that, and my sense is the rear struts are newer on this car. Air pressure in the rear tires is about 1 lb under spec.....so, maybe it'* not a big deal. Love the car!!!!

it should feel as planted as any car. you dont normally see issues with sway bars on those, just the front and it would be a different feel. seems to me like something is wore out, shocks, bushings, something like that. you have to keep the tires at proper and even pressure too obviously, they are a big part of the suspension and feel of the car.
