My 91 240 has an annoying clunk rattle when driving slow speeds over small bumps, like a pavestone driveway for example. It has had this since I bought it. I thought it was inner tie rod ends, since the steering rack was leaking and had a bad boot. Replaced the rack with a Jorgen unit and nothing changed. While there I checked the suspension components, I did not find anything loose or worn excessively. I checked wheel bearings and they were OK. The thing I did not check was sway bar bushings or end links. Maybe those are the culprit? Anyone have any similar experiences and figure out what it was. I also checked the front brakes and the pads do not seem to be rattling.

Thanks.
