1990 560sel has a rattle when you apply the brakes at 30mph or higher sounds like on the drivers side, it will also make the same sound at 70 moh going around a curve in the highway not a sharp curve just a bend in the road. is this the guide rod mounts going bad or ball joints?

rattle when slowing down..usually I hear guide rods @ low speeds when applying the brake...ball join Have you looked at your upper and lower control arm bearings?

Either way it sounds like the front end needs a pretty major overhaul!

have done the tie rods and center link. the other control bushings are in good shape looking wise. if guide rods dp you do the bushings are due the repair kit they look quite different
