My 1985 280SE euro (w126 body and a mixture of other chassis) has a terrible knocking maybe clunking sound when the brakes are applied or when i go over bumps or uneven dirt roads. I just changed my brake rotors and pads but the noise is still there. Is it safe to drive around with it the way it is?

Inspect your control rod mounts (aka axle joint support). Torn boots are a good sign that they're in need of replacement.



As far as I've learned, faulty control rod mounts don't make driving the car any less safe, but leaving it as is most obviously ruins the quality of the ride and maybe accelerates wear of front end components.

Are they also called the guide rods? And do you think the w126 part would fit my mish mosh euro Benz?

The guide rod is an actual rod that the mount cushions against the bearing bracket; the rod and the mount are separate components. The 280SE is a W126 and the guide rod mount for the chassis is universal across all models.

There are cheaper places to buy replacements online—the link above is just to give you a general idea of what the problem might be and what you will need if that's your problem. There are many DIY tutorials here and elsewhere on how to replace these yourself. It's supposedly a somewhat laborious task, but the process can be made easier with the right tools.

Most likely broken rt. and lft. away bar bushing. Cheap to buy but difficult to install. But you can do that.
