W210 Estate suspension knocking

[russo79]

Hi

I recently replaced the spheres and hydraulic lines on the rear of my E300 TD estate. I was very bouncy but after bleeding the system its now quite smooth but knocks when I go over any bumps. I've changed the front subframe bushes as well as the bushes on the rams/shocks.

Any ideas what it could be..? I've had the wheel off about 10 times now trying to find out what it is.

Suggestions appreciated.

Thanks

It takes a little time to get the air out of the self-levelling system. Hopefully the knocking will disappear soon...

I don't know how much you've already checked.
Front drop-link bushes are a common knock on the suspension on these cars.

The front anti rollbar bushes used to knock on mine and were replaced twice in the 40k miles I had the car.
