Trying to renew front suspension

I'm not sure this has been covered previously. I have a SE 4.5. It drives fairly well on smooth tarmac but groans and clonks on rough surfaces and on braking at low speeds.

Shocks are new, Bilstiens. I have no problems with alignment or brakes.

I think my bushes and ball joints are bad.

Is there a kit I could get to get it back to spec or does anyone what to replace by item and where to get it.

W108s don't have ball joints. They have king pins. King pin kits are available everywhere.

If they have not been regularly greased, they may be difficult the first time. As said above, 14 fittings on the front end. one on each control arm bushing (4/side), one at the top eccentric joint on each king pin. One at the bottom of each king pin, and one on each king pin itself.

My W108 had sat for many years so it took a bit of work for mine to take grease again. I removed each fitting and soaked them to ensure they would take new grease. I then had to soak each grease point with penetrating oil to loosen the old grease (sprayed through the fitting hole). Let that sit a few hours, put the fittings back in, try like heck to get them to take grease. If you do need to do the penetrating oil method, make sure you put plenty of grease through the first time to flush all the oil out.

At the end of the day, I salvaged the king pins, but had to put in new eccentric kits. Major PITA.

Most grease brands are incompatable with each other so its best to stock one good brand and flush out the old grease in the joints.
