Picture of w220 front suspension on WIS?

[leicschris]

Hi All

I have a couple of suspension issues on my 2001 S320cdi which I need to get sorted asap.

It was reported to me that front lower ball joints were worn to excess and yesterday whilst changing the oil I had a look when the car was up on axel stands.

There appears to be two 'arms' going to the bottom of the wheel/hub assembly and on the drivers side the rear one closest to the bulkhead has a definite faulty balljoint, and on the passenger side the faulty joint appears to be the front 'arm' closest to the grill.

Does anyone have a good WIS picture of this part of the front suspension so I can understand which parts needs replacing, and the best course of action to replace them.

I see the rear arm has three joints/bushes so it may be better to change the whole arm and replace three rubber items rather than just one ball joint, if the cost is not too prohibitive.

Thanks in advance

Chris

Hi

Thanks that's perfect

Looks like I need a new lower arm and torosion bar on both sides

Is it better to change the full arms or just change the ball joints/bushes

Thanks

Change the whole arm. The joints are part of the aluminium arm.

The pic above does not point out the front lower ball joints. They are at the hub end od the lower arm and need to be pressed in and out.

Olly's the expert on these things. Item 10 on the parts diagram. Not very expensive so worth renewing both sides while you have the suspension in bits anyway. With suspension its always best to replace things in pairs as it helps maintain suspension compliance/balance " side to side.
