Fresh 5W-40 oil, filters and new plugs. Best of all? New arb bushings and no more jittering steering wheel.
Because regular ForFour doesn't have arb bushing change guide, it is quite a job to do on parking slot. I'd suggest doing it at garage, takes about 0,5-1h depending on skills of the mechanic (know-how)
Rough guide:
- Lift car up (or put jacks on parking slot)
- You need to lower sub-frame with engine/transmission jack (4 bolts [2 trough wheel carrier, and 2 are plain visible) + engine/transmission support bar + steering bar (4 bolts))
- take off ARB bushing bolts (4 bolts)
- Slide old Bushings off
- Put new ones back
- Bolt everything back
Why do you need to lower the subframe? Because power steering motor is blocking access to other side. (No room to get ratched there, you might be able to do with regular wrench in painful position).
