Steering Box W124

Hi there,

I noticed a lot of back lash on my steering and somehow it feels loose. Jacked up the car and noticed free play. A friend of mine told me my Steering Box is loose and there is a nut which I can turn anti-clockwise to tighten it.

Alright, since I'm gonna be getting my hands dirty and all, I'm gonna get the following items replaced:

1. Idler Arm Bushing
2. Steering Damper
3. Tie Rod End (Left/Right)

Question is, are there other parts that I should replace at the same time? Please advise. Thank you guys...
