Part and instructions on replacing 97 E320 Power Steering Pump?

[MarkR]

Have a 1997 E320 and I think I am in need of replacing the power steering pump. It growls a bit. Can anyone guide me to the best place to get this part and then a place to show instructions on how to change it out? Thanks!

dont replace the pump yet. i had the same problem
with the fluid indicator at mid. try topping up more steering fluid up to max.
the problem may just go away.

hope this helps
