question about maintenance
 

i have a Ph1 1.6 8v saxo and i really want to change the powersteering and transmission fluid.

For powersteering i bought Kroon Oil ATF DEXRON II-D 1 Litre
For the gearbox i bought Kroon Oil Gearlube RPC 75w/80w 2x1 Litre
are these the right ones and are these enough?

How do i flush my powersteering fluid? it is pretty dark and it is on its minimum line.

My gearbox/drife shaft makes a sound when my wheel is turned.

Gearbox is correct,power steering I got Dexron type ATF.
Easier to just replace the driveshaft,it's 26£ from eBay.
Remove the hoses/pump to drain the old fluid.

disconnect the hoses from the powersteering pump and turn the steering lock to lock a few times should flush most of it out and you'll probably have to take the pump itself off and empty it out, good time to give it a clean up anyway.

a drifeshaft cost new here around 120$
About the soud u see in my youtube video, what could me the part that is making this sound and why?
Does it perhaps need to be lubed again

Fixed it by replacing the left drive shaft, also replaced the (bearring suppose which is in the opening of the axle on the gearbox) in the gearbox.
