I want to switch to amsoil for the P/S, the humming is getting old when cold, should I use power steering fluid or ATF+4 or what?
Also I remember reading some modified one of the ps lines for better flow, is this something I can do with the pump still installed or should I pull it?

Thanks.

My CRD uses ATF4 instead of PS fluid. Check your owners manual.

Might want to fix the problem 1st.

PS noises means there is a leak allowing air to enter the system.Most common on KJ's is the high pressure line leaks and the return line has microscopic pins holes that don't leak fluid but allow air to be sucked in since the return side is under a slight vacuum when the engine is running.

Thank You, I'll get some hoses ordered then. I noticed the R/P is wet but doesn't drip, it will annoy Me when it is cold then go away once warmed up. Do I need to make any changes on the system? I remember reading about the lines being small thus causing the whine.
