Correct hydraulic oil
I just replaced the high pressure hydraulic line on my 86 5000cst and
filled the reservoir with Bilstein 2615 ZH-M oil. I have always used
Pentosin 7.1 in the past but the parts house/repair shop was out of
Pentosin and said this was the same thing.
Now I hear a low pitched growling noise when driving. I thought it
might be the hydraulic pump complaining about the wrong type oil.
The noise was not there until I changed the hydraulic line and replaced
Any help would be greatly appreciated.
