Power steering issue. Need expert help.
Hi all,
I really need help with steering issue.
2000 ML55 167K miles
At low speed under 5mph, My steering has almost no power assist. It becomes very hard to turn. Making parking very very difficult.
If I put the transmission in neutral or park position and rev the engine and the power assist will return. so it seems that the pump need an extra 500rpm of engine speed to operate. At Normal driving speed the steering assist operate fine.
Rack was rebuild 9 months ago,
No Power steering fluid leaks.
Hose recall done over 12month ago.
Steering pump whine is at a normal level not noticeable until the steering wheel is fully turned to it lock limit.
Am I looking at a new Pump? or another Rack rebuild? TIA for any tips
