You have the classic symptoms of a worn out MCV pump. You may as well just pull the MCV assembly. The pump is mounted on the inside of that assembly. You can check for blown O-rings between the pump and MCV and the MCV and center housing. If the O-rings are OK go ahead and replace the pump.
An unseen side affect of this problem is that you are starving the range transmission and ring gear/pinion of lube oil. The excess oil from the MCV pump goes through the oil cooler and then to the rear frame for lubrication there. The steering gets priority on the first three gallons of flow. If you do not have enough to satisfy the steering demand there will be no flow to the rear. Running with a weak MCV pump can lead to range transmssion and differential failures.
