Before you start throwing parts at the truck, how many miles on it, do you have ACE and when did you flush "ALL" the fluids?

 

Hi Mike,
Don't have ACE.

Tried to change the transmission fluid by
draining the pan, starting up the rover, drive,
drain pan again.
Did that 4 times.

I have a transmission filter on order and will change that when it comes in.

Miles: 98,000

 

Just got the new power steering pump in.
After doing the head gaskets, removing the pump was part of the job, so
it was not too bad of a job.

Much easier then the Discovery I power steering pump.

I got as far as putting the belt back on.

I have yet to add power steering fluid and try it out.

Any ideas on how to bleed this pump?
It was a bear on the Discovery I when I did that.

OK, while fresh in my mind - here is how to change the Discovery II power steering pump.

1) Remove the protective belt cover protecting the alternator - take out the two 10mm screws.
2) Remove the fan. This is tricky. Use a large crescent wrench. Jam in a screw driver between the crescent wrench and the bolts on the water pump pulley. With one hand hold the large screw driver. With the other hand, hit the crescent wrench TO THE LEFT. The fan MAY finally loosen. Remove the fan.
3) Remove the two phillips screws holding the cowling to the radiator. Remove the cowling.
4) Remove the MAP, the air filter box top, the pipe to the intake plenum. Set on top of the intake manifold to get it out of the way.
4b) Loosen the 3 10mm bolts on the power steering pulley.
4c) Remove the belt. Use a breaker bar and the 15mm socket. Put it on the pulley nut of the tensioner and rotate the breaker bar clockwise. When the belt loosens, take it off the pulley. Remove the belt.
5) Remove the AC grey electrical plug
6) Remove the 4 10mm bolts holding the A/C compressor.
7) Set the compressor into the air cleaner box.
7a) Use a 16mm wrench and loosen the high pressure line to the power steering pump now.
8) Remove the top 10mm bolt on the top of the holding plate
9) Remove the 3 13mm bolts holding the holding plate to the engine.
10) Remove the 13mm nut from the holding plate above the power steering pump.
11) Remove the nut holding on the two pipes.
11b) Remove the 2 10mm bolts holding the power steering pump in. These are to the right and left of the 13mm nut.
12) push the two pipes to the side.
13) Remove the whole holding plate and the power steering pump with it. There is a long stud - keep sliding forward.
14) Pull hard on the power steering intake hose from the holding tank. Twist and pull - it will finally come off.
15) Remove the high pressure line now with the 16mm wrench and then your fingers turning the nut on the high pressure line. Note the "O" ring.
16) Use a hammer and carefully hammer out the old pump as it is in via friction.
17) hammer in the new pump.
18) Put on the feed line from the holding tank to the pump. Just push hard. You may want to cut the pressure clamp off and put on a typical screw type of clamp.
19) Thread in the high pressure line. Note the "O" ring.
20) Slip the assy back onto the long stud.
And, now put all the bolts back in and reverse the steps above.
21) This part may be the worst - Fill the system tank and bleed the PS pump.

 

How are those reversed window switches working for you?

 

Hi Slang,
As for the window switches - I can't remember which one does what ever.
I just try one and then the other.
I did reverse a bad switch after taking it apart. I put it on the back windows.
And, now it does not work sometimes. I need to get a new switch.

Well, I got to thinking..
The Discovery I power steering pump is mounted on rubber I think - inside
of a small cavity.
The rubber would eliminate some vibration of the pump.

The discovery II the power steering pump is mounted via two long bolts
right onto the large holding bracket which goes into head and the block.
So, the noise is transmitted easier.

I am going to bleed the pump by loosening the high pressure line until I get flow - then tighten it up.

The bleed screw on the steering box is really rusted and may snap off.

 

Finished the power steering pump.
Did not have to bleed it.
The pump just started to pump.
As all the fluid was swirling in the power steering tank / bottle as usual.

The Power Steering noise at idle may be 1/2 of what it was.
But, maybe not.
I really can't remember.

I pretty much spent $320 and shipping on a new Allmakes power steering pump- for nothing. Just to try to kill off a noise that is still there.

Maybe the noise is better. Just can't tell. I can still hear it.
Maybe it is 1/2 as loud now.

Someone will get a cheap used OEM power steering pump from me.

Oh well.
Now onto changing the transmission filter.

 

Jfall, did you ever figure out how to resolve this issue? I've started noticing the whine myself on my 2000 Disco (and it's starting to haunt me...I feel like I can hear the thing when I'm nowhere near the truck). Seems like the PS pump replacement wasn't the final solution - did you come across anything else that seemed to work?

Thanks, and appreciate all the detailed responses!

 

Never solved it.
I have 105,000 miles on the Discovery II now.
It runs perfect. Still makes that whine at idle.
I don't like the whine and changing the power steering pump did not solve it.
I did put up a video of the whine..

I guess I could diagnose it again.

Here is the original video.


Rover almost sold today. But the guy flaked out.
I would miss the darn thing.
Maybe I am not meant to sell it.

 

Did you try replacing the bearing on the idler pulley? The 80mm pulley by the PS pump uses a 6304 bearing. Its held in by a snap ring.
