So my power steering is completely DEAD and I have a couple questions:

1) How much in total can I expect to pay for a new pump installed from the dealer?

2) On a scale of 1 to 10 how hard will it be to replace the P/S pump yourself?
I do oil changes, brakes jobes, I changed my last c-class springs my self and lots of other stuff like that to basically avoid the dealer at all times...

pump not sure how much but i know it easy to do i guess for me being a tech it easy ill do it in 1 hour but it pays 3 hours to do it may cost you $900 with labor or if you live in nj i can do it for you

Quadcammer

pump is $391 at parts.com

Shouldn't be too bad to replace. You have the reservoir, the mounting bolts, the return hose, and the high pressure feed hose.

First time out, shouldn't take more than 2-3 hours.

damn! Took me 1.5 hours to take it out... it was fairly simple I was surprised damn these cars are really simple to work on if you really know what you're doing...



Now to wait until Monday to go buy the new pump...

benz_addict

all the stuff that came out... including the belt but it's not in the picture

benz_addict

just one stupid question guys...
1 Liter came out in total when I drained the system, now when I'm pouring in the new fluid do I pour it in with the engine started?
thanks guys

No.

Upon installing the new pump, I would fill up the reservoir and then spin the pulley by hand.

Then start the car but do not turn the wheel. Let it run for a few moments, then shut down, check level, and bring back up to max line.

Then start it again, and turn the steering wheel from lock to lock several times to remove any air bubbles.

Once thats done, top off the level, and you're done.

You may also want to check it a few weeks later to make sure you have no leaks and the level is the same.


now, in order to make this a helpful tech post for people, can you post up the exact symptoms, and then the procedure you used to remove the pump.

Thanks.

Thanks Oliver for the answer. The symptoms I was experiencing was steering wheel was hard to turn sometimes with grinding/whining noise. This was only at cold start during the summer time but I ignored it. Vibrations in the steering at highway speeds and the steering started to get harder to turn lock to lock over few months.

Remove/Install of Power steering pump(direct from WIS):
1) Remove poly-V-belt
2) Suction off oil from reservoir
3) Pinch off feed line from reservoir
4) Detach return line
5) Remove reservoir
6) unscrew high-pressure stretch hose
7) detach high pressure hose and suction line from power steering pump
8) detach power steering pump. 2 10mm bolts on the pulley side and 2 bolts behind
9) detach reservoir (clipped to the pump)

also the WIS didn't state the GROUND connection from the power steering pump... you will also have to remove the ground wire 10mm bolt.

btw I'm surprised no one noticed the AMG airbox haha

There is a new part number for the 'O' ring... used to be copper now being replaced with a rubber ring. Usual suspect for fluid leaks..
# 000-466-18-80 list $1.99

Quadcammer

good info, thanks.

And yeah, I noticed the amg airbox but Im not sure why is a good replacement aside from looks.

Oxygen

Nice! Thanks for the step by step guide.

Next we need someone to do a DIY replacement for the ABC tandem pump..

I noticed you went back to smaller wheels.. Is that just a winter setup?

I was actually seriously considering going back to 18's on my car.

benz_addict

Yeah my winter setup, it's 17" but damn looks so small LOL

benz_addict

yeah picked it up from a salvaged SLK55 for like 30 bucks
