The most likely cause of these problems to both happen at the same time would be a failed power steering pump; I believe the PS pump pressure also operates the power brake assist on the turbo diesel models.
If the belt came off it could also cause similiar symptoms, but your alternator is also run by the same belt so your battery light would be illuminated on the instrument panel if the belt was the source of the problem. If it is charging, then you should check the power steering pump in the morning when it is daylight.
Okay...Let me add this to ya,
My Rig has 245K on it, whatever it is that is causing the problem is SEVERELY LEAKING under my truck, spilling down on the front axle....The PS and Brake reserviors are COMPLETELY Full, The brake pedal was so rigid that I couldnt get it to go down for the life of me....It was almost like I was trying to turn a Tank When everything Crapped out...The Belt Didnt Slip at all.Its still on the Pulley's....
Still think its the PS Pump?? NOt a potential Vacuum leak or something like that?
The System Runs off the PS Pump...As Far as I've been told.
The one thing that is shared here is the power steering pump; a failed pump will cause both the power steering and the power brake assist to stop working at the same time.
You stated that whatever is causing the problem is also causing a SEVERE fluid leak under the truck; this is probably power steering fluid. Have you identified the source of the leak?
Sounds like you either have a bad pump, or a leak at the power steering pressure hose where it attaches to the pump.
If you replace the pump and/ or leaking hose, it should correct both of the problems you are having.
Here is the procedure to replace the power steering pump and purge the air from the system. I was not able to locate any illustrations that I can upload, but once you get into it this really isn't that complicated of a repair job; I don't think you will have any difficulty.
Remove and cap steering pump hoses and vacuum pump vacuum line
INSTALLATION - DIESEL ENGINE
WELL....The Problem Is, I Dont Beleive it has a Vacuum pump at all...So, Im not sure how this applies to my Ram...Do you by chance have a Diagram on it?? I Can read and understand the removal, But I Want to See a picture of it...The steps to remove this thing sound like a Pain in the Arse!! So I'm NOT looking forward to doing it...But a Diagram and or Picture would SERIOUSLY Help!
I am afraid the manuals I have access to do not contain any pictures or diagrams...
If yours does not have the vacuum pump, then you do not need to worry about that part of the procedure. There were 2 different VIN code cummins diesels used in that model year pickup, that could be the difference.
If yours does not have an attached vacuum pump, then it should be basically the same pup used on the gas engine trucks, and should be much easier to change. The only difference is you will need to purchase a power steering pulley remover and installer tool, to swap the pulley from the old pump to the new one (and to remove the pulley to access the mounting bolts located behind the pulley).
I have found a picture of the conventional style pump; if this looks like yours then you do not have a vacuum pump attached.
If you do not want to purchase the special tools needed to remove and install the pulley, you may want to consider just having your mechanic perform the installation; it is usually pretty inexpensive to have done since it does not take very long.
Ha! Mine is the VIN "6" WIThOUT the high output Motor...AND if there was a mechanic close, I'd already taken it to them...Unfortunately our Fleet Mechanics that service all of the Sheriff's Office Vehicles can't work on it for me, Otherwise I would have left it at the office!
I Dont understand why I have to pull the Pulley out though, And If I do...Accessing the front of the motor (with the fan shroud and radiator right there) is going to prove to be even harder than I expected...Can ya elaborate on that side of it??
I hate to keep bugging you with tons of Questions, But I like to be prepared BEFORE I start busting my knuckles on something that could potentially be VERY straight forward and easy to replace...
Okay - Took your advice and had the Power Steering Pump Replaced, Turned into be a Problem with the Vacuum Pump...Now I dont know why Dodge STEALERSHIPS have to be so expensive, but 1500 bucks for a New Vacuum pump was a bit RETARTED....So I bought one for a little shy of 400 through Napa...Replaced That and Bolted everything back together...
and I STILL dont Have any PS or PB....Does The System Need to Prime at all, Or Am I missing a simple step to make this bloody thing work like it Used to?
