I have a 2002 dodge ram 2500 diesel. I lost power steering

Customer Question

I have a 2002 dodge ram 2500 diesel. I lost power steering and brakes. First I changed the power steering pump...No change. Changed the gearbox and vaccum pump. Jacked the truck up and turned the wheel lock to lock. The steering seems to get easier but the brakes stay hard.

good evening my name is ***** ***** I will assist

do you have a hydrovac unit behind the master cylinder or do you have a brake booster???

Roy

Customer: replied 8 months ago.
I believe it's a hydrovac. Diesels don't use boosters.
Expert:  roy replied 8 months ago.

if they have vacuum pumps, some do. I thought the same thing

anyway, if you replaced the pump and still have no assist the hydro vac unit has failed. most likely has debris that caused it to fail. when you replace it flush all the lines, steering box and the pump.

The unit isn't leaking. If I replace it and the problem doesn't go away, what should I look at?
Expert:  roy replied 8 months ago.

it does not have to leak to be bad. it has failed internally.

do you have pressure gauges to verify pressure to see if the newpower steering pump is working???

Roy

Customer: replied 8 months ago.
No but I replaced the gearbox and had to add fluid afterwards while bleeding the air out of the system and it was pumping the fluid. I'm going to replace the hydrovac unit tomorrow. Hopefully that fixes it.

Hi Roy. I changed the hydroboost pump and all of the hoses. A friend and I bled the brakes and bled the steering system. Truck is still the same. I'm thinking there must be an air bubble or two locked inside the system. I have to drive the truck 100 miles a day this whole week. Hopefully the system bleeds out the rest of the air during my commute. Do you have any suggestions?
Expert:  roy replied 8 months ago.

bleeding is the same as a power steering pump. turn lock to lock to bleed the system.

That's how we bled the system. Front end jacked up. Lock to lock 40 or more times. Still hard brakes and steering
Expert:  roy replied 8 months ago.

ok, I am wondering if something got into the new pump and is not allowing it to build pressure

Roy

Customer: replied 8 months ago.
Which pump. They are all new (rebuilds). System was flushed each time. Driving me crazy!
Expert:  roy replied 8 months ago.

I understand but there are some places you cannot flush especially in the hydrovac unit

Roy

Customer: replied 8 months ago.
Any suggestions?
Expert:  roy replied 8 months ago.

try flushing it again and if it does not work, replace the pump.

the bad hydrovac most likely caused the original failure of the pump and also caused the failure of the second

Roy

Customer: replied 8 months ago.
The power steering pump is moving fluid. I'm baffled
Expert:  roy replied 8 months ago.

it may be moving fluid but it needs to push a lot of pressure. if you want to be sure, get a set of pressure gauges and check the pressure. you need about 800 lbs plus for it to work

Roy

Customer: replied 8 months ago.
I'll try that
Expert:  roy replied 8 months ago.

ok

Customer: replied 8 months ago.
I ordered pressure gauges.
Expert:  roy replied 8 months ago.
