Disconnect battery and release serpentine belt, releasing the tensioner bolt. Use a puller to remove the pulley on the poower steering pump assembly.
There you will find the hydraulic hoses, it can be removed using flat screwdriver. The return line is located on the right side. The high pressure line is the one attached to to the pump. You will need a 16mm wrench to undo it.

Power steering hose keeps breaking, even when replaced by high pressure hoses. Replacing rack and pinion does not help either.


A bad seal in the rack and pinion would have caused low pressure from fluid by-passing the seal. This also would have caused noticeably increased effort to steer the vehicle. Excessively high pressure would indicate an issue between the power steering pump and the rack, and since the hoses have been replaced I would focus on the pump. PS, find a real mechanic, not a parts changer.

Fix power steering leak


You need to determine where the leak is originating. The possbilities are:

1. Leaking from the power steering pump.
2. Leaking from the high pressure hose at the steering rack
3. Leaking from the return hose at the steering rack
4. Leaking from the steering rack boot(s).

Once you find the leak source, replace that component.

The steering is hard to move and the steering warning light is on. Please let me know what to do I need to urgently resolve it.


The servo unit on the steering has failed . Look inside the engine bay for oil leaks - if none are present then the entire steering rack will have to be replaced - the internal seals have failed.

98 Ford power steering keeks bursting the high pressure hose.


it sounds like it is pumping too much pressure, you need to take the vehicle to a power steering specialist & have the pressure adjusted otherwise you will just keep bursting hoses or the seals on the steering rack......hope this helps.....cheers.

Power Steering Recently my power steering pipe blew and started leaking due to it comming in contact with the engine. Is it possible to remove and replace this pipe or is it a sealed unit to the steering...


if it's the low pressure side i'm sure a mechanic can replace just the broken part. if it's the high pressure side, best off just to get a new hose. if not, the hose is likely to leak again on the high pressure hose if the unit isn't replaced.
