Question about 2006 Buick LaCrosse

Power steering works well but sometimes doesn't work at all

2 months ago I had a leak in the power steering hose assembly - it was replaced - now for the most part the steering works fine, but occasionally it does not work at all. Usually when power steering is needed the most, parking. What could be causing this?

It's been a while since i messed with power steering... check the fluid level ensure it is correct. if so, attempt to bleed the system... air could possibly be causing the problem. to bleed the system turn the wheel to each extreme back and forth a couple of times over. hopefully this will resolve the issue. if not.... best of luck to you...

Power steering fluid leaking on 2002 pontiac grand prix


OK you know the problem but is it something as simple as replacing the Power steering hose or as complicated as also needing a new power steering pump also? Look at where its leaking to determine what needs replacing. Remember it just takes a little time to determine where its leaking. If you find that its not the hose leaking but its the power steering pump then follow these easy steps and save $100s doing it yourself:
1 Remove the negative battery cable with a wrench and place it aside. Remove the upper strut housing tie bar if necessary for access. Remove the power steering serpentine drive belt and electrical plug on the TFE off as applicable. Remove the lower bolt from the mounting bracket using a socket and ratchet if necessary for access. Take off the inlet and outlet hoses from the power steering pump. Remove the reservoir hose only on the supercharged engine. You will need a flat-head screwdriver for this task.
2 Place the power steering pump pulley so the bolts can be accessed through the hole in it. Remove the mounting bolts, using a socket and ratchet, through the hole in the pulley. Take the power-steering assembly out from the bracket. If necessary transfer the pulley to the new pump with a pulley puller.
3 Replace the power steering pulley assembly before you install the pump using the pulley-install tool from your kit. Start the power steering inlet hose connection to the pump by hand. Replace the power steering pump assembly to the engine. Replace the lower bolt first, making sure the hose and heater pipe have enough clearance so they do not touch. If the two rub together they will make noise after the installation is finished. Replace the outlet hose to the pump, directing the hose under the engine harness and the heater hose. If the engine is supercharged it will be necessary to connect the hose from the reservoir.
4 Torque the power steering gear inlet hose to 20 foot-pounds and the hose clamp at the pump to 15 inch-pounds. Torque the pump mounting bolts to 20 foot-pounds. If equipped with a TFE pump, attach the connection. Replace the power steering drive belt or serpentine belt if you removed either. Replace the upper strut tie bar and torque the nuts to 18 foot-pounds. Replace the negative battery cable and fill the power steering reservoir with fluid. Bleed the steering system by starting the engine and turning the steering wheel right and left until all the air is out.

Power steering leak on 2003 CHEVY impala V6 3.8


When a power steering pump begins to fail, it's best to replace the pump and both pressure and return hoses to this system.
Recommend you replace this as soon as possible because it could eventually cause damage to your steering rack and pinion.

Power steering fluid leak back side engine in the middle of van


I just repaired a leak in my 1995 Windstar power steering system. The leak was toward the back of the engine but more toward the right (passenger side) of the car. There's not much clearance so I had to jack the front end up just to be able to look underneath. In my case the rubber hose had come off the metal tubing portion of the high pressure hose near the right wheel.

Fortunately, it had a screw type hose clamp, and barely enough working room, that allowed me to reinstall and tighten without having to remove the hose assembly. Yours sounds like there may be a break in the metal tubing, in which case the hose assembly would probably need to be replaced. Hopefully not.

Another thing that may come into play is whether the leak is on the high pressure side or the low pressure side. It seems that the high pressure hose assembly is long and winds in and around the engine. Probably a real dog to replace. Bottom line is you need to locate the leak and that will determine which hose it is and whether you need to replace or not.

I realize that this question is a few months old and has probably been corrected by now but, for others who may experience similar difficulties, have confidence, power steering systems aren't all that complicated and, usually, are not too difficult to repair. Hope this helps. - David

I have a 2003 Ford Escape that is leaking power steering fluid. I replaced the power steering pump and hoses but it is still leaking. It only leaks when the Escape is turned off.


It might be the rack and pinion kit (seals)

I had this problem 2 months ago... replaced the powersteering pump 3 times until I convinced the mechanics to look at the rack and pinion. there they found the leak, especially when I turned the wheel.. They first kept telling me there was air in the lines and it would go away. but that never happened.

Power steering fluid leaks, rack replaced approx a year ago


May have a failure in the replaced rack. I would take it back to the shop that did the work for warranty. If you got a remanufactured rack it was re-built and may have had major problems that were not fixed with the rebuild.
