How do you replace a power steering pump on a Cadillac?
The 1956 Cadillac equipped with power steering was quite easy, loosen the bolts on the pump and remove the belt, un bolt the reservoir/pump Assembly and turn it upside down so the oil drains out. Disconnect the lines and reverse process to re instal.
If you would like to know on a different year you will need to provide year, engine, and model Cadillac.
How do you remove the power steering pump on a mini?
Tools and supplies needed:
10, 13mm sockets with ratchet and extension(s)
Medium side-cutters (6" or so) to remove the crimped hose clamp.
Floor jack and pair of jack stands
New hose clamp
Small screwdriver to release the tabs on the power connector
Medium screwdriver to install the new hose clamp
Drain Pan to catch the mineral oil
1L can of Pentosin CHF 11S
Optional: new O-ring for the high pressure line
De-greaser to remove spilled oil
Procedure:
1. Remove the two 13mm nuts that attach the fan bracket to the PS pump bracket
2. Disconnect the fan electrical connector and set the fan assembly aside.
** This would be a good time to check the fan to make sure it spins smoothly and easily.**
3. Remove the two connectors from the PS pump. - The small connector has one retainer that can be released by squeezing the tab toward the connector body. - The large connector has two tabs that need to be released by gently prying them away from the connector body. It is easy to break these tabs.
4. Remove the hose clamp from the hose that goes to the reservoir. Since it is crimped on it can be a PITA to remove. I have successfully at removed these by putting a screwdriver in the crimped area and prying the crimped area apart. YMMV
5. Remove the 13mm bolt that holds the high pressure line to the pump.
6. Position the catch pan to catch the oil that will spill when the hose is removed from the pump. - You may want to have some rags handy to keep the oil off the sub-frame. Clean up will be easier this way.
7. Remove the two hoses.
8. Remove the 13mm nut and the two 13mm bolts that attach the PS pump bracket to the sub-frame - The two bolts are visible (barely) at the rear of the sub-frame in the area of the down-pipe.
9. Drop the pump far enough to remove the wire retainer clip.
10. Remove the pump.
11. Remove the four 10mm nuts that hold the pump to the mounting bracket.
12. Installation is the reverse of removal.
The thing that was the most frustrating was the removal of the low pressure hose. Everything else was pretty straightforward. If you have everything ready to go, it should only take about 1/2 hour or so. Partly depends on how difficult it is to remove the hose clamp.
a bad cv joint. on front wheel drive cars, it may be the CV joint...try a free brake inspection at a chain brake shop, and while they're checking it for free and no obligation, ask the mechanics to take a peek at your CV joints and boots..:) also everyone should have a manual for their vehicle, and a professional shop manual should be available at your local library in the reference section, make copies of the appropriate pages, and good luck:)
What if you put oil in your power Steering fluid?
Power steering fluid is typically hydraulic or transmission oil. Drain the engine and change the filter. Replace the oil in the crankcase with the correct oil and amount. I don't believe it will damage the car but PS oil was not designed for use in a crankcase of an internal combustion engine.
How do you change steering gaiter on citreon saxo?
To change the steering gaiter on a Citroën Saxo, first, lift the front of the car and secure it on stands. Remove the wheel and the retaining clip from the old gaiter, then slide it off the steering rack shaft. Fit the new gaiter in place, ensuring it's properly seated, and secure it with the retaining clip before reassembling the wheel and lowering the car. Always check for any leaks or damage after installation.

How the power steering mechanism works?
Power Steering There are a couple of key components in power steering in addition to the rack-and-pinion or recirculating-ball mechanism.
Pump
The hydraulic power for the steering is provided by a rotary-vane pump (see diagram below). This pump is driven by the car's engine via a belt and pulley. It contains a set of retractable vanes that spin inside an oval chamber.
As the vanes spin, they pull hydraulic fluid from the return line at low pressure and force it into the outlet at high pressure. The amount of flow provided by the pump depends on the car's engine speed. The pump must be designed to provide adequate flow when the engine is idling. As a result, the pump moves much more fluid than necessary when the engine is running at faster speeds.
The pump contains a pressure-relief valve to make sure that the pressure does not get too high, especially at high engine speeds when so much fluid is being pumped.
Rotary Valve
A power-steering system should assist the driver only when he is exerting force on the steering wheel (such as when starting a turn). When the driver is not exerting force (such as when driving in a straight line), the system shouldn't provide any assist. The device that senses the force on the steering wheel is called the rotary valve.
The key to the rotary valve is a torsion bar. The torsion bar is a thin rod of metal that twists when torque is applied to it. The top of the bar is connected to the steering wheel, and the bottom of the bar is connected to the pinion or worm gear (which turns the wheels), so the amount of torque in the torsion bar is equal to the amount of torque the driver is using to turn the wheels. The more torque the driver uses to turn the wheels, the more the bar twists.
The input from the steering shaft forms the inner part of a spool-valve assembly. It also connects to the top end of the torsion bar. The bottom of the torsion bar connects to the outer part of the spool valve. The torsion bar also turns the output of the steering gear, connecting to either the pinion gear or the worm gear depending on which type of steering the car has.
As the bar twists, it rotates the inside of the spool valve relative to the outside. Since the inner part of the spool valve is also connected to the steering shaft (and therefore to the steering wheel), the amount of rotation between the inner and outer parts of the spool valve depends on how much torque the driver applies to the steering wheel.
Animation showing what happens inside the rotary valve when you first start to turn the steering wheel
When the steering wheel is not being turned, both hydraulic lines provide the same amount of pressure to the steering gear. But if the spool valve is turned one way or the other, ports open up to provide high-pressure fluid to the appropriate line.
It turns out that this type of power-steering system is pretty inefficient. Let's take a look at some advances we'll see in coming years that will help improve efficiency.
What type of power steering does a 1999 Ford Taurus take?
Motorcraft MERCON automatic transmission fluid is used as the power steering
fluid ( according to the Owner Guide )
What are the risks of a power steering leak?
Three main risks are associated with power steering leak:
1) Loss of easy steering capability
2) Low amounts of power steering fluid can cause the power steering pump to fail, which is another expensive item
3) Risk of fire with the fluid being dripped on the engine
Rear wheel drive, tie rod ends, pitman arm, gear box itself.
Front wheel drive, tie rod ends or the rack and pinion.
You need to remove the entire power steering pump.
There are two bolts holding it on at the 12 and 6 o'clock position.
Remove these via the holes in the power steering pump pulley.
(no need to remove the pulley)
Push the pump to the side and you then have access to the water pump bolt.
Hope this helps.

Why does your car pull to one side when you take your hands off the steering wheel?
If your car pulls to one side when you release the wheel it could be one of a few different things. Most commonly this means it needs an alignment. There are three different alignment settings...toe, caster, and camber.
Toe is the most easily adjustable and is the most often needed adjustment. It is the measurement from the front of one tire to the front of the opposite side tire, or rear of one to the rear of the other. When you turn your wheel, the motion of the tires is the motion that toe adjustment sets, but it is in relation of one tire to the other and how straight they travel down the road in a parallel relationship to each other. This setting will cause tire wear, but it is a common misconception that it will cause a car to pull. It will not cause a pull. It will however cause your steering wheel to be off center, or crooked.
Camber is the adjustment of the top of your wheel leaning in or out in relation to the bottom of your wheel causing the tire to ride more on the outer edge of the tread, on the inner edge of the tread, or squarely on the center of the tread as the tire was intended. This setting will cause tire wear, will cause a car to pull one way or the other, and in extreme cases of being out of manufacturers specs can cause unstable and erratic handling. Some cars have adjustments from the factory for camber, though an increasing amount of cars require purchase of aftermarket cam bolts or bushings in order for the camber to be adjusted. This is particularly true of a lot of imports like Toyota and Nissan though it varies my make and model.
Caster is the least needed adjustment and is in some cases not adjustable on some makes and models. It is the measurement of the angle of a line drawn through your upper and lower ball joint in relation to the ground. Imagine a line traveling from the top of your tire to the bottom that is straight up and down. If you leaned the top of that line toward the front or the rear of your car, that would be the movement of the caster. The rake angle on a bike is the same thing. Caster adjustment affects the straight line stability of a car and how quickly and easily a car will turn into a corner. Caster does not cause cause tire wear and will not usually cause a pull, except in extreme cases of caster offset between one tire and the other.
Sometimes a manufacturing flaw in a tire will make it cause a pull even when the tire is brand new and with a perfect alignment. This is commonly called a radial pull. To diagnose a radial pull, swap the front tires and drive the car again. If it is a radial pull, the car will now pull on the opposite direction as it did before.
Some other causes are tires already irregularly worn from a bad alignment, worn shocks, or lack of proper rotation. Also, mismatched size tires on each side, uneven tire pressures on each side, and early signs of tire malfunctions such as a broken or separating belt inside of the tire carcass. Broken or separating belts are most commonly accompanied by a shake or vibration and may or may not cause a pull.
Why did your power steering stop working and my battery light come on?
Check your fan/accessory/serpentine belt.
How do you use a puller to install a power steering pump pulley?
The puller will not put it back on. It's made to remove it only.
To reinstall the pulley requires a bolt about 3 inches long, a nut, and flat washer that fits the bolt. There are threads inside the hole on the end of the pump shaft where you insert this bolt. First place the pulley onto the shaft and hold it in place, then install the bolt into the pump shaft. Then hold the bolt head with one wrench, while you tighten the nut and washer against the pulley with another wrench, and it will push the pulley onto the shaft.
Can high water exposure cause power steering to fail on hard turns at slow speeds?
Yes, I've had this happen to myself. Usually resolves itself on it's own.
What part do you need to replace if the steering on a 1985 Jeep CJ7 is really loose?
well first you need to know that it can be more then one item. so a little inspection is in order. have someone, engine running brake on, move the steering wheel back and forth a2 to 3 inches while you look at the steering linkage. areas that are weak are: drag link end (tie rod end that attaches to the pitman arm on the gear box) if it moves side to side and or pops up and down change it.
the frame. yup the frame can be cracked. look close at the gear box mounting brackets. are they moving around? if yes, remove bolts, clean and reinstall with lock tight.
check the frame rails where they attach to front cross member and the bumper bolts. what your looking for is movement. any is bad. if all that is good there is a "slip joint" on the shaft that connects to the gear box. see if there is any play there. (a trick, if play is present remove clip holding rubber cover in place, pull joint apart and you will notice 2 small "slip bushings" very carefully remove the spring clip and turn the slip bushings (square bushings) 180 degrees and reinstall with clean grease.
and last-- take your jeep to a good alignment shop and have the suspension and steering inspected.
