Do i need a power steering flush and an alignment when they replace the rack for a power steering rack leak?

Um... the video didn't demonstrate anything, only showed the steering wheel and the key.

If the engine is running, the tires aren't jammed against solid objects, there's no noise from the pump, the belt is tight, the power steering reservoir is full of fluid, and the steering wheel is still very hard to turn... then I suspect that the power steering pump has simply worn out badly and needs to be replaced.

Lets use common sense here

It leaks,you stop using the car & repair the leak

Most likely the steering rack is worn & needs to be replaced

That's what happens when you don't flush the fluid every
3 years or it leaks & runs low

Part blockage in oil lines or bad steering rack. Flush system and check. If no improvement repair/replace rack.

hope this one help http://www.popularmechanics.com/cars/how-to/maintenance/3322636
This instructable is designed into four main parts. Here's the outline:

1) Gather the materials
-- Instructable step 1 - This includes tools, a new pump, fluids, etc.
2) Remove the leaking pump
-- Instructable step 2 - Drain the Power Steering system
-- Instructable step 3 - Remove accessories from Power Steering system
-- Instructable step 4 - Remove the pulley and bolts
-- Instructable step 5 - Remove power steering pump
3) Install the new pump
-- Instructable step 6 - Place the new power steering pump
-- Instructable step 7 - Press on the power steering pump pulley
-- Instructable step 8 - Align the pulley and attach the belts
-- Instructable step 9 - Flush and fill the power steering system
4) Cleanup
-- Instructable step 10 - Cleanup

You'll need some tools to complete this task. Before you start, gather the necessary equipment -- you will not be able to use the car once you start the replacement! It is always a good idea to have a friend on call, or a second car available.

Equipment list:

• Power Steering pump (to replace defective pump)
• Two (2) quarts power steering fluid or appropriate ATF (to flush and fill). More than 2 quarts if flushing the rack is desired.
• Power Steering Pulley Puller set (to remove and attach the pulley). Some auto parts stores will loan the tool sets.
• Socket set.
• Open end wrench set (for use with puller set).
• Leverage pipe or extension bar (in case the pulley is hardened on the spindle).
• Drain pan (to drain & flush power steering system).
• Wheel bearing grease for sliding pulley on the pump hub.
• 2' wood 1x2 for assistance with aligning the pulleys. Any straight tool will work fine -- a level, metal rod, wood, whatever.

To change the rack and pinion on your Monte Carlo you must first jack, or lift the car up off the ground, and remove the front wheels and tires.remove any plastic shrouds that block you from the bottom of the car.then you will need a Tie rod separator they make different types.You remove the tie rods from the front spindles.Trying not to damage the rubber on the tie rod ends that is what holds the grease inside for lubrication.then, if you look at the power steering hoses. these should come directly from the pump.loosen both the pressure, and the return hoses and remove from the rack. you will need a fairly large oil drain pan to catch any leaks that may happen. If you look where the steering shaft comes from the passenger compartment down to the rack. it must be removed from the rack, Note; center the steering wheel before removal of the new rack.Then the rack should have some mounting fasteners holding it to the chassis. when you replace this part,The new rack does not come with the tie rod ends that you had removed earlier from the outer ends of this part at the wheels. the old ones will need to be removed from the old rack and reinstalled back on the new rack.NOTE; to get these tie rod ends fairly close back to the same location,after you break them loose, you count the number of turns to remove these from the old rack. this has to be done to be able to get the front wheels back in close alignment and remember this count. because you replace these on the new rack and the count that you had coming off is the number of turns to put these back on the new rack. and tighten these down good.This rack may have to come out the sideways, or it may have to be got out by removing something that may be blocking removal. just look real close and see if there is a clear area it can come out.When you Install this new rack and pinion you mount the rack and install the hoses refill your power steering pump with fresh fluid. and check for any leaks. and before you install the hoses replace the o rings if there is any to make sure you have a good seal at your connections. then hook up your steering shaft to the new rack and check to see if you are still in alignment( steering wheel)after you hook up the tie rod ends and the new rack is mounted securely. double check your fluid level in the pump.you should get all the air out of the system, by cranking the engine and turn the steering wheel right and left all the way to the lock. ( or the stop) until you dont hear anymore noise from the system. it may take driving a little while before the noise is gone completely . Keep checking your pump fluid level while you are bleeding the air out of the system. and also keep your eyes on the areas where the hoses that you removed and replaced for any leaks that may be a problem.also when you install any fluid lines,always start them with care. make sure not to cross thread these lines. start them with your fingers first. then you should have the car alignment checked at a alignment shop, or a tire store. this is to make sure you have no alignment issues. and for a few days keep your fluid level checked.

Replace the rack n pinion. Make sure you back flush the lines because there is a good possibility of metal working its way back too the pump. You will also need to do an alignment after the rack is replaced. If you are mechanically inclined you should be able to do this with little problems. Although getting the car above head is ideal. You might find a reputable place and have them give you a quote on replacement. If you do replace the rack yourself, make sure you set the toe about 1/8" in until you can get it into the shop for a thrust alignment. Good luck.

bad steering problems,,your steering rack most likely,but,have you recently been stuck in ditch? when wheels are straight, look at front of car when parked. do wheels look funny? one going one way, and the other going the other? may be alignment. is it leaking any fluid on either side of the front of the car? drivers side? passenger side? if it's not out of alignment,,,wheels out of alignment,,the steering rack is the problem. it may be faulty. if not leaking fluid,it may still be bad. first i would make a visual test look under the vehicle while someone turned the steering wheel to right and left while car is in park,emergency brake on!! look at the steering arms while they turn the steering wheel from right to left. no fluid leaks? any resistance in turning the wheel? any leaks,if so,go to leak and repair with steering line replacement.no leaks? suspect a bad steering rack. hope this helps and thank you for choosing fixya.com i love to volunteer

part #89020661 gm pwr strg fluid,check pwr strg system for leaks and replace those parts first.hope this helps.

Most likely the problem is the steering rack, it is a very easy repair, but you will need to have the front end aligned after you are done installing the rack assembly, make sure all the old fluid is flushed from the system or the new rack will fail from debris left over from the old failed rack

This is definitely a power steering problem. I had this same problem about a year ago. I had to get my Power Steering Rack replaced, this fixed the noise and problem. You can add power steering fluid as a temporary fix, but your problem will not permanently go away. You are probably leaking fluid out of your steering rack.

The sound that you are hearing probably happens more often when you are acclerating around a turn, right?? Does it sound like a little foreign car in reverse?? Also, the wheel may be a little stiff when first starting out.
