    HEY WOULD BE NICE TO SEE YOU DO A TROUBLE SHOOT ON A HYDROBOOST SYSTEM, MY 05 DENALI HAS IT, STEERING WAS SOMETIMES HARD TO TURN RIGHT AT IDLE, PEOPLE I TALKED TO SUGGESTED STEERING BOX, I FLUSHED THE SYSTEM THEN INSTALLED THE NEW BOX, SEEMED BETTER BUT EVENTUALLY SAME PROBLEM, TALKING TO OTHERS THEY SID PULL MASTERCYLINDER AND IF ANY LEAKAGE FROM HYDROBOOST UNIT GO AHEAD AND REPLACE, YOU GUESSED IT IT HAD SMALL AMOUNT OF HYDRAULIC FLUID, REPLACED IT AND NOW NO POWER STEERING, GUESS I HAVE TO GET A POWER STEERING PRESSURE GAUGE KIT. PROBALY A BAD REBUILT HYDROBOOST UNIT?

  4. I have a 2008 Chevrolet Captiva 2L Diesel. The issue I experience is loss of power steering after driving the car over about 3200rpm for more than 3 or 5 seconds. Not that much of an issue but the car becomes very hard to turn when going under 20kmh. It requires a few hard jerks right and left and I can feel the power steering popping back again. So this seems like a stuck valve piston to me? I guess when the revs go up the fluid heats up and the piston gets stuck? Will replacement of the pump help?

  5. I have a 95 Toyota 4runner 3.0 v6.. power steering pump keep going dry it needs to have fluid put in every 100 miles.About a month ago i replaced a hose that was busted. Consistently replace the power steering fluid every 100 miles. Realized I am suppose to put ATF instead of PSF in the power steering pump. Did I mess the pump/system up when I used incorrect fluids? I did a flush and have been running manufacturer spec fluid for a week, but no change still have to replace fluid every 100 miles. Tried multiple brands of PSF-leak stop, no luck.

  6. My '01 Tahoe had a pump failure about a year ago. The shaft sheared and a friend in VA (mechanic) replaced it. A couple of days ago I was on my way home from dinner and the pump (or something) failed. It will not turn in either direction. I pulled the belt and pulled on the pulley to see if the shaft had snapped. It appears the shaft is intact. I'm stumped and stuck in the driveway. :(

  7. Excellent

  8. I have a question, i had a leak in my 2000 Lexus SC 400 the reservoir hose was cracked so took it to a shop replaced it, flushed the power steering as well.. Car before this was absolutely fine.. Turning was smooth, quiet everything.. Now after they did the flush and replaced the hose, my steering is so hard to turn and makes a loud grinding metal noise, they tried telling me it's air or a bad pump.. But it wasn't doing that when i took my car in.. Just right after they worked on it.. Any ideas?

  9. GUYS,
    It seems if you were preparing to replace your PS pump, it would be best practices to first change the fluid. That way when your new pump first operated it would be in new fluid.

  10. These guys are definitely not "parts changers" . they know their stuff!!

  11. HaHa,,, he's obviously an instructor at a college…

  12. I have an 01 Impala and when I start the car the power steering work for 15 minutes and then it's hard for the rest of the day

  13. i really learn a lot from your videos, John I hope Tech Garage continues, it is my favorite show on Velocity.

    Good video. Question: I have an RV, with a Hydroboost system. The brake system seems normal, except for " chatter " on occasion from the Hydroboost unit. Could a defective PS pump ( to high or to low pressure ) case this? The pump and Hydroboost unit are both quiet normally, except for chatter upon brake application. Also, both low pressure return lines go back to a " T ", before returning to the pump.  The low pressure line from the steering box gets the straight shot through the " T ", while the Hydroboost low pressure line comes in the side of the " T ". Can this type of " T " cause a problem with the low pressure lines? Should there be a more " merging " type of fitting here for good return flow? The vehicle is a 1979 King Highway, on a Dodge chassis. It has 91,000 miles on it. Any help is appreciated. Thanks…

  15. I have knocking on steering from center when stationary. ive been told the steering rack has failed. They have then told me i have to replace the steering rack and the whole power steering. they have Quoted me £1300 in parts alone, i suspect there fobbing me off what do you think i need ?

  16. i have a 2006 Nissan Altima 2.5 ,  I decided to take out the old dirty fluid in reservoir . used a turkey baster,  siphon pump . everything that I could see looked good ,res screen, hoses etc , anyhow I did something else momentarily and mistakenly started up the car and turned steering wheel left to right, stop to stop , for approx10 seconds ,it was whining etc then I realized I  FORGOT TO PUT NEW FLUID BACK IN !! I know it was one of those boneheaded mistakes !  thankfully  the whining went away , and the steering seems normal . if the pump were to burn out or fail would it have done it right then and there?

    This video is amazing.

  18. One thing I found out what to look for on the Chevy LSX engine in a Holden Commodore (Chevy Camaro setup) and Buick V6 engine, where the reservoir is mounted above the pump and is supplied with fluid via a 5/8 inch suction hose is that as the hose ages the rubber goes hard and the clamps also become loose thus causing air to be sucked into the pump causing aeration and fluid leakage from the hose.
    This is listed in the AC Delco power steering catalogue as a known fault in the VS – VY Commodores (1995 – 1997 for sedans & up until the year 2000 for utilities with the VS Commodores) ,except all the Commodores till 2000 where they were fitted with the locally produced 5 litre V8 engine where the pump was internally mounted inside the reservoir,it is recommended to replace all old hoses & clamps when fitting a new pump with the exception for me is that I only had to free up the flow control valve which became stuck in the fully open position.
    I still had a bit of trouble with the steering going a bit hard intermittently and air bubbles were still coming out of the system so obviously the hose was the culprit though it could've been a number of possibilities such as a loose flare nut on the pump or rack but it turns out this wasn't the case.

  19. at what RPM power steering pump work in small hatch back car for peak power
