    I am thinking you have another problem. The gear box should have bleed itself out within a few minutes of the truck running. You should not have to drive it around to get it to burp. Moving the gear box from lock to lock should have been sufficient.

    The Mechanic told me this would take a while since he did not replace the old with the new gear box for 24 hours

    nope, the system is under high pressure and should work itself out in just a matter of minutes. You should top off the pump and start the truck, turn the wheel from lock to lock and double check the fluid. Start it back up and go lock to lock again and it should be all but bleed out. There really isn't any hiding spots in the system.

  • Hi Info, I appologise for not having given step by step instruction. 1) Start the engine. 2) Check the ATF level in the reserviour 3) Top up and keep checking and topping during following proceedure. 4) With vehicle sationary and engine running, DO NOT drive vehicle, but instead turn the steering wheel to FULL LEFT lock and hold for about four seconds. (Holding full lock longer can overheat the ATFluid and cause damage to the pump) 5) Repeat the same action to the right. 6) Keep repeating action until the effort required to move the steering wheel reduces and becomes 'normal' Regards John

Hi Info, With wheels on ground and NOT propped at all, turn the steering wheel to full left lock, hold it for no more than four seconds and then turn to full right lock. Holding the wheel at full lock for an extended time will overheat the fluid and damage the steering pump and box. Repeat the procedure until the steering becomes light on both left and right turns. Regards John

If you make sure your fluid lvl is topped off and start the truck up, turn the steering wheel all the way to the right and hold it there for a few seconds then go all of the way to the right and hold it there for a few seconds. Repeat this a few times and it should work all of the air out of the system. You will probably need to check the fluid level a few times as when it burps the air out the fluid lvl will naturally drop.

    Power steering fluid is right at max level. It has not moved since gear box was installed. Could he have mixed lines up on the installation?

SOURCE: bleeding the cluch pedal

Open the slave cylinder bleeder and let it gravity feed for 5 minutes or so, then close the bleeder and have someone pump the pedal, release the bleeder to remove trapped air, repeat as needed until all the air is gone and pedal is firm with no play.

Adjust your rear brake shoes. Then rebleed the system. Start at the master cylinder Bleed master first then the wheel furthest away from the master (right rear then left rear then right front then left front. Do that and your pedal should be good.

Just replaced steering gear box an now the


if the correct steering box was installed and you have a shudder afterwards then it sounds like you still have air in the system. to bleed the air out you have to start the car and turn the steering wheel all the way left to the stop and then all the way to the right to the stop. repeat and check the power steering fluid level when the foamy fluid goes away. you don`t say why you changed the box, was it due to a different problem or was it doing the same thing.

I have a 1988 f350 diesel i replaced the clutch master cylinder and the slave cylinder bled the lines and the truck still wont go in gear the throw out arm is moving about 1/2 inch what could be my prob


Ford has special bleeding and blocking instructions for clutch slave. Check manual for proper bleeding requirements. May consider presurre bleeding of master cylinder or use master cyclinder bleeding tubes that fill the resevoir as you bleed the and remove all air in system.

I have 95 jeep grand cherokee i replaced power steering pump and gear box and i still dont have any power steering


Did you bleed the power steering pump after you replaced it. I know its a dumb question, but I have seen it before.Slowly move the steering wheel back and forth from stop to stop. Make sure the fluid is always full or you will reintroduce air into the system.

2003 Ford F350, massive hydrolic pwr steerinfluid leak


What I think you are referring to as the pump is really the steering box because the pump doesn't have an arm connected to it. The pump has 2 hoses and a belt going to it. From what you describe it sounds like you need a pitman shaft seal. The seal is replaceable but you will need a pitman arm puller to get the pitman arm off. If you don't have or can't get a puller don't even bother starting the repair, as you WILL NOT get the pitman arm off without one. When you get the pitman arm off clean out around the shaft and you will see a snap ring. Remove the snap ring. Now make sure the power steering is full of fluid. Start the engine and turn the steering wheel all the way one way or the other and hold it there while increasing the RPM. Doing this will literally "BLOW" the seal out. There will be a couple of spacers and maybe another seal that come out of the hole also. So read the installation instructions that come with the seal kit and it will have a picture of where the components go and in what order they go in. Don't forget the snap ring. When done replaceing the seal you have to center the steering box. From all the way one way turn the steering wheel all the way the other way and count the turns. Now turn back the other way half as many turns and the box is centered. With the tires pointed straight (not turning) the pitman arm should go right on. The pitman arm will go on the pitman shaft in 4 different places. So if you don't center the box and the wheels you might have say one turn to the right before the steering wheel stops and three turns to the left. With all this done fill the power steering with fluid. With the front tires off the ground and the engine NOT running turn the steering wheel all the way from stop to stop 4 or 5 times and then check the fluid again. Fill the fluid and turn wheel from stop to stop another 4 or 5 times. Doing this will "bleed" most of the air out of the system. Now start the engine and turn wheel from stop to stop a few more times to "bleed" any remaining air from system. Turn off the engine and check fluid level. Hope this is helpful.

Toyota steering too light


The only way I know of to bleed a power steering system is to turn the steering wheel from lock to lock (all the way to one side and then turn all the way to the other side) 3 or 4 times. that will bleed all the air out of the system. You might have had a leak for a longer than that you realized and by fixing the hose the power steering works VERY good and you are no long used to how easy it once worked.
