At issue is wear. If the seals leak, there is typically bushing wear that allows the shaft to have excessive side play. You could change the seals, but it will start leaking again, soon. Get a rebuilt box and you will be much happier, longer.

How to install a pitman arm on a 1984 chevy 4x4 blazer


It's an easy but physically demanding if you do not have a pneumatic set of tools. The specialty tools you will first have to get your hands on are a Tie Rod remover. otherwise know as a (pickle fork). There are two sizes of these large for ball joint removal and small for Tie rod removal. Looks like a big 2 pronged fork. The next Tool is a Pitman arm remover. Usually you can rent or barrow them from your local auto parts store. Drive your blazer up on to a set of repair ramps. Block the rear tires.The bolt to the center link from the pitman arm has a crown nut on it with a cotter pin going threw it. Remove the cotter pin.and remove the crown nut. Then with the Pickle fork and a 5 lb. sledge hammer. place the pickle fork between the center link and the pitman arm bolt. Give the end of the Pickle fork as many good blows on the other end as it takes for the center link to release from the pitman arm. Once that is done take a break I know you'll need it. Next is the Pitman arm to the steering gear shaft. Hope you can get your hands on a good breaker bar or an impact wrench and a socket large enough for the steering gear shaft nut. Remove the nut. Then place the Pitman arm removal tool between the pitman arm and the steering gear housing. Start tightening the threaded rod the remover up against the shaft. It is hard as hell to remove because pitman arms rarely go bad. It's usually the center link that fails.It will take a lot of strength to remove and you may want to use a little penetrating lube on it. Once you get that off you may want to replace the steering gear shaft seal as well. Otherwise just reverse the removal steps. The shaft is notched and so is the pitman are make sure they line up. then Torque to spec.s If you plan on keeping the blazer get a repair manual from your auto parts store. It will help you put a great deal.

How do you replace pitman arm shaft seals?


Remove the pitman arm, remove the lock ring in the steering sector, and then remove the washer and seal or seals (some units have 2 seals). Sometimes the old seals and washers are tough to get out. The new seals etc. usually go in pretty easy. It's a messy job because fluid runs all over once the seal is out.

In order to remove the P/S Gear Pitman Shaft Lower Seal where the Pitman arm is attached on a 1995 chevy G10 van , can the seal be removed from the outside by just removing the Pitman arm or does the gear...


Once you have the arm removed (use a puller made for that) You need to remove the c clip retainer. Many times you can loosely install the arm, put it back on the ground and with a catch pan under it, just quickly turn the wheel and pressure will drive the seals out. If that does not work, you can use long self tapping screws and put one into each side of the seal and pull it free. Most i've seen always have two seals separated by a steel flat washer. To re-install, you need to carefully drive the seal back in using a piece of pipe or anything that fits and does not damage it. I have special tools I made long ago to do that but the trick is to be careful not to get the seal too far in on any one side and to not damage it in any way. Likely someone makes an install tool. Make note of the order of the seals as you remove them and make a reference mark on the arm and shaft so you can get back together the same way it was.

Replace bottom o ring on power steering box on a 1979 trans am


I'm guessing that you mean the oil seal at the pitman arm, where the stering connects, since this is the seal that usually goes bad. You need a pitman arm puller to remove the pitman arm. It is a specialized tool and not easily substituted for so try to borrow or rent one. With the pitman arm off there is a snap ring that has to come out. Once that's out get an empty drain pan and put it under the box. Start the engine and turn the wheel hard to the right, all the way. This should blow the seals out. With the seals out shut it off. In your pan should be a dust shield, a washer and the oil seal.
If you have to go in there with a pick BE CAREFUL not to scratch the steering shaft. If you scratch it, go buy a used steering box.
BEFORE you put the new seal in, get some emery cloth and clean up the rust and grime from the steering shaft and the inside of the box up to the snap ring. Make sure both are smooth and clean. This is critical because the seal can be torn or scratched or bent and won't seal properly and you can do it again. Tap the new seal in with a big socket that is the same size until it seats in the box, replace the washer and dust shield and snap ring. Turn the wheel until the pitman arm slides back on. It will only go on in one position. Tighten it to 185 ft-lbs if you have a torque wrench. If not use a strong arm and tighten until you can't turn it any more. Fill the steering pump and try it out. This should work.
Keep in mind that over time, believe it or not, that rubber ring will wear grooves in the steering shaft and you may have to change it anyway if it starts leaking again in the future. Hope this helps.

How to replave steering gear box pitman seal on a '94 grand marquis or a link to online repair diagrams


The easiest way is also the messiest.
Remove pit-man arm nut,Mark the pit-man arm and shaft with a colored marker,to assure you reinstall the arm in the correct position.use a pit-man arm puller to remove pi-man arm.When you get off the shaft,swing it out of your way,leaving the other end connected.Looking up in the steering box you will see a snap ring that you need to remove.When you get it out of there,reinstall the pit-man arm and nut to the correct position but don't tighten completely.Now refill the power steering box with fluid and put the cap back on the steering box.Put a pan under the pitman arm to catch the fluid.Start the engine and turn the steering in one direction as sharp as it will go,you'll here it in a bind but hold it tight,Then turn the steering wheel the complete opposite direction and turn it tight.This will use the power steering to blow the seals out!
Shut engine off,look under car and your seals will be pushed out but held in place by the pitman arm you reinstalled.Now you can remove the arm and REMEMBER how they came out,just incase there is no picture instruction with your new seal kit.

I have a 1994 chevy k1500 4x4 and need to change pitman arm


Take the bolts out that attach the steering box to the frame and pivot the box so you can fit the puller on.
Leave the steering shaft and power steering hoses attached.
Mark the new pitman arm and old one in the same place and mark the pitman shaft to keep the same position of the new pit man arm on the old shaft as the old pitman arm.

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.

Steering box leaking


take big nut off that holds pitman arm to it ,use pitman arm puller to pull off pitman arm. I would get a rebuilt unit ,my luck is that the shaft is so foofed that the new seal wont seal it either. also that shaft that connects to the pitman arm probably moves side toside, so the bushings inside are shot. remember this thing is OLD
