First of all there is no pitman arm on a 2004 new body envoy, only on the jimmy style. There are two orients on the rack and pinion, not sure if you can buy them separately. An 8mm head bolt holds both lines into the rack and pinion. Remove the bolt pry the lines off carefully. On the rack and pinion you will see two orings

SOURCE: The power steering gear broke off of the frame in

Unfortunatly The Steering Gear Box MUST Be REPLACED. Ther is Not an Easy Way to Repair it.
if the Case is broke you will Have to Pay The CORE Charge Also. THERE ARE 4 BOLTS 3 Through the Frame to The Box 1 for the Steering Shaft ,AND 2 P/S PUMP LINES TO IT AND THE PITMAN ARM NUT You Will need A Pitman Arm PULLER for the Pitman Arm.

My power steering pump went out and I replaced it now its leaking somewhere else and it not the hose


Hello Jen, there are only a few places a power steering system can leak.
1, The pump itself
2. The feed hose
3. The return hose
4 The fluid reservoir
5. The reservoir hose(s)
6. The steering gear itself.
Now, its a simple job of elimination.
Do you have rack and pinion steering...there are several places a gear can leak also.
Please do some investigation. reply to me and we'll go from there.
I am considered a rack and pinion system expert.

My power steering fluid is leaking, i fill it up and it all leaks out does this mean the the hose is busted or the power steering gear is no good, yet when i fill it back up with power steering fluid it...


The most common cause is a leak in the power steering line. With someone sitting in the car,(and the car running) watch the power steering line and ask them to turn the wheel in both directions. A leak in the power steering line will spurt fluid during this exercise whereas a leak in the power steering unit itself would tend to ooze fluid due to less pressure.

Can low steering fluid cause mechanical problems


Problems associated with low power steering fluid…

Hard Vehicle Steering
A low power steering fluid level can often times cause a vehicle's steering to become hard and labored. Adequate amounts of power steering fluid are necessary to enable a vehicle's power steering system to function and operate at optimum levels. A lack of power steering fluid in a vehicle's power steering system reduces the amount of hydraulic fluid pressure necessary to efficiently operating the various parts of the entire power steering system. Power steering fluid supplies the fluid force needed to operate the power steering gears and to enable power steering gearbox operation. Low power steering fluid levels reduce this hydraulic pressure, which commonly results in hard vehicle steering.

Pump Noise
It is very common for a low power steering fluid level to cause significant power steering pump noise. An adequate amount of power steering fluid is required to ensure the proper function and longevity of a power steering pump unit, which is a belt-driven pump responsible for housing and circulating power steering pump fluid. A low level of power steering fluid results in increased power steering pump friction, heat, and wear, all of which can significantly reduce the operational life of the power steering pump while at the same time cause excessive power steering pump noise.

Fluid Boiling
Many times a low power steering fluid level can result in excessive heating of power steering fluid, a condition that can seriously degrade the fluid and cause it to boil. A low power steering fluid level results in less available fluid to both lubricate and cool a power steering pump unit. A lack of power steering pump lubrication and cooling leads to excessive heat being generated within the power steering pump unit itself, a condition that translates into the available level of power steering fluid becoming super-heated and degraded. When this happens it is common for the power steering fluid to boil and lose all of its lubricating and heat-reducing capabilities.

Gearbox Wear
The power steering gearbox is a set of gears within a vehicle's power steering system designed to facilitate movement of a vehicle's front wheels. The power steering gearbox is connected to the power steering pump by hydraulic fluid lines that deliver a constant supply of power steering fluid to the power steering gearbox. A low power steering fluid level, especially a chronic and severe low power steering fluid level, can lead to increased friction and wear within the power steering gearbox assembly, a condition that can significantly shorten the operational life of the power steering gearbox and negatively affect its operation

Problems getting my Ford to turn corners.


A simple thing to check is to make sure your power steering belt didn't come off, or check to see if you have any power steering fluid in the reservoir, as it could have a leak too. If you don't have power steering, there isn't much that can fail quickly, except maybe the steering gearbox? If you don't see anything obvious, have a mechanic give it a look over

Power steering leak on a 1988 full size bronco


The gear box is a common problem on this model. That would be the place I would start. A cheap, temporary fix is to go to your local parts store and ask for Lucas Power Steering Stop-Leak. It will buy you some time.
