Yes, they will have o-rings. Also be sure to check tightness before removal, and check for leak behind fittings on the rack from the large 'plug'.

SOURCE: how do i change a rack and pinion bellow on a 98

The bellows is just a dust cover. If fluid is leaking from the bellows, the rod seal is bad. It's usually cheaper to replace the rack than it is to rebuild it.

Will a 2000 lincoln ls rack and pinion fit on a 2004 lincoln ls? Does it matter if it's v6 or v8? I have a 2004 lincoln ls 3.9 liter v8 and need a rack and pinion. Somebody please HELP.


engine size is immaterial when it comes to steering
what matters is body length, mounting positions and methods, tie rod lengths , position of pinion , method f attaching steering shaft
best if you go to a wreckers and view both steering assemblies side by side to check any differences
or you can pull both out and interchange or you can go to a dealer spares and see if the boxes have the same part numbers
or you can ring a steering specialist shop and ask if there is any differences

Ive got a leak in the power steering box near the power steering lines what could it be


most likely it is one of two things. the O-rings on the end of the line has worn and all you have to do is remove the lines from power steering rack and put ne O-rings on. if your car uses a double flare nut style (like a brake line) then it is either the rack leaking or the actual hose leak. if it is the pressure hose you will generally see it spray. not so much on the return line. this requires replacing the part that is faulty

Power steering hard


Hey Kumar,
Does the steering get easier when it gets hot? If it get easier when hot, its the rack and pinion gear. The valve body (actually a teflon composition ring(s) o-rings/valve bore housing are getting worn to the point where they are not controlling the fluid flow when its cold,, when the rack and pinion gets hot, the valve bore expands and "corrects" the clearance which in turn, controls the fluid flow. The valve body bore in the rack and pinion housing is worn where the teflon rings ride against the bore.
This is nothing that can be fixed except by replacing the entire rack and pinion gear. Drain ALL the power steering fluid from the pump also and fill with fresh new fluid.

How to change inner tie rod ends?


if fluid is flowing out the bellows, you need to replace the steering rack assembly. There is no fluid in the area of the inner tie rod. The seal is just before the tie rod.

Steering Gear
The power rack and pinion steering gear is serviced as a power steering short rack (3L547). The front wheel spindle tie rods (3280) and tie rod ends (3A130) are serviced individually. -------------------------------------------------------------------------------------------
  • The power rack and pinion steering gear incorporates quick connect fittings for the power steering pressure hose (3A719) and power steering return hose (3A713) that allow the lines to swivel. This is normal and does not indicate loose fittings.
  • If the fittings leak, check to make sure they are tightened to 14-20 Nm (10-14 lb-ft). Do not overtighten.
  • If the leak is not corrected, replace the fitting seals.

Power steeing fluid leaks


try replacing the o ring or use double o rings between the reservoir and pump, pressure builds from use and the fluid blows out of this o ring even after the vehicle is off. When the dealer replaces the pump they re-use the reservoir and o ring so the problem does not get fixed. The fluid runs down the pump and the lines to the rack, instead of washing the engine and observing where the fluid is leaking from, they replace good parts until they find the problem. Sometimes one o ring isn't enough.

99 Maxima Power steering sticking


I am a Nissan ceritifed Scope Technician with over 10 years experience in a Nissan dealership.

To me, it sounds like your problem is "morning sickness". The problem is there only after the vehicle sits for a period of a few hours (overnight) and then is gone once the vehicle warms up some.

What happens with "morning sickness" is this: there are nylon rings in the pinion section of the steering rack and pinion. Over time, these nylon rings wear grooves into the aluminum housing in which they reside. When the steering rack and pinion is cold, the pressurized power steering fluid can move past these rings causing difficulty in steering or an unsmooth steering condition. Once the fluid warms up some, the nylon rings expand and seal the gap and fluid can't get past anymore and it stays where it's supposed to be, leading to the normal steering you experience the rest of the day.

The only repair for this condition is to replace the power steering rack and pinion. A used one can be a gamble as this could reoccur in a short time. A brand new one is overly expensive. That leaves a good quality aftermarked remanufactured rack and pinion as your best option. And be sure to have the vehicle aligned when that work is completed.

Hope this helps!!!
