Power steering fluid leak in two places on power rod under truck

Toyota Tacoma, 4x4, 1999, has a severe power steering fluid leak on actuator rod under the truck. I have kept refilling it because as it started out as a drip, then progressively worse until full drain. I get the impression there is maybe too much pressure and no relief from the pump, so it is leaking at fittings & gaskets on the hydraulic horizontal power rod that pushes the front wheels to steer.
I am wondering if the whole horizontal rod needs to be replaced; something else specific; or the pump? I do not want to drive it around to places for estimates.

    The lines from the power steering do not leak and the pump seems to provide enough pressure, maybe the system cannot handle the pressure though. I am thinking there is something that regulates or limits the pressure from the pump and if that regulating comes from the pump, Mr Scarry could be right. On the other hand, Mr. Scarry is not specific why he would replace the pump and lines and it could be he owns a auto parts house and his theory is start replacing stuff and eventually you will fix the problem.

    If you did not have a rationale or reason for replacing my power steering pump & hoses, you would not get my business regardless of your time repairing autos. If I specifically requested a reason for the diagnosis and you just ignored my request for a logical reason and said, " because that is what I think ". I'd go elsewhere.

    I could be wrong, but considering the knowledge and attitude demonstrated here, I do not see a professional mechanic making a living for 35 years. I may have worked on my own cars as a teenager; plus spent time pumping gas at a garage 45 years ago; but I would not count it as professional experience and call myself a mechanic. I will leave auto repairs regarding components I do not have experience with to the professionals, but I reserve the right to reject a dubious diagnosis or a mechanic that does not make sense. Just my own rule of thumb that has got me by this long.
    Thanks so much.

It sounds like tour power steering rack and pinion may be leaking this is what you call the actuator rod.

their job is to sell work.however its a good idea to have the brake fluid flushed and the fuel system cleaned.the power steering fluid you don`t have to have flushed,you can if you choose to.you don`t have to have it done at a dealership and it will not void any warranty,if you have extended.

There is power steering fluid dripping from the passenger side boot covering the rod that connects to the wheel. Could a simple replacement of the boot be the fix, or is there a problem with the main unit...


No, the boot only keeps dust out of the inner tie rod joint--it is not intended to hold back fluid. The rack will have to be rebuilt with new seals. Sorry. :o(

My 2001 toyota tacoma is squealing nonstop and i think the powersteering pump is bad is this correct


I'm inclined to believe that your power steering pump is low on fluid or bad.

Squealing can come from any belt slipping or an accessory like the power steering pump being worn out.

Good luck, to you.

Noticed a small leak- not sure if oil or power steering fluid (light brown). Couldn't find source of the leak but appears to be somewhere in between the PS pump and timing belt on passenger side. 2006...


put a colored dye in the systems and a week later check it with a black light go to napa and ask from the dye...it might be air in the power steering pump try turning the wheel a couple of times..

NO POWER STEERING IN 1998 TOYOTA TACOMA AFTER CHANGING POWER STEERING PUMP.


Assuming you have a known GOOD pump that was replaced. Try turning the wheel right then left while keeping an eye on the fluid level in the pump reservoir.
Probably have air in the system.

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.
