my 2004 toyota tundra with 215k miles on it lost its power steering and was making moaning noises, lets swap out the pump and open the old one up to see what happened.

Youre truck didnt fail. Thats a part that eventually goes bad on all vehicles. Its really not that big of deal
Hey I've got a 2004 tundra I've got this squeak that gets worse with higher RPMs I've changed both the idler pulleys and that didn't take care of it. So this morning it's really noisy so it was just idling not making much noise at all and I put a little WD-40 on that front bolt where the pulley is and it stopped immediately I'm wondering if that's my problem. I guess that pulley is built into the power steering pump so there's no changing it or having a bearing go bad correct It's probably the bearing that's inside there that's starting to make a little noise, what do you think?
All the rubber o-rings the copper rings they're all different sizes cuz of china made junk. Again I think they're probably effing with our minds, I've had a ton of problems with the o-rings and copper rings and seals and stuff it's always different the size. I'm having a problem now with an aftermarket radiator cap. I've tried Delco ones I've tried out aftermarket they don't quite seal. It's horrible anymore these parts just horrible and they want a fortune for him because China is raised their prices because of Trump's tariffs. Your son of a bitches and making them cheaper and cheaper in the wrong size like I said
I just went through all of this with my Toyota pick up, 310k miles. My pump was getting noisy, I think actually because the screen in the reservoir was near completely blocked with 30+ years of debris. Replaced pump with a reman and disassembled old, original Denso pump and could find no obvious damage and little wear. Very impressive. It's quit possible that what caused the noise chirping was in fact not only some air but poor re-circulation through the near plugged reservoir screen. So, $225 later I have my PS back with new hoses and pump.
Excellent video, helped a lot, thanks
Thank you so much, I did it, I fix my truck with your video
Its crazy what happened to you exactly happened to me also! Now i have to do my other tundra PS.
You get the front end up and without starting the motor, turn the the steering wheel all the way to the right and left several times keeping adding the fluid to desire level.
Thank you, exactly what I was looking for, mine had the main seal damage by a broken serpentine belt, leaking slowly, until I figured it out. I was wondering how to remove the shaft, pulley puller don't work!! Thanks again
One of your best videos. I like the switch up.
maybe the pump got hot from redline, and the bearing on the pulley was tight, and the oil was too old and lost some viscosity when it got hot
I wish you would have cleaned it up and then put it back together and test it.
My beater car pump was a bit noisy and I added some moly crap to it and it quieted down as months passed.
Downside is the fluid now looks like its full of metal shavings.
Thanks for the video. I have 2000 Tundra and everything looked the same under the hood so the video helped me decide to tackle the job myself. It helped big time and made it easier to get it done. Actually the alternator was starting to fail and knew that I had to remove steering pump to get to it from top cuz I didn't want to get to it from under the truck. So thanks very much for the info, I accomplished 2 tasks because of this video.
Hi Mustie, Do you still have this truck, how is the frame holding up
Same thing happened to me so now we know drifting in the snow kills power steering pumps. It was cold and changing the pump on a awd 99 caravan isn't so easy and I don't have a garage other then my work so i had to find some time to change it so for the two weeks before I did I drained the system and filled it up with probably 90% lucus transmission stop slip and well it took awhile and until it was as temp for 10-15 minutes it would come back to life once the fluid thinned up enough for the poor old pump to pump it it was the original pump with 260k miles on it
I believe there would have to be s restriction.
To allow air.. then the galling starts.
Look for a filter or screen
Cool fix! Any time you need to reuse a copper seal washer, heat it to just cherry red with a propane torch and allow it to air cool. This anneals the metal and makes it soft again. When copper is worked or compressed, it "work hardens" and becomes stiffer, making a good seal sometimes very difficult when it's reused. Annealing the metal allows the copper to re-form against the sealing surfaces just like a new one will.
I know there are rebuild kits for these but wonder if it's worth doing? A few years ago before getting my Tundra I rebuilt the PS pump in my older yota pickup at 170k miles and it was a bit of a hassle and I'm very mechanically inclined. These actually look simpler, and what may be missing or worn is a rubber 0-ring seal or two that go inside. One of mine had almost completely disintegrated and sometimes there's nothing left of them. I carefully rebuilt mine, even flushed the system really good beforehand but after reinstall it didn't feel like it was as good as it should be. It worked, and no more squeals, but just didn't feel like I think it should. Maybe the metal impeller vanes just wear too much and are under tolerance, even though I checked specs with a micrometer.
Hello,
Where did you buy the pump?
Thanks
Have a 04 4runne with 240k. My pump is leaking but still works. Ordered a rebuild kit. This video just help my figure out how it comes apart. 🙂
I guess I got lucky. In a tad over 400,000 on my 03 4.7L tundra. It's not winning but it's leaking beyond belief. I want to rebuild it with OEM toyota seal and bearing kit but I can't locate one. I don't want to drop $350+ on a new one
Thanks for taking it apart and showing us! You The Man!
Thanks for doing this video. Mine is a 2006 I purchased in 2006. 200k and doing this job tomorrow.
Good video! Thank you for the depth and friendly narration 🙂
When’s it’s cold outside Anyone ever get loud belt squeak or almost like a pulley doesn’t spin and stops the serpentine for a few seconds on start up? Only when cold on startup for a few seconds runs fine besides that’s 4th gen 4Runner v8
