    I also have a Sienna 2004 with the same power steering problem. It goes through some stiffness points as I turn the steering wheel. I checked the power steering fluid and it was missing a little bit. After adding some to the appropriate level, nothing changed. No evidence of any leaks anywhere either. I still have the same problem though. Not sure if I should go to Toyota or some other garage, like a Canadian Tire to have them look at this. When driving, the steering does not go back to the straight position after turning. This takes you off guard as you suddenly need to re-straighten your wheels. I find it dangerous to drive the van. Any ideas what the problem can be?

    Steering was stiff and sticking on turns, took it in to the dealer and they charged me $900.00 to replace the power steering pump. A year later almost to the day I experienced the same problem and this time the dealership is telling me the yolk and intermediate shaft now have to be replaced at a cost of $1900.00.  I have called BS and have told the dealer that they can have the car back.

    I have been having the same problem for several months now and have brought the car in several time. Power steering flush, power steering pump replacement and a new steering rack and the problem is still not gone. Toyota tells me its normal because it's worse when it's cold. BS...it never did it before this winter, why now? I'm not sure what else to do.

  • cmb3443 May 11, 2009

    My 2004 Siena is exhibiting similar steering symptoms. The power assist varies with speed - feels like it comes in and out but is getting worse. The (new) belt squeels for a few seconds when the car is 1st started - no squeel after that.

  • Ray Crawford Jan 17, 2013

    Does anyone know of a video or site that shows the replacement of this Steering Column Intermediate Shaft? The repair is necessary on my van and I'd rather pay the $200 for the part than the $900 for part and replacement. Thanks!

Most likely the problem is the lower steering knuckle. This is the one outside of the firewall, under the vehicle and it hooks up to the power steering assist cylinder. In my opinion the knuckle has to work at an unreasonably steep angle and this compounds the problem. The knuckle (especially in salt areas starts to corrode and becomes hard to turn. Toyota says the water gets into the bearing and they beings to rust the bearing and turning the whell starts to feel stiff. I have this problem and I sprayed liberal amounts of a rust inhibitor that a local place uses to rust proof cars (They sell small spray bottles of it for $5). They are called OIL TECH in Barrie, Ontario and make up their own formula. The formula has addatives that breaks the surface tension on the oil treatment and gets it into the tiny cracks and crevices on your vehicle. I sprayed this all over the knuckle, turned it back and forth a couple of times and continued spraying. I let it sit for an hour and went for a test drive -- problem solved. You could actually see the rust on the exposed parts of the knuckle. I probably will have to do this once every month of two but what the heck. It is a lot cheaper than having to replace the steering shaft ($1000+???) Probably other types of rust proofing or lubricating oils will work. I long for the old days of grease fittings and you never had to replace ball joints and tie rod ends etc.

Norman 783, Thank you, thank you, thank you!!!! I had the same problem with my Toyota sienna that when you try and turn the steering wheel it is stiff,,, etc etc. And your solution about the STEERING KNUCKLE was EXACTLY what was the problem!! You saved My wife and I an enourmous amount of time and money! Many thanks for your tip, I had no rust but, since the Knuckle is essentially exposed to the elements it had gotten some white stuff,,, corrosion/salt etc. like you said and I just sprayed it with carb cleaner(its all I had)and had someone turn the wheel back and forth and Immediately they said it became free and easy to turn!!! I had already replaced the belts, which is not really such and easy task and when that did not work,, I could only think the worst, pump, armature,,,whatever it may be, it was gonna cost a lot!! anyways in a few months if I gotta do it again,, no problem,,,, much easier than shelling out a couple of thousands of dollars. I am laid off and this made my day,

Shortly after posting on April 16, 2009 I brought my Sienna in again and insisted it be fixed before being returned. I mentioned the steering intermediate shaft which I had seen other posts about on the internet. They discounted this because there was no associated noise. As it turned out this was, in fact, the problem. They noted significant corrosion and replaced it. It has been perfect ever since...finally. The link below describes this:

I just spent $1100 to replace the rack and tie rods, plus some other corroded parts. As I left the service station, I still had the same issue! for a few months, I had been losing power steering fluid, and felt like I was turning on a flat tire when at low speed... so thought replacing the rack would be the answer- the dealer, a complete rip off for service, did tell me that they have replaced the knuckle on several 2004-06 siennas.
When I brought my car back to the service station, they had one of the guys test drive it, he called a foreign auto specialist and immediately, that guy said Steering Knuckle!

Could have saved me over $1K! I wish I had seen this first!

By the way, the NHTSA did some sort of investigation, but since most folks go to private shops rather than get molested at the dealer, there was not enough data for them to warrant a recall or further investigation. Only about 1300 people had the EXACT same complaint on their website (http://www-odi.nhtsa.dot.gov/complaints/results.cfm) but will not do anything because we are not on TV in a high speed televised crash!

    Luckly my van is still under warantee. I had same problem- they 1st repaird a leak, still did not fix, then they replaced the power steering pump, still did not fix it. I then printed from here and above and took it to the dealer. I finally took video of me driving and let the dealer see that and he read all the above info. I was the steering knuckle- The dealership is taking the steps to report to ntsb and get some action on it. He said most peoples cars are probably not under warantee and that is why it is not being reported. Also he said smaller fix it places do not have to necessarily report problems like this to the ntsb.

After I saw you post I had already been to the dealer twice. First visit they found nothing. Second they blamed it on an after market fanbelt but still charged me $70 to tighten. I could not even pull out of the parking lot with out it binding up. Went back into the dealer the blamed it on age and again on the after market belt. I googled the problem, you solution as well as NHSTA webbsite and brought that into the dealer they then believed me and replaced the Intermediate Steering Shaft part number 45220-08042. The part cost $254.02. I do have the extended warranty, when they call for my opinion I will try for a refund on the fan belt adjustment.

Thank you Norman 783...for the great tip on spraying Liquid Wrench on the steering U-Joint (Knuckle). I did that on my 2005 Sienna Van last night and it loosened up the steering stiffness after an hour. I didn't jack up or drive onto a ramp, to get under the front, to access the u-joint. I sprayed LW with the can nozzle tube attached. Used a flashlight to see where the u-joint was and sprayed lots of LW at the u-joint.

Being that the U-Joint is exposed to the weather elements - I recommend that you get a can of White Lithium Grease and spray all over the U-Joint. Or use Hi-Temp Grease for wheel/drive axle ball bearing and apply in the area where you see rusting. This will protect and repel water. Spending less than $5 for a can of Lithium Grease will SAVE you at least $500+ in repairs.

Thanks again Norman 783 for the money saving tip on the Stiff Steering problem.

If anyone needs help in fixing their van's power sliding door problem - just post a question. I replaced a tiny motor ($5) inside the door latch motor assembly and saved myself $1000+ from the Stealership (Dealership).

Very hard to turn steering wheel


Um... the video didn't demonstrate anything, only showed the steering wheel and the key.

If the engine is running, the tires aren't jammed against solid objects, there's no noise from the pump, the belt is tight, the power steering reservoir is full of fluid, and the steering wheel is still very hard to turn... then I suspect that the power steering pump has simply worn out badly and needs to be replaced.

94 Camry steering hard to turn like it has no power steering. It has the rack replaced and steering knuckle replaced


Does the power steering have fluid in it. Is the belt on the pump. With it running take the cap off of the pump and see if fluid is moving around. If u feel the steering knucle is to tight u can also take the tie rod off and see if it turns free. Also go back to who fixed it and say its not right, Make it right. Most garages give 12 month or 12.000 mile warranty.

Lift the hood and have the engine idling and in park (or neutral). Have a friend turn the steering from lock to lock and check whether the power steering pulley is complaining or the belt is slipping on it. With the engine off check the belt tension - locate the longest run between pulleys and you should be able to twist the belt a quarter turn only with your fingers. If the belt is slack replace it. If it is the actual pulley complaining it is possible that the bearing is failing. It might be expedient, given the age of the vehicle and the cost of labour, to consider replacing the power steering pump entirley rather than just the pulley bearing.

When i turn or when im driving my steering feels different like its heavy. there s also a drip from one of the hoses. the steering isnt real hard to move but when i go to turn its alittle stiff


You could have a problem with your power steering, but some simple things to check is to first see if your power steering pump reservoir is full of fluid. If it is low or empty, your steering will suffer, and worse would be the power steering pump will fail if you run it dry too long. If it is low, fill the reservoir, and wipe down the hoses and pump before you start the vehicle, so you can find out a general area of where the leak is coming from.
