Possible power steering issue


Recommended Posts

Hello,

Noticed when I started my cat yesterday and slightly turned the steering wheel a strange vibrating and whining noise. Will ring the mechanic on Monday but was curious what it might be?

Thanks,

Dave.

Don't know about the cat 😉

But you could check the power steering fluid level in your car.

I am not sure of the system on your car but any leaks could mean air is introduced which might be cause of vibration.  I remember changing the oil on my old V6 2.5 Camry which had a conventional power steering system.  On this to the best of my memory, I had to jack the front wheels off the ground and turn steering several times from lock to opposite lock to remove air out the system. I don't remember if the car had to be running or not (it was back in the late nineteen eighties) but most likely with engine running).  I did the job according to Toyota workshop manual and it worked fine afterwards.

Sorry to drag up an old thread but I've noticed my PAS not working and noisy for a few seconds after cold starts recently.  Had a dig at it yesterday and it looks like the PAS pipe that runs down the drivers side chassis leg has corroded through and is porous.  Going by the fluid gathered on the undertrays it's probably been an issue for a while.

Has anyone replaced this?  Looks like it could be a bit awkward for access.

Also I think it's number 44416 in this diagram:

LEXUS RX300 330 350GSU35R-AWAGKW - POWERTRAIN-CHASSIS - POWER STEERING TUBE | Japan Parts EU (japan-parts.eu)

Is anyone able to confirm for sure?

Many thanks again,

 

Jay

It's a bit difficult confirming that that is the correct pipe that is leaking on yours, as you are the only one that has seen it...!!

So my mechanic suggested trying this. Had it in the system for about 2 weeks and nothing improved. Rang him on over the weekend and he said there was some other stuff he used previous that worked. Went round Monday and he removed some of the hydraulic oil and put this Lucas powered steering treatment additive.

Must admit as the first on didn't work I was cynical. Spent 5 minutes turning the wheel left to right etc. It's perfect like new 👍

Fingers crossed!    Excellent news Dave, hope this resolves the issue.

(I can't help but wonder how the 'remedy' works, and if there's a downside to it

Unfortunately access is tight and the diagram isn't great Peter. 

Thought someone may have encountered the pipe on the drivers side chassis leg rusting before so figured I'd ask before I get balls deep in power steering fluid 😄

Because I can see the porous metal I'd prefer to replace it rather than add treatment, don't fancy pushing the problem down the road as it were.

Will update if/when I get an answer!
