Power Steering Return Line.

My Dream said:

My 2009 XLS power steering reservoir was very low and upon further inspection I noticed the return line rubber hose right after the reservoir as well as at the other end of the metal line, it was soaked with oil. Since the metal line in-between the rubber hose is in good shape can I just change the rubbers hoses at each end? If so does anyone know the size of each hose so I can purchase before disassembly?

Looks like they might be preformed hoses. One way to find out the size is to disconnect it and measure the diameter.

Thanks for the reply Avalon Limited, I'd like to avoid disconnect measure, then reconnect, refill ps reservoir so that I can drive to the auto parts store to purchase the hoses. I'd also like to avoid doing this in the auto parts store parking lot as I have all my tools in the garage.

I believe is I cut the hoses long enough I have enough room to play with. Hose clamp sizes are easy to figure out based on od sizing, I just need the inside dimensions.

I noticed Rock Auto has two options but the images of the hoses don't seem to match up with the Toyota OEM image.

My '06 Avalon XL has had a leaky return hose for some time. The leak is very small - I simply top up. I will eventually replace the line. Right now I'm guessing 3/8" ID.
My biggest concern is getting the hose off the connector pipe on the reservoir w/o breaking it.
The hose I'm speaking of is the one that's part of part # 44406 in the diagram provided in the 1st post of this thread.
I'm not too concerned about it being pre-formed. It's not all that long.

Thanks for the reply Mike.

We're both on the same page in that it's the 44406 line I'm referring to. In doing a search the Toyota oem part is around $75.00 not including shipping and tax. In my Avalon the metal (middle section) is in great shape, therefore I believe it would be more cost effective to replace the upper and lower rubber sections with new hose clamps. I just want to have the rubber sections available before I remove the 44406 part as I'm not able to drive to a parts store with that section removed.

As it stands now the best guess is by Mike Murell at 3/8" id.

PS. I'm dealing with a 09 so I'm hoping the reservoir is not as brittle as your 06. With that in mind, I don't believe my connector pipe will break.

Just curious if you were able to figure out how to replace the hose by itself? I have a similar issue and it seems silly to replace the entire line when only ~$2 of hose is needed.

If memory serves me right, I replace the rubber hose only and installed two hose clamps at each end for added protection. I haven't had any leaks so far.

This small preformed hose was listed on the Rockauto website. They pulled it off the page a couple of weeks ago.

I remember researching this on Youtube and other sites, I believe the consensus was that the hose come as one complete part with the metal lines, and the hoses themselves aren't normal hose sizes.
I also remember someone saying that regular line at the autoparts store couldn't handle either the pressure or the chemical make up (can't remember which) and would leak relatively soon again.
Some people did have luck replacing the clamps with screw clamps

Thanks so much everyone for the quick feedback. I spent way too much time trying to find a matching hose and finally gave up and ordered the full edelmann assembly for ~$50.

How did the full edelmann assembly for ~$50 work out for you?
