Thanks Russell. The back of my mind keeps telling me there is no "snake oil" fix.
Twenty bucks for a hose is cheap.
I thought if I took out the inner fender it would be easy to get to.
You want to work on my truck?

Using ATF isnt "snake oil". ATF and power steering fluid are identical in base properties. Swelling polymers with fluid is a technology that has been around for many years and we use it extensively in oil/gas wells as well as a lot of o-rings you see are designed to do the same. I'm not trying to discourage you from getting a new hose John. Just wanted you to understand that swelling polymers is not a "fix it in a can" or "snake oil", its a normal chemical and polymer reaction that doesnt hurt anything. It makes my company over $300M a year. Anywho, if the hoses are that cheap and easy to change on these newer trucks then by all means get a new hose.

I understand what you are telling me Tracy, And it makes sense.
I am goint to try the synthetic ATF for a week. If that does not work, Then you and Russel can change out my hose while I drink a cold one!

Cool. Thanks Russell. I'm going to try Tracy's way first and see what happens.Then we (You, myself, and Tracy)can replace the leaky hose.
Any Bets?
Maybe it could be on the casino section!

*Update*

Been using Synthetic ATF for a week now. It is still leaking.
I went to the dealer today and purchased the high pressure line that goes from the power steering pump to the brake booster.
Real busy this weekend, Dont know if I will get to it.

You might want to run your VIN at the dealer. There was a recall for the booster to pump steering lines. I can't remember the specifics or the years. There's a julian date on the hose you need to find.

Or PM me your VIN and I can run it.

Thanks, I have the line. The dealer did not mention a recall.
