I received the high pressure power steering line from RiffRaff earlier this week. Good thing I went through him as I did not know that my VIN would decide on which hose to purchase.

I ended up getting hose 1c3z3a717aa from Clay and all went well.

The post by IDI-Charlie has me thinking that maybe I should have gotten the low pressure hose as well as any other hoses in that system and change them out while I was there.

Has anyone had any significant problems with the low pressure hoses or should I leave well enough alone?

It does not look damaged or worn, but it is 17 years old now.

I am on the hunt for the specific part number now for my truck, will be back later to see where I stand on this preventive maintenance item.

 

It's just a return line, Sous. Can't have THAT much pressure, if any, since it only has a small snap clamp at hydroboost fitting. I didnt bother nor bothers me to think that it'll blow....

 

1C3Z3A717AA looks to be the pump to hydroboost line. The other pressure line (hydroboost to gear) is Omega 1275 - I believe that is the one you are thinking about. Personally I'd say go ahead and put it on as a preventative measure.

Out of curiosity, what on your VIN dictated the hose? Nothing I see lists X VINs get this hose, and Y Vin's get this one.

 

Replacements are approximately 7 pressure hoses and 3 return for every 10 hoses.

Data coming from several million units over decades of sales.

 

Are you saying I bought the wrong hose that is prone to failure? I told Clay at RiffRaff that I wanted to replace the high pressure steering hose that is prone to failure and put all of my confidence in him.

Based on my VIN of 1FTNX21F0YEC20060 he said that was the hose I was looking for.

If you say that is the wrong or a different hose, then I will look into replacing them both at the same time. Let me know your thoughts.

 

Sous, here's a good depiction of the box and hoses. Number 5 is the one that rubs on the shock tower, it looks like you got number 6. Both are pressure hoses.

Well crap... I guess I will get number 5 on order and replace both of them when I get to it.

 

when I did my HP hose I just covered both with a piece of split heater hose where it passes by shock mount. 100k miles late no issues

 

Side note: When I did that #5 I had the fender liner out and accessibility was excellent and the other hoses were reachable, I don't know how easy things are from above. Fender liner came out fairly easily for me on this one.

 

If I'm not mistaken nbr 6 is the one that blows out and the problem area is the fitting that goes into the pump. That is the line I replaced after talking to several of the members here just to make sure I had it right. The others can be covered or protected like spongecop said. that would be only if they are even rubbing. Pretty sure Clay sold you the right one.

 

Disregard this post...

 

The snap ring inside the 16mm quick connect fitting fails and the tube spits out of the nut. That design is meant to speed up assembly line production as the nut can be ran in with a socket rather than a wrench. After the nut is in the pump the line snaps into the nut.

Great for assembly but often fails if disturbed. Mine failed 15 feet after my engine swap.

 

Not at all! I was saying that the second hose I replaced was the pressure line to the gearbox from the hydroboost vs being a return line. Sorry for the confusion. On my truck the one from the boost to the gearbox was the one rubbing on the shock tower.

I did mine from up top by removing the airbox, intake hoses, and the DS intercooler pipe. IIRC I used a 18mm, 19mm, 20mm, and a 21mm wrench, along with a 17mm crows foot to get the hoses off.

 

OK, so I will replace the hose I purchased then inspect the others to ensure they are not rubbing against anything and replace if needed.

Thanks for the help.

 

just like brandon said above, it will leak out of the nut. Hard to tell wether its 5 or 6 on the diagram but the one that is a hard 90 out of the side of the pump, then goes down and around the bottom of cac pipe. The cac pipe basically rubs right against the 90 degree fitting. I was trying to do some preventive maintenance earlier this week and put some wire loom around the 2 hoses that rub the shock tower, and low and behold that fitting blew out about 2 hours later while towing 10,000 lbs. No brakes and no power steering hauling 10,000 lbs, talk about puckered up! This should definitely be on the failure prevention thread. Could be life threatening if you dont change these lines out
