I have a 2004 with the 4.6l. The high pressure hose is leaking from rust. From other posts I have read, it looks like I should rent a puller and remove the pulley first, and then I'll have access to where the hose connects to the pump.
Question: The leak occurred while driving home from vacation today. Went we stopped for gas, we noticed a shutter in the steering. I added about a 1/2 quart to the reservoir - there was still some fluid but foamy. I made it home, and I when I checked again the reservoir was empty.
Should I go ahead and replace the pump while I am at it? I wondering it if could have gotten damaged from low fluid. The truck has 190k so it's not like the pump owes me anything. Will it make any of the repair easier to toss out the pump too?
At that age and mileage I would definitely replace the pump as well, if you are intending on keeping it for awhile. Doing so will make line replacement that much easier. An 18mm crow's foot would be the ideal tool to use on the line fitting where it connects to the pump.
Food for thought. There entire system only holds about the one quart of fluid.
I've spent the morning pulling the pump and lines. Almost everything is disassembled except for the two lines that go into the steering rack. They broke off. I used a screw driver to pound off the plate that locks them in place (after removing the screw). So now the only thing holding the ends of the lines into the rack is rust. Any suggestions on how to get them out? I was thinking of maybe trying an easy-out.
Also, what is the thread size in the power steering pump shaft for putting the pulley back on?
Is there a way to put a little heat on it without messing anything up. My only advice is heat and vice grips. There doesn't appear to be enough metal for the easy out to grab. Best of luck to you.
At this point, my plan is to remove the whole steering rack so I can work on it. It doesn't look too bad (famous last words) - remove the tie rod ends, remove the knuckle to the steering wheel linkage, and then remove the two large bolts holding the rack up. Then I can put the rack on a bench and get the old lines out.
Next step - I'll need to get a 22mm gear wrench to remove the one tie rod end.
That's some really nasty rust there if you ask me. The lines are made out of steel. The body of the steering rack is made out of aluminum last time I checked. That said, I would just spray liberal amounts of PB Blaster, WD-40 or rust penetrant onto where the two broken pieces of the lines enter the rack, and work it out with progressive taps of a chisel, taking care NOT to damage the hole where the lines enter that is. If replacing the steering rack is not an issue with you, then this conversation is not necessary.
i did mine when i replaced my motor i used a flat head and pried on it and eventually i did come out but having the fan and plastic around the fan out because i had dropped a new motor did help the task a lot with more room to play with.
if you can bend the tube going in the rack it will loosen it and be easier to pull out
