Hello again: Just finished the P/S Flush...After I added some brain cells, I figured this out... Took 20min...Very Easy and Clean... My 16yr old son helped me with brakes and steering wheel... Since I have been a life long Amsoil User.. as well as M1...I checked prices...Both are over $10qt...That's Crazy...Amsoil was even higher with shipping... I used 4qts to make sure total flush...Nice Ruby Red ATF was flowing at the end of the flush... 2qts Valvoline Mercon V & 2qts Valvoline MaxLife Merc/Dex... With a little extra room for 10oz of Lubegard ATF additive... P/S is like silk now--{Smooth and So Quiet}...
I just ordered the Magnefine 3/8 P/S filter will install up close to the hydroboost on the same line I had to remove... Will Change it out every 2yrs... and do the flush every 4yrs... From here on out... The main reason for doing this flush is I have plans on keeping my 7.3L for many many yrs too come... and If it helps prolong the life of my P/S unit... It was well worth the $25...
Thanks again!! Next flush I will pour in Synthetic ATF to help with those cold winter months...
Admin reply: Glad you got it done, Lonnie. I am like you, I intend to keep my 7.3 a good long time. I think if good maintenance is done, it is more than possible.

Hello again: I hate getting older... Memory is horrible...
Can you give me any incite on how often you change your magnefine filter on you P/S system? If you still own this truck...
Thanks Again
Lonnie
Admin reply: I do still own the truck and change the filter every other year.

Hello: I have done routine maintenance on every fluid within my 01 7.3L except the power steering pump... Which I know after 286K miles needs it... The Pump still so far works very well... No Wine--Very Smooth...I have sucked some of the old ATF from the plastic res itself and replaced maybe 1/2qt... but never a total flush... Now here is my question---->
I attempted your awesome P/S flush method... Very Easy and Prompt...But my neighbor had my floor jack and he wasn't home...So No wheels off the ground...Now! This is where my patients runs out...LoL! After about 1hr of idling my 7.3L-{Which I hate to do}... I only had about 1/4 of a qt in my drain jug... Will the ATF flow out faster if I have the wheels raised and turning the wheels from corner to corner? I hope so this was ridiculous...
Not bashing your write up! It was awesome...And doing this flush I think is very critical if you have plans on keeping your truck for many yrs like I do...
How long did it take you to flush your system?
Also I will add the magnefine trans filter at the time of my next flush, which will be right after I hear back from you... After seeing all the black nasty residue within the res, this is a must do filter...
Thanks for all your knowledge and time to write all these for guys like us...

Admin reply: Hello Lonnie,
Yes, you really need to raise the wheels and go clock to clock. The fluid barely moves if you do not. The whole process should only take ten or fifteen minutes.
Good luck.

I need some help. My front axle is spinning while I'm driving causing the passenger side only to leak. I replaced the dust seal on the axle, the seal behind the hub bearing and the hub bearins on both sides. the ball joints are good. I can not spin either side of the axles without using a screwdriver/prybar. While driving at low speeds the axle doesn't spin, it seems to only spin at higher speeds. When I pulled the axles to replace the seals the tubes were dry. The vacuum lines for the "Auto" hubs are disconnected and plugged. Any help would be greatly appreciated!!!

Great site, just wish I could use it for the 6.0. I found your site looking for power steering fluid flushing tips and noticed that you have a Franz installed on your truck. My Father has been using Franz oil filters since 1963 on ALL of his vehicles. We were considering putting one on my 6.0, but need mounting ideas. Do you know anyone who has put one on a 6.0, and if so, where and which model, single or two stacker? Thanks

Great write ups, I had a son broke down on the interstate with a bad front wheel bearing on a wildland fire truck. I sent him some of your images on the disassembly of the front hub and he was able to replace the hub unit bearing and get going again with only a few hours of down time.
Admin reply: Richard, That's a cool story. Thanks for sharing. I'm glad your son was able to get going.

Wow!, your write ups are amazing. I like many had just stumbled onto your site. I was having a hard time finding the axle seals in the front. That was until I found your site. I do do all my work myself. The axle seal seating tool worked perfectly! Keep up the great work and write ups!
Thanks!,
Adam

Thank you very much.
I stumbled on your site by chance looking for part numbers for a current repair project.I have a 2003 7.3 PSD that I bought new with 220 miles on it and have just rolled 250,000 miles over. I have maintained and preformed all repairs because our local FORD dealer charges suggested retail price on all parts. And has the highest shop rates. ( very small town ) . I have been buying parts on line for years from FORD dealers but have found there sites do not always make it easy to find parts. So do a lot of looking to get ford part numbers as well as looking to build tooling to do the jobs. Wish I would have happened on you page years ago.
Again great site layout and even better information!
Admin reply: Thanks for taking the time to post. Your experience is much like mine. That is how/why I began compiling the numbers. I do all my own work too. I like doing things just so, and therefore prefer to do most things myself.

Hey there. I just read the article on replacing the ball joints in a super duty. I'll have to say, very very helpful and keep 'em comin! I have one question: when you remove the old knuckle seal, there's a metal flange that sets behind the seal that comes off with the seal. The problem is, I damaged mine beyond repair not knowing that I couldn't get new ones. The only way to get new ones are with a complete outer axle, which I don't need. However, I noticed in the picture of the new seal after installation, that the metal flange was not reinstalled. My question is, do I even need to put the flange back on, or is it OK without it. Any input is much appreciated. Thanks
Admin reply: Hi Rob,
I think the flange you are referring to is part of the seal. That is, if we are talking about the same thing??
