Ford 7.3L Power Stroke (1999-2003) :: Replacement Hubs - How Are They Holding Up
Aug 4, 2016
To those of you that have replaced your unit bearing hubs on your 4 x 4's; are they giving comparable service to the OEM units? I'm replacing ball-joints right now and it would sure be easy to slap on some new hubs. The only issue is I have 130k on the originals and have been lubing them through the ABS port for the last 20k miles - the hubs seem to be in good condition. I've noticed some posters stating that since lubing an already good hub, that they are now getting a lot more than the standard 150k out of them. I also worry about replacing perfectly good US bearing hubs with most likely a Chinese bearing hub (Timken or not!).

Warn Premiums, installed them and now the 4x4 is engaging, but still have a grinding issue. When the hubs are locked and the switch is in 2 wheel drive, the frond end is grinding, if I switch it to 4 hi, the grinding goes away.

I have my vacuum system back up and working and using my vacuum pump I determined my lines are all good. They hold a vacuum fine, but my ESOF isn't engaging my hubs. I guess that leaves either the selector on the dash or the seal at the hubs.
If it is the selector, I should just be able to just disconnect the vacuum line at the selector and use my pump to engage my hubs. How much it is supposed to take to activate the hubs?

I am thinking on installing a shutoff in the vacuum line that supplies the hubs so I can use 4LO for backing uphill with a trailer without having the hubs engage. Its either that or a switch to disable the PVH solenoid.

As my truck stands it has OEM automatic locking hubs with a selector for auto or lock. So, why would some one buy manual locking hubs and cap off the ESOF vacuum line when the OEM ones perform the same function by being auto or locked?
I hope this makes sense because if I felt I wanted to go to manual style locking hubs, I think I could simply cap off the vacuum line and then switch the hub to lock if I wanted 4x4 because the electric switch inside the truck is actually what engages the transfer case and puts the truck into 4x4.
Is this thinking/theory correct or am I missing something here?

I was getting a growl/grinding noise from my front hubs (driver's side I think) when I do a slight right turn like going around a curve, not turning around a corner. Just started happening the last week after returning from a 4th of July roadtrip. First thought was wheel bearings going out and started reading up on the forum here to see what was needed. Last night, I started getting a continuous growl when I was 5 miles from the house so just pulled up and parked it. I'm assuming (without pulling anything apart), it's the bearing assembly and I can get the Timken version at Autozone locally.
The problem is I generally do my heavy maintenance at our family shop in San Antonio but I live in Austin so will need to do this in my driveway. I have all the basic tools, just need to know how involved it is to do in a driveway instead of a shop. Thoughts?

I know this is going to sounds lame, my wife can't turn them, they have cover over it that has to be unscrewed to get at 'em. It would be nice to shift in and out "on the fly" as weather condition change.
Is it a difficult change?

My transfer case engages the front drive shaft spins but even when I manually lock my hubs neither of my tires will pull! I was thinking either the hubs are shot but I was told it could be the 4wd locking solenoid??

I have 1999 F350 7.3 Crew Cab 4WD. I took it on a 4 hours trip towing a trailer to haul a small tractor on it. after 3 hours of driving, I started hearing grinding and metal chewing sound coming from the front axle or close the wheel hubs. It was awful, terrible, ... you name it!!! I had to continue or I will lose the tractor I paid for already. The sound was coming for 1-2 seconds each 500 feet or so. It never stopped or changed. I pulled over to see what's going on and found the following:
1. Left shock is leaking badly
2. Right locking hub is gone (not sure if the truck had one before). I bought this truck last year, but I never had to use 4x4 and I know the 4x4 motor by the transfer case is missing and the nipple on the transfer case is set to the 2wd position so the front drive-shaft does not turn.
I took the front shock off and continued to drive without it, the noise did not go away.
I pulled over again and this time I noticed that the dust cover on each end of the front axle is missing too. I have never worked on these axles before, but I jacked one side, and sure enough, gear oil was leaking from the other side. I took the plug off the front differential and stuck my finger in it. I felt a creamy brown-greenish stuff in the differential. The consistency is like mayonnaise or thin peanut butter. I put the plug back on and went to pick up the tractor because I did not want to miss it fooling around with the truck on the highway.
The truck made it there and back (almost 5 hours total after the break down). The sound never stopped every 500 to 1000 ft.
After getting home safely, I took the other locking hub off, and took it for a test drive. I did not hear the noise, but now my right brakes are locking.
I took of the wheels and saw that the retaining snap ring (C clip) for the front axle on the right side came off by hand. I took the washers behind it off. Took the calipers and brackets off. I have never done front axle rebuild. I am not sure what has been damaged and what's still good.
Right of the bat, I know, at least, I need 2 shocks, one brake caliper and pads.
My questions are:
1. Is it possible to take the front axles off on both sides and make it 2wd for now until I have the money to rebuild the axle?
2. Could I use the same hubs? or they are most likely damaged and how to tell?
3. How to tell if the differential is damaged/needs rebuilding?
4. How to tell if the axles/spindles are damaged?
5. Is there a step by step tutorial to rebuild the axle with all seals, bearings, ...etc? How hard is the job for a hobbyist? I do most of my repairs myself, and I was lucky at 36 years old, I never had to rebuild a differential.
6. What else I might have damaged in the process of driving it that long with the noise? How do I tell if I did?

I'm in the middle of replacing the hub and bearing assembly, once i got the hub assembly off, I noticed when I grab the axle there is a lot of play if I pull the axle up and down or left to right. Is this normal as the hub assembly holds it in position? I don't have any fluid leaking so the seal must be good, or am I missing something. I am trying to do this in 30 degree weather and it sucks.

I have a 99.5 with 400,000. on the engine. It has been a great truck but it is time for the some TLC. I have a little leak on the radiator and the water pump and would like to replace it. I am just looking for stock.
I have a 13 yr old that grew up sitting on my lap as we drove the dirt roads around the house and on the ranch. He has been driving this truck by himself (on the ranch) as soon as he was able to reach the pedals, around 8 or 9. His happiest day will be when he gets his drivers license and can drive the truck to school. So I have a lot of work ahead of me on this truck.

Rebuilding my 7.3 and I'm in need of the removal and install tool for the injector sleeves/cups for the 7.3 Powerstroke Diesel.
I'll pay all shipping charges and a small fee if required. I hate purchasing a tool I'll never need again, rather better not need.

So i bought a Aluminum Flatbed to replace my rotted bed. Its about to blow off going down the road at this point. The new Flatbed is Aluminum with LED lights. I suspect i will need to wire in a load reducercorrect? Also this bed has no fuel spout so i need to fabricate something. I also plan on installing underbed tool boxes if there is space.

I need to replace the cable on my gear shift indicator. Of course you can't just replace the cable. I have even looked on you tube and not found anything. I don't know if maybe I am using the wrong search terms or not.

My oil pan has rusted through and is beginning to leak. Can replace a 7.3L oil pan without pulling the engine? It looks like if I remove the turbo and fan clutch, I should have enough clearance to lift the engine several inches and get the pan to clear the crossmember. Or would it be easier to just pull the engine?

I will be changing all the glow plugs in a few days. Should I re-torque the head bolts or anything while I am in there? Don't want to button it back up and then wish I had done something while in there.

Got new batteries installed yesterday and found that the passenger side battery has a nearly broken positive terminal. Had to handle it very gently.
Don't want to replace the entire battery cable just to get the terminal. Using bolt-on replacement terminals? What did you go with and where can it be found?
