Are you talkng to me Zmann?

 

You don't really need to pull the axle out if you are just replacing the hub. Although if the seals are leaking it won't hurt while you are there. The seals are not reusable so if you pull the axle go ahead and fork out the doe for ball joints and stronger u-joints too.

Suggestions:

*Take out the ABS connection in the back of the hub. Then get some mean green axle grease and a grease gun. Put it to the hole and hold it tight, pump the new axle grease into the hub and flush all of the old grease out. The ABS sensor in the hub works on the same principle as the cam or crank sensor and the grease won't hurt it. You can also repack or replace the spindle (needle) bearing if you pull the hub.

*If you don't have the special tool, lay the tire flat on the ground (inside up) and put the hub into the rim. Then take the new seal and the axle, push the seal on a little and make sure it is square. Use the back side of the hub and the axle as a slide hammer and pound the seal onto the axle. The drive side is harder because the axle is shorter, but just make sure your strokes are straight and the seal is going on straight. Same principle as the special tool, just a different solution to the problem.

 

just offering incase you wanted to make it available for everyone

Sorry took me so long to post. These were the numbers I used on my 04 when the auto hub would not engage due to a bad seal & worn knuckle seal.

Did my bearings/hub last week. If you buy the National brand bearing look around before you give Advanced Auto $330. I found mine myautopartswholesaledotcom for $230. National Part #515056, includes new o-ring/abs sensor and 4 studs....but I have an 04 so your part is probably different. Pretty easy once you do one side...if you have to do the other it goes even faster the second time around

 

They made changes to the hubs in 05 they arnt the same so far I havnt found any aftermarket hub assy for these years

 

great so i have to get them from ford? thats gonna hurt! thanks for the info so far. not going to be able to do it for a couple of weeks being that airdog took a crap so sent that off and next weekend i have family plans so cant do it then either

 

pjnadon,
Hard to tell without me looking at it & don't know what changed from my 04 to your 05, but you may not need the locking hub. You may just need the knuckle seal assembly behind the wheel bearing assembly.
My hub did not want to disengage when locked in manually & then unlocked.It also would not work at all in auto mode. It would make all kinds of noise when driving. The knuckle seal is actually more than just a seal. It keeps the stub axle centered in the knuckle on the u-joint side. I was suprised to find after tearing everything apart that there was nothing wrong with my locking hub after all the noise it made.
Someone had removed the seal and tried to reuse it. They had used some sort of punch all around the edge & pretty much distroyed it. This is why the required tool or a home made floor flange pipe set up it required to install it. Also my yellow o-ring was pinch and in 3 pieces. Hubs work good as new now in auto mode.

Your mechanic said it sounded like a bearing assembly.
Have you tried jacking the truck up and checking for bearing assembly play?
Put your hands on the tire at 12:00 & 6:00 and check for movement or noise?

 

had the truck in the air because i though maybe there was a chance it was the already warped rotor on the drivers side. so i replaced that and spun everything and sounded good. no wierd noises. put tire back on and drove it and the noise was still there. but the odd thing is when you press the brake petal it goes away. might here a slight noise but it is pretty much gone. if your on the brakes and listening for it you can here it ever so slightly but if not listening for it while on brakes then you dont here it. my girlfriend who doesnt know anything about trucks heard it the other day while driving so i know its getting bad if she hears it

 

In 04 they had the locking huds held in with a retaining ring where as a 05 06 has 3 screws holding them in from what i have seen in my ford dvd the knuckle seal is the same its just the hubs that changed Ford parts .com has them for $542. the 04 locking hubs can be serviced where as the 05 06 cant be .even when you search warns website they dont list any aftermarket locking hubs after 04. When I went to my local ford parts store they had no part # for the Knuckle seal

 

Like 00buck75 says pull on the wheel and chack for play if its in the front the noise should change when taking a corner. My 2002 dually had what i thought was a wheel hub noise I change one side noise was still there changed the other side still there ended up being my hanger bearing didnt find that out till it went

 

Are the knuckles the same from 04 to 05?
If so, swap on 04 bearing assemblys with the retaining ring groove and buy the warn hubs.

 

The site I mentioned in my last reply shows a National (Federal-Mogul) part#515081 for the replacement Wheel Bearing/Hub Assembly for about $370 for your truck (06 F350 4WD SRW). Free shipping. Not sure if that is your whole problem or not, but I thought I would let you know before you considered getting ripped at the dealership. If you find that you do need to replace the hub/bearing unit and you do end up going through the site I mentioned I have a 15% off promotion code that should work.
