That's what I do. Not worth the trouble and expense of repairing.
Probably not, but if I feel it needs to be pointed out to OP that if they elect to eliminate the vacuum hubs and go with full manual hubs, they need to cap off these vacuum lines or they will have other issues.
Anyone have a diagram of the knuckle axel assembly? Just came to a halt trying to get the axle out of the knuckle! Got by a rounded off bolt no problem but cat make a move past this point. It would be nice if there was a puller to get the seal out. Thats what wont move. This is all for a very loose lower ball joint. Looks like it needed to be replaced a long time ago.
From what I read, get a big, thick screwdriver and pound from the back going all around the seal. Spray the crap out of it, might help to unseat the suction. Got an "Air Hammer", you can use that too, from the back, going all around the seal. I'm going to do the same project in the winter time. Researching most stuff now and acquiring parts to do it. Ball joints, axle seal at the knuckle and seal at the axle tube. Going to change out hub bearing as the truck is 21 years old going on 22. It's a 2002 F-250 4WD CCLB with 235,000 miles.
Got it. Thanks. Turns out you can get a prybar in where the tube seal is. Then push on the bar and everything will slide out. needless to say the seal will be shot after that. Looks like you might be able to get a upgrade seal for the axel tube. after I get the ball joints out Ill let you know how it works out.
I put those on my '11. A short time later they were tink-tink-tinking around on the shaft yokes. Cut 'em off with tin snips and never looked back. That's just me, do what makes you comfortable
The seal on the axle side of the shaft is almost useless, it is intended to keep dust/water out of the axle tube. The actual seal is over by the differential. If you aren't fording a lot of water I wouldn't worry about it terribly much.
The important one is the big one by the knuckle, that actually keeps stuff out of the back side of the wheel bearing/lockout. You can either purchase the tool, or if you search the site you can find directions to build your own out of PVC pipe. You definitely want the tool, however, or you'll damage the seal and will need to buy a new one.
Because you didn't have the axle seals before you need to sand then polish the axles while they are all apart (no ujoint) best done on a lathe but you can do it with a bench polisher / grinder with polish wheels. You need to polish right behind the knuckle, where the seal is going to land. Then slather the seal with grease after you pound it into the axle tube. Slick the landing area up just before you put it thru the seal.
Build or buy the tool for the big seal, makes it way easier to install the seal on the axle stub and like said it will keep you from destroying them. Also get some like 1" sanding drums and holder and buff up the spindle bore, get all the rust out of there so the seal slides nice into place. Apply a thin coat of grease in there so when you go to seat the axle and push that seal thru the spindle it goes nice and smooth into place. Tool is your friend here to help you get it in there.
