Rusted hubs!

[Chimpy]

Sorry I don’t have any pics but I would like to know that if you had to have hubs pressed out of the knuckles, was it expensive and will the new ones
need pressed in?
i started my front end project today. I was planning on replacing the CV axle seals, CV Shafts and hubs. Well, I can’t get the hubs to budge. I soaked them with PB Blaster and beat the holy snot out of them but they won’t budge. I remove the driver side knuckle with hub still attached. Going to have to do the same thing to the passenger side most likely. Every time I get involved in a project like this, it goes wrong somehow. LOL
Wish me luck. Lord knows I need it.

Use a BFH and soak with Liquid Wrench or PBB for a few days. Or remove the knuckles and have them pressed out by a shop.

Try hitting them in a way that will make them rotate in the bore.

I paid a shop $40 to press a set out, but the new ones popped right in without needing to be pressed in

I usually just drive a chisel between them on both sides and they always pop free.

Ended up removing the knuckles w/ hubs still attached. Had to have them pressed out and my buddy said it labored his press a bit. I replaced the axle seals, CVs and hubs. It rolls much smoother now; next up is the water pump/fan clutch, upper/lower hoses, and belt.

You can rent a hub puller from most AutoZone stores. It’s a big slide hammer that bolts to the lug studs. Rusted hubs are very common on H3s, and you often destroy the thin sheet metal dust shields when doing the swap.

Amazingly, the dust shields remained intact and I re-installed them.

The shop could not get mine to budge from the decade of Maine salt and brine so ended up ordering a new steering knuckle and installing both a new hub and knuckle. About $200 more that way unfortunately.

I know this is old, but wanted to give some advice for future people reading over. Mine was as stuck as you could imagine, used heat treatment, BFH, the pull bar from advanced auto, everything.

What worked for me was using an extension bar, through the backside of the hub assembly where the mounting bolts go into the steering knuckle. I would hit it 4-5 times hard as hell in the top one, then move to the next hole. I rotated through those holes and after about an hour it finally came out. I didn't use a crowbar once it was separated a little because I was trying to save the dust shield. Just be careful that when you get a little space, that you dont let the dust shield spin, because then you are just hammering the extension into the shield and not into the hub.

I'm not sure how hard mine were to pull. I went inside to get a glass of water and Reloader had them out when I returned. That seems to work for a lot of my repairs.

Water???

I can tell you on both the 06 & 07 had to beat them like red headed stepchildren to get those sob out. Man it was exhausting. On the old 06 I had to use the angle grinder and cut stuff apart. After that I learned to always grease the snot out of the hub edge before inserting and cover the area in never cease grease and fluid film kinda spray stuff.

before you put the new ones in, lightly sand the mating surface to remove the rust, put a light coating of anti-seize compound on it. you will thank me when you are needing to make a repair our on the trail. I have seen many a rig stuck on the trail just because they have never serviced their bearing unit and cann ot get it out to repair an axle or steering joint.
