Its going to be unseasonably warm today in Cleveland (mid 50s). I have new hubs and it seems like I should do them tonight rather than waiting and have the weather turn cold.

 

I have the factory manuals and appropriate tools. I believe the procedure is pretty straight forward.

 

Just looking for any tips/tricks from anyone who has done this.

 

Looks like the procedure is:

 

1) Jack up truck

2) Remove front wheels

3) Remove calipers

4) Remove rotors

5) Disconnect ABS wiring harness from hub

5) Remove hub nut

6) Remove three bolts retaining hub

7) Break hub free - remove old hub

8) Reverse procedure with new hub, torque fasteners as specified

 

Anything I'm missing?

If you have any problems getting the axle shaft out of the hub, you CAN screw the nut back on until it's flush with the end of the shaft and give it a good smack with a dead-blow hammer. It IS done this way at dealerships. It's also faster than a hub puller.

Good advice. Thanks 95Sierra

when I did the hub on my cadillac I cut the ABS sensor connector on the hub side off and left it connected to the plug until I was ready to plug in the new one.

 

Keeps any dust and dirt out of it until you're ready to install it.

5) Remove hub nut

6) Remove three bolts retaining hub (would probably be easier if the drive axle was removed first)

7) Break hub free (cuss liberally during process)- remove old hub

8) Reverse procedure with new hub, torque fasteners as specified

My hub took a serious and I mean SERIOUS beating with a number of chisels.. and a torch and pounding for about 4 hours .. my fingers are skinless and sore. this was with 2 professional engineers with tons of home mechanics experience.

 

the backing plate was mangled by the time I got the hub off the knuckle. I pounded it back to as close to the right shape as possible but was still a mess. I tried to assemble the new hub, but one of the bolts got hung up on the lip of the hole on the backing plate..

this ended up stripping a thread on the bolt.

So I need to now go buy a bolt and clean up the threads on the new hub. I also need to get a new backing plate.

I Think that this was not the original hub on the truck. the bolts were a little beat up from a previous job. The lack of anti-seize has caused me major grief.

I would like to take the hammer and chisel to the guy that did the last job. grrrrrrr

 

anyway the mounting for the HUB is just plain bad engineering, the bolts are hard to access. there is no pry slot in the hub nor in the knuckle, totally just cheap assed bad engineering.

 

With the number of bearing that are failing on these trucks they should be easily serviceable parts.

      This is a really late reply but I just found this thread. They won't sell the hinges. I've gone 7 rounds with them. Their solution is to buy a new cover. I'm about to buy a new cover and it won't be a Bakflip. It also won't be from realtruck.com.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver.

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.
