How to replace your 2wd fron Hub


Recommended Posts

Posted

Well i recently determined that i needed to replace the front hub on my 2001 Tahoe and I wasnt able to find much "how to" information on any of the sites that i looked at so i decided that i would do a little write up to give a general idea of what you have to do to replace your hubs.

Hopefully this will give other do-it yourselfers a idea of what you are getting in to and what kind of problems you may run in to along the way.

 

disclaimer: I am no GM tech, and i accept no liability if you do this yourself and a wheel falls off after you are done. If you do not feel comfortable doing these kinds of replairs then please dont attempt them.

 

Ok so you have taken your wheel off and now you are looking at your caliper / rotor

1st go ahead and unplug the wire that is snaked up your a-arm, it is to the speed sensor that is built in to your hub

unbolt the bracket on the top of the knuckle that holds down the brake line going to your caliper

(i didnt do that 1st but in hind-sight it would have made things a little easier)

Next unbolt the caliper from the knuckle, there are just two bolts that hold it on

Now you can slide the caliper off of the rotor, move the caliper to the left of the a-arm and use a zip-tie / wire hanger or whatever and get it out of your way but dont let it just dangle.

take the rotor off and now you have access to the hub

now you can unbolt the hub from the knuckle, there are only 3 bolts that you need to take out.

At this point your hub is free to come out.... kinda.

Mine didnt want to come out easily and i ended up "tapping" it out with a hammer by hitting the outside edge of the hub from all different sides and angles; it took a little bit of time and a few hard swings but it finally came loose.

At this point i used sanpaper to clean a little rust from the center of the knuckle, i sprayed a little wd-40 in there and the new hub went in with ease.

 

Now you can just reverse the process and put everything back together again.

 

I would suggest using some kind of lock-tight on the bolts to make sure they dont vibrate loose, also i would suggest using a torque wrench and making sure those bolts are in there tight. I am not sure what the torque specs are but i am sure a tech could probably tell you pretty easily.

I torqued them all to 100lbs (which may have been too much) but i did not want them coming out

I'm impressed and you deserve recognition not only for your efforts, but for your point in the lack of "how to" available. not saying it isn't available but its hard to find unless you get lucky on various websites or you buy a book...

 

Torque specs are important and many charts are around for different grade bolts ....it ain't no erector set because your safety and safety of others is on the line if you guess.

    • Getting greedy...   The AC pump has been replaced at least once per service records, and it's been recharged twice since 2018 or so, in approximately 2 year intervals between those charges.   It was done at the same shop...clearly they were enjoying the revenue of recharging the system periodically versus actually tracking down and fixing the leak. I learned that the owner was 88 years old when she passed in 2023, so maybe they assumed only a temporary fix was needed anyway.   The system is basically empty now, the compressor spins freely, so I'm guessing it "just needs a recharge".   I vacuumed it down, and it has basically held overnight. Doesn't appear to leak under vacuum, check! So it must leak under pressure. I don't have a way to pressurize the system and pressurizing it with shop air wouldn't be great for the air dryer (which is probably toast anyway?)   The dryer (accumulator? I'm not an AC expert) has a Schrader valve, but the high side has an old ball-type valve, which are notorious for leaking. It's clearly had schmutz blown out of it at one point because the line/area next to the valve is coated old black crud, which I assume is AC refrigerant residue/oil, or maybe even dirty dye. I think I'll roll the dice and replace the valves. I have a black light around here somewhere so I'll find it and shine it around the engine bay in the dark to see if there's any dye.   I can't think of another way to track down the leak other than injecting some dye (if it doesn't have any) and having it charged up. We can't buy R134a off the shelf here anymore, so I'll run it up to Jiffy Lube and have them do it. I think I have a coupon. At the very least, the charge should last long enough for a year or two, according to history. I think this truck will be long gone by then. But cold AC is a selling point.    
    • Got the truck back today.  Called them yesterday to get an update, and miraculously my truck is finished?!?! The $13k out the door was complete bullshit!  Ended up being over $14k.  They added some bullshit service bulletin that I cant even find, where they replaced my radiator without telling me or asking me, and charging me for it.  Need to do more research into it, cause they leaked the first delivered radiator was ran over by FedEX.  Sounds like bullshit to me. 2.5 Months for an engine swap, which ended up being remanufactured, not new; ****ing ridiculous.  Brakes are squishy as hell, not sure if its from sitting.  Will give a couple days to see it that figures it self out.  GAVE IT BACK TO ME WITH 1 GALLON OF GAS!  Just filled the tank the day before drop off, more bullshit.  My dash cam SD card was formatted, not really much I can do about that. 3 year, 100k GM warranty at least.  Time to sell it and say **** off to GM.  Bad experience.  Cant wait for the survey email to come through.  Overpriced Raptor R, here I come!
    • If I forget the phone in the truck, and forget the truck in the phone, and reconnect.  It works great for the day.  Truck sits overnight, and the next day is a no go.  It will connect Android Auto via usb cable, but not bluetooth.   Ive tried Everything in this thread so far, and nothing works for more than a day.   I think I might have to go to the dealer and have them flash the pcm.   thanks for all the suggestions guys. 👍
    • 2022 2500HD Crew Z71 Duramax single alternator.  Recently had the primary (water pump / fan) belt tensioner pulley bearing to fail while hundreds of miles from home of course the plastic pulley melted and belt shredded which took out some wiring. Found a replacement tensioner assembly and belt to continue now would like to find a replacement for just the pulley and bearing to have a spare assembly in case of a repeat, the rest of the tensioner is fine. Has anybody here found a correct replacement part for just the pulley and bearing? Any help is appreciated.
    • +1 for the 3.0   Perfect for 1500 pickup towing duties.   Perfect engine for a 1500 pickup period. Huge torque at stunningly low RPM makes it feel a lot lighter than it is. The fuel mileage is insane for a tall and heavy 1500... 30+ on the highway. Mid 20's around town.   It's probably not perfect if you bought a 6.2 for the braaaaaaapppppp V8 noises and wrapping it out to 6k. The LZ0 acts and sounds like a small turbo diesel and there's nothing you can do to make a small turbo diesel sound like a big one, and you can't make an inline diesel sound like a V8 diesel/big Duramax. It's a different driving experience altogether.   Drive one, I think you'll like it, though...
