Hub Replacement


Recommended Posts

Posted

I need to replace the right front bearing. Had everything apart but could not get the hub to budge. Soaked it in PB, pounded on the sides of the mount and even tried wedging it out with an air chisel but all that did was mash the metal, couldn't get any separation. I was using an underpowered compressor though. Is it safe to pound the back of wheel lug plate or would i be taking a chance that things would blow apart leaving the mounting face of the hub still attached to the steering knuckle?

 

Thanks

I just replaced my RF. Like you, I soaked everything with PB Blaster. I pounded on the back side of the flange. You've noticed that there is no way to pound it anywhere else but there without eventually destroying your brake backing plate. I used a small 3 pound hammer and struck the back of the flange at what would be the 9 o'clock position as you face the hub. I was afraid that it would get cocked in there by only pounding one side but it slowly came out after dozens of blows. You'll want to replace the axle nut too. I got mine at O'Reilly's for just a few bucks. Luckily, I had a 36mm socket for my Corvette because the new nut needed the 36mm and I believe the stock nut needs a 35mm socket to get it off. I think there is an SAE equivalent that works....maybe on both nuts.

 

FWIW. if I had it to do over again, I would get a good, sturdy 3 jaw puller. I think if I could've applied even outward pressure, it would have come out a lot easier. Good luck.

Thanks, i'll give it a go this weekend. Grinding was bad today, probably because i was hitting it so much last night. Just to be clear, you pounded on the backside of the brake backing plate (you called it a flange) to hammer it out, or by backing plate were you refering to the dust shield/shroud, or whatever it should be called? Thats the one thing i hadn't tried, like i mentioned, didn't want to do some irreversible damage that would leave me stuck in the barn last night. My axle nut's 1 3/8 and its tight, no play in the socket head so theres your sae equivalent.

 

Thanks again, i'll post the results.

Sorry I wasn't more clear. I pounded on the wheel stud flange from behind. I did alternately turn the steering wheel to the L and R in order to attempt to hit the flange at the 3 and 9 o'clock positions but it wasn't getting me anywhere. If you turn your wheel a hard left, you can get in there and really whack that flange. My air chisel couldn't budge it. As for the backing plate, I may have called it by the wrong name. I meant the thin dust shield behind the brake rotor. I didn't notice what year you were working on.....I may have spoken too soon!

Nope you're bang on, and it's an '04. I just needed it to be clear in my mind that i wasn't about to hammer away at something i shouldn't. Nothing i hate more than not being able to finish what should be an easy job. It takes all of 20 mins or so to get down to just the hub and last night i was pounding for a good hour and half just on the hub. I was not happy but at least now i've got the weekend to play.

 

Thanks for reposting.

Did you remove the axle nut?

 

That needs to be removed first. Then I would loosen the hub retaining bolts on the back, but not remove them. Maybe leave them 1/2. Then hit the heads of the bolts with a 3 lb sledge. Works every time.

    • New to diesel trucks. I happened to find my oil cooler leaking oil externally with only 4,000 miles on the truck. I didn’t realize this was an issue until I started researching it. Dealer is going to replace it under warranty but I’m wondering if there’s anything GM is working on to fix this issue. I’ve heard the oil filter used is the same as they use on their V6 motors and that’s what is causing the problems. Should I switch to a bigger filter or keep using the OEM recommended? 
    • So, GMCustomerService:  Judging by the Update History pictured above, is this truck missing any updates that it actually needs. If it's just for the infotainment system, the radio is working fine and no trouble with SeriusXM. and Android Auto is working fine wirelessly with my phone. Some months ago, an update notice was sent to my truck. I approved the update and it finished saying that the update was successful, but it seems that whatever that update was, it didn't actually get installed - at least not if I'm to go by the Update History shown above.   So, again, are there any updates that this truck really should have? I've checked with my dealer but they're reluctant or commit to anything and if I want them to check, they require a $200.00 fee just to check it out and then I'd have to pay for the actual update(s).    Ignorance is bliss, and if none of the updates goes to fixing any mechanical discrepancies, I'll just leave things as is.  
    • Hey everyone, I recently had an issue with my 07 2500HD GMT900. My DRL’s stay on at all times. Right front turn and right mirror turn signal indicator stay on solid at all times. By “at all times” I mean the only way to make them go off is disconnecting the battery. I tore the headlight assemblies out, tried disconnecting the harnesses to eliminate bad wiring at the harness, I unplugged the headlight switch, no change and the mirror turn signal still stayed on. My first thoughts were : Bad bulb and/or socket somewhere, under hood fuse panel bad, bcm bad, tail light or trailer wiring problem, or some random short to power in the harness.  Possibly a bad ground but unlikely. I had a big clue in the fuse panel, it had a burnt smell. I started pulling every fuse that had to do with DRL or right turn/park lamp. Nothing made the right directional turn off but pulling the DRL2 fuse made the DRL’s go out.  After studying wiring diagrams, I found that both problems had that fuse panel in common, the bcm also controls both problems but knowing the fuse panel had a burnt smell I removed and disassembled the fuse panel and found a little corrosion on the printed circuit board.  I ordered a new fuse panel from Amazon for like $260. When it arrived I installed it, and put everything back together, the problem was fixed. I figured the fuse panel needed to be replaced anyway so that was a logical place to start. Hopefully this story helps someone in the future. Regretfully I didn’t scan for codes before I did everything.
    • That stinks. I’m sitting on the side of the road right now with the same issue. Never had an issue before taking it in for the ground strap recall. Now I’m outside of warranty and they’ll probably want $200 just to diagnose what they already “fixed”. 
    • I wonder kind of nuts and bolts they will come up with next? Jim
