OK my 2000 GMC Sierra half ton with 120000 has finally had a break down. I have absolutely loved this truck, up till now it has never broke on me so by no means am I mad but I have never changed the Wheel Hub Bearing Assembly. The front right is shot and need to be replaced. I have the part but before I get into it I wanted to ask someone with some experiance what if any special tools I will need to do this. The assemblt looks pretty straight forward but everyone knows what they say about assuming.

 

Any help would be great, Thank You

As long as it isn't rusted into the knuckle, it is a very straightforward process. Remove the wheel, remove the caliper, remove the hub cover, take the nut off of the CV axle (if it's a 4wd) that holds it into the hub, unbolt the 3 bolts on the hub assembly, unplug the ABS sensor, pull the hub out. The "pull the hub out" part is what gave me trouble, since like everything else on my truck, it was rusted to hell.

 

The only tool I needed to buy was a 36mm socket to take the nut off the CV axle.

Dan described it pretty well,I've replaced both ABS sensors and later both rotors and although a little time consuming can easily be done in your driveway.Air tools are a big plus when doing this work.I use mine alot.

Sounds easy enough. the 36mm is something that I dont have so that was especially good to know. Thanks alot for the response.

OK, job accomplished. The basic job of changing a bearing assembly is very easy. Its just that damn michigan rust that is a pain. Really had to heat it up and use a very big hammer to separate the two peices.

 

I just wanted to post this incase someone else needed to do this job as well.

 

Once again thank you for the help.

Hello all, new here.

Mine's gone bad also, heading down this road soon.

However I'm considering rebuilding the hub by replacing the bearings to save a few hundred bucks.

I know it's gonna be a little more work, but hoping not too much cursing happens as we've got a huge press available.

 

Anyone tried this already & how did it go?

Will the anti-lock sensor be a problem for me?

      Is 2027 GMC Yukon Getting a 682-HP Supercharged V8?

      By CaptPat51 · Posted

      Would you supercharge the 6.2L on a 2021 GMC Yukon Denali XL with ProCharger?.... 605HP is the stated number without going crazy - it's not the LT4 682HP package, but I'm tempted to install it... This vehicle was ... not... recalled on the engine swap - but I don't really know if that means ...don't do it... or do it;)    Maybe i should start a prediction market pool on it in case it blows up;)   Any thoughts appreciated - I already OWN the supercharger - stopped the installation when the recall was announced and now it's taking up space in storage until I can solve an electrical issue with the vehicle...  4th GMC suburban-equivalent truck - I like them a lot - when they don't a) discharge their batteries randomly, or b) throw a rod at highway speeds;)

      We tested the sleep mode with an ammeter in series with the negative battery terminal - 30amp fused - so we do know the actual shutdown and non-shutdown current draws and timing of the shutdown sequence.  We just have no protocol information to determine what module is issuing the network keep alive.

      Brake Pad Warning Message

      By Vu1can · Posted

      TrueBlue...Even if you don't have that info stuff displayed, If Mr. Computer thinks there's something you should know about, it will pop up a warning message no matter what else is being displayed. I keep the speedometer displayed all the time, yet the brake pad message pops up anyway.

      BTW, the 11.5amp draw is all the usual systems active - it's not a single draw - that's the "we're all awake" state of the vehicle - forinstance if the power steps are actuated, the draw will spike to 22amps for that operation.  when the battery is disconnected and then reconnected, the vehicle shuts down that one time only - and we see a 10-15minute progression down 11.5  10.5  9. 8 6. 5. 1.6... 500ma... and then off to sleep at 40 milliamp... as expected.  So we know it's a module that is simply refusing to allow the SDGM to proceed to the sleep state.  We do NOT think it is the telematics VIM module - since we already duplicated the problem with the "VIM bypass" solution installed (we reverted that since it also disables the gmc app - but it does not appear that the telematics system is the culprit).  We've replaced the rear heater control module, tested without the wireless charger, and the other modules on CAN Bus 5 - but still something is keeping us awake and removing X2 from SDGM allows sleep to proceed.  We cannot diagnose from OBD since OBD drops off at about the 9volt level in sleep mode and we can't communicate with the vehicle - also we can't trace the SDGM internal packets from the OBD side - we have Autel Ultra.   Any ideas on why disconnecting X2 would allow sleep to proceed appreciated.  This is no longer a repair situation - this vehicie is simply unusable in this condition and NOBODY at GMC Dealer can even understand what it is doing.  This is crazy.  We made these systems too complex and now we're paying the price.

      Did this ever get solved?   I'm chasing 2021 Yukon Denali electrical issues - vehicle will not enter sleep mode - we can disconnect and reconnect the battery and it will sleep - but that's likely because we powered down whatever module doesn't correctly sleep.  once we start/accessory the vehicle and turn off, it will stay at 11.5 amp draw with something keeping the SDGM alive - it appears to be activity on the X2 segment, specifically CAN FD Bus 5 - but we don't know which device and we think we've already isolated all of the devices on that segment - so what keeps the BCM and/or the SDGM alive is unknown.   I don't yet have a packet trace from CAN 5 (and since this Global B we might not get much info from it) - but the vehicle has been down for 8 weeks and previously GMC Dealer was unable to resolve "kills battery" issues with this particular vehicle - so I'm at a loss - it seems to be beyond local repair capabilities - and the number of "telematics keeps vehicle from sleeping" posts indicates this whole architecture has major issues - I hate to say it, but we might have to install a battery cutoff switch on the front grill - one of those red boat switches - to turn off the vehicle.;)  Any pointers appreciated;)  I just bought a CAN FD interface and I'm planning to try Savvycan and Peak Can SW to triage this further.
