I was able to get all the tools in order and complete both left and right in under 3 hours thanks to this instruction video, it made my life so much thank you!

excellent video... the only thing I would suggest different is that a person that is inexperienced should keep the nut on the axle when hitting it or use a center punch so that you don't strike it and graze off and damage threads on axle. other than that, again your videos are very detailed and informative. I have recommended them to a few people already.

Thank you I have used several of your videos to fix my Rainer my self and it saves me a lot of money and I am a female

Welp…I’m not an everyday mechanic. I do the basics to my truck. Brakes n rotors, oil changes, tire change n rotation, fixing battery issues, censors…u get the point….but my main point to my comment is that I’ve been fixing my ‘05 Trailblazer on my own to save a few bucks with bigger jobs for the past couple years. Now I can put hub bearings on the list of things I fixed/changed myself 👍🏽. This vid was very clear n straight to the friggin point to help me continue to do so n save a dollar or two. So thank u! Highly appreciated n keep up the good work.

Btw….Liked n followed.

This was the most ambitious repair I have ever tried on my 2005 Trailblazer and I couldn't have done it without your video. You made every step of the repair work clear and concise. Another mechanic working at the public garage I was using gave the advice of keeping the nut on the axle prior to hitting it with the hammer which was good advice as it took more than a dozen blows on each side to loosen the axle from the wheel hub.

Can't thank you enough for the video. I was able to replace the Wheel Bearings and install new rotors and pads on my moms 06 Trailblazer... Cheers

[rudwn]

Thank you for posting this video! I just did this same job on my 02 trailblazer ls but the only difference I came across is the axle nut socket was a 36mm not a 35mm

[BIGTAGGART]

So I have a bad wheel bearing so they sell just the whole hub assembly so no need to press out and in a new bearing??

[skyhigh]

Watched the video on replacing the hubs, very helpful, Although, I did encounter a problem I did not expect. Recently replace my tires, evidently, the person who installed my tires rounded off one of the lug nuts so badly that the 19MM socket would not fit the lug. All the lugs were so tight that I had to use a breaker bar. Thanks, it was a hard job for a guy in his 70's. The passenger side hub was almost rust welded onto the spindle. A little liquid wrench and a three-pound hammer I finally got the hub off. But your video did HELP a lot.

[MBrain]

This guys videos are top notch. He has helped alot. Yes he made a mistake. It is a 36mm. Other than that all his stuff is spot on.

Awesome video. I just did my wife's 2006 Trailblazer and this was a great help to me as I had never done one of these before. Unfortunately, you were out of stock on the hub assembly that I needed but I will make a purchase from you in the future as my way of saying thank you.
BTW... I am the one guy who needed to hit the assembly more than one time to get it off.

[brianburkovich]

Thanks 1A Auto for the video tutorial. Followed it step by step and this non-mechanic changed out the part with no issues. Just a note though.... perhaps you could put a mention at the beginning of the video that if you're going to have your vehicle up on jack stands to loosen the Hub Nut before raising the vehicle.

Aside from that I owe you guys. This video showed me that it's not too complicated for the novice. It gave me the confidence to tackle it on my own. Sorry to say that I needed it done quick so I got my parts from Napa. You also showed me Brake Shoe/Caliper replacement. You guys would dominate the internet if you had tutorials on all makes and models for all parts that didn't need "special" tools/ lifts or other gear.

You guys are Your videos have saved me hundreds if not thousands of dollars at this point!!!!

I haven't read the rest of the comments so if someone has mentioned this, oh well. I am amazed that you used a metal hammer on a threaded shaft. That's a good way to damage the threads. I use a plastic dead blow or if I don't have one I will put the nut back on almost all the way and hit it (not the safest way but better than risking naked threads).

[skyhigh]

I just wanted to thank you for all the information you provide, it has saved me literally thousands of dollars. I purchased a 04 Trailblazer about 1 year ago, this SUV has been nothing but trouble from day one. I have literally rebuilt the car front to back. It seems that my wife (who now drives it) tells me daily there is another caution light on, check engine, check garages etc. But it wasn't until I had a doctor appointment I notice that the car had a terrible grinding noise coming from the front of the car. Her solution to the problem was turning the radio on loud enough to drown out the noise. it turned out to be the passenger side wheel bearing hub. It was so worn out I had to beat it off with a 3-pound hammer.

[andrewgilbreath]

Thanks for the video, I do most of my own mechanic work when I can but wasn't sure if I wanted to tackle this project I think I will and save myself the $485 the shop wanted to do the wheel bearing, I just did brakes a few months ago to bad I didn't realize the bearing was going bad could have saved myself some time.

nice video. he should specify in the tool list at the beginning that you need a DEEP socket 35mm, that axel sticks out a lot.

[RingZero]

I would clean all the assemblies thorougly including the knuckle flange where the hub sits on and apply some anti-sieze on all metal to metal contacts.

[AAuto]

On the 2WD model you wouldn't have them. The Trailblazer shown in the video is a 4WD model, and that nut helps to secure the axle into the hub. Hope this helps you out.

Just got done doing this in the driveway, in the rain. I had the new part on hand and was planning on doing it on Saturday with better weather, but the wife called me and said it had started a wobble in the neighborhood, could I get it done tonight so she could get to work in the morning. Came here to double check removing the old assembly, mine was a little tight coming out. I had all three bolts out, but wanted to see if there was a clip or bracket holding it back. I wanted to make sure I hadn’t missed anything, and make sure it really was just stuck. The dead blow hammer didn’t get it done, but the 3 lb sledge got it loose. Buttoned it back up, did a road test and she can get to work in the morning. Thanks for the video.
