Trailblazer Front Differential Oil change. Do it before (Winter) its too late! 

Without your video, I would have never changed the oil in my front differential. Turns out there wasn’t even oil in the differential at all. You my friend just saved me over $800 in repairs!!!!!!!

Hi Nathan. I'd just like to take a moment to thank you for all of the Chevy Trailblazer videos you have made. I just picked up an '06 Trailblazer needing some work and your videos have been of great help in getting me on the right track. I know how much effort it takes to shoot and edit these videos in addition to doing the workon the vehicle. So thanks again for what you have done. I, and I'm sure a lot of folks who don't leave comments, certainly appreciate it.

Best video I've seen on this particular part so far. Just finished mine now, thanks!

Thank you looks easy. Saves a lot of headache down the road.

Thanks for the video from Vancouver, WA. I have a 2002 Oldsmobile Bravada and will take your tips and save me some money on my differential fluid change.

Thanks for putting the great video together. I like the idea of the funnel and tube - will make this job a LOT easier to re-fill the Front Diff. Thanks again!

Very helpful ! I like that your videos are edited well in a way that shows the pertinent info . To the point without the extra bs of other videos. Thumbs up for sure. And, Thank You !

Im scared to do it . but I have to do it cuz my truck needs it really bad. Thanks for the tips

Great job! Clear and concise. Easy to follow and understand your instructions. Thanks. Glad I found this video. Times are tough and she's not pretty but runs good for her age. Gonna give a try when I change my oil today. Thanks again.

Happy Thanksgiving from Houston, Texas!! Good video on that Trailblazer!

I just bought a 2006 Saab 9-7X and I'm going thru it to make sure it lasts a long time. Thanks for the instructions and saving some serious money. Thanks from Connecticut

I like the garden hose over the wheel with the funnel trick! Good video.

Great video! Watching from FL

Always enjoy your tips and tricks. Watching your videos in Florida.

Salute from Boston!

I sure am glad I saw this video when I did. I just crawled under my 06 Envoy to do this job and when I drained the old diff oil only about 4 or 5 ounces came out! Both drain and fill plug were loose too. Thank you sir!

Thank you for this video. I was unaware or ignorant of this need and possible problem. Best to you from Tennessee.👍

As always awesome videos!!!! Im going to check the differential on my explorer today

good job myfriend, thank you.

I like the way you hooked your funnel with a Bungee Cord that was a great idea that I will be useing for now on

Thanks from Brazil, we have a similar here that is called Chevrolet Trailblazer wich mine is a 2018. You're the man!

That was a pretty cool way of doing it definitely deserves a thumbs up 👍

Good video, from Michigan and going to do right away on my Rainier...Thanks

My next saturday project, Thanks!!

Very true this front diff is notorious for leaking not just from the seals. You have to check the fluid at least once a month in the winter. I replaced my seals and it still has a slow leak.

Thanks for the great video. You were absolutely right about differentials always being neglected. I bought mine a few months ago and normally change all fluids but hadn't gotten to the differentials yet. I pulled that drain plug last night and about died.... I was dry. I got just under 1/2 a pint!

Great video. Thank you for sharing

Thanks for the tips change mine this weekend and didn't even think about the front diff thanks

Great video, thank you, take care.

Doing this today. Thanks for the tips!

That hose and funnel truck is Briliant!!!

Southfield Michigan thanks for your videos

Sweet deal I sure do really need to have this done on my 02 Chevy trailblazer LT too and besides for mine I have to have the whole differential replaced because of the bearings do go out too by the Shafts it was easy on the passenger side but the driver side is a whole different story to get done

Thank you from NY. 2003 Trailblazer 183,000 miles. Replaced a lot on this so by the time I'm done it should be like the Johnny Cash song. Pick a Part guys now know me by sight! Lol!

Excellent idea with the 5/8 hose!👍

Thank you, from North Dakota.

Thanks for the Tips! ROCKWOOD Tennessee!

Beautifully!! U are helping me like u have no idea. I got one of those chevy blazer and what you did am going to do it. I got this vehicle for my daughter so she can go to college

I can't believe last time I did this I removed my wheel to get a long funnel in to fill the diff. Thanks a million!! :D

Thanks from LA

Great video full of great ideas I need to change mine that worries me could you cover the leak in depth does anyone make a stop leak for the diff?

"Happy Thanksgiving" from the Great pacific Northwest, Oregon, God bless.

Cheers from Seattle Wa.

Very nice video sr

Thanks for sharing your tips on making this service as painless as possible. I particularly like the tip for using a hose and funnel.

Thank you for your video. I just drained front fluid on my Saab 9-7x (GMT-360) and as suspected fluid was low. Believe my axle seals are losing fluid so cleaned area at the same time. Biggest laugh is I could not owners manual in video at 2:33 that list 2.6 pints at 0.8 liters....Grrrr on idiot that did basic conversion as it should be 1.2 liters of fluid. Thank you again for your post and reminding me to service front diff. Best regards, Mr. P

Awesome tip dont know if I can do that or not I use the pump. Hey all also check your rear diff oil and your transfer case!

I did my front and rear and new seals, it looked pretty OK! 2004 GMC, glad it's done but Amsoil wasn't cheap + oem metal seal. It was nothing like that ^

I would imagine this is the same for the GMC Envoy. Good tip I will change the front diff oil. I was just going to do the rear because the gasket has a some sweating so I may aswell do the front. Northern Ontario Canada. I just retired my 96 Jimmy transition died.

you got a thumbs up

Thanks body from Cali Colombia.

Man that’s probably the noise I hear in ours I thought it was a wheel bearing! Nice .. I’m just gonna change it if it’s noises so be it maybe it will last with the oil 👍🏻

Thumbs up from Westmoreland, NY. East of Syracuse. -5 F today 11-23-18.

I appreciate your video,thanks! By the way did u ever found fix the leak if so how?. Thanks again hello from NYC

Reminds me of the time I drained the oil for a change and there was maybe a quart in the ENGINE!!! Yep, that's right.. it's at 173,000 miles now and still going great.. gonna do the differential soon...

Subbed and thumbs up! From Cabot, AR.

Watching from Boston, I have a saab 9-7x aero 6.0

Make it look easy mine been on since I bought it

Good afternoon friend and I looked at your videos that have been very useful to me, it has made my work easier more than anything, how to do things well beforehand, change the mass, guide me with your video, it was very useful, will you have a video how to remove the differential? it damaged me and I would like your help how to remove it my truck is a 2002 Oldsmobile bravada 4x4 I would appreciate it very much greetings

holy cow I didnt know it has oil Im ging to check mine

Since you have the book what is the recommended mileage change interval Front/rear diff Transfer case Transmission.

Changing mine next weekend front and rear. Did my transfer case yesterday and Damn man the lube looked as bad as what you drained. I need to diff cover before I do the rear. Its so rusty I'm scared to pull it off

P.S. Very helpful tips!

I have an 01 blazer and did this 3 years ago. Had about the same! Mine was greenish yellow. I check mine every out change now! I have had the blazer now for 15 years.

Greetings from "Virginia". Happy Turkey Day, Nathan.

Did that oil stay in into the next year? How did that go? Followup would be great. Even if everything is fine.

When changing my oil I remove 3 of the 4 bolts holding the skid plate, loosen the 4th bolt about half way and swing the plate out of the way. 3:30

Changed mine today. When I drained it the fluid didn't even coat the bottom of the drain pan. I was amazed at how little came out. Transfer case and rear diff were full.

Greatings from Switzerland here! Thanks for the tips, I am looking for a Trailblazer 4.2 LTZ currently. Any more tips of what to check when I buy it? Most I found are ~140k miles.

Good educational vidio Midwest nebraska

I just want to comment about your statement about changing the front differential by removing the fan clutch an shroud and AC compressor and alternator. Removing the radiator was optional just protect it from damage. Also the AC compressor just needs the line mounting brackets disconnected so you don't have to evacuate the freon. I had tried getting 4 or more shops attempt the job but then turn it down because the shop manual has you pull the engine. The RU-vid videos that have you disconnecting the motor mounts to jack the motor up is almost impossible. In every case you have to pull both front CV axles and remove the actuator mounted on the passenger side of the oil pan before pulling the differential. After that with the fan clutch etc removed I just laid the differential on the cross frame and then lifted it out from the front of the car. Replacement went so easy that I forgot to preinsert the rear mounting bolt in the differential an i had to remove it again to put it in place. As for a periodic check of the fluid level you only need to remove the fill plug and insert your finger in the hole to check the level. Here's one more tip for easy topping up, get a tight fitting tube and a small clamp to hold it in place. Cut the tip off the top of the bottle and place the tube on securely and clamp it. You only Ned a couple feet of tubing. Stick the open end of the tubing in the deferential and squeeze the bottle slowly watching the guild until a little drains out from the fill port. Check this every time you change the oil because access is easiest then and you already have everything ready to clean up a spill.

Kerosene pump works good too

Salute from indiana

nice video i save some money and i buy more tools😁i am front Des Moines iowa snow storm the are bad at here

Can the drain and fill both be done on the front diff and transfer case with It on ramps? Or does it need to be level ground when doing the fill? great videos Btw

Can i put diesel in the diff and let it sit for a couple hours and then flush with 75-90 after that?

What's with the skid plate bolts? The two rear ones we're free spinning and had to cut them off. Were the back ends originally welded to the frame? I need to replace them and not sure what to use. Any ideas? Thanks

thank you for the video, very clear , I have question, Front differential in my Trailblazer is leaking, fixing it will cost more than the price of the car LOL, can I leave it without oil if I am not using the 4WD, means I keep the car rear wheel drive? when dose the front differential engage ?

Do you have a video on adjusting outer tie rods and straightening steering wheel and toe of tires? thanks

What about the back bro would love to see please I got 2004 ls trailblazer 4WD

Removing the 18 mm fill plug bolt was a challenge. I took it to PET boys and they ended up rounded the bolt so they did the back filling way. I will need to do that myself this time. Some had suggested to torch it first. Any tips for removing the stubborn, rounded fill plug?
