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

[@gregbruns8442]

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.

[@FixingWithPassion]

Nice! TB's are great and are still going today!

[@emaambition9378]

Highly appreciate it. I used to think it was in the rear end. I can’t wait to change it. God bless you and your family

[@FixingWithPassion]

Yea i'm checking it agaion

[@emaambition9378]

If you don’t mind. did you snug the bolts or over tight them?

[@thatoneguy4412]

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!

[@FixingWithPassion]

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 !

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.

My power steerings stiff at low rpms too, also an 02. Replaced all the ps lines cause they were viciously corroded. I'm trying to diagnose, will be changing a couple things this weekend so if I figure out why the ps has been stiff I'll let you know. Is your 4wd service light on? Mine is and I haven't figured out yet if that's related to the ps issue at all or not

I just got a 2005 trailblazer. Had all fluids changed except just added antifreeze. I was told the front differential was bone dry so it was good I had it done. An hour later the front end had a huge puddle from a leak and almost all the fluid was leaked out. I assume it's the front differential but I saw antifreeze in the leak im pretty sure. So I went straight home instead of going back to wingman oil change.

Nice!!!

[@janesays4234]

@@FixingWithPassion but im asking. What do you think it is? Do I need to ask the shop?

[@ednorton47]

They used a liquid seal at the factory. Sometimes the machine that applied this sealant at the factory ran out of fluid. My differential was leaking from Day 1 until it finally broke and had to be replaced. GM would never admit the flaw.

Hmmm .. There is a Imperial-SAE/Metric conversion error at t=2:19, 2.6 Pints = 1.23 Liters (not 0.8L) Therefore - you should put 1.3 Quarts in the Front Differential (2.6 pints is more than 1 quart, which is typically how 75w90 is sold / 32 oz./0.946 liter) here in the gold ole USofA that never wants to convert to metric.......)

Extra is good if you have a small leak. Kind like having a x amount of bank overdraft for safety.

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?

[@jumpin386]

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 KZbin 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.

[@christopherzube551]

You could go to any junkyard and look for one. If you are good at do it yourself work then you would save quite some good money changing it out yourself. But if you don't really need it then you can disconnect the front cv axles from the hub and you won't have the service 4wd light on. Take the tire off and and remove brake caliper and rotor, remove axle nut, disconnect upper and lower ball joint, then remove rubber boot in cv axle and take out the first half where the knuckle is. You'll know because it has a crap ton of grease. Leave the other half that is connected to the differential and actuator .then put it all back together. As long as those halves stay in place then you won't have the light on your dash. If you don't ever plan on using the 4wd again than you can buy a pcm for years 2002-2005 for just the rwd and get rid of the 4wd completely.
