This dude is flat good. He does a great job of explaining a complicated procedure. I highly recommend his video. He is definitely in the top tier of guys doing this stuff. Thanks for all you do!!!!!!

[@NiXFiX]

Thanks Dan!

[@Missnewgen]

Super awesome video thank you very much for all your detailed instructions and visuals and for including refill of the fluids. People tend to skip over some of the smallest steps and things get broken and destroyed.

[@lawrencebray9514]

I did this 2years ago. While I was there I replaced the starter and ALL the seals. You should also replace the o ring on the oil pump on a LS motor. This video is awesome!! Made the difference for me. Thanks

[@koanytone]

You are a life saver! I wish every video was as detailed as this one. I watched one and it looked so easy then come to find out it was only a 2 wheel drive. So needless to say I’m already knee deep into then your video came up and now I’m going step by step as you did and feel way more confident and understanding of what I got in store for myself. Much appreciated and thank you for making and sharing this more than helpful video!

[@andreshenriquez3087]

Hi, where I can find that video? Thank you

[@flagcityparts]

I've used your video as a means to remove every known 5.3/6.0 found in the you pick yard because nobody wants to mess with pulling them

[@Supercharged111]

Good video. It's convinced me to just live with the drips! 🤣

[@chrisbourgeois175]

This Job is in my future! I had a local Garage try and cure my oil leak, they found it was the oil pan gasket. So I dropped it off on Wednesday night, and they changed the oil pan gasket. they didn't cure the leak, so the changed the gasket AGAIN! Friday afternoon, they called me and told me to come get the truck. They also told me that I owed them NOTHING for the job, as they were unable to cure the leak, and suggested that I call the dealer and have them look at it. The reason I brought it to them, was I didn't WANT to do the job... but now I guess I WILL be doing this job. And instead of just the gasket, I will be replacing the whole oil pan! Thanks for the Video!

Great video gives me more reassurance that I can do it myself! Great job my driend

[@stevekluze3094]

Thank You for doing this video, it really helps out.

[@jamesb1221222]

Just picked up an 07 envoy the other day, has 5.3 with 150k. Bought it from a junkyard in VA for a good deal, no rust. DOD lifters make a ton of noise which is why no one bought it (probably thought it was a rod knock). Truck does lose oil pressure after a few minutes of running, so I'm gonna replace the oil pump with a hv pump, pickup o rings and delete DOD while i'm in there. Gonna be fun...

[@JayJones540]

Cross member and AC compressor tip helped a lot! Btw I didn't even have to remove the strut or links I just removed the spindle itself instead!

[@devastator2773]

Thanks for the video. Helped out a lot just finished this job today!

Great vid man

[@daveharness70]

My diff and actuator housing were really stuck on my oil pan. I broke the actuator back plate that fits into the oil pan when trying to remove! I was doing it after pulling the engine though...i likely should have left the entire housing together for added rigidity. Im about ready to junk this 06 trailblazer...such a pain to work on! Exhaust valves locked up..so need head redone. But want to check bottom of engine before rebuilding head...have to pull oil pan to get front cover off to get to oil pump and timing chain!

[@myrondel]

BTW thank you for an excellent video.

[@Criscoluv]

Nice job with the video!!!!!

[@Criscoluv]

Your a life saver I doing this job now. I am changing the o ring for oil pump but I also saw the oil filter housing on the inside. Question dose anyone know if there is a o ring for the oil filter housing??

[@amandalynn5058]

Great video! I have the exact same problem with my 5.3 Envoy and was guessing this is the problem. Mine will lose pressure completely at idle. I'm temporarily getting by with adding an extra 2qts of oil. Read on another forum that with the extra oil if it works, very likely the seal. My question is, do you know if the crankshaft is low enough to hit my oil level? Don't want to whip my oil into salad dressing, know what I mean. Is the pickup tube seal lower than the bottom of the crankshaft. I need to do this seal change but it will take a bit of time. I've checked my oil several times after approx 50 mile runs and don't notice any whipping/foaming in the oil so I think I'm OK. I run synthetic so less foaming and it is a V8 so low RPM......I'm thinking I'm safe for awhile. Thoughts?

[@scottbeattie6032]

I'm following the procedure and making progress. One question on the AC compressor bolts. I have the bottom 2 out and I found one of the top ones to loosen (frontmost; can be seen through the wheel well). I can barely even see the rearmost top bolt. How were you able to loosen it? Did you have to remove some other stuff first?

[@angelf9800]

Question Do I have to remove all this out if I just wanted to replace the front timing cover, I broke off 3 of my water pump bolts and I just figured I can just get a used cover from the junkyard and installed it

[@daveerrington5166]

Did you do the oil pick up tube oring?Great video

[@antonioaguilar3850]

I have a 04 envoy xuv 5.3 litre what want to know is how did you remove the cross member to lower the oil pan and where did you pickup the engine from to have that 2inch clearance

[@daveerrington5166]

This would be a good way to remove and replace seals in the front diff as well

[@edwardhorton7029]

Did i miss the replacement of silicone or seal of the diff and actuator on pass side into the oil pan?

[@devastator2773]

I ended up changing my gasket on my 4WD envoy and I still got a leak :/ I think i might have scraped some RTV off throwing it back up there. Sucks its a big job to redo.

[@beefwellington9926]

What size bolt is the inner drive shaft thank you brother would have never got this far without this video I'll like and subscribe

[@NiXFiX]

Metric. M6. Slide hammer is the way to do it by the book. You could make a homemade slide hammer with M6 threaded rod. I just used a long M6 bolt with a fender washer and whacked it from the backside with a hammer and a chisel.

[@scottbeattie6032]

I found that I couldn't get a M6-1.0 to work. It would only go on a few threads. But I did find that a 1/4" bolt worked perfectly for me; it threaded as much as I needed it to. I also rented a slide hammer and Pitman arm puller from AZ (both have the same bolt/thread size), and fortunately I had a really wide washer that fit the Pitman arm gap just perfectly. I think it came out on the first or maybe second pull.

[@Todhwart]

Hey man thx for the vid! I have an 03 TB 4.2 and have to replace both cv axles.. as i pulled out the one off the diff there came out a lot of oil .. is there any oil in the diff ?? Or is the inner sealingring done and its leaking out from the engine oil pan ????? 😱 The outer one is also leaking - i want to replace it after i got out the parts of the broken 4wd actuator housing on the other side 🤦‍♂️😠 Greets from Germany 🙋‍♂️

[@NiXFiX]

There is oil in the differential. You probably should''ve drained it first. I re-fill the differential at 32:32 of the video.

[@krazobuildz7567]

Is the oil filter tubes in the oil pan press fit ???I’m trying find something online but nothing so far

[@blackknife1]

Great video bud! How many miles did you have when it started leaking? I have 216,000 on my 2009. My mechanic suspects the oil pan, and possibly the rear main. I'm wondering if I bought the pan for nothing, and it's just the gasket. They said it had some rot, but it's cast, and cast doesn't rot as far as I know. Oh well, I'll have a new pan. Thanks again!

[@NiXFiX]

Highly doubt your oil pan rotted out. It could crack, but not rot.

[@daveerrington5166]

I hope to never have to do this repair. Thats a crazy amount of work

[@NiXFiX]

You aren't kidding!

[@markdixon392]

Great information... thanks for posting. How long did the process take you?

[@NiXFiX]

Thanks! 10 hours or so.

[@ronnydevlin6329]

dropping the rack and pinion and putting it back up like you show i did not take nothing loose but to mounting bolts. after getting done it all seemed right to me. i drove a few miles watching the oil pressure. and all of a sudden it seemed like the toe in was out and the stabilitrak came on. felt real bad to drive so gave a quick look and drove 1/4 mile home if that. now steering wheel is turned about 30 deg. and the play in the wheel comes and goes. If turn off stabilitrak this still happens but does not feel like it is trying to correct. Put envoy back and stands and all seems tight. Any suggestions?

[@ronnydevlin6329]

Also find nothing wrong with any sensors at wheel or front of motor where took apart to change oil pump.

[@ZareefHuq]

I may have to do this because a small rock fell into the windage tray from the valley cover area. Extremely unlucky. How long did this job take you?

[@pilover7347]

To access the connecting rods do you remove the plate underneath the oil pan?

[@NiXFiX]

Yes

[@xXNitemareXx]

Your video came up for my 3.4L 6cyl FWD 2006 Chevy Equinox. I'm trying to repair or replace anything I can on my own that's easy to moderate in skill level, and I THOUGHT dropping the oil pan would be a breeze! Jesus, lord have mercy! This is insanity for a damn oil pan. Another video I watched was not as labor intensive, however, your video seems to align more with what my Chilton's manual says needs to be done. This is one I'll leave to the pros at my local mechanic shop! More and more, I'm starting to hate this Chevy based on how difficult simple things are. Just to check the ATF is insane. Who the heck decided to put the dipstick UNDER the engine and require the entire car to be lifted just to get to it? WHY? (Completely rhetorical, not looking for answers. I know why. $$$$)

[@Missnewgen]

Absolutely hun I feel you. I've been a mechanic for over a decade and this is f****** stupid. I've worked at GM proving grounds with the engineers who designed this s***. If I still work today I would slap somebody. Couldn't have picked a stupider design for a f****** oil pan. Anywho this was a great video to show us how to do it he even went over the fluids.

Even though you have to do all this work is still the best SUV of its time as far as dependability. Ford Explorer V6 terrible Timing chain problem also their transmission.

[@NiXFiX]

I no longer have this vehicle, but yes. Great platform. Body on frame (decent towing capacity) and inexpensive to maintain.

[@royfernandez3219]

Can I take out the 4wd actuator without taking the cv axle out? & also is it really necessary to take out the inner axle ?

[@kipholder8577]

Yes

[@eltoro3911]

How did you remove the transfer case? Having problems pulling it out on the drivers side

[@NiXFiX]

The transfer case stayed in. I think you mean the front differential. I just moved it to the side as far as it would go to clear the oil pan. If you want to remove it completely, most people remove the battery, battery tray, the alternator, and the AC compressor (on the 6 cylinder) and pull the differential up and out.

[@myrondel]

LOL, definitely not for an inexperienced backyard mechanic. I need to address a low o/p condition and considering how involved this is I'm thinking I may as well pull the engine and pop in a rebuilt engine. I knew it was going to suck when I saw the drive shaft through the oilpan.

[@150db8]

Thanks for the video. Just removed the motor from my 05 trailblazer with the 4.2 I6....question How familiar are you with these... Particularly the GM360 platform?

[@NiXFiX]

[@adamhouk3373]

I am getting ready to tackle this in a few minutes. Do you have to remove the inner shaft from oil pan to lower it or canit still be in oil pan when lowered and change shaft to new oil pan before instal

[@NiXFiX]

All steps are required. The inner shaft connects to the front differential.

[@adamhouk3373]

@@NiXFiX I know it is all connected if you remove front diff can you lower the oil pan with the inner shaft and remove to put in ne pan or does inner shaft have to come out of oil pan before lowering

[@NiXFiX]

@@adamhouk3373 if you remove the front differential completely out of the car, then yes, you could lower the pan with the inner (intermediate shaft) still in pan. It is far less work, however, to rest the differential to the side (as shown in the video) and pull the inner shaft. Look up the process to remove the differential from the vehicle and you'll see what I mean.

Ran across your video. I have removed all four differential bolts and I cannot get the differential out of the oil pan.

[@NiXFiX]

Sorry for the delay in response. Did you end up getting it off? It has been awhile since I did this job and would have to re-watch my video to see if I can spot why you can't get yours off. Did you pull the inner/intermediate shaft out first?

[@daveerrington5166]

Why would my differential cover have oil on it? I'm trying to figure out if I have a problem.

[@NiXFiX]

What do you mean by cover? Do you mean the skid plate? In general, any oil that you can see anywhere on your vehicle means there is a problem.

[@voidisyinyangvoidisyinyang885]

@@NiXFiX if I start using Marvel Mystery Oil and it starts clearing out junk into the oil pan - would that oil pan REALLY have to be removed and cleaned out? Or is there enough depth in the pan to let the gunk just hang out there. haha. Also how come you did not regrease the passenger CV axle spline or diff spline? I read that should be done on this set up. Nevertheless - a VERY impressive job - you talked through that very smoothly and did an amazing job - removing that cross beam made a huge difference. I know hardly literally nothing about doing mechanics but I've been doing a crash course just to figure out what kind of repairs to expect on an 04 trailblazer. thanks

[@therealRobFlynn]

Great video, is the leak gone? This looks exactly like the leak from my 9-7x. Man that's a lot of work to replace that gasket

[@gabeh.5061]

Wouldn’t it be easier to just drop the pan and then pull the shaft out ?

[@NiXFiX]

No. As I recall, the shaft goes a distance into the front differential. To get the differential out or the oil pan down, it has to come out.
