I was just thinking the same. And still no vedios showing it that way which is easier. I've like a dumb a$$ have bought and run the 2x4s batteries thinking it was upgraded to take it since the 8s moniker was put on it. At the factory they tightened a spur screw to tight that broke the screw hole at the bottom and it got in with the gears and stripped all but 5 combined. Took it too the LHS and also noticed it had a crack there all the way through the gear. That let me know it came with bad QC. Now trying to find what is binding somewhere. Thought I got all the teeth out but seems one or a couple stuck around. Trying to find it because the xmaxx will roll backwards and sometimes forward but also at some point it comes to a stop when let off the throttle it will catch and rock. If pushed in reverse will roll but pull it forward and sometimes it catches and all tires stop. I'm dumbfounded. Checked and cleaned rear differential and filled, front differential cleaned and filled and putting better grease on the diffs. Guess in going to have to get to the center diff myself and check if any teeth got in there. Sometimes catches sometimes not. Will drive but dont want to damage anything else.
Also funny, the grease I use is the same grease my Grandfather used on just about everything and still using the tub he got before he passed in 94. Master Pro high temp disc brake and bearing grease. Have used it on all rcs I have redone the front and rear diffe and it works great. And its red like the one you used.
I wish I knew at the time to just take off the rear bulkhead! Sorry I don't have a video on that yet. It sounds like your problem is definitely in the center diff! I love the story on the grease! Thats great!
Welp, looks like there are 2 of us out there that did this job the same way. I was rebuilding a used xmaxx and needed to do more than just repack the center diff, but ended up going about it the same way. I have a CEN Reeper that is a massive pain to get to the front and rear diffs, so i wasn't too worried as i went along.
Thanks for actually showing us what you did, so many videos skip over things and does not cover everything… You did, thanks! Did have one question, can you take the input shaft gear cover of without removing the bulkhead? It would be the cover that comes off next after removing the kush drive, 4 bolts cover, Like if you wanted to inspect the gear of the center diff that runs off the Kush.
Thanks im glad it helped! Honestly i wouldn't feel good giving you advice on that, i havent taken apart my xmaxx since this video! But from what i know the only way to access the center diff completely is to remove the bulk head but if you just want to inspect the gear i think you can take the small cover plate off of it to get access
i hope you got the puzzle back together :)). i think if i start something like this in the end i will have enough remainig parts to build another x maxx :)))
Yes I do, I use marine grease just to help with any water that might seep in, but you can use any grease, one of my trucks I just used regular axle grease. The manufacturers usually just put a tiny bit in there so it definitely helps to give them a good amount of grease. If you go so far to pull apart your truck to grease the diffs you might as well pull them out and change the diff fluid, if you need help with that I have a video on my channel about it and it really does help the performance of the truck thanks brother!
Just got the 20 million diff fluid in the mail yesterday but after watching this I’m super skeptical now about getting in to all that. There has to be a easier way to get access to the center diff I’m hoping 🤞
I really dont think there is! I tried to make it as simple as possible and still had to do all this!! Some one told me if you search 6s xmaxx upgraded to 8s there Should be another video on how to get to that diff!
When i did this video i didnt know that you can just remove the rear bulk head in one piece so alot of this video is wrong, just take your time and remove the entire rear bulkhead in one piece, sorry for the confusion!
Right? I’m watching it like, bro, you’re making way more work for yourself than needed. But I still watched the whole thing to see what not to do. lol.
Wow that is a serious looking job. Being the total noob I am think I will do the front and rear first. Then go knee deep after I gain some experience lol. But I guess this is all part of the process in learning this hobby. Thanks happy new year
@@craigsrccrc4128 haha i know right 😂took me a long time even to figure out it has a center diff😝manual doesn't say a thing.keep it up mate! Keep bashing 💪💯🔥
You’ve made it way to hard. You just need to remove the rear bulk head as one assembly. Then you can get at the diff much easier. You definitely learned something. Good luck getting it back together.
@Durham Reality you're right! I'm wrong, so sorry I'm such an idiot! Everyone studies the manual! I guess I should never get a new RC that I'm unfamiliar with
What a pain in the ass .... haha. One of the best - how to do videos! I dont know the word in english, but you are using some bad words :-).... i see me in my hobbyroom and doing the same every time. Go on, graet video. Not perfect - but good for me and entertaining!
It really is a pain! Everything else on the truck is pretty easy but the center diff is a pain, my arrmas are also very easy to work on and I love that!
X-Maxx is the easiest RC 4x4 car to work on that I've ever had. Of course 2wd's are easier LOL. X-Maxx is big and more room to get to things. Large bolts etc...
The full instructions aren't in the manual but it does show which screws are holding the rear end on. I always have to keep looking back at the pics. Thanks for the video!
Just fyi you can remove the rear bulkhead in one piece! I didnt know this when i made this vid so just be aware! Thanks

This is exactly why I got into rc- ing. I love working on them. This is a lot of fun for me

Brother,you did well. That's called " hands on training,and it was all you brother. Again,way to go. Keep it up brother
Well thanks that's nice considering I did it completely wrong!😄

The xmaxx rabbit hole 😂
Good video thought, live and learn
i hope you got the puzzle back together :)). i think if i start something like this in the end i will have enough remainig parts to build another x maxx :)))
Haha I did!, I thought the same would happen to me but I got it all back together!!
Keep a good hobby shop’s number handy
Do you recommend using GREASE for all the diff gears & center gears .thanks
Yes I do, I use marine grease just to help with any water that might seep in, but you can use any grease, one of my trucks I just used regular axle grease. The manufacturers usually just put a tiny bit in there so it definitely helps to give them a good amount of grease.

This is old now but grab the exploded diagrams off traxxas site, shows where every bolt goes and sizes.
It is possible ear wax for center differential
Lots of people use wax earplugs
that’s one intensive job.
Theres no spider gears in the diff?i thought there was?

This time a very easy jib the xmaxx splits apart in three pieces the rear ulk head it's under that 1 hour tops if you don't know what your doing
Mean f150 is right, I did it the hard way! There is a much easier way to do it, just remove the entire rear bulk head
Hello I’ve just done this for the first time and found your video what a pain in the ass hahahaha 😀👍🏻
When i did this video i didnt know that you can just remove the rear bulk head in one piece so alot of this video is wrong, just take your time and remove the entire rear bulkhead in one piece, sorry for the confusion!
you can take the whole rear bulkhead off as one piece dude

@@HughsReviews same,lol
Good video. Never been that deep into my xmaxx
Awesome video! Showed me exactly what not to do. lol.
Hello Très bonne vidéo !!!! Merci
Thank you!
Wow that is a serious looking job. Being the total noob I am think I will do the front and rear first. Then go knee deep after I gain some experience lol. But I guess this is all part of the process in learning this hobby. Thanks happy new year
It takes awhile to get comfortable with them but you'll get it!
Well done mate
The Traxxas online manual will show you how to remove the bulkheads. Your making way more work of this than necessary.
Yea i didnt realize that till later, i couldnt find any info on taking it apart so i just made it happen.
My center differential is peeing the rat just slip does that mean I need a new one?
Way too much grease in the diff case. I did that and it seeps out the bottom of the diff case.
Really? Thats wierd mine hasnt done that
thanks for this video :)
Your welcome! I hope it helped
Look up the video: X-Maxx 8S Power-Up Conversion |traxxas they show exactly how its done 👍
Thank you! I couldnt find a video for help anywhere!
@@craigsrccrc4128 haha i know right 😂took me a long time even to figure out it has a center diff😝manual doesn't say a thing.keep it up mate! Keep bashing 💪💯🔥
I'll look for that video too. Thanks

Thats what I've been told, i didnt know you could do that
@@craigsrccrc4128 Traxxas literally spent millions of dollars on advertising that very thing... Modular Disassembly. It's even in the manual.
@Durham Reality you're right! I'm wrong, so sorry I'm such an idiot! Everyone studies the manual! I guess I should never get a new RC that I'm unfamiliar with

Thank you! Yes there is an easier way I just didn't know that at the time
WOW!! what a messy pain in the @ss lol. My Teknos are way easier. In fact the center diff is the easiest of all 3. Great video 👍
It really is a pain! Everything else on the truck is pretty easy but the center diff is a pain, my arrmas are also very easy to work on and I love that!
This looks like a nightmare... I have this grinding noise and no power to the four tires...oh jeez
Ou t is a kind of a pain but I learned alot about my truck
X-Maxx is the easiest RC 4x4 car to work on that I've ever had. Of course 2wd's are easier LOL. X-Maxx is big and more room to get to things. Large bolts etc...
Thanks! Good advice
kraton 6s
I did mine just now and I did not have to take the motor lose just three wires to it I pulled a fan away from it but yes the pain
Glad you found a better way!! It is definatly a pain!!😁
You might won’t to clean it
Low on oil lol
Not to be funny but couldn't you have just looked at the manual?
It's not in the manual! That was the problem!
@@craigsrccrc4128 I'm glad you did this video then because I need to do mine as well. Thanks a lot and happy bashing.
The full instructions aren't in the manual but it does show which screws are holding the rear end on. I always have to keep looking back at the pics. Thanks for the video!
