Diffs are NOTORIOUS for Failing in Bashers!!! | Arrma Notorious Differential Rebuild

I mentioned in my bashing video with the Arrma Notorious, that I thought the truck would perform better with some different weight oils in the diffs. I decided to make a video covering the steps it takes to change the fluid in these 1/8th scale Arrma Diffs for anyone wanting to do this as well.

Also a good thin to do is if you repair diffs or replace, keep all good parts and eventually you will have a complete backup diff made from the good parts of others or use the spare parts in present diff if worn and need replacing. Especially the diff pins that hold the cup for the dogbone in the diff as the do like to break. When a part goes out or breaks, keep all that is good left from the item. Ittl save money when you really need it or keep you from cutting a session short.

Bought a arrma notorious about a week ago and you made it look really simple! Thank you!

[@FullThrottleRC]

Thanks! It's a pretty simple process surprisingly!

[@refugiopina3402]

I'll be taking my notorious apart this weekend. Definitely going to use this video as a guide

[@tonysmith7989]

I know this is an old video, but in Arrma 6s vehicles just remember when taking the diffs out, if looking at the rear, the gear is on the left, when look at front diff it also has the gear on the left. Unless you build from a slider from someone else and add electronics and transmitter. It ran great till a Cadillac aimed at it and ran over it by a curb. Saving grace was her front and rear tire ran over the Typhon from tower to tower and the space between the shock towers kept her tire off all electronics. 😳 I took it all apart to check everything. Had to straighten front shock tower, straighten a lower hinge pin and replace broken screw with tons of spares I keep Incase. Not 1 cent spent on repair. But I did check the front diff and cleaned it up and replaced it. Mind you I have work on several Arrma 6s vehicles and know how they're built. So took it out and a soon as I hit the throttle I stayed in one spot with wheels spinning in opposite direction. I knew I put it in correctly as I know how they go and always keep manual beside me Incase. Obviously when I bought it as a slider the previous owner had the diffs in facing right. So as long as you put them the same direction even if in backwards all I had to do was reverse the motor spin and it ran great. Did however correct everything the next time I did an inspection and diff work. I laughed my ass off in bewilderment watching it sit and try to move sideways. 🤣🤣🤣

[@FullThrottleRC]

I have also put diffs in the wrong way before and had the front and rear axles working against each other 🥴🥴

Great Video. Did it today for the first time.

Thank You!

First I really enjoy your videos. I bought one of these trucks and at first, I didn’t know they came with 100 K in the center, and 30 K in the front ,back. I took it out of box ran the truck down the dirt road, and the center disc exploded. I paid around $600. I enjoy my Arrma trucks but it’s no way Arrma knew this would work. I installed 60k front and 30k 5:27 back and 500k center. 5:27 Thanks Bobby

[@FullThrottleRC]

Thank you so much! The trucks definitely perform a bit better with some heavier weight fluid in the front and rear diffs. Adding thicker in the center I felt helped me feel like I wasn't losing any power. Good luck!

[@bobbyhaltiwanger5102]

Yes Sir The 30/500/60 is in the truck. So its time to see what going to having nothing but fun times I hope. LOL Thanks for making the video too. Made the job a lot better. I may have time today to see what she does. Thanks Bobby SC

[@FullThrottleRC]

Awesome!! Happy Bashing!

[@norcalrc]

Nice maintaince session. Rarely do you see anyone do their diffs until they are broken. Such a shame when Arrma made them so accessible.

[@FullThrottleRC]

I was actually surprised at how easy it was to get out. I made the video thinking it would be way harder to get the diffs out

[@norcalrc]

FullThrottleRC Arrma has really seemed to engineer their products to be maintaince friendly. Especially the 3s & 4s lines

[@mr.h.5205]

Very Good 👍

[@FullThrottleRC]

Thank you!

[@dr6638]

I just did my Armma Notorious 6s. My center differential melted the housing. Guess it must of gotten pretty warm in there. Overall took sometime since it was my my first time. Used 100k on the center differential. Works and runs nice now. Thanks for the video. Next up LOSI repair😃

[@FullThrottleRC]

Thanks! Glad my videos could help! The only losi I have is the LMT and I really haven't had any problems with it to need any repairs 😂😂

Man you made that look so easy. Just got mine , this will be my next project. It does look intimidating. You took all that away. Thank you I'm not sure about diff fluid. Let me know how you're diff combo worked for you please.

[@FullThrottleRC]

I've been really liking the change. You can see some of my latest videos with the truck on my channel if you want to see how it performs yourself

So glad differentials are easy on these. Traxxas Slash 4x4 is a nightmare

[@FullThrottleRC]

The Traxxas 4x4 diffs are pretty rough to get to, I used to have a Stampede. These are a lot easier to work on.

[@freddieparrydrums]

@@FullThrottleRC When I first took my Slash apart that was the first work I’ve ever done. I thought it would be easy ended up losing screws 😂 I learnt from my mistakes 👍

[@tbonerchobbies8678]

Great video is that body for the notorious? Or is it listed for something else

[@FullThrottleRC]

Thanks! Its actually not made for the Notorious. Its intended to be a trail truck body, I just cut it to make it fit.

[@bassyguitar]

may have just given me the drive to tear apart my kraton 6s and service those diffs.. lol thanks!

[@FullThrottleRC]

Awesome! Turns out it was even easier than I thought!

[@LetsGoitsBrandon]

I changed the diff fluid in all 3 on mine and bashed it pretty hard through an open field. Center diff basically melted and exploded on me. Need to find something a little more durable than the plastic one to replace it with. Any updates on how the fluid setup is working out and holding up on this truck?

[@FullThrottleRC]

I haven't had any trouble with mine since changing out the fluids, I'm actually loving it! I find the truck is more responsive especially in the air. If you check out some of my recent videos you can see for yourself how it performs.

[@paulcooper7162]

Hi sorry to hear this about your diffs,mine. just did same thing,center diff burnt out how do we fix this,the outer is melted also

[@bobbyhaltiwanger5102]

Truck come with 10/100/10, and low on oil too. Ran the truck twice and yeah you know what having. I have a new Notorious sent to me. It's out of the box and I'm changing the oil to 30/500/60.

[@FullThrottleRC]

Yea I feel like the truck reacts a lot better with thicker oil especially in the center and rear diff. The front is only noticeable if you can keep the front tires on the ground haha

[@bobmr.h2603]

30-500,000-30 Change oil to 60. Front and back .Guess who has tried locking the center differential ? Thanks Bobby

[@pipnmaz]

Great video sir, I'm considering tackling my Arrma Outcast 6s diffs which are identical to your Notorious so this was a great help and motivation for me to "Get wrenching" on mine. I was feeling a little intimidated about starting this job until I saw your video and now I feel ready to go. Just wondered if you have any video of this vehicle running since the diff fluid change or any update on your feeling with the new diff fluid - any changes you would make to the fluid you chose? I would like to try 500k centre, 50k front and 20k rear but find the brand of oil at my regular shop only goes up to 300k. I'm not sure if I should go with 300k or order elsewhere to get 500k while I'm doing this job. Thanks again.

[@FullThrottleRC]

I did post a running video a few weeks ago since changing the diff fluids. I'm really happy with how its set up now. The truck handles great and I have good control in the air as well. Thanks and good luck!

[@magosselin700R]

Same feeling for me! Thanks for the video

[@NeighberhoodRC]

I change my center diff to a “Third Version 50t Differential Spool Locker Set” perform better wheelies with it don’t have to keep buying diff fluid for center , I run 80,000k diff oil in front and rear differential

[@FullThrottleRC]

I'm gonna have to look into that! Just put a fresh set of tires on my Notorious hoping to get back out soon

[@fredbloggs7345]

Brought brand new notorious couple days ago. On my second day my centre diff blew up.not sure whot to do now.any advice would be appreciated .thanks

[@FullThrottleRC]

I've never had an issue of the diffs blowing up in this truck. I've dealt with some worn out though. I've seen a few people talk about the EXB diffs. You could try one of those when you rebuild it.

[@rotorballs3962]

Same with mine 7 months ago, I finally replaced it today after finding out that they didn't have the screws tightened properly. Fluid leaked and ran it essentially dry. Housing was melted on mine so I just bought a whole new one off of jennysrc.

[@FullThrottleRC]

I would go with 100k minimum in the center diff.

I have watched every video from 6 weeks ago to now

[@aaronpeters1770]

So i only have one ear and its less than 50%hearing..so i gotta go on sight and feel mostly. I thnk front diff is broken. How can i rotate the tires to see if its broke or if rear or center is broke? Gonna need all help i can get bro, plz

[@FullThrottleRC]

I'm not sure if the diff would be broken. Maybe the oil is worn and needs to be replaced. Try holding one wheel while trying to spin the opposite one, it should spin but if it spins too easily you may need to replace the diff fluid. Do that for front and rear. The center is so easy to pull out, I'd probably just remove it to check, but you could do the same thing by locking the front or rear wheels in place and try spinning the opposite ones. Hope this helps

[@aaronpeters1770]

@@FullThrottleRC so i can hold rear tires and spin the front ones as if it were a rear wheel drive. Do the same to rear but it has resistance which i thnk is good. Just freaked out bc ive never done diff work b4....done everything else on electric, but never a diff

yeah my 12 years old Traxxas Stampede 4x4 is mostly running on bone dry diffs..was wondering why it did not turn luke it used to... who knew that differentials had an effect on turning radius XD got my saturday morning planed loll

[@FullThrottleRC]

Absolutely! Diffs can completely change the way a truck drives and handles. The Notorious performs much better, in my opinion, since I put some heavier weight fluid in the diffs. Good luck!!

I rebuilt mine with 300 000 (three hundred thousand) silicone oil.

[@FullThrottleRC]

All three of them? That sounds insane!

[@DingoOzWolf]

@@FullThrottleRC comes out of the bottle like honey from the fridge. I've read some use 1 000 000 CST oil in the centre diff and 500 000 CST front and rear. For now, 300 000 CST is in all three and power transfer to the rear diff when the front is off the ground is much better.
