I have a Gen8 with a 4 wheel steering mod, and I blew out my rear axle. Not the shaft itself, but the part that attaches between the steering knuckle and the axle tube. Ripped those three little screws right out and destroyed the axle tube/diff. Just got it back on the trail with an upgrade RCAIDONG aluminum diff, steering knuckle, and portal boxes. Took a bit of fiddling to get the pinion and ring gear set right, because it's a non-shim setup, and I didn't know it the first time I put it together, and I could feel that the gears weren't meshing right. Took it apart again, removed the outer axle tubes from the center diff, and tapped the center carrier back and forth until the ring gear and pinion were moving smoothly. Seems to run great now. Considering posting my own assembly and install vid when I do the same operation with the other end.

[@ExocagedRC]

Yeah do it. Tech like that helps others.

[@Ken-BurnForever]

Thank you for this very clear video. I was not looking forward to servicing my front portal, but this video makes it seem less scary

[@KC1UER]

Great info as always. I just got my Gen 8 and was happy to see my portals were well greased from the factory. After my first run which involved water, I cleaned them out and put marine grease in for some added peace of mind.

[@jakeg2312]

Front Right pin and gear broke on the portal axle on mine today. Heard Redcat is really good about their warranty though so fingers crossed! Went ahead and ordered more pins and the upgraded axles and housings from them too.

[@rchokelal]

Thank you. I am swapping over to the HD Axles.

[@rcsendandblast1579]

Planetary gears are a trio of 3 gears. Portals have 2 Much love man. Great vids. I am building a gen 8 from the ground up. All upgrades included 👊😀

[@Cager-wv3uk]

This video helped me get mine repaired. Thank you

[@davidcarroll2035]

I’m receiving mine today, only ordered it yesterday, and yes I know the axe version is coming out but I’m more than happy with this. I’ve watched a lot of videos on here about it, and if I listened to thee quarter of them I wouldn’t have bought it. Lots of haters and moaning out there. This is a nice video and I feel excited to be getting mine x God bless bro.x

[@ExocagedRC]

David Carroll awesome. It’s possible the latest versions have some upgraded stuff like axle shafts. Not 100% on that but it’s very possible

[@NaturallyRC]

Solid walk-through, but hindsight is 20-20 of course, and we've learned a thing or two, eh? One is the "bit thin" mount at 1:13 which immediately failed for a long list of folks, undercutting (some argue) Redcat's hopes of joining the top-tier brand names. The fix is SSD's affordable alloy replacements, but if you wait until the links rip out, good luck saving the axle housings. if you do fix those link mounts, the Gen8 chassis is a budget-friendly platform you can count on, and one of my favourites. Cheers and thanks, Joe.

[@jimratzlaff3112]

Really helpful video. I appreciated how clean you had your gen8.

[@ExocagedRC]

Glad it was helpful!

[@richarddow69]

Again a spot on DIY video. Thanks.🤙🏻

[@Weemanfaescotland]

Brilliant video 👍thanks for doing it, 😊 Kind regards James Fae Scotland 🏴󠁧󠁢󠁳󠁣󠁴󠁿 Part of the UK 🇬🇧 👍

[@STEVOD313]

Nice in depth look, thanks for sharing this info

[@the-drifter-42]

Hi Stevo!

[@lonnienunes]

Thanks for video just got a gen8 about 2 weeks ago.

[@Andrew-hh3ol]

Redcat makes awesome plastic, their stock metal on the brushed blackout xte is monkey metal zinc but they sell upgrade ones which I haven’t tested yet

[@MGracing2023]

Buena demostración de calidad en transmisiones, es lo que quería ver!

[@byknmikerc7153]

great info! a lot of haters out there dissing this truck! I love my gen 8 run it more than all my other rigs, might just be the scout? lol

[@evileyes79]

If you purchase one of the gen8's I would recommend buying the aluminium diff upgrade kits with it, 20 mins in mine twisted the rear diff in 2 on a simple rock climb, still awaiting replacement parts.

[@krashkingrc9715]

Awesome video looked great inside cheaper priced truck but definitely built nice and can't believe the grease that's good

[@sudsrc8261]

Seen two videos now where people have found the portals dry. But a buddy on FB said his were greased. Lesson to be learned? Best to check them just in case you need to add some.

[@ExocagedRC]

yep super easy to check them to be sure

[@stpbasss3773]

Mine are greased

[@grumpyyerr]

Great vid. Newb to crawling and these sort of trucks but not to rc. Recently acquired a used Gen 8 and enjoy it. Guessing mine was not shown much love and hence why I'm checking this particular video out. My question is there any caster adjustment for the front. My right front is leaning something fierce. Hoping it's not a bent housing. Thanks in advance

[@orkiks]

awesome video. Can’t wait for my portal axle for the gen 7

[@danielkonrad1444]

Did you get it? Are they worth the money? Thinking about buying them. Did it increase the steering angle?

[@larrylooney4495]

That's quality redcat is the way to go now

[@trystanmarshall1867]

I checked my gen 8's portals and they where well greased I will be putting some marine grease in them including the diff housings

[@ExocagedRC]

Trystan Marshall cool

[@oldsjunkie1]

I like the bearing pin capture design. Way too many hours putting shrink-wrap around CVDs pins!

[@mxsty8829]

Should I put locktite on the drive shaft where it meets the diff? To avoid it frost coming out?

[@linlinlixin2637]

I hope Red Cat makes locking diffs for the gen 8 in the near future cause i plan on getting a gen 8 next week.

[@christopherharris4916]

I am on my 3rd rear axle housing and third set of front portal gears

[@ExocagedRC]

Christopher Harris you should watch this kzbin.info/www/bejne/aWbCeoGpbM2irrM

[@christopherharris4916]

I have

[@ShenRC]

😁👍Cool your ripping it all apart... now I think I will be taking my portals apart and putting some grease in them seems that's the spot they did not grease to good.maybe take the axle covers off to check the big diff gear.

[@ExocagedRC]

Yeah opening the portal cases and diff cover can be done fast and easy. I did add grease to all portal gears.

[@jerroldtaylor3047]

How is the grease in the transmission mine sounds a little growly

[@stinky3shoes491]

So many gears . the more I watch videos about the gen 8 it gets more crazy . lol I like just simple knuckles and hubs . gears there!!

[@ExocagedRC]

This is actually a simple truck to work on

[@nelsonkarrer6961]

Will they fit the gen7 sport

[@digrannirctruck3771]

Very aprecciaty 🥺

[@scottperry5454]

Great video, how do you feel about using dif fluid instead of grease? I'm thinking fluid may quiet it down a bit. They are sealed right?

[@ExocagedRC]

I doubt the boxes seal well enough to hold in an actual fluid.

[@MakeItHappenOriginal]

I was curious on that aswell.

[@stpbasss3773]

Yeah diff fluid it usually used inside the diffs in the little internal gears an it has a gasket, don't put diff fluid in a fully locked diff crawler there is no point it will leak out. When I was new to the hobby I thought diff fluid went where the grease goes and I filled my diff cases up with fluid and it leaked out everywhere lol.

[@leemitchell3020]

Might be nice if you reviewed the V2 of this rig that's out now. That middle hump is gone and a few other upgrades. Just saying

[@ExocagedRC]

yeah I know but I still have the OG one and already have a better belly from Bowhouse RC

[@akeefe6]

@@ExocagedRC I can't seem to find it anywhere online. Do you know the measured width of the chassis and axles? I'm trying to figure out if I should buy a gen8 chassis for a project.

[@ka4172]

Is it possibel to shave the diff cover some mm for more ground clearance? It looks like the diff cover is a bit larger than the axel gearbox.

[@ExocagedRC]

its possible to do that, I don't know if the gains would be worth it or not.

[@ka4172]

Nice video ,why Red Cat put the link fixing carries on the axel so deep (easy stuck on rocks)? On the TRX4 the axel clearance is way better.

[@ExocagedRC]

I’m sure we will see all kinds of mods for these things very soon

[@stpbasss3773]

They pumpkin sticks out way farther so it really doesn't matter

[@sivaanmkrddy2275]

How much cost rear axel,where is buy?

[@matthewneufer1758]

Red Cat makes decent RC I have few I have. volcano 18th I made brush less with a motor and ESC from dynamite Losi Minni E Truggy it is sick quick I got a volcano Exp brush less that things a beast I got a Caldera SC I put momba max SC 3800 kV it's stupid fast it's a small 10th scale it's so lite, I had to dremmel alot majic to get it to fit..

[@rcpatapouf]

Great

[@randallbatson611]

I lost one of the bushings what do I do

[@BLACKBOX1004]

👍👍👍

[@BD-Daddy]

Very cool video! Oh! Are these V2 axles? Or Version 1? Thanks!

[@ExocagedRC]

I think it has V2 now

[@stinky3shoes491]

How important is it to replace the knuckles and hubs with aluminum ones?

[@ExocagedRC]

we don't know how durable these are just yet, these may prove to be strong and not break but I will be getting a set of metal ones as soon as I can.

[@jakefuller79]

Subbed up very detailed tear down thanks!

[@MotoCampAdv]

Please help my center drive shaft pulled out of my front differential the little screw holding the pinion gear some how backed out causing the drive shaft to separate . I know how to reassemble but I lost the bearing that sits in the back of differential where the hard pinion inserts . I don't know the size I need to order for a replacement . Thank you

[@ExocagedRC]

pretty sure its a 5x10x4 bearing in there, I don't have one to check but you could send redcat an email and they can verify

[@redhay9481]

What’s the stock tire height on the gen8?

[@ExocagedRC]

I believe they are 4.65”

[@redhay9481]

Oh thanks I’m looking at buying one this week and will be looking at tires also and wanted to go a little bigger

[@ExocagedRC]

@@redhay9481 Some guys are having issues with axle pinions with larger tires and more power, the proline super Swamper XL is a little bit larger and look great.

[@redhay9481]

I was thinking about going with a 4.7 tsl bogger

[@skirmich]

The bearings on the portals are tiny compared to those on the TRX4 specially the output bearings.. Those mod 1 gears are meaningless if the bearing is undersized for the load.

[@ExocagedRC]

So far I’ve not had an issue and I haven’t heard of anyone else having an issue yet. They could’ve been bigger but they are what they are.

[@skirmich]

@@ExocagedRCYeah the smallest bearing in the TRX4 portal (Input Shaft Small) 4x10x4 is Bigger than the Redcat 4x8x3 for the same application. And the difference in the output shaft alone is noticeable: TRX4 has 6x12x4 (Carrier Bearing) and 6x13x5! (Output) vs Redcat 4x8x3 (Carrier Bearing) and 6x12x4 (Output) Again is probably ENOUGH for a low speed crawler but is something to note in future videos, The TRX4 drivetrain strength is SUPERIOR overall to that of the Redcat Gen8, Not only in the portal? but also on the propeller input shaft bearings, Transfer and Transmission all of them have bigger bearings in the TRX4 with Mod 1 gears and a healthy dose of grease in the portals/transfer/transmission which at least in the portals seems missing in the Redcat.

[@stpbasss3773]

The redcat has the same size axle bearings on the end as a Slash because mine was missing a front axle bearing when I got my gen8 and I threw an extra Traxxas one I had in it.

[@bigmanrctoys8484]

I abuse my Gen 8, and I never had a bearing fail since I bought the truck. I stuff those portals full of synthetic grease and there's no issue ever.

[@พิชัยแพสถิตถาวร]

I want Gen8

[@stevecampbell1252]

Take the bolts loose??????????????????

[@ExocagedRC]

LoL I took a bunch of bolts loose

[@GuyonaMoose]

Major design flaw? No outer bearings on the axle tubes. Dirt and water will alway find its way into the pumpkin. Kind of a deal breaker for me honestly

[@clarkb1900]

7:14 He pulls the shaft out and the outer bearing comes with it. It definitely has them. You can only see the rears in the vid, but the front probably has them retained behind the c-hubs. 2:00

[@rccustomscale4989]

Hello you need a nail care!😀

[@ExocagedRC]

LOL yes!! I'm a mechanic in the real world and I actually use these meat hooks. lol

[@johnfulwider7510]

I found a problem with it. I broke the pinion gear. Stripping 3 teeth off of it.... hopefully the warranty will cover it.

[@ExocagedRC]

I've seen this a few times in their FB group and yeah I think redcat is taking care of it.

[@ANDREWH7282]

Haha no left over screws
