#1 Weakness of the Traxxas TRX-4 - What is most likely to break?

Very true had to replace one front of my Defender after around two years also.....

What tires and beadlocks are you using on this trx4? Looks awesome!

Yes, I do have it handy. I always have spare gears.

Then why buy?Mine is junk and the one I bought for my son.same problem, same day . Done!

I know this is years later but I've been lucky with both mine. Upgraded hh trailer master and 1080p esc. Been bound up pretty good and no input damage

Hey man. Are you from china or japan?

Haha I broke the axle and not the gear😂

Never break them you drive like shit and thats the problem

This thing is built to last. Well minus the steering servo and motor. I have the 2021, all black Ford Bronco!. Over 250 miles of trailing, hiking trails in my area and all I’ve had to do is apply grease to the portal axels and differentials as part of routing maintenance once a year and looks and feels like it’s ready for another 250 miles!!!

I have clearly looked after my TRX4 Sport too well, my gears are still perfect even after 2 years of abuse, just uploaded a maintenance video to my channel stripping the portals and diffs

So, I bought one when the first"kit" came out. In the last 4 years I have put at least 200 miles, hundreds of hours. Running it with a 3800 kv mamba x combo.....so I wasn't nice to it. In all this time, I have broken both fronts(replaced with Traxxas chrome moly in just the front) but kept the normal input gears in the rear. Truly remarkable how many hours I've had on it without that much significant wear

Thx you ar verry help full

i love the look of the defender, the light upper weight of the blazer, and the pin-less and other upgrades on the new bronco. can't decide which to get... is the defender substantially weaker performance wise than the blazer?

Is this only a problem with locked diffs? My trx4(bronco orignially) is almost 4 years old with bashing and jumping included.the only thing i ever broke was the front bumper mount and after that nothing else has given out, i did put a castle creations mambax and 3800kv crawler motor, but ive never broken anything else.

Hi; New subscriber Mike here....Question: Why is it called a Servo "Horn"? Thanks!

Broke front left one today after 3 years of use

Huh, i would never have guessed. I've never broken one of these with all the abuse I've put my rigs through. Alllll kinds of other things. But never this.

My TRX4 defender has allllllot off milage and is still going strong.

Its crawling, not bashing or jumping. Crawling is like barbeque.. take your time and enjoy. No rushing 🤣

Yup, I’ve broke one. I heard that the upgrade on it from traxxas is even weaker

I greased portal's and diff with cheap smelling marine grease is this safe long term for plastics ??

Traxxas has "heavy duty" ones for 100 front & rear. They just as good as the ones you mentioned? Also, wondering if YR axle swap would solve this all together?

Sooooo, lesson for the day is......don't bash it since it's a CRAWLER! Yeah, I know right?🤣

I have the defender from Traxxas. My second T and my last. Super expensive here in Canada. The inner fenders drove me nuts. Made putting the body on a major jiggle and wiggle event with plenty of cussing. Inferior electronics, had to stick paper in the transmitters battery box just to keep the batteries in place. Flimsy body tears right by those inner fenders as well. My Axial has gone through hell and there are no rips. All in all, wish I had bought something else but I'll make it work.

Every stock electronic part went out in less than a year. Except the motor which is pretty weak IMHO.

Thanks!

There are tons of aftermarket options to bulletproof the portal input and output gears, from KYX, Yeah Racing, traxxas, devil rc.. Front and rear, All made of better materials.

do you have a video on how to make the front axle move faster then the rear

Is that your washing machine going in the back ground? LOL

Sir are you a Filipino?

I can't wait to purchase one of these trucks

I did just the opposite corkscrewed the shaft gear was fine.

I just broke the rod end cracked alongside the thread

salut!!!!! d'abor merci pour tout ses renseignement!!!!! vous êtes aux top merci!!!!!! et ses encore mieux avec la traduction en français on arrive mieux a vous suivre super , jais bien pris en compte vos conseille merci a vous , a bientôt!!!!

Good video, question is if you strengthen the portal input gear and use the heavy duty chromoly input shafts, what's the next weakest link? something in the transmission or the drive shaft? What's cheaper and easier to replace?

And no one I know has complained ablit the portal input gear stripping

The electronics are great in the trx 4 I stand behind them the steering servo yes I agree it’s under powered the portal gears are fine I’ve never stripped mine

You’re awesome man big help getting into the crawler stuff!! In the middle of assembling my trx4 right now haha just watching videos for a break 😂

Wrong! The weakest part, other than the electronics, is the plastic servo horn. First thing I always break.

Mines doing good. I've had mine since 2018 and only replaced the servo 1 time. I don't know if I'm not bashingbjard enough but. She's floating good.

What is a cheap reliable brushless upgrade?

I wonder if you heat threat that axle part , getting it red hot and toss it in water to get the metal harden enough to
handle the stress , maybe that will work?

I have a problem with my trx4 bronco, put the new axe v2 in and everything works fine except when I lock the rear diff. The truck seems like it's binding up and hops/lunges especially while turning, doesn't matter the speed. Any thoughts anybody?

My portal input gear broke on my TR4 Blazer, but also my axle housing broke too. Do you have a link to a stronger front axle housing for the TRX4?

Interesting. I have only 1x trx-4 (bronco) , with Axe 550 3300kv system , with 15t Pinion gear and running 3s all the time -> i am getting pretty high speeds. I am more bashing then crawling my trx-4, and really hard. Few things broken, few bodys broken, but this portal input gear - newer :O . Maybe they are delivering different versions / different quality of this part ? Strange

Utter bullshit.
There is one soft spot that's the panard mount chassis side. If you break output gears you land with wheels spinning full force

I'd imagine the high drag-brake we all use puts some strain on them too.

Funny, broke mine 2 days ago after jumping it off my neighbor's Rustler ramp. Guess I'll stop doing that!!!
