Hey man, I just broke my Axle housing last night, and this video is a LIFE SAVER. Appreciate you taking the time to do such a detailed breakdown. That all being said, the cable length thing scares me. I’m not sure how I’m going to get that exactly right. You got time for a drive to New Hampshire? Lol

I have a feeling that if maintenance is not made a priority with this truck, the cable system will go all to hell. I keep thinking of a bicycle brake system, and what a pain it can be if not properly maintained. Thanks for taking on this video Josh. I have been wanting to get a good look at the internals.

Reverse a Capra transmission and run the dig unit to the front axle. Grind down the locking lugs so it’ll only operate drive or freewheel and no more lock. I’ve driven my trx6 in fwd and rwd just for fun and it’s crazy how much less traction it has. Especially fwd lol

I have one so thanks for this, Josh. To person below making a comparison to bicycle brakes, I'm a bike guy. I work on IT stuff in a bike company and wrench my own bikes as I have for years. That cable gauge and wrap is ever so slightly smaller than that of high grade bike cables what last for years if taken care of. In short, flow a little lube down the top ferrule once in awhile and pro'lly doesn't need saying around here, don't apply high pressure air/water when cleaning. If you mess with servo placement, etc, mind the bends and check for smooth cable movement and adjust those servo limits. Should be worry-free. It's a ridiculously beefy cable. My worry? That shift horn looks like fragile crap. Mind those servo limits. Not diggin on the plastic diff cup. I took a quick look on the Traxxas site and it appears they don't offer replacement cables. Surprising as they offer everything else down to the screws. Pro'lly on there somewhere but if not just keep packing grease down that thing and it'll live at least 7 years, even with water immersion. It's stupid-beefy for such a small thing. I'm guessing most users will get bored with the lot of it and somehow hack it to permanently locked or there will be aftermarket locking stuff. I've only had mine a few weeks and I'm almost at "Meh, don't see truly useful functionality in this. Just lock it" Still, kinda neat I guess. Nerd factor 7, useful factor 3. I have a few rants elsewhere about how I reduced mine to all lock/unlock vs. that goofy front/rear thing. Bless them for trying? The rest of the axle seems gravy for sure though! Portal are awesome!

Hey, I think it's a nice truck, but what I find with most rc cars is the fit of the bearings in their respective housing. As an retired auto tech I don't like slop. I know I know but it drives me nuts. I usually shim them. Your thoughts? God Bless Ya Dave
@rustandoil
@rustandoil 7 жыл бұрын
David Aarons I agree it would be very easy for manufacturers to put a few raised ribs in the bearing housings (like a internal spline) if they feel that they can't hold the tolerance on the moulding to make the bearing a snug fit

I have had my TRX4 for 4 months now. I run it every day and absolutely no problems with it. I have worn out a set of tires already but no issues what so ever. I use high temp wheel bearing grease, red, in trans and axles. Runs quiet and smooth. I also put a small amount of grease inside the slips of the driveshafts. This is one of my best RC's.

Actually to make it rear steer you would have to do quite a bit of work. You would need new rear axle shafts and upper portal gear, new back half of the rear portal that is built to screw onto the C-hub, a rear servo mount of some sort (axle mounted unless you want to figure out a panhard too), plus steering linkages.

Harley Designs Forgot about the built in caster of the front c hub, but sounds like most front axle parts could be made to work with a few new parts needing to be made from traxx. I'd go axle mount servo for the rear.

There's a lot more to like about that!! 👍👍 I actually think I would GET a TRX-4 Sport, and just add a selectable Front Diff, leaving the Rear locked.... Josh, I know you're a Comp Crawler, and the idea of ANY open Diff, could make you break out in a rash!! 😂😜 LOL I would really appreciate the extra Steering control, and the MUCH lower stresses on the whole Front Axle. Lock it only if I need it. 😉😎 I do hope by now - SOMEONE is making a Metal Diff Housing for this... With all the Fan-Boys, surely somebody is making one. Thanks! That was a good look inside.
