very nice 4Runner
First bit of carnage this weekend. Step one: truck takes a full immersion swim in the creek after crazy kid drivers almost make it across a narrow bridge. Followed by parent rescue with (I promise) no swearing and only textbook-correct parent words. Turns out the electronics are actually waterproof, at least for a few minutes, which is nice to see. The receiver case was also almost completely dry when I opened it later.
I thought that would be it for the day, but a few minutes later we had step two: rear axle case randomly splits in half near one of the shock/link mounts while the kids were driving in some bark. I guess the fastener holes for the shock mounts are a weak point since there was minimal abuse going on in the moment.
Here’s the truck right after the swim / axle breakage. Interesting angles for the rear wheels, lol! The grass cleaned off nicely with a quick rinse and compressed air.
Here’s some close-ups of the rear axle:
The axle didn’t fare so well either
The locker looked fine when we opened up the case.
So now we have new goodies on the way: SSD Pro44 rear axle case and Vanquish chromoly axle shafts. I’m excited to see the SSD axle cases and how they perform; they look like a great deal and a nice balance of strength and weight! RPP was coincidentally having a 15% off sale this weekend, so maybe it was all fated to work out this way, [emoji106]!

That's crazy. And why I hate Axial plastics...
No doubt, and I was hoping the first breaks would come from a more glorious moment that bark driving, lol!
I was surprised. The new plastic seemed much better relative to my v1 G6 but it’s apparently brittle. The wall thickness for the axle (easy to measure now, lol!) is around 0.14” - would probably be decent except for the fastener holes. I think we’re on the unusual side, though, since I haven’t seen this failure in other threads.
One bonus is we’re back to wrenching. I was starting to look at other kits ... the Rock Rey looks like a great deal and we haven’t tried a Losi kit yet!

The SSD Pro44 axle cases arrived late last week. The parts are nicely made; great idea to combine a nylon center housing with metal axle tubes. Here’s the housing before we got started
Along with the Vanquish axle shafts
We re-used the stock gears, bearings, and lower link / shock mounts. The axle housing fit together well with impressive tolerances for the center housing / tubes and the bearing retainers for the gears. Here’s the partially assembled SSD axle resting on the stock corpse
It’s important to seat the pinion gear completely, otherwise you end up with a pepper grinder. I used a hex driver threaded through the mounting hole for the drive shaft to pull the pinion into place. Smooth as butter at that point. I had some spare 2 mm scale hex bolts, so we used these for the diff cover; happy with the way it looks!
We added some Locked Up RC scale hubs that I had leftover from another build to the rear wheels. We used lock tight to secure them in place. Guess I’ll have to buy their hub tool now, Lol!
Here’s the axle mounted on the truck during a backyard test drive.
Everything was going great at this point, so we returned to curb jumping
And some crawling in the green space across the street. It crawled over this high curb like it wasn’t there - impressed with the ability of this truck to tackle tall obstacles!
Sadly the joy didn’t last. After roughly 30 min of glory we found the next week spot and busted the Panhard mount at the base of the shock tower. Does interesting things to the steering when the trackbar is no longer attached. Note the broken plastic next to the shock, :shock:!
So we’re back to waiting for parts. We’re going to try the Xtra Speed aluminum front shock towers (includes the Panhard mount). They’re inexpensive, have a double sheer mount for the trackbar, are made from a decent grade of aluminum, and look nice. I couldn’t bring myself to spend the $65 required for shock mounts from other vendors, even though they include all four corners - hopefully we’re not just flushing $15 for paper weights ...

The Xtra Speed aluminum shock towers arrived and we installed them yesterday. It was a nice afternoon, so we took the repairs outside and used the patio furniture for a workbench. The packing for the towers is nice, with a separate space for each one so they don’t ding each other.
The towers are well made and closely match the design for the stock towers, aside from the Panhard mount, which I think is more stout on the Xtra Speed part
Here’s the passenger side tower installed on the truck. The installation was easy and the part fit perfectly
Here’s the driver’s side, also a perfect fit. I hope the aluminum is reasonable quality; we’ll find out soon enough if my kids are able to bend them up, Lol!
There was a small conflict between the Panhard and the servo arm (we’re using an Axial aluminum arm) that limited the steering range. The conflict was easy to fix by adding spacers under the servo. 1.5 mm spacers were enough. Here’s a picture of one of them on the end of our 5/64 driver
If you use this trick, be careful to not raise the servo too much; at 3 mm, the arm runs into the frame rails.

I bet this comes up for a lot of us. The clearance window for the servo horn and Panhard mount is only a few mm in either direction. I’m happy that we had spacers with the right width laying around. Every time this happens, I think about how I should put together some magically organized and perfectly stocked parts bin - but then the problem passes and so it goes, Lol!

We took the trucks crawling at Addenbrooke park, which is south of us in Lakewood, CO. The park is recommended on the Crawlerado crawling atlas in the RCC regional section
http://www.rccrawler.com/forum/colorado/91673-crawlerado-crawling-atlas.html
The park has some nice crawling rocks on one end of a pond with fantastic views and a stream. Awesome day to be outside, with mild temperatures (for here) and clear skies. We had a great time crawling on the rocks and testing out the new hardware on the SCX10 II.
The truck did really well, although we’re up to round 3 carnage, this time the front bumper, which snapped clean off at the rail mount after a gentle hit off a slightly tall rock. Rough times for the Axial plastic, :shock:! The break is across one set of mounting holes
I had coincidentally just watched a video about bumper options for the SCX10 II.
https://m.youtube.com/watch?v=oB0Hytm13mE
I didn’t expect to make use of the suggestions so soon, but here we are, [emoji106]! We’re going with the Axial AX80039a bumper.
https://www.rpphobby.com/product_p/ax80039a.htm
It seems like a decent compromise between cost / function / looks and includes light buckets. Still Axial plastic, but it can be mounted up against the body, so hopefully it’s better protected than the stock “cantilevered plank” bumper. We’ll find out, Lol! Nice weekend for replacement parts given all the Labor Day sales.
I have the SSD bumper in the video on my v1 truck, btw, and it’s fantastic!

i love AddenBrook; left lakewood 2 years ago for St George UT. long drive down from Arvada . Bonus, you can just hop over to BundCaks R Us for a bite.
Is the water level down low enough to get on the rocks near the water?

The new bumper arrived. It comes with some other goodies, including light buckets / covers and a front bumper mount.
It was easy to install. The stock mount is a little bent, so some extra pressure was required, but it was easy to get on otherwise.
We all like the look. There’s a minor interference with the body, but nothing substantial. I may trim the front to fix this, or just wait for it to resolve itself in the next round of driving destruction, Lol!

First snow day!
It snowed a few inches last night despite 60 degree temps yesterday afternoon. The large tree in our front yard also decided to unload most of it’s leaves overnight. The two together made for an excellent, low traction surface perfect for the SCX10-2 and my Bomber.
Here’s the two trucks after 20 min of doughnuts. It’s important as a parent, you know, to encourage only the best and most conservative driving habits, :shock:!
Can you see the SCX10-2, Lol?! It’s on the right - kids wanted to run it without the top - no patience for getting the body clips!
Here’s a close-up
All was fabulous for about 40 min and then more carnage in the back axle. This time the cap screws holding the locker to the ring gear sheared off
The ring and pinion both look fine. The locker is also ok aside from the embedded fasteners that broke off flush, so no hope for getting them out, at least with my tools. Shame to throw away a part that’s perfectly good otherwise. The heads came out of the ring gear easily
So back to getting parts ... I ordered the Vanquish SCX10-2 spool
https://www.amainhobbies.com/vanquish-products-axial-scx10-ii-spool-vps08070/p523466
It should be here by Friday. I plan to pair it with some stainless fasteners from my parts bin. I should probably change the fasteners in the front also. Have any of you had similar problems?

Ok, so it took longer than I expected to get back to fixing the rear axle. The Vanquish spool showed up right away, but I decided we should go with some better grease and ordered this separately. Plus work and a few other things kept me away from the workshop. I must be one of the last people in the RC world to adopt CowRC Udder Butter - setting all the trends, Lol!
http://www.cowrc.com/#!/Udder-Butter-2-5oz-Pre-Filled-Syringe/p/59318081/category=12842156
The CowRC shipping / customer service were impressive, as others have pointed out. We’ll be using them more in the future.
Here’s the Vanquish spool. Always fun to open one of their packages.
The parts went together really well. We used stainless fasteners to attach the spool. Hopefully the stainless fasteners fare better than the ones that sheared off last time.
The axles slid into the spool easily, but didn’t have any noticeable slop; pretty impressed with the quality machining on the Vanquish part.
Here’s the re-assembled diff with a healthy portion of the Udder Butter
I’m hoping we can do some test runs tomorrow. I’m guessing the next round of carnage will involve the front axle, but we’ll see ...

On the old locker, u may try a smaller drill bit than the screw to run them back out. Drill from the end of the screw, not the broke end, n the bit may get a bite n back the screws out. Just be careful not to get inot the threads
