- One of the bits on the CC01 that always causes problems is the steering, more slop than a school canteen. So today we're going to fit the GPM CC048 steering kit.

Thank you for this, most informative! I'm in the process of building a CC-01 Landfreeder (SILLY name!), as I'm writing. I also got an aluminium front steering assembly, but mine is from Integy. Although it doesn't look a lot better, it seems fairly robust. One difference - I used JB Weld on both ends of the bellcrank. It's a very strong epoxy, I'm hoping for the best....
I also did up the upper and lower control arms, C-Hubs, and spindles. I'm hoping that all this will take most of the slop out of it! haha
I've never built a CC-01 before. I just watched a LOT of videos like yours first!
Same bloke, new, all R/C channel! The JB Weld on my CC-01 is STILL holding fast! 😊 My front suspension still has NO slop. It's a shame that I couldn't figure this out years ago, when these were very popular. I believe most have simply given up on them! 😕
*TOO* bad, because they're great Trail Trucks, looks Scale, and with some tweaking and screaming, they make fine Rigs!

Thought of this too! Many years back now, I did this RcMoJo mod and it worked great! I’m picking up another CC01 kit to build for old times sake and am going to try this out!
Thanks for all the tips I'm glad I'm subbed
Interesting. I made a similar thing with GPM and Align parts, to realize a clearance-free Push & Pull Steering.
Sadly I made not enough pictures, but anyway I´d done a video of it...
Very educated video, thanks a bunch for the fix!
I have one question though what part number did you use for the screw pins?
Traxxas sells 4mmx13mm (part no. tra 5145) and 4mmx15mm (part no. tra 5189) which did you use?
I think they were from an original T/E-MAXX driveshaft, seems they never got their own part number. A shame as they're a neat part.
I've got 2 more sets to make up, actually I was hoping to have had them done back in May... For those I was planning on using M2.5 cap heads, drilling for clearance on the first half of the outer part and the shaft, then drill and tap the last bit for the screws. With some loctight in there it should hold just as well as the screw pins. The screw are probably cheaper too!
RCMojoTV Thanks very much for that quick reply! Im gathering the materials now and ill see how it turns out :)
Im not a fan atm either. I hit the skid plate with a dremmel flush. Made big grooves at the openings and it was free. Not smooth but free.
I tightened down the skid plate and it locked up again. So i added button head screws into the lowest skid screw holes. So they raise the skid slightly.
Our truck didnt have screws there anyway and it worked a treat.
The keyd design is dumb they could easily do better it wasnt even that cheap. Gpm has taken a dive in my book.
I installed a cheap china assembly into other truck it cost 70% less than gpm but came the exact same way.
No instructions. Poorly fitting parts and not really an improvement over standard.
But the soft cheesium shines so..
So to keep bothering you but where did you stumble upon that aluminum rod? Thanks for being so helpful.
Any engineering material supplier will stock aluminium rod, the issue is getting a precision fit inside the bearings as aluminium rod generally has a poor tolerance.
If you can't turn down the rod on a lathe, or even a pillar drill you can try visiting somewhere like a model shop that stocks metals, try the rods until you find one thats a good fit.
The third way is finding a local machinist and asking them to make a rod that'll fit the bearings, it's such a small amount of material they might just have an offcut they'll trim up for a couple of beer tokens.
As to wether I’d recommend the CC01, I would, as long as you know what you’re getting into. It has a fair few niggley issues we’ve covered in the videos. If you think you can tackle them it’s a lovely bit of kit!
thank you sir... is changing to alloy steering assy improves its turning radius?
Wow, GPM did not figure out how to do this properly!
Tested in an office I bet, also production metal may have been sub-standard.
I was thinking of getting a cc01 do you recommend it
Great tutorial.
Here is what you need Jack *****

Would you be interested in making another one of those GPM steering mods ? I would gladly pay for it and your time. Pretty please :)
Y is it that some gpm steering kits are better then others they are the same thing
Manufacturing tolerances. A dimension will have a +/- variation, the smaller the variation, or the tighter the tolerance the more expensive it is to make. In the case of the steering kit I reckon they’ve undersized the the flats on the shaft to make sure it will at least fit. So if you get a kit with undersized holes in the arms and oversized flats on the shaft there will be less slop.
The way around this is to have more points on contact, with the 2 flats there will only ever be 2 small contact points at the ends of the flats, these will wear down in no time with the slop. So they could use a spline instead, having 25 or so points of contact, much like a servo. The issue is again cost, machining a spline is a relatively expensive process.
If the market would handle a £50 steering kit I’m sure it would be a fit and forget part, but you get people complaining about £12 kits!
Absolute crap! Bought this thinking it would be a geat upgrade to reduce the steering slop from the stock plastic parts. I was wrong! Kit did not come with a manual to begin with so I had to figure out how to put it together. When I finally figured it out, the head of the screws would rub against the chassis. Biggest issue was the to arms that "key" into the pivot shaft was so shallow and soft that it would "round" itself out resulting in even bigger slop and no steering consistency. Typical cheap Chinese parts!! Garbage. Would never buy GPM junk and try and avoid buying from a greedy, money hungry, disrespectful, dirty , ugly, child labouring, animal cruelty, environmental destroyer country. I googled about the product and found similar issues that I had. For the record, I have 20+ years in the hobby and have never encountered anything this humiliating.
Hey I watched your video and did a steering mod of my own can you come check it out
GPM hop ups are made in piece of shit aluminium, softer than tamiya plastic ... I bought GPM once, never again !

Had the same issues than you with these GPM part and was so angry I almost kill my wife and children trying to put this shit together on my cc01...
