    Tekno M6 CVD's problem...

    I just took my rusty out for a run, ran great for a while. I have slash rear arms, because the slash M6 cvd's weren't long enough for the rusty rear arms. So anyways the wheel was wobbling a little. So i took a look and the innermost bearing was exploded. And the ring was cracked. I email Tekno. Just waiting on a reply, but i will also call them tomorrow after school.
    I thought Tekno was the best? But apparently not. And i only have ran these parts 3 times on 2s Lipo. So far not so satisfied with them

    Maybe i can get some other bearing that are better? If so what company?
    Its a 10x15x4 bearing...

    EDIT: are avid bearings good? If so what are the best? Like which ones will be the strongest? Ceramic? Metal? Im not sure. And I'm not looking for maintenance with these. Just pop em in and go. I would like for them to last a good amount of time.

    I don't know about the bearing but I have seen alot of people having problems with Tekno driveshafts, people say that you should just save up for the MIP.

    I have tekno and never had a bearing failure running it for a year now on my rally GT8, as the matter of fact the bearing I have are from the XO-1.

    Hmmm, this should be a rc "hot topic" driveshafts. But I haven't had the plastic slash shafts fail on my rusty vxl, the holes just get egg shaped after a while. This means that they will eventually tear through the plastic u joint too. I have had the slash shafts for almost a year, it might seem more worth it to replace them every once and a while rather than spend $50 or more on steel driveshafts. I may very well be wrong. I have asked this question like 5 times but what driveshafts hold up the best besides MIP-X-CVDS? I was thinking about the teknos. But hmm

    Stick with stock arms when running tekno cvd and set the droop to a point were it wont pop out.

    Tekno M6 CVD's problem...

    Ok, but what bearings are the strongest?
    I am using stock slash arms. And i will set some droop so the bearings wont pop out anymore. And i already have these so i want to stick with them.

    That seems a little insane, but maybe the traxxas 1951R shafts are a consideration? Or is that not good? Low ground clearance for jumping doesn't really work too well. Sorry to annoy you with this madness. I just want to have a good driveshaft purchase and be able to have them last a long time

    I may be overthinking this, I'm starting to think that the bearing just popped out and i didn't notice it right away. And as i drove it with the bearing just loose, i think it just fell apart. That may be the problem.
    I looked into the traxxas CVD's, they were just to expensive and didn't have the bigger bearings. I think the tekno CVD's are great! Just my own fault that i didn't notice the bearing popped out soon enough to save it. But it only fell out because i didn't have my angle correct and it had room to slip out.

    Interesting. I'm on here a lot and I haven't seen that. Perhaps personal preference is influencing your perception?

    Avid bearings are the best bang for you buck. I've had a full bearing kit in my Summit for over a year now with out any issues. I'd go with the revolution bearings IMO.

    To answer your question, I've always had good luck with Avid RC, Acer, and VXB bearings. They all make 10x15x4 bearings, in rubber or metal shielded. If your bearings or shafts see alot of dust and dirt, which I'm sure they do, than go with a rubber seal. But the VXB metal shielded bearing S6700ZZ, is pretty darn stout.

    Here's a list of Avid RC 10x15x4 bearings, one or more of these, will definitely work for your Tekno shaft:

    Here's a link to an Acer rubber shielded 10x15x4 bearing:

    How many bearings do you get?

    Are you looking to replace every bearing in you truck, or just the wheel bearings?

    Yes and no, seen a few having problems with tekno like the pins on the dogbones snapping and chattering, and I have seen what somepeople put there MIPs through, and they always come out bulletproof.

    So MIP shafts it is x cvds that is. The x cvds only cost $10 more than the teknos

    You are not looking very hard if you think the MIPs are close to bulletproof. I see at least 5 threads related to problems with MIPs for each one related to Teknos. Then again, perhaps personal preference is influencing my perception?
    Either way, once set up properly, either choice should work well.

    So either option MIP x cvds Traxxas 1951R shafts, or the tekno shafts, if set up properly, they will all be great?? Opinions can throw us all for a loop, sorry if I am posting so many times about the topic driveshafts. It's just confusing what to make of it
    Sorry

    Tekno M6 CVD's problem...

    I emailed tekno and some photos. So we will wait and see if they give me new bearings. Hopefully. And just so i dont do this again. I will set it up differently this time.

    Here are pics
    Turns out both bearings exploded. And the stub axle pin was in two pieces.

    Sucks bro, same as what Spencer said, you really meant exploded. The problem that I heard with the Tekno is the pins breaking, not trying to advertise, but Airborn Bafoon on Youtube had the pin problem repeatedly on his Stampede 4x4 and had to get replacements through Tekno a lot, he just saved up for the MIPs and he has been fine, I hope you don't have the same problem as him and hope it will only be a one-time replacement.

    Failures for any part are not hard to find. Blaming a pin for not holding up to (ab)use that destroyed two bearings is not even close to reasonable. Neither would be blaming the MIP above for breaking due to crashing.

    Very true, when I have damaged a part due to a fault of my own, I don't ask for the warranty out of my principals. I had bent a flm bulkhead , driver error and just ordered a new one.
    Everything has its limits, nothing is invincible or bulletproof until proven or other wise...we ran at huge speeds , definitely at one point or the other like real cars some things will break .....regardless if it is metal, plastic or what not...

    So my other bearings exploded the other day. Not so happy with tekno. I think I'm just gonna get a bunch of the slash 4x4 rear halfshafts. Since they are cheap and are holding up pretty good so far

    That seems like a better plan
    Slash shafts are tough and cheap about $9 a pair) and last well, a while
