Traxxas Cvd Problems ...
Posted 18 June 2011 - 12:01 AM
While I had it down to replace the cup, I decided I wanted to convert it to a Summit so I got the blue springs and the long rockers. Got it all back together and less than a week later, the front CVD fell out of the cup. Nope, nothing was broke, just flat fell out ...
Knowing the Summit has differant part numbers for the axle driveshafts, I thought the CVD's were too short so I put the Revo rockers back on (running front rockers on front & rear).
Within 2 weeks, the rear CVD on the opposite side of the one that broke the cup has fallen out ...
Why are these falling out all of a sudden?
Are the Revo CVD's too short to run in the Summit? I'd really like to convert it to a Summit ...
Will the stock Revo axles (plastic sliding ones) work in the Summit? All 4 (4 inner & 4 outer) are $80 ($9.99 ea) so if the stock Revo axles will work I'll get those instead ... I'm only running 2s on a stock motor/esc.
What's going on with my CVD's all of a sudden ...

Once I get my MERV (This Tuesday! YAY!) I will be taking it with me next time I go to my Dad's... he is a machinist. I will ask if he has any ideas on how to make a strong, trouble free, durable replacement axle shaft....
I just hope he can keep costs reasonable. lol
Either way, I will have him make some for me, then ask him how much he will charge to make more and go from there. I know he won't make a bunch just to sit on a shelf, waiting to be sold; but I might convince him to make them to order.

I have been really disappointed with the quality/durability (or lack there of) of the aftermarket axles... especially for the cost.
I don't know if you'd classify these CVD's I have as aftermarket or not. They're not stock but they are made by Traxxas.
I can give a bit of insight on the good and bad products I've used on mine. I'm neither bashing nor endorsing these companies. Just stating facts on the stuff I've used. Note: I'm just a basher & I run the stock motor/esc on a single 2s lipo. So, it's not like I put excessive power to parts. You can go through my build thread here if you wish:
Center Driveshafts (from trans to the diffs) - I've used both Integy and Golden Horizon. Pin broke on both. When the Integy broke (short front one), it put a gash in my chassis almost cutting the front end off. Put new pin in the Integy and then shrink wrapped the ends (so they wouldn't fall out ... ) Being nice, let's just say I went back to the stock driveshafts ...
Stock chassis - broken 2 so far. The second one was 2 weeks after I replaced the first one. The way it broke and what heppened when it did break, IMO was uncalled for ...
GPM knuckle hubs - Love em, never had a bit of trouble with them !!!
GPM pushrod/toe links - I intended to get the stasinless ones but ordered the aluminum ones by accident. Yeah, these bent pretty easily. Ordered the stainless ones, not a problem since.
All my other upgrades have performed as expected.

it would be ideal if there was a slip shaft, but there isn't.... and the stock summit rear axles are worse than the stock plastic merv axles.....
