Hi, my E-Revo makes an awful cracking noise , that I have found that comes from the shock rods , in the union to the rockers. It's not only the noise, it makes the suspension less sensible. This not happens when I shower the car, but at the moment it gets a little dust in it (in the first 30 secs) it makes this noise all the way. It doesn't matter if i lube it, it's worse because more dirt comes in.
- Do you have the same issue?
- Aluminium Shock rod ends could avoid this?

Also , I have a cracking noise in the rear half shafts when the car makes traction and twist them, also, when clean it doesn't do that.
- Traxxas CVD's also could be better?

I can reproduce the noise twisting one wheel with others blocked

Have u done any work on the supension? if so check that first. Then take your tires off and see what is binding. Does the front do it to? Does the supension rebound ok? if not maybe the pivetballs are to tight. Mine does that samething when it get really tirty. Let me know what happens Good luck

Now I have noticed that when is clean it also does the same noise, especially in the rear shock rod , also the shafts , where I localize the noise in the link near to the transmision.

The suspension has no mods, only blue and silver springs

that sounds terable....it does sound like something is to tight.....i would spray all the pivit balls with a lil wd40

I revised the tighten of all bolts, all seems ok. And If I oil them (did it before) , when its clean ok, but gets dirty in the first 10 seconds of ride and the noise is back.
Seems like the plastic rod don't rotate well with the metal hollow ball of the inside

its the bearing that sits in your rocker, that mounts on the rocker post, i think.

My Feedback: (3)

What chemicals are you using to clean? And do you run in wet conditions?
