Default Steering knuckle failure

I'm sure it's a common issue...
and yeah, I know alloy steering knuckles are available...

But I'm not ponying up for that, at this time.

would seem the knuckle's break at the 2nd inner hole
on the knuckle's steering arm...

Has anyone figure out what might work to strengthen
that arm at the inner hole ?

I thought that maybe filling that hole
with a CA glue or even maybe a screw...
might reduce the chance of breaking at that hole on the arm...

anyone use a method that might strengthen that arm ?

guess something has to give...
and knuckle's are cheaper then a damaged servo.

btw... I didn't even hit anything...
was just rolling along... and fubar ! ?

Upgrade them. When something else breaks, then upgrade it. Eventually your rig will be bulletproof.

If your servo breaks because of aluminum knuckles, then the servo was too cheap to begin with. I made my rig bulletproof before I ever started driving it.

with the power we are running now I would recommend to bite the bullet. I have never ran a stock C or knuckle. I go straight to vanquish and forget about it. The piece of mind knowing that you can pull a line or a buddy without breaking is a priceless. Go to the for sale section. Guys post these upgrades up there almost everyday for very good prices.

I agree with bananaclip, if you said you broke it just rolling down a hill, just imagine how they perform when you get in a jam while rock crawling, you wont be able to turn the wheels because the plastic will be bending back and forth.

If you go for longer hikes/trail rides, it would suck to have a cheapo plastic part ruin your day, better to spend $40 and not worry about it breaking on the trail. I would also recommend the vanquish parts.

The stock knuckles are really really weak and except for the absolute easiest trail rides (think smooth dirt road lol) they WILL simply let you down. Spend the $30-$40 and get some aluminum knuckles and it'll never be a problem again.

How about a short screw threaded into the hole with washers on either side and a locknut?

Aluminum arms are much stronger than plastic...but, nothing is indestructible. I've broken aluminum arms as well.

I tried to make a metal bracket to strengthen mine. It still failed. So I got the Ally Knuckles...and now the C-hubs flex instead! Hehe.
