You might want to limit your articulation a bit. Calculate how much you currently have, then bring it down to at least 45 degrees. Bending that link may have been caused by binding the suspension I spoke of....High rise aluminum links ARE strong enough, if the chassis is set up right.
I would give you tips on the mods you want to make, but if parts are on the way, cool.

Chassis flex? If all the chassis screws are tight, you are not experiencing flex there, but a direct effect of too much articulation. Again, reduce your articulation, and the problem will disappear.

Your Axial, if it is stock, needs the upper links at the axle (which are mounted to a single point at the axle) to be mounted individually. Some buy four-link plates, some drill out holes in the front and rear servo plate, and mount each link to separate holes.

I myself, made a quasi-four link by attaching an aluminum shock rod end to the three link mount on the axle, and attaching the upper links to the shock rod end, so all four links move independently. That is the difference between the three and four link designs. Three links make the two upper links essentially one, and the axle, when articulating, rotates on that one pivot point, or axis, whereas four links have all four links moving along their respective planes of movement, and reduce what is known as "axle swing", which can cause the rig (chassis) to move in unwanted directions, as the suspension articulates.
Also, four links pretty much require you to reduce articulation, so see where I'm going with this?
