New nitro Rc's! Stampede and Maximum ST..pICs

[G Impala 63n70]

hey everyone, well i traded my nitro rustler and duratrax streetforce gp in for a Traxxas Stampede nitro and a Duratrax maximum ST. I got the good end of the deal but my stampede took a beating and is having problems, today as i was driving it for the first time i noticed the steering sticks and ihave to snap the wheels straight for it to work again and it keeps doing it, so i took the servo conncection off and the servo is fine with no load on it. i think theres something wrong with the white thing the tie rods connect to. And then i kinda ignored that problem and was having fun until it started revving but not going anywhere so i look at it and one of the rear axles i think broke, there is a lil metal pin inside and it bent, how the hell do i replace that and what can i do to prevent it, i wasnt even bashing...i know theres alot of things rigged on both cars, including the custom bodies im making fit cuz it didnt come wit any. so let it slide for now and ill fix them up. let me know what u think and any help would be great! id like to get these things rollin!
also, on the Maximus ST the rear wheels wiggle so much it affects the cars ride and steering and is overall not good, is this beucase the truck is very old n outdated or is something wrong? also id like to add its impossible to tighten the motor mounts on these things lol. alright guys im out heres pics

Have you seen the new twinzilla truck? It has two 26 nitro engines 7 inch tall tires, any bigger you could ride it.

wow r u serious? i dont even get the point of the truckzilla or twin titan, ive ran 2 twin motor trucks before and the only thing is that impressive is the torque and how they can like pull out tree stumps, but i dont really think they are all that cool, a local hobby shop owner around here has a twin .70 titan, and its not even al that fast to be honest. does wheelies though. the .70 is by far the biggest ive seen, i dont think they make a bigger one.
