About mods animation

Hello, I'm new making mods. I wanted to ask if someone can explain or point out a tutorial on how to animate the doors of a vehicle in the mudrunner and how to animate a suspension to lower and raise (similar to a lowrider, but I do not want to do a lowrider)

there are to ways, one if semi _cdt based suspension and the other is full _cdt colision axle suspension

both require a bit of knowledge about Spintires Moding

if your looking for a quick way to raise your suspension just add the _cdt and child your bone axle to that _cdt and code the controlled contraint to lift it (Use the Fuel cistern trailer as guide xml) and then troubleshoot any errors and MinLimit and MaxLimit are your Bottom and Top limits and Your Position in the contraint is where you want it to sit once activated
