So I've been into sportscars all my life. Always liked trucks starting when I was a kid watching The Fall Guy! Anyhow, now that I'm about to get a real rig I have some basic questions I've always wondered... Firgured you 80'ers can help me: 1. Why is live axle always designed with one shock going each direction? On old school RC cars the live rear axle shocks go one direction for example. Does this act as some sort of stabilizer? 2. What is that cross brace looking thing I often see on a beefed up suspension like many of you have? It seems to attach to the live axle in some way. 3. What is the horizontal shock I sometimes see also somewhere near that brace on a live axle? Some sort of bump steer tamper? Do axles have mounting brackets or is it some sort of self contained stabilizer bar? 4. Those super heavy duty looking bumpers that wenches are often mounted on... They look like thery're made of iron. Have they even outlasted the car its anchored to because the chassis is weaker link? Also, do they actually help reduce crumple in a crash? Any diagrams or links you can point me would be great too. Thanks in advance!
