wishbone question

considering the idea of using a wishbone on my next project but it doesnt look like it gets enough triangulation.
i dont know that much about the geometry of the suspension but i know i need some sort of triangulation to keep the axle in place and it just doent seem like there is enough in this setup. am i missing something i know alot of folks use them, alot builders are using them so they smust be alright.
 
any ideas to what i might be missing here cause it sure would save alot headach not having to move a gas tank

A wishbone doesn't follow the same triangulation of a standard 4-link. If your bushings are far enough apart to control side to side movement, then your wishbone can take just about whatever shape you want.  

does it matter as to whether the single bushing side is on the frame or the axle?is there a prefernce as to which way works better

They both work the same way as far as centering the axle. They rely on the lower bars being there. On either style without the lower bars the axle could swing front to rear or side to side (depending on where the single pivot is), but once the lower bars are added into the equation you have a stable setup. Your single pivot determines where your roll center is, and the same rules apply to the 3-link and a 4-link when it comes to that, roughly.

ok i floow ya now. if it doesnt matter which side is which that will defiantely help out when time comes to install thanks seth i appreciate it
