Thanks for the info VW! I was really wondering if the axis ever met. After further reading and understanding of ball type cv joints, I have decided to not peruse using a standard cv joint because of backlash issues associated. Possible solution aside from the offset axis is to use another type of constant velocity joint like this design from Martin Gecík on YouTube

Hi Jeff and others, I have been playing with the idea of utilizing a constant velocity joint in the steering system. After reading papers on commercially developed constant steering joints I found that this has already been explored. However I have not been able to find a vehicle in production that has a CSJ. I was going to give up but then I found a company who makes CV joints and started a conversation about what it would take to make my own. This system should simplify the steering routing by only using one joint and also eliminate torque fluctuation. The rep I spoke with tells me this joint has been used for steering application in the past with success. I just need some input to see if this thing can fly. Jeff what I need to know is: The degrees between the steering column shaft and the rack and pinion input shaft if their lengths were to meet The distance from the rack's input shaft and the vertex where it would meet the steering column. Clearance at the vertex (the joint i am considering has a 75mm outer diameter) Cost of the joint without machining is about $100 What do you guys think?
