Hello, I've been reading the theory behind power steering systems on: http://auto.howstuffworks.com/steering.htm And cross referencing that with my Bently manual, trying to figure out what applies to my 1988 Vanagon camper. Most of it makes sense, but left me wondering how the tortion bar connects to the steering column. When placing a constant ammount of torque on the steering wheel, it goes through several revolutions before reaching the stop. But the tortion bar should only flex a constant amount to allow the power steering fluid to pass through the rotary valve and on to the rack. What is the mechanism that allows the steering wheel to complete several rotations while flexing the tortion bar a constant ammount? My rusty, metal power steering pressure line recently cracked, which is why I'm so interested in this stuff. I'll be replacing the pressure and return lines next weekend with hoses from Frank Condelli's shop: http://members.aol.com/Fkc43/hose.htm Thanks, Matt |
