For those that have done the install, how difficult is it? Getting ready to order one and contemplating if I should do it myself. I am no mechanic by any means, but I guess you could say I'm a weekend warrior mechanic (oil changes, tune ups, brakes, etc.) I've called around locally to get a few estimates, and all are around $175-$200 range. I think I can do the job and just buy a few tools that I may need. Can I do the job with the car on rhino ramps? I know I'll need a good torque wrench. Any info is appreciated.
