Does anyone know how to remove the steering U Joint that's right above the rack? Or do you know how much time it would take an indy to replace it?

unless you know it is totally shot, try spraying the heck out of it with PB blaster (or the like) and turn the steering back and forth till it loosens up, while the front end is on jacks. Mine got stiff at about 300k miles and the dealer wanted something like $150 to replace it. After my PB Blaster treatment, it's been turning smoothly to this day (over a year ago)
Good luck

you can get access to it under the dash. there is a rubber seal and plae around the steering shaft. undo the top bolt then pull the steering wheel lock lever and pull the wheel out, now lift up on the round plate with a srewdriver and pull the rubber seal off to, now just undo the bottom bolt and yank it off.
u probably will have to use a long srewdriver and pound it off with a hammer from underneath
