The rack is easy to rebuild but it requires a complete disassembly. You can easily remove the old rack bushing once the shaft is out. Use an extra long breaker bar with a socket on the end and tap the bushing out with a hammer or use a length of pipe and tap accordingly.
I highly recommend rebuilding using Rodney Dickmans steering rack bushing. The fit is perfect and there is no slop what-so-ever.
