Replace everything on the front at one time. Parts are cheap.
I don't think you have to remove the spindle, but I might be wrong. It has been almost 20 years since I did this.
The back bushings are fairly easy. It is the back bearings that are a ROYAL BEAR! Tapered fit that does NOT want to come apart.
See if you can find the repair manual from Robert Bentley. Best one there is. It is basically a reprint of the factory manual. Only issue I had with it was the mention of all the special tools, which for me usually wound up being a 2 pound hammer.
