Does it clunk when you turn like your axle is bad or going bad?I just replaced the ring on mine.Mine has 178,000 and no noises.But if you want to change it you have to pop it out of the trans.Take a bar and it put it between trans and flange on the axle shaft and pry out it should pop out.If you just change the tone ring I took a file and filed some of the rust off the diameter that the ring fits on new one slid on easily
