If you're going to a different gear ratio yes.

I think Paul answered that question in Post #3. If the gear ratio remains the same, then no you do not need to replace the ring and pinion in the front. Unless of course the front has some other issue as well.

Why are you replacing the rear gears?

Sounds bad. You should inspect the front to see if someone "chewed" that up as well. Most likely okay, but better to find out now.

If you change the RATIO, you should match front and rear, i.e: you had 3.55 (that would be on both axles), if you change the rear to a 4.10 ratio, the front should be matched to that 4.10 ratio also.

Most likely 3.55s. Aren't yoou planning a big lift and stuff too?

If so, now is the perfect time to swap to lower gears. Pick a tire size, than match your gears to that.
