The part of my headphone jack that transmits to the right earphone went bad and it was really annoying. So I ordered a new jack and went ahead with a new battery as well.
The repair went great only took about 15 minutes total, about 5 to get it open. I didn't use putty knife though I just used the tools that came with the battey and used the metal spudger to unset the clips with very minimal damage to the casing there is just a minute gap on the right side but I can live with that.
Opening the device is the hardest part so just be very gentle with it but thanks to the repair guide i can enjoy my iPod again.
