ok fellow jeepers so I have a big paycheck coming and I was able to make sure that it all goes towards my jeep I have around 400 bucks but I have to buy rear axle bearings and a tensioner pulley bearing so I was looking for opinions on what to do with the remainder around 320 dollars I was thinking about putting a locker in my rear end since I will already have it open for service.

what are your opinions on upgrades?
