First there is a smile on your face because you are doing something fun then there is a bang followed by a series of bangs/clunks/grinding. You stop, get out of your Jeep and after some investigation you figure out you have broken spider gears. These specimens are from a Jeep Wrangler TJ.
Of course a spool or quality locker might not result in this but there you are. What a better excuse for an upgrade.
Consider an ARB Air Locker or a Detroit. If you broke spiders a Lock Right style locker is probably not a good choice.
