Putting new (spicer) ball joints in my jeep. Will be replacing the axles soon with a 60/9", just need to fix the busted axle and ball joints on my current axle so I can drive it in the meantime and then sell it to somebody without them having to do any repairs/maintenance to it. The new ball joints came with a brass sleeve (see picture). I'm assuming this is for some other application and I can 86 it?
