With grease in them, good luck getting a solid weld that seals the caps. Every manufacturer out there says that heat should never be used on a spindle, and they shouldn't be welded on. That said, done correctly it shouldn't be an issue, but the my first point makes going that route kind of a moot point. Get your part number and shop around. Frontier truck parts has a lot of new takeoff parts for a fraction of the cost of new, but the shop owes you a new spindle anyway - even from the dealer, they're not that expensive - $1-1.5k a side most likely.
