If the spindles were overheated due to a bearing malfunction then you will need to replace them or the axle. The spindles are already heat treated for strength but you will lose that strength if heated beyond a certain point after the fact. If there are any discolorations on the spindle (usually blueish) then that would indicate heat damage. If you can let me know what size axle you have and the shape I would be glad to see about getting you replacement spindles if applicable but most cases it's more cost effective to replace the axle unless you're a welder. I have attached both our replacement axle and spindle selection below.
