After changing the wheel hub bearing; I can;t get the castle nut to go back on the castle nut screw. It continues to turn. I know the tie rod end might be bad, but i don't want a new tie rod end. How can I get this castle nut back on. Oh yeah, please let the automotive community that this is a common problem and very rarely, if ever, addressed. Thanks, Bill

It sounds like the end of the tie-rod end's taper pin with the screwthreads is mushroomed on the end and the nut won't go on. It's probably because someone hammered on it or used a puller too aggressively. If so, I'd use a grinder to clean up the end of the pin and use thread repair tools to fix the threads if necessary.
