Fixing spinning reels??

[Esox Luciano]

I've had a few problems with a few reels in the past and every problem on each reel I had to fix I make feasible until I run into the only problem that stops me...The axle. It's the bolt that comes out of the reel and holds the spool in place. The drag still works perfect via the cap on top of the spool, but the axle won't reciprocate up and down to evenly distribute the line onto the spool. 2 out of 3 of the reels will kind of lock up after about 2 turns. Now I have 3 reels that are in purgatory until I can make a decision. Any suggestions or info for diy options or should I scrap em? Thanks for any info guys!!
