As above fitting new hubs,and just pondered would nylocks be a better option against the old castellated ones ???

The old ones need a refresh so any links to either would be nice

Cheers

 

Yes you can use nylocs for the tca joint, but it may lock on tight enough to spin the joint bit that goes through the arm, but if you apply a little pressure from a jack undeneath this will stop it spinning so the nyloc can be tightened, if this doesn't work strip some wire and cut a few strand of copper wire and put in the hole before inserting the tca joint, this will hold it tight, allowing a nyloc to be used.
