Clean bolt threads. Try either 243 Loctite (med strength) or 277 Loctite (high strength). And torque to specification.

Two totally different compounds. Both high temp and high strength yes, but 277 is suprieror in shock loading and vibration properties.

Not sure the price difference between genuine and bolt manufacturer prices, but quote around. Throw the crown nuts away too and go nyloc. Much more shear and tensile strength.

I used genuine ones about 6 dollars for the set. I don't think that there are classed as one use, but I have mine in and out a lot so it is just safer to replace them. I replace mine every second time these days.

the nuts are a large outside diameter so that they lock into a bit of a recess in the back of the universal. Can you even get nyloc nuts with the correct outside diameter? I think original might be the only option for replacement
