Seized Jam nut on tie rod / track rod end

[Monty101]

Hi

I’ve recently had my car tracking done but the jam nut was seized on the tie-rod, the mechanic used a blow lamp to heat the nut, then when he started to turn it he gave it a squirt of WD40

It did the trick, but would this have damaged or hardened / embrittle the tie-rod with the WD40 cooling the metal too quickly?

will this cause the tie-rod to fail?

I can change a tie rod end, but I don’t have the tools to do a tie rod

its fine , half the used cars on the road have had this done

Thank you,

It just got me anxious as I remember many years ago when I did engineering that heating and cooling metal quickly could make it hard and brittle

I thought the WD might have cooled it to quickly
