On my ex W124 300D when i put a tie rod end on , one of the nuts at the center link wouldn't get any tighter after a while. I was holding the the end with an allen and it just kept spinning and spinning. I didn't overtorque it. Looking at it its about the same place on the shaft as the other tight nuts on the tie rods . But i'm a little worried about it since they don't have cotter pins in these.

Do you think that nut could come off and the tie rod pop out?

I thought there was a slight chance it could so i took some precautions. It was late sunday and cold and i was ready to be done and take it to the alignment and didn't want to get a new tierod end just for this. So i boogered up the remaining threads under the nut so it couldn't back off. I drove car for a couple weeks like that and checked and nut hadn't backed off any.

This weekend when i sold the car i told the owner about it and said we may need to do more to keep it from coming off. I also put silicone RTV all over it to hopefully hold it.

So how would you ensure that thing doesn't come off? A little weld? Would JB Weld do it? Or do you think its fine?

Thanks
