Tie Rod wrench sizes?

I am changing my outer tie rods and I don't have the right size wrench for the lock nut on the treaded end. Looks like a 21 MM. Anbody know what the size is and an easy way to break the nut loose? This things are really really tight. Thanks

I don't know about the size, but spray the nut /threads with PB Blaster, or your choice of penetrating oil, at least a day ahead of time.

I believe the two variants are 14 and 16mm and there is no way to tell which size you have without crawling underneath with a wrench.

That's for the threaded part of the tie rod end, not the OP's question. The lock nut is the same size for all model years I think, but I'm sorry I don't know exactly what size it is without looking. I'll go out and check it later because I also want to buy the proper wrench for the inner tie rod end while I'm at it. I've been using adjustables and that's not right.

My bad, I was reading off of my cell phone and didnt see that, sorry. I also do not know what size the lock nut is, but when you find out, please post back.

Should be 21mm, new ones are 22mm. Here's a good write-up:

Thanks

It's an easy job with a big enough wrench. I got a 12 inch adjustable from my neighbor and with my 10 inch adjustable wrench on the inner rod nut it finally broke loose. The rest was a piece of cake. A hammer or two on the knukle and one blow to the post screw and they popped right out.
