91 pathfinder tie rod castle nut size

[bingomech]

Hi there board members, I am about to change my tie rod ends on my 91 pathfinder. I cant find the size of the castle nut under the joint anywhere in my chilton or haynes repair manuals. Can someone please tell me the correct size of the nut. I have socket and hand wrenches up to 19mm but i think its bigger that that.

Also i saw a how to video on U tube after removing the castle nut the guy gave the fitting a couple of whacks with a small sledge hammer to release the ball joint from the arm for relacement . Has anyone tried that? Or should i buy a tie rod end puller. Guys any advise is appreciated here.

 

 

Thanks

I'll check the size for you in a few hours when I'm outside and it isn't freezing.

 

As for banging on the end, that can work but you can damage the thread if you aren't careful. A trick is to leave the nut on, flush with the end of the threads to protect them. Also, the joint may not be perfectly rigid and it might be hard to break the taper loose with it flexing every time you hit it. If you can borrow or buy a pickle fork

 

It is the way to go, the wedge drives them apart nicely.

 

I'll move this to the 1990-1995 WD21 section for better visibility. Welcome to NPORA BTW...

Agreed. A fork would be a nice thing to have when doing thse sort of things. IIRC they are not expensive.

7/8" (22 or 23mm).

The castle nuts on my tie rod ends (3) are 17mm.

I do have one with a nylon lock nut that is larger, maybe 21mm. Maybe that is that Kingman is thinking of.

The fork tool, tie rod removal tool was $9.25 at AutoZone and works like a charm. Money well spent.

Thanks for the info guys . Im changing some parts on the steering system (tie rods),(cross rod or drag arm) and idler arm. I have slight side to side movement on my right or passenger side wheel, i suspect its one of the right cross rod balljoint. Butt here is no way to know unless i remove it and check i guess. Also thanks to jim for the how to movie on the swaybar bushings replacement.That will be the next project in line.
