What is torque spec for drag link?

What is the torque spec for the factory drag link, I want to perform my own ďrecallĒ fix because Iíve seen some of the welding FCA has performed.

Iím going to be ordering a full thuren front kit later on this year but I do not want the dealer to perform this recall.

I’m not getting mine welded, I just keep an eye on the adjuster nuts. I’ve never found them loose, IMO it’s not worth loosing the ability to adjust the drag link over something I haven’t had an issue with. If I start finding mine loose I’ll weld it myself.

I was looking for that! Couldn’t seem to find that spec... not that I have a crows foot big enough to actually use a torque wrench on it.. I’ve always just made them extra extra snug.

You know what's the correct tool for the job?
I'm still trying to unsee the photo of two pipe wrenches being used.

Maybe if we start telling people that the brain is an app, they will start using it?

Pipe wrenches are for pipes. I can’t remember the size but I have some larger combo wrenches left over from my heavy equipment repair days that I used. Even a large adjustable would work. If I was going to torque to spec I would use a crows foot attached to a torque wrench, I just don’t have them up that large in my set.

I just went by feel on mine.

Something like this pic below, which was borrowed from google.

Adjustable wrenches are a not too distant second to pipe wrenches in my mind. A last resort, if you will.

But like you, I don't have a large enough crow foot to use the torque wrench. Luckily it's fairly easy to guesstimate the force needed to achieve about 100 ft.-lbs. with the size wrench needed.

Maybe if we start telling people that the brain is an app, they will start using it?

How in the world can Ram or anybody here make putting an end wrench on a nut and tightening it up so complicated? For 100 years there has was never "torque requirements" for anything other than head bolts and the like. You just tighten things up appropriately for their size and be done with it. If they need a lock washer or Loctite, so be it.
PS the offset length of a crow's foot would increase the leverage and thus the torque being applied by the torque wrench.
