Krawler Joint to Johhny Joint(Pics) - North American Grand Cherokee Association

williamj · 03-12-2007, 04:42 AM

Alright folks, This weekend I replaced the two frame side Krawler Joints on my RK Front lowers. It is a simple swap, and I did not have to cut the shank eventhough they are ~1.5" longer. They threaded all the way into the bottom of the control arm and fit perfectly.

I used 1" forged shank 2.5" Johnny Joints with 14TPI(threads per inch) right hand thread. They can be purchased through JKS and Currie and I am sure other places. Now for the pics.

As you can see there is a substantial difference in size.

They have a lot better ride then the Krawler Joints did and I am completely Satisfied. You may have to make your uppers slightly longer since the Johhny Joint increases the length slightly.

Just what I wanted to hear...Looks like a nice knee replacement for your rig. I want to do this on my LA's very soon.

Did you order them from Currie and did you have to add any spacers to get them to fit correctly? (width)?

I actually got them through JKS. It was as simple as unscrewing the old Krawler Joint(the hard part), and just screwing in the Johnny joint. Piece of cake.

Is this the joint you used? (2nd from bottom)

I may need to order a full set. I just need to make sure they will work on the LA body mounts RK makes. If not, I guess I could build some spacers. I will have to take some measurements when I get a chance.

Those are the ones that I used. You could call RK and find out if the Long arms use a 1" shank. Just be careful b/c my uppers use a 3/4" shank instead of the 1". If you have the arms already it should be fairly obvious. Just measure across the hole.

When I got the jeep I attempted to, but most of them were broken off. I couldn't get the grease gun on the ones that were there, b/c the jam nut got in the way of the grease gun tip since the zerk is angled right at the jam nut. I would assume that the salt from the roads didn't help matters any.

I actually broke one of the zerks last time I greased mine. You can only get a little bit in anyways.

Those look beefy as [smilie=censored.gif] ! I wouldn't mind swapping mine over. What did they run you each. JKS didn't have it listed on their site. Atleast with the link listed above.

There about $37 each for the joint and $2 for the jam nut.
