This is where JKS control arms fail:







Eventually the internal threads will chew themselves up and strip out, leaving you with a sliding control arm that will allow the axle to shift front to rear on one side leading to very dangerous steering!

That doesn't look like a JKS arm. I see what looks like a urethane bushing at the axle end and JKS uses Clevite rubber.

Those aren't JKS arms. They're old Teraflex arms.

Thanks as well. How can I tell for sure? I'll ask a mod to change the threat title if theyre Teraflex.

That was on project Wrong Way. I've had several Jeeps since that one. These arms are on my newest Jeep, and are soon to be replaced with Savvy arms.

You can tell because the end ring is mounted offset to the tube on the one end. They're also thinner than the JKS arms. And Teraflex has no internal support bearing - that's why they wear out the adjuster threads from pivoting.

Here's a cutaway of a JKS arm:

Yep those look like the old POS Tera arms my previous TJ ran 12-13 years ago.

Maybe this is why my rig feels loose at the moment.

You guys are right, the lower control arms DO look like the Teraflex arms and not like the JKS arms.

Jerry, could you change the title for me so it says Teraflex instead of JKS?

Thanks!

Yeah, when I hit the gas the Jeep steers towards the curb, and when I let off the gas it steers into oncoming traffic...
