Steering/Front Drivetrain Thud/Snap

When I steer all the way left or right I hear a metallic thud or snap. It seems to be coming from my passenger side CV joint/wheel area. I don't hear it when turning all the way left but on the return it occurs. This sound occurs both when I'm turning all the way right almost towards the end of the travel and on the return. I've recently replaced my steering box, drop arm, and tightened both wheel bearings. I was told to remove my steering damper and see if that made the sound go away and it did not. Can anyone tell me if this sounds like a CV joint issue/failure? Thanks.

Lots of options... Was the truck standing still or driving?

The car was moving. I believe the passenger front tire got hit straight on in an accident I had a month or so ago, I haven't done much driving since then. Could that have possibly damaged the CV joint?

Doesn't happen when you are rolling or only when you turn the wheel to lock?

When a CV starts to go bad you will usually hear a loud clicking when turning hard. Off road it is much more intense with varying degrees of destruction. If you have checked the bearings and they are good it might be time to pull the hub and look at the CV.

I've got the CV joint out right now, is there anything I should look for to tell if it is bad/worn? Everything appears fine to me.

No unusual sound when rolling, just a clunk or thud when turning all the way left or right. Only happens when I've turned the wheel almost to lock.

Worn CV joint will have play on its central axis. Push/pull you should feel very little slop.

If it only does it at lock and not rolling, id not be as worried about the CV's. How's are the ball joints and steering box.

Just installed a newly remanufactured steering box from Meridan according to LR workshop manual instructions and a new drop/pitman arm. I've replaced every tie rod end and sway bar bushing with new ones.

Slightly loose panhard rod bolt where it mounts to the differential.
