Trying to track down knocking in steering. (with video)

I've got just over 102k on my commander and there's a bit of front end noise both going over bumps and when the steering wheel is in a certain spot. I have inspected the front differential bushings and they are good.

I have a feeling I'm in for a new set of LCAs for sure. Anyway, when I remove the driver tie rod knock is still present. When I remove the passenger tie rod, the knock is gone. From inside the car the sound translates to the floor under the driver feet.

I'm guessing I should replace the LCAs and then move to the tie rods if this persists?

I'm really hoping this isn't a rack issue.

Video is passenger side.

Have you replaced the bushing in the anti sway bar?

No, I was planning to do that when I did the LCAs

I would do it first. Easy/cheap fix and a common noise on our XKs

Yeah, I though about that and said to myself it couldn't be that easy.

I'll get a new set and report back.

Not sure if this is your problem, but something to try at least. Someone else posted about this here a long time ago, but I couldn't find it here. Similar thread found on another forum: https://www.theultimatejeep.com/show...-popping-noise)

Good luck.

Replaced the sway bar links and re-torqued everything. The knocking over bumps is gone but, the steering clunk is still present. It only makes the clunk when turning right and only one time until I turn right again.

After work today I removed the oil drip tray and tightened the steering rack mesh bolt about a 1/3 turn. Reinstalled the oil drip pan and test drove the Jeep.

Problem solved, thanks for all the tips and help tracking this down.
