Default Knocking at passenger front

Only hear it at low speed 15 mph or less. It is not very loud, really have to listen to hear it. Might still do it above 15 mph but the engine noise could drown it out. Almost sounded like something in my glove box. Verified not the problem.
Any idea what to check. Only have a year to go on my extended warranty so want to take advantage of that if I can.

2011 LS sport

thanks

Ball joint? Mine did this same sort of noise, I only needed to have it re-torqued to spec and it was gone. Have you had the front control arms checked?

Have not had the control arms checked yet. But is that how the problem shows itself. Some kind of knocking?

My local dealer is not that great. So any info I have will help and let me know how much to push them to find a problem.

Thanks

​​​​​​​Yeah mine started to do that, it's pretty common for a lot of worn suspension components to kind of "clunk" when they get bad enough. Sway bar bushings are notorious for that too.

I noticed, on the way home, yesterday, my RF wheel makes a 'rattling' noise over Bott's dots. LF is still okay.

I'm at about 104K, so I see front-end bush work in the relatively-near future. Before I get new tires, certainly, and these shoes aren't going to make it more than another 5K miles, about.

I still say ball joint. Any shop can check it for you easily for play and wear.
