09 tl sh awd has wobble after driving for a while

Hey. Im new here and new to the acura world. I have a 09 TL SH AWD. Had it for about 4 months and haven't had to do anything except maintenance but about a week ago on my way home from work it developed a wobble. Thought I was imagining it at first being as though I live in philly and the streets here are terrible but the next day on the way to work the wobble came back strong. Since then its continued but only after driving for some time. I have about a 30-40min commute to work and the wobble progressively gets worse after about 20min. Im pretty mechanically inclined so I took a look at her and noticed i had a bad upper ball joint on the passenger front so I replaced it along with an outter tie rod that had a ripped boot. That had zero affect. Drove to work the next day and experienced the same wobble. Im a chef and I have small children so I don't really have tons of free time on my hands so I had her towed to a local shop. Given the symptoms I guessed that it may be a wheel bearing and I asked the mechanic to take a look. Long story short he said my wheel bearings seem pretty new and he doesn't know what's wrong. He claimed he wasn't able to verify the symptoms I told him about. Was hoping you guys could maybe point me in the right direction. Anybody experienced the same? Any thoughts on what it could be?

Maybe check the lower control arm bushings on both sides, #8 & 9.
You don't mention the total miles on the car? Since the streets in philly are terrible, if the vehicle has the factory LCA's, these may be perished?
Search the OEM part numbers below to find aftermarket, like on rockauto, to save $$ over OEM if replaced.



Also check the lower ball joints as well?

Will do. It's somewhere around 156k on her. I went over the passenger side pretty good and replaced everything that seemed worn but I haven't gone over the driver side very well. I'll recheck the passenger side control arm and go over the driver side. The part that has me confused about the problem is that it seems to be related to how long I driver and not speed. I woukd think the LCA's would cause a problem that either revealed itself with speed or it would be a constant.
