I have a 2009 Tahoe. When I go over a speed bump straight on with both front tires, it squeaks in the front. But, when I go over the speed bump with either the driver OR the passenger front tire only, no squeak. Any ideas what might be squeaking? I bought some lithium spray grease but didn’t want to start putting it on everything just guessing.

I hear that, the same way, sometimes on my Tahoe. But I also have poly bushings with Hellwig bars, front and rear. I spray them and the noise goes away. You could have nothing but rubber but get the noise because of being real dry where you are or salt problems or or or......Spray away.
Have someone bounce the front end up and down while you're under it (with clearance, of course) to pinpoint the cause. Likely a sway bar link bushing or the sway bar frame mount bushing, but could be something else. Loose shock/strut, control arm bushing, etc. when the suspension is flexed a lot.
Way out there: check the engine and transmission mounts for looseness.

no zirk and spray on the outside probably won't get in where it needs it.
I unbolted mine and greased all the bushinga by hand. it's a crazy thick sticky grease I just happenened to have extra packets of.
you might just replace them all for the heck of it. the part numbers are on here somewhere. I think @mikez71 did his a little while back.

They are cheap.. If they look crappy, just replace them. Just use OE replacements
from local parts store (can use store brand no issues)
I used Sil-glyde on mine when I replaced the bushings and end links.
The same here when I did the Hellwig bars.
best thing to do is unbolt the D bushings and slop some grease in there, you will want to do this seasonally and it might still squeak anyway, if you want zerks there expensive
for these fancy ones anyway

Our vehicles are due for front suspension refresh due to age. Bushings, bearings, shocks and seals. Fortunately the suspension components with new bushings are cheaper than extracting the bushes themselves and replacing them.
Start shopping for upper and lower control arms, tie rod ends and poly sway bar bushings on RockAuto after you lube up your bushings.
By the time the lube stops working you can drop off the truck with the parts and ride better than new for another decade and a half.
