Default 2007 ES350 oil leak

I have a 2007 Lexus ES350. I peaked under my car recently and noticed a bit of oil underneath one of my boots in the passenger side (oil leak #1 in the attachment). There is also small slight oil leak coming from below the serpentine belt (oil leak #2 in the attachment).

In regard to the oil leak #1 in the boot, is that a rack and pinion or the right axle? Is the boot repairable or do I need to replace the whole shaft?

Not sure about oil leak #2 from behind the engine. Anyone know what it is?

Both appear to be due to a leaking CV axle boot clamp.. on the inner boot. You can see grease flung around on the sway bar and where your #1 arrow is pointing. If the grease got onto the power steering rack boot, which is what that is, and look like a leak. Its also possible that you have a leaking power steering rack. It would be best to get the car on a rack, so you can inspect further, clean up the mess, and monitor the leaks.

The rack & pinion is definitely leaking. Common problem.

The fluid near the CV boot could also be oil leaking from the timing cover seal. That's also quite common.

I thought the 07's had electronic steering, not hydraukic

Thanks guys for looking into this. If the rack and pinion is causing the issue, does that explain why when I am going 70-80mph downhill my steering wheel would shake?
Is this a big job to replace the rack and pinion or is it fixable?

I think mine has hydraulic since I have power steering fluid here. It doesn't seem to be leaking from that though.
