Theres a reason I Like to do my own oil changes.
My most recent oil change- 98,327 (3/2021)
While youre doing the work you make a little inspection of the undercarriage.
Thats when I found gear lube flung all over the wheel well.
Upon closed inspection something had knicked the CV axle boot.
The CV axle was quiet. No noise.
I pondered replacing the boot only. Cost of boot and work and mess to do it.
Or just get a new CV axle.
Since I was going to replace many major components of the suspension- I decided to replace with a new one.
Ordered all the suspension pieces.
Removing it was fairly easy. Tapping it with a long screwdriver and hammer it slid out. (CA- no rust)
Put the new one in- and that was it. I also replaced control arms and struts.
But the nice thing about it- was that removing the parts-- gave me great access to 2 of the harder to get to Oxygen sensors on the V6... PLUS PLUS- WIN.

the last picture- you can see knicks- on the 1st 3 'ribs' from whatever hit it on the road.

lower control arm out of the way.
CV axle out of the way.
sway bar end links out of the way
brake/rotor etc out of the way...
I also had removed the sway bar bushings (they too were replaced).

crowsfoot, extensions, and a breaker bar---
this O2 sensor was (now) a breeze.
You can see where the CV axle connects.

but wait--- theres more!!!
the upper O2 sensor.

With a hint from a thread on here...
I undid the lower PS connector- on the PS pump. the connector was rubber hose to a metal tube. The tube was in the way of the breaker bar. I could have loosened the O2 sensor but when putting your weight into it--I could have bent the hell out of that connector. So I undid it- You can see I a little piece of white paper towel stuffed into the hole- to slow the PS fluid drips.
Once that was out if the way- the breaker bar extended far enough- and me on my back... grab on and pull.... for those that have done O2 sensors---- you know they make that very distinct CRACK when they break loose.
But the harder part was the effn plug for the sensor.

Let us know if your mpg improves with the new O2 sensors. I got 2 mpg back changing the ones in my thirsty Tahoe.

That undercarriage is spotless other than the lube all over the place. Must be nice not living in a snow belt!

@rbarrios : That CV boot damage ... is that two punctures that are bridged in between? If so, how does that kind of damage occur on a boot spinning at such a high rate of speed?

Could that have been caused by something hot on the *inside” that melted its way through? The holes look kind of mushroomed - like the rubber melted and cooled off.

yes 2 punctures.
If you look at the other 2 pleats? they show damage- like something rubbed against them.

i cleaned up all that grease.
a little bit of simple green.....

rear- new shock and wipe a little of the lower arm.
then wipe some metal pieces.
