So I remember years back when a diff bushing or a LCA / UCA bushing went bad you could either get a new component from Cadillac which has these bushings in it or opt for more expensive after-market options
which of course offer better quality and durability. I myself a couple of years back replaced my rear diff bushing with a better quality urethane bushing and my rear UCA bushings with urethane ones as well.
But when you need to do a lot of these it can get pricey. And some of these bushings like knuckle bushings for example are either mostly not available at all in the aftermarket or you have to dig deep to find them.
Over time certain parts started to become available either from Cadillac or through other manufacturers that match OEM quality, this is good news for those just looking for an OEM replacement at a relatively cheaper cost than aftermarket.
I thought I compile a list here for those who have been struggling to find this info just for general public benefit.
GM Rear Differential Sleeved Bushing:
GM Part# 89058605
MSRP: $21.33, online retailer pricing example GM Parts Direct $13.01
Febest seems to be a manufacturer that makes plenty of OEM like bushings for the CTS's suspension who knows they might be the OEM itself, here's a picture that shows the Febest part numbers .
I found a seller on eBay which sells these and there are others as well with same of different prices I will post the price I fount from this seller (thefinestautoparts is the seller name)
Note the front UCA housing bushing part# is CDSS-CTSF however I have not been able to find this part for sale anywhere so I had to make due with a used upper control housing, I did not try contacting Febest to see if it's for sale.
Front Suspension:
Front Lower Control Febest Part# CDAB-001 eBay price $14.02 (Bushing facing the front of the car)
Front Lower Control Febest Part# CDAB-002 eBay price $20.22 (Bushing facing the rear of the car)

Rear Trailing Arm Bushing at Knuckle Febest Part # CDAB-020 - eBay price $11.56
I find the rear bushing knuckles most interesting, as these are not available from the aftermarket and I'm not aware of a way to get them from Cadillac except through buying a new knuckle.
And a new rear knuckle is quiet pricey think $225 at places like GM Parts direct, left rear knuckle part# 88951999, right rear knuckle part# 88952000.
Also this one is well known by now but just putting it for reference:
