Your 2007 SRX has shock absorbers.
You would have a ride select knob if you had magnetic ride.
Soft ride or sport shocks are available at RockAuto. Amazon and eBay are sold out, and they ain't cheap!
There's a TRW on closeout I would have purchased myself but they only had one left.
One of my shocks would have to be leaking oil and the truck would have to be bouncing all over the place before I would spend that kind of money, but I only have 84,000 miles on my 2008 SRX.

 

What kind of Shock Absorbers can I use? Looks like Front Suspension Struts & Mounts Kit KYB Gas-a-just For Cadillac SRX 2004-2009 are available on eBay for $300... But that doesn't solve the rear end.

Are they the same in the front and rear? It appears the front and back are different...

Also, looks like I will have to reuse the springs and everything else other than the strut itself?

 

1st you need to look in the compartment in the back on the right hand side above your subwoofer at your RPO code sticker and see if you have the FE1 or FE3 suspension.
FE1 is the normal most common soft ride suspension that went into a huge percentage of these cars. FE3 is the Sport Suspension pkg.
Then choose from These

Thank you for the RockAuto link🙏!
Where is the subwoofer and the rear compartment you're talking about? I assume the FE3 is magnetic option that would require the ride selection dial?

 

PS The difference between a shock absorber and a strut is, a strut helps support the weight of the vehicle, whereas the shock merely dampens the shock of the road surfaces.
No spring, it's a shock.

 

Ok, thanks for the clarification. The existing strut has a spring. Should it have a spring, or did someone put on the wrong thing?

Also, what is a RPO code?

 

GM doesn't make it easy and Cadillac even offered rough road packages, but FE1, FE3 and F55 are the suspension codes you need to look for.

 

An RPO code label has a breakdown of every package or option your car has. The codes are in semi alphabetical order and the label is two tone silver and black most of the time and that's what you're looking for in that compartment in the back of the car.
It looks like this:

 

The sticker is not in that rear compartment. Any other suggestions as to where it could be located?

 

Hello fellow Cadillac enthusiasts!

If you buy a Dodge Caravan you can bank on it coming with the cheapest struts and shocks they could buy, but that's not what you've got on your Cadillac!

I never asked what the mileage was on your SRX, but...
My advice, if it ain't broke don't try to fix it.

 

You have no choices for the front shocks. ACDelco 540-598
For the rear you need to check your codes for the tire size codes shown on the rear FE1 listings.

 

I'm not sure it's necessary to remove those, but I would only replace them if they were torn or rotten.
Here's an instructional video some guy put on YouTube that is replacing shocks on a 2004 SRX, which is exactly the same as yours, and yes you need special tools.
The spring must be compressed so the shock can be removed from the "strut" assembly which is an integral part of the car.
I'm heading to bed, good luck.
SRX Shock Replacement

 

THE ONLY MATCHED SET AVAILABLE:
*AC DELCO 5801037 x2 REAR
*AC DELCO 580438 x2 FRONT
IS CORRECT ACCORDING TO THE RPO CODES

Alternate Brands and Numbers
ARNOTT MR3441 x2 FRONT
CARDONE 4J0007S x2 REAR

*KYB SM5845 x2 STRUT MOUNT < necessary to do the job right
DORMAN 523220 x2 STRUT MOUNT < costs twice as much as the KYB but it's not superior.

Some convert their suspension to the base model components to save money and to reduce headaches.
There are more shock and strut options available to me because I have the soft ride suspension.

GOOGLE each part number for the best price and availability on Ebay or Amazon, or order them all from *RockAuto because everything listed above is in stock.

 

How do I know the replacement shocks are the FE3 as opposed to FE1?

 

It appears you have three choices.
You can either buy the parts your RPO sticker indicates your car needs, remove the parts and cross reference the part #s if you can't see them without removal, or take it to a shop and let them figure it out. I agree with the sage advice above. I think it would be wise if you pay someone with experience to swap out the front shocks in the strut assembly.

 

A question was asked earlier about how to separate the springs from the struts. Do NOT use what is commonly sold as spring compressors. Very dangerous. Find a shop that has a wall mounted strut compressor. Many shops have seen parts of the strut assembly bounce off of walls and some have been killed if improperly disassembled. The first time I did it , I paid the shop to break them down for me. After that, I felt comfortable doing it but only with a wall mounted strut compressor. Good Luck
