The power steering pump and oil filter housing gasket are pretty easy DIY's. And pretty cheap at that. Not to mention that replacing the power steering pump automatically gives you access to the oil filter housing so it should save a step in the repair process (and reduce the labor cost to replace the gasket).
Brake jobs are basic DIY's. Radiator replacement, also DIY (but do you really need that right now?). Brake fluid flush... DIY.
Search the forum. I am sure you will find a DIY for each of the items listed. If not, we are happy to help you figure it out.
IMHO, If a car has more than 50K miles, you only treat if there are symptoms as cost of repair beats the purpose as car is going to age any way.
So, do you have any problems with the truck? at 125,000 miles, I think you should only fix if there are problems. Exceptions would be drive belt and related components or other wear items (brakes, tires, etc..)
@Miguk_Saram I have ALL tools necessary to take on these jobs. I've done all work myself on the GL.
I've had the GL since 2017. I RR the rear air bags. The new Arnott front struts and bags were installed by this dealership.
The funniest part to me is the oil filter leaking. I change the gasket every time I can't understand why that would be leaking. I changed my oil every 8-10k miles with Mobile 1 40 weight. In between oil changes I added top a quarter of a quart.
The O ring in the power steering replacement I have plenty of fluid extractors available here at my house in I don't see that being a problem one bit.
I've also never ever seen low antifreeze or any leaks in my radiator but I'll double check when I get the GL back.
I've heard the serpentine belt is a PITA.
I've never in my 25 years of working on vehicles observed an oil fill cap leak. If anyone has seen this, please advise.
I have a Mityvac, however I'm unsure if its safe to suck out antifreeze with. It absolutely will not give me a full flush. There's always antifreeze is the block still.
My only question would be with the "Suspension control- Damping Control Actuator" or the "Left front air strut with wiring harness". Does anyone know exactly how to replace this I've never even heard of these parts.
The back story of how my GL ended up in the shop, is that I was hit over the summer on the side of the GL (minor) and I recently just took it in to the auto body shop and I told them they can't get an in alignment done at just any shop. I want it done at the Mercedes dealership along with my headlights being aligned correctly because they're removing the front bumper. So Mercedes dealership advise me of all these wrong things.
Funniest part about this is this is the name on this repair estimate is not my service advisor. I'll be sure to call him tomorrow and get the real lowdown on what's going on.
Again thanks for everyone's help hope to hear your comments soon.

On your Inspection Form the section regarding the oil filter gasket states "include cooler gasket, thermostat gasket and o-ring for coolant hose..". The Oil Cooler is the large metal component to the left of the power steering reservoir (so it is not the oil filter housing itself that is being referenced).

The reference to the oil filter leak is the oil filter HOUSING, not the large O-ring that seals the filter in. The oil filter housing is attached to the block by a bracket, and there are two gaskets in there that compress and leak over time. The dealer will have the block to bracket housing in stock because they are replaced so often that they probably have a regular order for it. Unfortunately, most dealers only carry the one gasket and want you to buy a new housing to get the other one. You can buy a set on eBay for less than $10 IIRC. It's an easy job but look closely before you start gathering parts. On mine, so much oil had dripped down that it caked onto the serpentine belt and the idler pulleys. I decided to replace the belt, pulleys, and the tensioner (I had the parts on hand already.) Also, if you don't want to order eBay parts, you can buy the one gasket from the dealer and just use High Temp RTV to make your own gasket inside the housing.
