I am getting ready to DYI the struts on my 2009 Enclave. I noticed two OEM choices.  One appears to be a gas charged strut and one isn't.

HAS ANYONE TRIED THE GAS PREMIUM STRUT? IF SO COULD YOU COMMENT?

I have a brand new pair of struts that I bought for my 2010 but never used.  I will let you have them for a very good price.  PM me.

One is OEM- as in what came on the vehicle from the factory.

the other is listed in the PROFESSIONAL category....


which is interesting-- because the BEST option-- is cheaper than the PROFESSIONAL-- which based on the description below comes in 2nd.  Go figure.



see below for the explanation

Got down to the bone.......

Talked to a GM tech specialist....this is what I got out of the conversation - if you want to go ready strut.

Three companies make ready struts, Monroe, Gabriel and KYB, with KYB slightly stiffer. As to the Gas Strut/Shock (professional ) it is heavy duty in comparison to the OE strut/shock.

Since I don't want to mess with changing out the springs on the struts, I will go with one of the ready struts and gas rear shocks (professional).

Hope this helps making your decision when it comes up.

I went with the Gabriel Ready Struts for the same reason--- did not want to mess with compressing the coil and swapping the parts.
Also installed OE rear shocks.


the info on when I researched the Gabriels....

My 2008 has 117500 miles.  The car rides horrible and the suspension seems to be making strange noises.
I just ordered the ACDelco 506-901 OE front struts on Amazon, they will be here on wednesday but I can't install them I will take them to a shop. $110 shipped.
I'm not sure if I need rear struts or not so I'm not ordering those yet.

Changed my mind, just ordered rear shocks too.  ACDelco 560-622 pair for $107 shipped on Amazon.
Also I looked under the car and noticed that one of the rear spring rubber bumper things was broken.  It is GM p/n 20838485.

I agree, I changed mine out at 74k miles and they were shot.

Just drove around to visit a few non-dealer repair shops for estimates.  I was quoted from $400 to $650 just for labor to replace the front and rear shocks.

One place told me there is a rear suspension air compressor that often fails at high mileage and they would need to test that.  I had no idea there was an air compressor in the rear suspension. So now I am researching that part and what it does...  I wonder if I can locate it and apply 12V to it and see if it pumps air into something??

Also I was told to not be too surprised if other parts like (strut mounts for example) might need replacing.

Unfortunately I don't know a lot about suspensions so I am trying to study up on it before going in to the shop.

I would call BS on the air compressor needing testing. Ask them what the price is if no air compressor to deal with or better yet walk away and find a better shop to  work with. The rears are easy to do yourself. Only two bolts. The hardest part of the job is taking the wheels off.

Other Buicks have the load leveling suspension.

Say people hop in the back--- and it drops the vehicles rear end--- the system activates an air compressor that airs up 2 adjustable shocks to bring the vehicle back up to level.

My sisters Lucerne has it-- hop in that back and it does its magic.

Even the Buick version of the Trailblazer had it-- and I think the Envoy had it too.


I have not heard anyone mention this for the Enclave

Ok sorry for the confusion, there is no air compressor suspension, or "air-lift" on the Enclave.  I got under the car and looked around and it's not there.  The mechanic that I spoke to was mistaken about that.
There is a rubber bumper thing inside the rear spring that broke.  I think it broke because the rear shocks have reached end-of-life long ago.  Cost me $60 at the dealer, or i could have got it for around $50 online and waited a week.  I think that's gonna be expensive to replace.  I tried to post a picture of it but I can't figure out how to post pics on this website.

Yep that's the rubber bumper part that is broken on my Enclave.  It is GM p/n 20838485.

I think I got ripped off at the repair shop. They quoted me $425 to replace the front struts and rear shocks and said it would be 4-5 hours. But... they finished the job in about 1 hour 15 minutes with 2 guys working on it.  So I got charged about $170 per hour per person.  Since I was dumb enough to agree to their estimate, what can I do.
They didn't do a front alignment, and said it's not necessary when changing front struts. Is that true???  Another shop had told me an alignment is needed after replacing struts.

They said everything else in the suspension looked fine. Its driving great now, night and day difference.

I didn't get the rear bumper part installed after all because they estimated $130 per side to lower the rear control arms and install the bumper thing, so I said "no thanks".  I'm assuming that now that I have functioning rear shocks, the bumper will not be doing much.

the quoted price may have been for replacing the struts and compressing coils and doing the swap.

if quick struts were used- much faster
