You can see the OEM Air Shocks are a bit worn out!
Received the new Delco 504-547 in a pair today.

Has anyone swapped out the OEM to these Delco? The PA has the self levelling system with compressor etc.
I do not know if I can use the existing lines & adapt into the new more beefy air shocks or what really is involved yet, help appreciated.
Here is one of the kits included...

And instructions...

And the main air line kit...

Sure would nice just to use the existing air lines, however I have a feeling that may not be best.

This past weekend when I was doing the brakes on my Dad'* Lesabre I noticed the LR shock leaking oil and I was looking at this same kit on rockauto.com

When I did mine both lines were stuck solid in the old shocks. My compressor went too though from running constantly to fill shocks with holes. So I went with the bicycle valve kit.

William- I am also wondering even if I soak those two mounting bolts,what are the chances of removing them without using the cutting torch after 17 years.
About to call the dealer to have new bolts on hand as the shocks do not come with the bolts.
Justin-Ya I think there is a reason why they show scissors to cut the air line at shock.
Luckily my compressor is in working condition. It has been running more than normal lately, but it does stop, so it is not running all the time. Cold temps here are not helping much either.

Dealer wants $17 per bolt, they must be gold plated !
Apparently they are GR 8 (10.8 metric) M16 X2 75
Dec 1 is my target install date & I am going to soak the bolts for days LOL

Art,

On the 2000-2005 Bonneville the air line to the driver side is near impossible to remove without removing suspension parts. I do not know if that is the case with the 97 PAs. You may consider checking your compressor for issues prior to removing air lines. If your set up is like the lat generation Bonnevilles- you may end up keeping the original lines.

Ya Michael I hear you. I am really not sure how this is really going to go down until I start at it. One thing is for sure the old air shocks are soon going to be tossed out! Bye Bye!
I have to ensure I have good access to the compressor and toss the instructions LOL..
I have good room around the shocks, & will have to support the control arm before getting at bolts.

Which reminds me I have to also empty out the trunk and throw out the junk!
I am going to have to play squirrel and look for the shock nut, probably have to remove side access covers inside the trunk.

Hopefully PB blaster will be your friend, but if the bolts aren't reusable IDK why any bolt wouldn't do. 17 bucks a bolt seems a little stiff, you buy a whole box at that price at the hardware store.

I Will have spare bolts from the hardware store before I attempt this job William.
I may have to heat them up a bit to get them free will see. Will have air gun.
And if that does not work...I will have a to resort to a different type of .357 heat!

As long as your existing air lines are in good shape you should not need that kit, mine were a year older than yours, and the air lines were fine, and came right off easily after removing the clip on them.
I had to pull my rear seat forward to get to the nuts on mine, the only trouble I had was they did not make the hole to remove the center nut big enough for a socket, so I had to remove the two small nuts, then fight with the shock to remove the main nut, which if you don't have a vice is a PITA to do!
I wish I had just went with quick struts, but I could not fine the big convex looking washer anywhere, so I had to remove the one from the old ones, I did go with all new hardware for the rest of it though.

I went with Monroe 71798 Sensa-Trac Strut'*, of course as you know our cars use different struts, just mentioning the ones I got for my 96'
I also went with some new bolts from a Monroe AK43 Monroe Strut Accessory Kit
Only regret is not going with KYB'*, but the Monroes are not too bad, I really wanted OE AC Delco'*, but they were $$$
