Very good. Mine doesn't do that...........and Gabriel must get a lot of "pop" questions if that sequence is "normal". That's quite a hard thump.
In the GM self-leveling application, the system exhausts. The drier must have some kind of role in the pressure, because the spring that comes in the kit is calibrated to allegedly corrects the PSI.
But if the system pops every time...it's got me thinking of canceling my order for Gabriels with the "repair" spring kit, and just getting the Monroes.... but I hear the monroe [front] struts are significantly firmer than OE. I wonder what kind of a balance rear monroes and front gabriels (OEM?) would create?
Currently, these Gabriels (I mean AC Delcos) are a little bouncy but the car handles really well with them, even with the soft, well worn-in stock front struts (that sometimes bottom out going over larger bumps). The Ultras in the front *should* restore the new-car feel, albeit always more bouncy due to the air-filled back shocks.
I wonder if the rears were originally manuf by Gabriel, because I read that Gabriels traditionally have had the "airbag" protected inside the metal casing, whereas Monroe has it on the outside just like the shocks I replaced did (and the rubber sleeve was cracked). Ugh... dilemmas... decisions. Any advice on that? Perhaps OE wasn't matched either... rears Monroe, fronts Gabriel ultra... that'd be odd. But it's all some kind of corporate secret (what supplier provides what etc).
we've never changed the spring when using the alternate ac delco shocks... so there's got to be something different about the gabriel shocks internally
are you sure they are the OEM for acdelco?
Yeah, hmm... well it's unlikely but maybe you and domino both got defects?
It's also possible that the 504-123 may have a smaller air bladder with the purpose of being a direct-fit replacement, but that math calculation didn't go very well. I say, from their physical appearance, they're all the same exact shock absorber. If you had both in stock maybe you could see if there are any differences (other than the threaded line vs stock original)
AFAIK their GM applications are the only ones that come with the replacement spring in the kit.
I can't remember ever getting anything but just two shocks in our kits that we sell, but we sell the 504-123 most of the time, since when you factor in the extra labor required to make the others work it's basically a wash and you might as well get the OEM fitment in that case
if i recall correctly our 504-547 kits don't come with that gabriel air line kit (we've had to order it separately) but maybe that has changed - it's probably been a year since we've done one of those kits
After taking off my ACDelcos, I was playing around with them by manually putting air through them and noticed that the air bladder on my passenger shock must not be "seated" correctly. It would hold air when fully extended, but would release air through mid travel sometimes. Since it is a covered bladder system, I cannot tell exactly "how" it seats on the shock.
I too have physically compared both the Gabriels and ACDelcos side by side at the store and they are IDENTICAL in every aspect except the air connector, which further supports Mtflight's statement that Gabriel is the manufacturer for OEM.
then why not use the same connector?
i wish we knew the full story here
It never surprises me how so many parts are interchangeable among vehicles from not only the same maker but different makers as well, but sell to us consumers unknowingly, and in many cases, the parts are listed as a higher price depending upon vehicle!
Dayum parts people!!!!!:hmm: (Just messing with you Chris :Poke:)
I would guess that the clip-on OEM style air line connector is patented or something and GM won't let them use it (or use it for cheap).
What really gets me is why ACDelco can't use it since their 'selldown'/'additional usage' part is the same as the Gabriel - but maybe that's just pricing again.
I just put Monroes on the back of my 02 Devile 2 weeks ago, I think it rides great. Nice and smooth, which considering that the originals were totally shot, is impressive.
