: Shocks on performace Edition?

04-30-13, 03:29 PM
I own a 2006 DTS Performance Edition. I came out today to the parking lot and realized my car was sitting crooked. The left rear side of the car is low, it seems the shock blew itself out or something? I can hear the air trying to work and have no lights on the dash(yet) about ride problems. I am guessing it's just the shock? Two parts places told me that I could only buy a conversion kit or I had to get Cadillac parts from the dealer. Is this true? And are these going to be some higher or different shocks since it is the performance edition?

THANKS! That's it, and it's the shock for sure. We were going to do the conversion kit but I hate that warning about my suspension...going to spend the extra money.

I think that is a wise move... :)

The ELC system inflates both rear air bladders at once. A leak anywhere in the system will cause the whole rear to sag under load, not just one side. You have more problems than just a leaking bladder.

You have more problems than just a leaking bladder.That depends....

No. If one side is lower than the other, it has nothing to do with any part of the ELC system.

Would it help if I capitalized the 'd'?

Yes. LOL.

Wait... So I recently changed my rear shocks with some KYB brand shocks, I didn't know that I had to buy a conversion kit or anything of that sort. I just assumed they were a plug and play type part. I did notice a couple weeks ago my service suspension sys DIC message came one, and my right rear shock was low. But now everything looks fine, no sagging and no message. Can someone please elaborate.

Is yours a performance model? Do the replacement shocks have air bladders on them?

Again.....Shocks have nothing to do with the rear being low on one side.

Well I find my platinum 1se to be riding just a bit higher than in the rear than I would expect. Can any share some photo or measurement of how high/lower the rear sits

No my car is just the base model, the old shocks did have air bladders, the new ones don't. I assumed that it was low on one side because the shock was not holding air. Is this issue posted by the thread creator, only related to the performance model?

Front right and left and left rear measure at 28" 1/4 (from ground to top of wheel housing). My right rear is measuring at 27" 3/4. Back when I was getting the service suspension sys it was measuring around 26".

If your new shocks don't have air bladders, then they're not leaking air.

Do they have helper springs on/in them?

Your rear coil springs are relatively soft, and are not designed to work without the ELC system. There are "conversion kits" with helper springs, but they provide a harsher ride, and will still sag under heavier loads.

If you have a side to side ride height difference, you have a broken/sagging spring, or damaged suspension components.

The performance model has Magnetic Ride Control. No after market replacement dampers are available.
