I am interested in the replys you get. I have a 1998 Deville with 70,000 miles and I am thinking about replacing the struts and rear shocks and springs maybe. I am looking at the struts at rockauto and they list several different types, soft ride, heavy duty and red elec adjusting struts from 150 to 575 each. How do I tell what I need without taking them off first? This is my first car with struts. Do front coil springs cost much for Devillles? My car seems to bottom out easy, maybe weak springs on the front. Is there a big difference in the brands of stock and aftermarket struts? thanks for any advice. TexasCadillac
I had my front struts replaced with SUNCORE PASSIVE STRUTS on my 1995 Deville 4 months ago and so far so good.
Since it`s less expensive to purchase the fronts and rears at the same time,i purchased the rears also in case my rear air ride ever goes out.
There really is a noticeable difference in smoothness over bumps with the new front passive struts.
I replaced my 200 DTS shocks @ 90K miles with Arnott Industry shocks a few months back. Their sensor package does keep the Service Stability nanny in check. There was an improvement in ride, but it wasn't 'like new'. The stability improved compared to the worn-out shocks, but you miss the original shock's increase in stiffness when you go into corners. Maybe it would have been better if I replaced the front springs at the same time.
I think for the money, I should have just gone with a base deville monroe or gabriel relplacement, lived with the Suspension message on the DIC, and come out ahead a few hundred bucks. Or.... should have tried replacing the front springs at the same time as the struts.
I have no complaints with Arnott Industries' product or services. I'm not dissatisfied; you get what you pay for. Considering the car's age, it isn't worth plunking a couple of grand into new OEM shocks all the way around. Passive replacements are adequate, but active shocks do have advantages you can feel.
I have a 91 deville with a 4.9l. I have done a lot of diagnostic for a apparent miss. I had a tune up which was supposed to be new plugs, wires, fuel filter, cap, and button. That was a year ago.
Still, the miss continued. I speculated on this board about it possibly being the fuel pump. I...
While driving in my 97' Sedan DeVille with the A/C on,
I get occasionally a "Low Oil / High Engine Temp" message on my display.
Checked oil, reading was perfect.
Only happens when I put on A/C after about 35 minutes.
Car currently has 104k miles.
