eldo nick Posted February 10, 2004 Report Share Posted February 10, 2004 i have a 99 eldo and the front end seems to bo up & down like a boat on water what do you think it might be? no lits come no from info center. Link to comment Share on other sites More sharing options...
loucar1 Posted February 10, 2004 Report Share Posted February 10, 2004 If your front end is bouncing, I would check the front struts. I would think if you take a look under the car and at struts you are going to see oil leaking on one or both Lou 94 Seville STS Link to comment Share on other sites More sharing options...

Maximln Posted February 10, 2004 Report Share Posted February 10, 2004 I would check to make sure that both front height sensors for the CVRSS are attached properly (if equipped). The same thing happened to my car. It was real "floaty" going over bumps. I took it to the shop and both links that connected the height sensors to the vehicle had broken off. Once replaced, everything was fine. I was happy to discover that there was a wide range of damping for the struts and you could actually feel the difference.

98Concours Posted February 10, 2004 Report Share Posted February 10, 2004 Just where are the front height sensors located? What do they look like? Jeff 98 Concours 90 Seville 04 Corvette Link to comment Share on other sites More sharing options...
JasonA Posted February 10, 2004 Report Share Posted February 10, 2004 If it's a "base" Eldorado, it'll have passive struts, with no electrical connections. If it's an ETC, it probably has the active struts. Just wanted to point that out. You may have lucked out, and can get replacement struts relatively cheap (if they're not electronic).

Will these struts fit a 97 STS?? I believe mine are going south, car has 111K on it and I don't believe I will be spending the extra money on the electronic struts.

I am going to see if Koni or someone has a Hi Perf Shock avaliable for those platforms. Dennis Dennis Link to comment Share on other sites More sharing options...
Dloch Posted February 11, 2004 Report Share Posted February 11, 2004 Jason, This brings up another question, if there are passive struts for the front does the same platform use the air adjust shocks in the rear that will fit the rear as well? Dennis Dennis Link to comment Share on other sites More sharing options...
JasonA Posted February 11, 2004 Report Share Posted February 11, 2004 Yes, I believe that's the case. Even with the passive struts on the front, the Eldorado and Deville models still used air shocks in the rear. Let me verify that at home, though. My brochure and information is there.

KHE Posted February 11, 2004 Report Share Posted February 11, 2004 The rear struts may be fine. The front struts take the most abuse with all the weight of the drivetrain.

Certainly but the car has about 111K on it now, soon to have 112K after the trip this week and I would think they aren't what they use to be by now.

In fact, I've already purchased the resistors! Jason, What value and wattage resistor did you buy? I was looking in the service manual last night and actuators for the road sensing suspension (SLS, DeVille) have 2 ohm resistance while the continuously variable road sensing suspension (STS, Concours) has 12 ohm resistance. The link no longer functions. Kevin '93 Fleetwood Brougham '05 Deville '04 Deville 2013 Silverado Z71 Link to comment Share on other sites More sharing options...
JasonA Posted February 19, 2004 Report Share Posted February 19, 2004 Hmmm...I just looked at that page not days ago. Maybe he's having server problems now. I think I bought 25-ohm resistors. Let me check for you when I get home. Jason(2001 STS, White Diamond) "When you turn your car on...does it return the favor?" Link to comment Share on other sites More sharing options...

JasonA Posted February 20, 2004 Report Share Posted February 20, 2004 My bad. I just went out to the garage to check them out. They're 12-ohm, 25-watt. I think Maydog said that 25-ohm, 50-watt ones should also work, but he had success with the 12-ohm ones. Jason(2001 STS, White Diamond) "When you turn your car on...does it return the favor?"

KHE Posted February 20, 2004 Report Share Posted February 20, 2004 Is Maydog's car a SLS or STS? The resistance of the STS strut is 12 ohms and the SLS is 2 ohms per the service manual. 50 watts seems like overkill to me - Using Ohm's law, 12 volts across 12 ohms = 1amp current draw. Power = E*I = 12*1 = 12 watts. A 25 watt resistor should be more than adequate (safety factor of 2) unless I'm missing something....

A 25 watt resistor should be more than adequate (safety factor of 2) unless I'm missing something.... According to the manufacturer's recommendations, the 25 watt version would be marginal if the heat sink requirements are not observed. If mounted near the engine compartment, ambient temperature will also be a factor in the derating. ___________________________________________________ Link to comment Share on other sites More sharing options...

TDK Posted February 21, 2004 Report Share Posted February 21, 2004 Does anyone know of a "qualitative" test for struts/shocks? Does this always have to be a decision based on "feel" or how much money you have lying around? What I'm trying to ask, is there a real test with dealer or whatever equipment that has a pass-fail parameter. Perhaps mor ethat jump and front bumper and if it bounces more than twice - its done for! Got nearly 170k (high speed gravel, potholes, etc) and it seems to handle just fine as far as going where its aimed. How to tell when "the ride" is tired. Thanks Add power to leave problems behind. Most braking is just - poor planning. Link to comment Share on other sites More sharing options...
