: Suspension, need help.

04-12-11, 03:10 AM
Hi, i just bought Cadillac Fleetwood 1994 and ride is harsh and restless, probably because it has firm springs and 4 link rear axle. I need softer ride and firm rear axle, can you help me with this?

thefleetwood guy can help you out . Your complaints tell me that you may have an aftermarket shocks .
Normally VP4 badges have little firmer ride , can you confirm that ? Just pop up the trunk and look at if you can see V4P or VP4 or pop up your hood and see if you have a mechanical fan instead of electrical .

I donīt know but in rear i have automatic level shocks. Probably springs are sagging. I will look at the fan tomorow, how can i recognise if fan is electrical or mechanical?

Run your VIN on the Compine site (see the FAQ sticky), and let us know what the "F" codes are. That will tell you the springs on the car.

I donīt really understand what you mean compine site? My VIN is 1G6DW52P5RR717691

suspension is FE2
car is also a livery car (R1P) for what thats worth

04-13-11, 03:40 AM
Yes i see, what does that mean? Can i tune suspension for better comfort and smoother ride?

04-13-11, 10:31 AM
FE2 and R1P means you have the stiffest suspension possible. For most, that is a good thing. If you want it floaty, throw on a set of Monroe Sensa Trac shocks. They'll wear out fast, though.

I would like to change coil springs rather. FE1 instead FE2, i have seen on ACDELCO page springs with numbers 45H0048 and 45H3011, are these original springs in FE1 version? And what about COMPONENT-COMPUTER SELECTED SUSPENSION? Is the same like in vesrion FE1?

04-13-11, 04:50 PM
Nobody know? It is not easy for me, because i live in Europe.

04-13-11, 06:25 PM
I don't know what parts would correspond to the FE1. Perhaps someone else can help.

I am parting out an FE1 car. If you are patient, I can hold the springs for you. That is going to be an expensive shipment, however.

Thanks jayoldschool, i gona buy new, because shipping is expensive to Europe. Computer controlled shocks are mystery to me, i donīt know shocks will do the job for FE1, i am affraid regular shocks will not mutch.

I find it hard to believe that any stock Fleetwood ride quality would be considered harsh, even with the FE2 and R1P suspension. I think the OP is right in guessing his springs are bad. The air shocks are probably holding up the back of the car which would result in a harsh, unpredictable ride.

I would guess that the shocks are probably okay and would provide a nice ride if everything else were okay.

We have terrible roads here in Czech republic, many holes. If i wanted sport suspension, i would buy some German garbage car. I love floating american cars which are famous for. Springs are too stiff.

Computer selected suspension just means exactly that.

At the factory, when the car was built, the computer selected FE2 springs for the car. They're not any different than regular springs. How many miles/kilometers are on your car?

04-14-11, 01:38 PM
The Cadillac is like new 80 000 miles has. Springs are the same on version FE2 vs. FE1?

04-14-11, 01:40 PM
No, the springs are not the same. Like I said, put on the cheapest gas shocks you can find. You will be in float heaven.

It will not has good direction, rear axle is not rigid. What is wrong with soft springs in version FE1?

Check the bushings on the upper and lower control arms.

Ok guys, i will try to change computer control shocks for convential shocks, what are the best shocks for pillow ride? And how to take out computer shocks? Thanks
