#51 of 3244 It's the traction control. by weltron Mar 22, 2000 (4:01 am)
Golfnut it is the traction control doing a self test. On my 95 GM it performs this test at approx. 13 miles an hour after you first start the car and not again until you turn it off and restart it. I also heard this noise and thought what the hell is that. It wasn't until I received the shop manual that I could find out what it was. It is the pump running that you hear.

The noise must be from the trac control as Weltron mentioned. I don't hear that noise as I don't have trac control...but I do have the hdlg/perf pkg w/self adjusting air shocks. Haven't heard any noise from my air shock system self adjustment. Let me know your observance of your instrument cluster during the DARK hours...and if the trip odometer appears disproportionately bright compared with the rest of the cluster. Thanks
#54 of 3244 14 mph pump noise by btroy Mar 22, 2000 (3:17 pm)
Not to be a stickler on minor details, but I think the pump self-test noise is part of the ABS system. The TC system works through the ABS system, of course, but if you don't have TC, you should still hear the pump test.
#55 of 3244 3.55 axle ratio by rjones62 Mar 22, 2000 (4:39 pm)
I am thinking of ordering a new Crown Victoria with the Handling and Performance Package but I do not want the 3.55 ratio. I would rather have the standard 2.73. My questions are, can I special order and have the 2.73 instead of the 3.55 and if not how hard and costly would it be to change over once I receive the car. Thanks for your help.
#56 of 3244 I stand corrected. by weltron Mar 22, 2000 (5:13 pm)
Btroy is correct, it is a self test for the anti-lock brakes. This is an excerpt out of Fords service manual: Each time the vehicle is driven, as soon as vehicle speed reaches approximately 20km/h (13mph), the anti-lock brake module turns on the pump motor (2C256) for approximately one-half second. This is a normal function of the self-check by the anti-lock brake control module.

I have a feeling a big factory like that may lack the flexibility to take on special orders like. Just a guess. Do you want the 2.73 ratio because of fuel ecomony?
#58 of 3244 RE: 14 mph pump noise by cebuano Mar 23, 2000 (5:35 am)
I guess I'll have to try listening for that pump test next time I reach 13-14 mph. Frankly, my new CV LX with h/p pkg has such a smooth and quiet ride that I just didn't notice many noises other than the touring tires making their way over the pavement.
#59 of 3244 Shocks Need to go? by dukec Mar 23, 2000 (5:59 am)
My 1996 MGM has 66,000 on it with oem shocks. Do they need replacement, cause for me it really is hard to tell. It is the GS model and it really feels like it floats down the highway and keeping in a straight line is like hell. I love the car, but driving long distances can be cumbersome. Also, when I turn the wheel to either extreme, I hear a weird grinding noise. Must be related tot he suspenion, but was wondering if anyone had the same experience.
#60 of 3244 shocks by btroy Mar 23, 2000 (1:47 pm)
diagnosing shocks on your own car can be really tough because they wear out so gradually that you can't really notice it, and you get used to it. I wouldn't be surprised if they were totally worn out at 66K. One thing you can do is the bounce-test. Using all of your body weight, depress one corner of your car and let it rebound. I believe it should spring up and then settle down slightly to the normal level. If it bounces up and down more than that, they should be replaced. You could also get a Ford mechanic to test it, or you could test-drive a new one and see if the floatiness that you feel in yours is absent in the new one.
