Question
hello my 1992 Cadillac eldarado steering wheel is shaking at high and low speeds i have had my rotors and break pads replaced with good ones not the cheap kind just wondering if you could help me out and tell me what may be wrong
Hello,
First, the rotors and pad issues are only caused by braking and not driving down the road.
You need to check the suspension to make sure everything is tight.
Secondly, the most common problem for a vibration as you describe is wheels or tires. If you lost a wheel weight, this could give you the vibration. A bad tire will do the same. This has nothing to do with tread, but if a belt broke in the tire, that would be a problem. A bent wheel rim could create your problem.
Brakes when the rotors warp only pulsate when stopping, so if you replaced the brakes for this vibration going down the road, it will not cure the problem.
A bad drive axle could also give you problems like this, but rare.
Here is what I would tell you and the cheapest way to diagnose. Check everything as I have said. If no obvious problems, get the tires balance and rotated. You will find your vibration is gone or less severe. Then you need to find out which tire or rim is the problem now in the rear.
Good Luck!

Expertise
Alarm system questions cannot be answered on this forum. These systems are not what I can answer. Without being physically at the vehicle and not knowing what kind of electrical service has been done on the vehicle, there is no possible way to give an accurate answer over the internet. My expertise is in Ignition/key based anti-theft systems. These issues include GM VATS (resistor chip in key blade) PASSLOCK (MRD)-ignition lock rotation based, no special ignition key and the PKIII Transponder (computer chip in key) systems. These systems are not alarm based and are integral with the starting of the engine. This is why I cannot diagnose alarm problems without physically looking at the vehicle: Alarm systems are a completely different annimal than ignition key/lock based anti-theft system. Many alarm questions come from vehicles 10 years old, and since older, many hands that had been involved over the years.I am an expert in all GM factory (ignition/key based)systems. Alarm system questions pose to many situations beyond my knowledge as to what has been done to the vehicle over the years. Some guy may have actually wired the stereo into the alarm system. Who knows? Over my past 30 years in vehicle wiring repair, I have seen unbelievable wiring disaters done by guys that consider themselves "mechanics." I have seen stereos and alarms intalled using surgical tape. I have seen modules burn up, un-fused circuits, wiring jambed between the doors and even lamp cord used for a starter kill. To answer alarm questions over the internet without examining the vehicle is like asking; What does it take to remove a dent?
