Chances are it didn't or won't cause any damage. After removing the rock, check rotor surface to see if it has any dings, scratches, etc

What cause a truck to rock side to side when driving?


Does the vehicle rock faster at higher speeds, or is it a constant no matter how fast you're going? Is it a gentle rock, or does it seem like more of a shake at higher speeds? Does your vehicle have hydraulic shocks, air shocks or regular shocks and springs?
If your vehicle is rocking at low speeds and the rock turns into a shake or vibration at higher speeds, you might have a bent axle. For this problem to be bad enough to fees as a rocking motion at low speeds you should probably be able to tell by looking at your wheels -- if your axle is bent, you should see that one of the wheels seems tilted slightly. If you move your car a few feet and look again, it should look like it is tilted in a different direction. If this is the case, have the axle replaced ASAP to avoid more damage to your suspension system.
If the rocking does not change at any speed, then you have to consider your suspension system. If you have a hydraulic or air suspension on your vehicle, it might be malfunctioning. If you have air shocks, one of the air bags that holds your vehicle in the correct position could have a slow leak -- this could cause that part of the suspension to float down as it loses pressure and back up as the pump adds more air -- which would feel like a slow rock inside the car. The same could happen with a leaking hydraulic. If this is the case, bring the vehicle in to a mechanic and have your suspension checked ASAP to avoid causing more damage to the system.
If neither of these is the case your wheels might be out of alignment. This would also cause a funny, cyclical noise from your tires as you drive and should be taken care of ASAP as it will cause extreme wear on your tires. If this is the case, your tires will probably already show uneven wear on the tread (if the inside of the tread (near the center of the car) is worn out more than the outside of the tread then this could indicate a bad alignment).
If your tires are not worn funny, and nothing else here has helped, you might have bad tie rod ends, ball joints or loose lug nuts on one of your wheels. First, make sure the lug nuts on each tire are properly tightened -- if there were loose nuts you might have fixed it. If all of the nuts are tight, jack up your front end so your tires (one at a time) is about an inch off the ground. Grab the top and bottom of the tire and try to rock the wheel -- if the top and bottom of the wheel move towards the center of the car, you probably have bad ball joints and you should have these replaced IMMEDIATELY (they are a vital part of your steering system and need to be in good shape for safe driving). If the wheel does not rock up and down, try grabbing the tire on the front and back and see if it rocks (if you have only 1 tire off the ground there should be no play ... if both front tires are in the air then pay attention to the tire on the other side of the car as you do this or have someone hold the steering wheel). If the tire moves, without turning the steering system of the car (the other tire doesn't move with it) then it's likely to be your tie rods or tie-rod ends. These are also a vital part of the steering system of your vehicle and should be replaced IMMEDIATELY to ensure safe driving.
If none of these are the problem. take the vehicle to a mechanic and tell him what you have done to check the vehicle (this can save time by helping the mechanic eliminate possible causes).

1998 mercury tracer air conditioner not working has new compressor, new alternator.


If new compressor, did the mechanic fill it with the right freon and did he check the condensor which is in front, behind your grill and in front of your Rad.
Just because you had a compressor replace... won't get you a cool car

Vibation in the front tires, tires are balanced


if you have had the tires recently check for balance ,on a SPIN balancer,that would eliminate a belt wheel,because you would see that on a spin balancer, and tire balance.But don't forget to check tire pressure too.
find a place where traffic won't run over you and from a dead start get your speed up to 5mph,then 10mph,then 15 mph,then 20mph,
what you are looking for here is the steering wheel to start rocking back and fourth that would tell you a tire steel belt has shifted or separated.
but if your **** is what rocks back and fourth then its a back wheel or tire causing it.if no rocking appears then you need to check for loose steering parts,the passenger side ball joint first.

Slight lopihg when taking off think it needs axle shaft adj


If you mean that the vehicle shakes under acceleration as if the whole drivetrain is rocking back and forth then you may be on spot with the axle shaft causing the issue. When an inner cv axle joint becomes damaged it can cause this. I am afraid there is no adjustment for the shaft/joint. It must be replaced. Be sure to inspect engine and transmission mounts as they are a common cause of the axle shaft failure. When the mounts wear or the rubber breaks/disintegrates it allows one side of the engine to sag causing the inner joint to bind and break internally. I have found that most often it is the transmission mount that causes the problem, but have seen engine mounts do it too.

Wheels Makes Noise...


You need to have your brake pads replaced. They make that sound when they get worn down so you know to change them. There is a little piece of metal that rubs on the brake rotor to tell you this. Hope this helps

Sunroof doesn"t open or close


Section 01-17: Roof Panel, Sliding—Electric 1996 Taurus, Sable Workshop Manual DESCRIPTION AND OPERATION Electric Operation The sliding roof panel (502B98):
  • is available as an option.
  • is electrically operated through the accessory delay relay (controlled by generic electronic module (GEM)).
  • is of self-storing design.
  • requires a specific headliner.
  • utilizes a unique roof console and dome lamp.
  • has an air deflector.
The electrical system operates in the following manner:
  • Two switches control movement of the roof panel.
  • When the SLIDE roof sliding panel switch (15B691) is rocked rearward, the roof sliding outer glass panel (502A82) slides into the storage space between the roof trim panel (51968) and the roof panel, exposing an opening over the front seats.
  • When the SLIDE roof sliding panel switch is rocked forward with the roof sliding outer glass panel fully back in the storage space, the roof sliding outer glass panel moves forward from the storage position.
  • The rear portion of the roof sliding outer glass panel moves upward on two lifter arms near the end of the forward travel, allowing a weather-tight seal when the roof sliding outer glass panel is closed.
  • An AUTO feature allows the SLIDE roof sliding panel switch to be touched momentarily to cause the roof panel to automatically move to the fully open position.
  • When the TILT roof sliding panel switch is rocked forward with the roof sliding outer glass panel fully forward, the rear of the roof sliding outer glass panel pops up to the VENT position.
  • With the roof sliding outer glass panel in the VENT position, rocking the TILT roof sliding panel switch rearward closes the roof sliding outer glass panel.

How do I fit a new transmition


Automatic vehicles does not have a flywheel, it is called a flex plate that is bolted onto the cranck shaft and onto the torque convertor.
The easiest way is to put the transmission on its tail standing it upright taking care not to damage the sael at the back and than slowly lowering the torque convertor down on the shaft turning it at the same time to make sure that it engages in all the different splines in the transmission.
If the flex plate is broken it means that something caused it to break, make sure the transmission is in good condition and not jerky when you drive.
Also make sure that the bolts that holds everything together is propperly torqued, loose bolts can also cause the flexi plate to crack and than eventually breaks
