Sometimes, the car thinks the runway is too short and jumps so it won't crash at the end.
Also, consider checking engine mounts, transmission mounts, cradle mounts (if FWD) and CV joints and U-joints. Engine mounts and cradle mounts would be the most common causes that I've seen.
If the car is FWD, consider lightly powerbraking in Drive with the hood open and look for excessive movement suggesting a torn or weak motor mount.
If this is a Taurus or Sable, be very gentle so as not to rip the radiator or upper radiator hose. Check the mount descriped in the next paragraph for being ripped, or having a loose mounting nut. Also pay close attention to the front two cradle mounts. These very commonly rot away and cause a lurch. If it is a Taurus or Sable, replace the radiator and upper hose after repairing the lurch to prevent overheating later on. They are both already damaged.
If this is a Cadillac with a 4.5L or 4.9L engine, expect it to be the motor mount at the right front of the subframe (left front of the engine) or a CV joint of the right axle shaft.
Other less likely suspects are damaged:
strut rod or radias arm bushings, especially on Ford vehicles
ball joints
strut towers (cracked)
upper control arms (rotted or cracked) if a GM S/T truck, expect a brake pull
upper link on Mazda Millenia front suspension
strut mounts or strut bearing plates
It's almost always a wheel bearing that would cause that noise.
Timing chain or belt is broken
The starter is failing.
bad battery or loose battery cable
Sure, but you are taking a chance of getting struck by lighting if you are outside.
If you have a worn timing chain that hasnt been changed before, that can cause the timing to jump and cause your car to run very rough or not run at all
Cause it is going to frigin blow up jump out stupid.....
it's the air intake taking more air and the belts moving faster
jump on the car
The answer depends on the car.
Jump in My Car was created in 1975.
You would experience accelartion in a roller coaster, a car, and when you bungee jump.
