Why is my 2001 ford escape xlt is shaking?

I have change the tires on it

KARL S is a KNOW NOTHING IDIOT! He has 346 POINTS for best answers. WOW! Ford is the BEST we have here and next is CHRYSLER! GM is BOTTOM of heap! TI(RES require HIGH SPEED balancing and it also depends upon TIRE CHOICES as well! I use ONLY fuel efficient tires that save on GAS, and hold BALANCING better than most others do! YOU MAY HAVE bad TIE ROD ENDS! You can check this with a FRIEND! Put key yo "ON"not START! Have friend JIGGLE the steering wheel! You put your HAND on the front tires! If you sense a POPPING or uneven motion, you have BAD TIE RODS ends or other steering system wear! TIRES should jiggle EVENLY and SMOOTHLY! Just because you have NEW tires means NOTHING if they are not REAL BRAND NAME and SERIES TIRES< like MICHELIN GREEN X, or CONTINENTAL ECO tires, or even KUMHO tires that are FUEL EFFICIENT ONES! FORGET KARL S! He knows NOTHING at all but thinks he DOES!

When does it shake? Under acceleration? Under braking? Does it start out not all that bad, get worse over 30mph, and stay really bad til you get up to interstate speeds, and start to smooth out again?

It could be a bad CV joint.

If it only shakes when braking, you have a warped brake rotor.

  • Why is my engine shaking during idle at stops and park? I got a ford 1999 taurus SE with 100,000 miles on it. I just changed the spark plugs and wireset out and it got even worse. I was thinking the IAC might of just gone bad but before I go get one I wanted to ask if there was anything else I could test before buying more new stuff for it.
  • Why does my car feel like it's shaking? I'm just wondering is it a wheel alignment that I might need? Its a Ford fusion 2011 . It feels sort of like it's shaking especially when ingot 60-70 mph on the express way. It just recently started feeling this way this past week.
  • Why is my car shaking when idle? Here's the back story. Car is a 2001 Ford Focus hatchback. Check engine light recently went on for a EGR censor. As of yesterday my cruise control will not work, and when I went to turn my car on today it is making a chugging noise and vibrating. When you gas, it stops vibrating however as you slow down it starts again. What are possible things wrong with the car? (And yes, it has plenty of gas just filled up two days ago.)
  • Why is my 2009 ford flex shaking after spark plugs were changed? After doing a tune up on my 2009 ford flex, the car started shaking and the AC does not cool. What could be the problem? I used OE motorcraft spark plugs
