My front end shakes when i deselerate i cant go over 40 mph

you may have a faulty wheel bearing or bushing in front suspension

Hi, you could check your engine mounts.

balance the wheels????

Alignment,or front tires need balanced

Check the condition of your tires and suspension. this problem is usually caused by bad component or alignment. Special attention is given to camber and caster.

tie rod end

check your tires for balance, the check the bearings inner and outer, and the front end links to make sure you have no ware and tare... and finally, the front end alingment.

Get your tires checked out, you may have a seperated tire, or may need to get the balanced checked. and check your air pressure. then while your at the shop get your suspension checked out. while its up in the air.

try the simple solution first put your front tires on back and back tires on front. check your air pressure then take it for a drive and see if any thing has changed. if so you probably have a badly worn tire. if no change have someone move the steering wheel back and forth wyle you are under the fornt of the car (dont forget to chalk the wheels) and see if any of your steering components are loose/moving. if nothing is loose and your tires are good try to bounce the front end. if you can really get the front of the car going up and down pretty easy you havce bad struts/shocks.

How about the CV joint?? were they inspected for wear??
