How do i change tie end rods on 2002 pontiac montana?

youl be looking for lower control arm bushings and worn tie rod ends

Tire balance first and have them shake down ft end

If it's the front end that is shaking, check the ball joints, motor mounts and idler arm. Lift the front end of the van until tires are off the ground. Wiggle the front tires side to side checking for slack, use a pry bar or 2x4 to lift the wheels to check for slack. Everything should be tight. Have someone turn the steering wheel back and forth while the van is on the ground and look for loose connections in the front end. If any loose connections are found replace them. A mechanic can do a front end inspection for you for little cost if any at all. CV Joints generally do not cause any vibration when they are worn out; however, they will cause a lot of clicking noise when you turn corners once they have worn out.

yes the inner is farther on the steering rack the out is at end connnected to the knuckle by the wheel

you are apply torque to the engine upon pushing on the gas pedal so the law of nature states the engine mount maybe broken

sounds like you need tie rod ends and brakes and rotors

not a big problem. It may be tie rod wearing. If you hear a click when turning it would be the ball joints. If it does not make clicking sound, then most likely tie rod ends or improper alignment

It sounds like you need a tune change at least the wires and plugs it also could be a worn or broke motor or tranny mount.

Check the passenger side tire.

rack and pinion is the steering wheel joint, so if the steering wheel shakes or handling has decreased, then i would say it is the rp. , also check the wear on the tires for uneven wear, it could be alignment, does the steering pull to one side? it could be motor mounts just find the bolts and check em wiht a torque wrench, also inspect mounting bushings as well. to check trans. give it alot of gas to get past 35-45 mph and the shaking should go away at higher speeds, if it doesnt then its the trans missing "third".
