My truck is wobbling when I hit the brakes. It mainly vibrates when I start to slow down after high speeds?

Question

The 2003 Explorer sport has 60,000 miles on it and has never had any major tune ups done to it. I replaced the brakes, tires, and I'm about to do the spark plugs and wire kit. Does anyone know what this is?

Answer 1

I would say your tires are out of balance or your rotors need to be checked.

Answer 2

If not a warped brake rotor. I would check for worn suspension components (tie rod end) and then check the alignment. The shimmy that you are experiencing would most likely be caused by uneven tire wear. The Explorer has limited adjustment for caster, and no adjustment for camber without the installation of service bushings in the upper control arms. This situation can cause diagonal banding (uneven wear across the surface of the tire) A competent alignment technician can diagnose the problem with an inspection of the tires and suspension.

Answer 3

Brake rotors are warped because you step on the brakes at high speed too hard, too often, and the new ones weren't properly broken in. Explorers are inherently bad for this, since they are lightweight chassis with too much weight to stop with itty bitty brakes. Been there, done that, got rid of the piece of junk. At 70,000 miles, everything starts to go to crap: thermostat, transmission, brakes, wheel bearings, ..........Good luck with the spark plugs. Get ready to pay someone to pull the heads off. It hasn't started on fire yet? You're damn lucky.

Answer 4

you can check the rotors yourself with a steel straight edge. another source could be the proportioning valve. abs systems are sensitive. a little bit of trash in the fluid will cause problems. you have to be careful when you push the caliper pistons back to change the brake pads, you could damage some of the seals. also if you did not clean the rotors well when you changed the brakes there could be some kind of residue on them that would cause inconsistent operation.

Answer 5

not knowing who replaced the brakes, but, you need to have someone 'turn' the rotors which takes the warp out of the rotor, usually caused by water getting on the rotors while there hot, also not torqing the wheel nuts back on can be a factor in warping the rotor

Answer 6

You have a brake rotor on the front out of balance. replace them and it should go away. I have an explorer with the same problem.

Answer 7

i think of the 1st answer in all probability advance into good - warped rotor. it rather is achievable to have the rotor grew to become at a brake save or device save to remedy the concern, yet rather rotors are low-priced so replace them is in all probability the two greater effective and less difficult besides.

Answer 8

this vehicle has warped brake rotors. what is happening is that the rotors are warped , and will need to be machined. i recommend having them checked/ machined. these rotors have a min thickness spec have them checked first to see if these rotors can be machined. if they are below specs they will need to be replace. the reason you fell it at faster speeds are becuase the rotors are turning fast as you slow down the less you feel it.

Answer 9

Your disk rotors are warped. You need to take into to a brake service place and they can turn your rotors smooth on a special machine. This is a common problem.

Answer 10

If you have already replaced the tires, that eliminates a busted radial belt. Your best next step is to replace the rotors; One or both is probably warped.

Answer 11

Time for a check up, this is either brake rotors, or bad wheel bearing neither are fun to change,a nd neither are easy if your a novice. Consider my last statement, make good decisions.
