You have one or two warped front brake rotors.
Many things can cause warped rotors. Here are a few.
1) Braking quite a bit, causing the rotors to heat up, and then going through a mud puddle or water which will cause rapid cooling of the disc.
2) Rotors made in China, which sometimes will warp prematurely.
3) Rotors that have been "surfaced" (ground down) during a brake job beyond their recommended thickness.
4) Bad luck. ( re: Heaven knows)

3 Cures. (You ain't gonna believe this!)
a) Take the offending rotors off and hit them with a sledge hammer. This worked for me once. ( You frighten them to death.)
b) Take the car or rotors to a shop and see if they can "turn" them on a machine to true them up. This is the same machine that is used to "grind them down".
c) Replace them. I recommend no Chinese. (See above)

1970 f250 with 360 violently shake occasionally when slowing down any ideas on what it is.? also my front driver side tire is splitting


I think you answered your own question. The car will shake, rattle and roll with a unbalance tire. You should replace the tire before you cause serious damage to your frontend.

MY JEEP SHAKES WHEN I'M STOPPING OR SLOWING DOWN. IT ALSO TENDS TO SHAKE WHEN I'M ON THE FREEWAY GOING OVER 50. WHAT DO YOU THINK IS CAUSING THIS? THANKS,


Four things to check; tires, shocks/struts, differential, and breaks.

tires: check to see all the tires are balanced and at the proper pressure

differential: if you are hearing a grinding sound and there is oil dripping from the rear or front differentials you should et them reaired

shocks/struts: push down on the bumpers if you are able to bottom out the susspension then you need to replace the shocks/struts

breaks: if your breaks are squeaking or you hear metal grinding then you may need to replace the brakes

the differential would be your most likely candidate for the problem the way you have described this problem, but don't rule out the others because it may be a combination of the problems.

A few possibilities.... bent rim, broken steel belt in tire, or a wheel weight that keeps the tire/wheel combination in balance has fallen off. Not sure how big the bump was, so other options would be suspension related. I would check the tire and/or wheel first.

Front end problems


hard to say what is the symptoms front end shaking or shimmying could be a tire out of balance, bad tire(broken belt, goose egg on the tire). is the tires screaming could be alignment problems. is it pulling to one side or the other could be a hanging break caliper (pulls to side caliper is hanging on) alignment problem (bent or broken tie rod ends) car shakes or shimmy when brakes are applied usually is a bad or warped rotor. the possibility is endless.

Wheel shaking?


There are many things that can cause front end vibrations, I will give you a list and hopefully the information provided will allow you to narrow it down. Usaully front end shake is caused by a tire that either has a shifted belt in the tire or the tire weights could have falled off and the tire and wheel must be rebalanced, another reason for shake is if the shake occurs when applying the brakes it is a warped rotor and the brakes must be replace in the front end along with new rotor installed, the last thing that it could be is a loose or worn out front end part perhaps a tierod end. If i was you I would try rotating the tires from the front to the back and see if the shaking goes away if it does it is most likely a bad tire (shifted belt) or the tire needs to be rebalanced at a auto garage. after checking that first then jack up the front and grab the wheel and move it back and forth up the down to check for play or loosness, as I said if the shaking occurs while applying the brakes replace the brakes and rotors.

Front end shimmy


Sounds like you may have some large tires on the Jeep. Check the stabilizer rod that attaches to the frame and down to the front differential. It may be loose or have worn bushings. This would cause the front end to shake at times. You probably get this problem to go away by applying the brakes a little or slowing down quickly to a certain speed. If that is the case check the rod and bushings. Good luck.
