Front end shakes when brakes are applied..

I have a 1988 GMC Suburban,when the brakes are applied the front end shakes bad. It feels like the tire is going to come off. I had the brakes replaced 1 week ago .The truck swerves a very little when it is in drive. It shakes even when I apply the brakes at low milage.If I apply the brakes fast and hard I don't feel the shaking.
Thank you very much..From a family man with 5 kids.......

Your rotors are warped. When you had your brakes replaced - did they just replace the pads? Did they "turn" the rotors - or replace them? It isn't very expensive to have them turned - which means they will resurface them - removing any high spots. One thing to note - by law, the rotors have to be a specific minimum thickness - if by turning them, they would become too thin - they won't (shouldn't) do it. They will put calipers on them to determine the current, and end result of the thickness and let you know before then actually do the work.

Also - it wouldn't hurt to double check that all of the lug nuts are tightened to 100 ft/lbs on all 4 wheels.

Hope this helps and good luck!

sounds like your front end is out of alignment check your tires for wear other than in the middle and take to tire shop to see if the tires are balanced right

When i drive it it shakes really bad it has new tires and have hade them balensed severl times


The front end of the vehicle has several parts that cause the front end to shake. Have you had the front end checked for bad tie rod ends, That is the most common problem.Another thing when does it shake? If it shakes while applying the brakes it could be the rotors need to be turned or it could be both the tie rod ends or the rotors.

When driving the drivers side front tire seems like it shakes, I dont know if tires are bad or something with the front end.


check your tires for cupping by looking for chopped or small flat spots ,steel belt wire sticking out, and rubbing your open hand along the tread.these vehicle are bad about wearing out the tie rod and pitman arms.also if your shocks are over 2 years they may be weak and need replaced.wish you the best.

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 problems


You seem to have more than one problem, first of all the balding tire you have a negative camber problem that can be adjusted by getting a wheel alignment done. The shaking problem while applying brake could mean that you have bad/warped front rotors. It can also mean bad Tie rods. Lastly it can mean that the front tires needs to be high speed balanced. Good Luck
