I have a 2005 z71 crew cab. Driving last week I noticed a vibration on the front passenger side when making slight left turns or corners. Monday I was driving home from work when around a curve and it felt like the tire was coming off or almost if it was flat then it started vibrating really bad it starts a 20mph and doesn't stop and since then my brakes work for a moment then goes straight to abs.. It is currently Un drivable. Bought it used 3 weeks ago. . HELP!!!! PLEASE

 

My first thought as to the vibration in the right front during left turns would be an abnormality in the tire that becomes more prominent when loaded. Check the front right wheel bearing, it could be beyond bad, and exhibiting some severe signs of wear.


The brake to ABS?? If it happens at low speeds <10mph, may be due to a wheel speed sensor malfunction. GM has a TSB on this for certain vehicles due to improper clearance between sensor and ring. Or it could be a byproduct of whatever is causing the vibration????????


Just thinking out loud. Good luck.

 

Get it to a shop and up on a lift. Easy then to check out the front end of the truck. Could be a right wheel bearing, a caliper problem including loss or breaking of one of the mounting bolts, or badly warped rotor. Drive at 25 MPH or have it towed.
