Wobbling


#1

I have a 97 GMC Sierra - runs down the road smooth as can be, but when you brake - the front end (steering) wobbles, especially at higher speeds - at low speeds it sometimes does and sometimes doesn’t, but if it does it not as bad. What could cause this?Had new front brakes less than 6 K miles ago. Thanks !

This could be as simple as warped rotors, but on an 11 year old vehicle there could be other problems like worn tie rod ends. I’d suggest taking it to a good reputable independent shop for a look-see.

but if it were tie rod ends - wouldn’t it wobble all the time, not just when braking ? and like I said the brakes were just done…just doesn’t make any sense

The ball joints are a problem with these vehicles. Having one fail at speed is no laughing matter, so have the situation checked out, pronto.


#5

If the rotors ARE warped the reason may be from the tireman over-torquing the wheel stud nuts.

Check the torque value for those stud nuts and compare that to the torque on the stud nuts now.

I may be mistaken but I think the torque for your truck should be 140 ft lbs.

had the whole thing checked out all parts good, - was the rotors - turned them and good as new - thanks !
