Pedal vibration

Wvfirefighter · July 31, 2017

Hey guys I'm sure there's more written on this topic but I didn't have a chance to search it. Whenever I'm making a low speed turn (16 - 25 mph left or right) the gas pedal vibrates and so does the brake.. the truck is a 2014 ltz 1500 crew with a 2"level kit. Antilock brake or traction control? It even does it with the traction control button off..

Traction Control is only used to start moving from a stop so isn't used while in motion. If it was the antilock brakes working then only the brake pedal would vibrate.

So it makes me wonder if the leveling kit may not have been installed right. Did it do it before the leveling kit was put on or did it start after? If it did it before the kit was put on then go to the dealer and have them look at it under warranty. If they don't want to warranty the fix and says you'll have to pay out of pocket then take it to a local garage. I wouldn't pay the service department at a dealer one cent to be honest.

It done it before the level also.. I've been putting it off going to the dealer because our local Chevy dealer is a joke. They probably wouldn't be able to duplicate the vibration just driving around their lot or taking it out on the highway.. (they definitely wouldn't bring it down to where I live where the truck actually acts up) . I'm kinda hoping something would just give out and break already so I'll know what it is. Lol

It actually reminds me of the vibration you get when the truck tries to spin on wet pavement or something... of everything is off in the can my wife can actually hear the pedal.

Anyone?

If you are turning very sharp while traveling slowly you could possibly be "scrubbing " the front tires, for lack of a better word and this will cause the nannies to kick in.

Try to get it to happen in a place you can repeat a few times, like on mine it always happens at the bank and at a Wendy's parking lot.

Just try to watch for any TC light on the dash when it happens.

I don't think any scrubbing. Factory size tires and wheels. I feel like it has got to be a sensor of some sort. No lights on dash or anything either. Really annoying. Makes me not want to drive it coming out of my holler where I live

Alright guys been trying different things to narrow this down.. if I hold the traction control button down for several seconds the tc light comes on and stays on. Then the stabilitrac turns off.. if you release the button after the display message disappears the stabilitrac will stay off but only for a short amount of time.. if it is rwleased before the message goes away it stays off only for a few seconds. Having said that, when the stabilitrac is off the truck has no pedal vibration or quiver.. so is something wrong with the stabilitrac? Should it turn itself back on automatically like this or stay off like I would like..

My truck does the same thing. I have noticed it on the same turn at the same spot a couple of times. It almost feels like the gas pedal kicks back at me.

Of course we've checked to make sure the truck is not in 4wd mode....

One wheel is turning slower than it should causing the ABS to be applied. How many miles of the truck? Could be a bad wheel bearing or loose wire on a caliper.

Skimmed page. Not vehicle specific. Just throwing out generic turning wobble stuff:

Might be the clutches in the rear diff chattering due to low or improper fluid.

Might be loose front hub bearings.

Possible rotor issue (warped).

Might be a bulge on the edge of the tire tread

Alignment

Loose front end parts - tie rods, ball joints etc.

Definitely not in 4wd.. I think a sensor or something in the wheel bearing or wiring is bad. Truck has 41k miles on it.. dealer said it would cost me their hourly price (80 dollars) til they determine the problem then the fix (if any) would be covered by warranty. Total bs...like I said I can turn the stabilitrac off and the problem goes away.
