Vibration/shaking in the front end with hard accelerating through turns.

[timehoc]

Hi,

New-ish 4th gen owner. When I accelerate hard through a turn my front end start to vibrate/shake somewhat violently? Is this normal (traction control or tires giving out)?

For context it's somewhat hard accelerating. I'm turning right out into far left lane (two total) and gassing it up a freeway on-ramp. Total length from turn to on-ramp is about 600 feet.

No vibration/shaking during straight line acceleration.

Thanks!

I don't know exactly what it is, but it isn't normal.

I'd start with an alignment check first. Many places will check it for free.

After that, I would lift the front end and make sure that the tie rods, rack bushings, CV shafts, and all other front end components are tight and in good shape.

After that, I'd really check the driveshaft u-joints.

Wheel bearing?

Thanks all. I brought it into my local mechanic for a visual inspection and test drive. They were able to reproduce a fraction of what I believe I was feeling and said its operating as normal due to traction control. Visually everything looked normal.

I've only really felt heavy shaking is in the morning (when the roads are more moist) or when its actually wet from rains so maybe it is operating as normal. Will keep monitoring. Thanks for all your insight.

Is this truck lifted? If it's lifted and also has aftermarket axles, ie - duralast, then its the axles binding up.

Not significantly. FJ coils and 5100s at the lowest setting. Right CV is Napa. This is happening in 2WD FWIW.

You should really slow down in those turns:

The normal operation of "the nannies" (stability control and whatnot) involves the gas pedal shaking and vibrating to grab your attention. This isn't that?

You might want to do a "zero point calibration" of the VSC accelerometers. Search on this forum and you'll find out how. If that calibration is off a hard fast corner can make the VSC think you're losing control and it'll start pulsing brakes and whatnot.

I assumed it was "normal" but when it does happen it's pretty violent so was concerned.

Interesting. Will give this a shot.

My aftermarket axle was binding horribly. Replaced with a used oem from ebay $70 plus 20 minutes to replace.

You guys keep mentioning binding CV axle issues. Won't the axles loosen up overtime?

My runner is in the shop right now with the same issue of heavy vibrations on turns only. Did you figure out what the problem was?
