Vibration when coasting
 
Does anyone have any idea why when coasting in my 01 tacoma 4x4 I get a weird vibration that I don't feel when the truck is under a load.
I am really at a loss on this.

Rear end, how many miles on the taco?

Pinion bearing?

The whole truck vibrate or is it coming from the front or rear?
Check for a bad u joint.

Replaced the rear end two years ago. Less than ten thousand since replacement.
The truck has around 160,000 miles.

I thought u joint also, but there isn't any noise or vibration when I accelerate or decelerate.
I can' t tell if it's front or rear. It seems to be the entire truck. It's not a huge vibration but it is noticeable.

Does it have a 2 piece driveshaft? If so, the carrier bearing may be hosed.

Sounds like a u-joint to me.

Two piece drive shaft. I will check the carrier bearing. Thanks all

Tire(s)?

Muffler bearing.

Coasting uphill or downhill?

2nd the ujoint diagnosis.

Under load the ujoint will have no free play. No noise.

My F250 4x4 does this if I leave the Warn manual hubs locked in on dry pavement. A slight, but noticable vibration.

Wait!

Maybe your wife had the vibrator seats installed and forgot to tell you!

It only vibrates when she is coasting. Errr I mean when I am coasting.

When you're coasting is exactly when the vibrator is needed!

A Rear tire out of balance can also vibrate the car while coasting

Tires to be rebalanced to hopefully eliminate the bad vibe
