Clicking Sound from Under Truck

When launch from a stop at at least half throttle a clicking sound can be heard. If accelerate slow the sound does not occur.

Sounds like its coming from under the back seats.

Suspect could be u joints on driveshaft but wondering if a bad pinion axle or something else in differential could also be making this noise.

 

I would definitely look under the truck and see how crusty the U joints and center bearing is

 

Does pinion gear or axles make this clicking sound too?

Or is it mainly more a bad joint noise?

 

Sounds to me like a u joint issue. Start there,do you have a slight vibration when you first start out?

 

No vibration when I start out. Sounds kinda like a baseball card clicking against a bicycle tire.
But I've had a shuddering for years that happens when trying to maintain speed 20-50 mph at very light throttle. Replaced torque convertor few months ago so know shudder is not torque convertor lock up.

 

Last replaced U JOINTS in 2016 they are Moog. I will probably try to get Spicer if I replace them all again.

 

Bad pinion or axle bearings wouldn't make a clicking noise, they would make more of a whining or grinding noise.
I agree with the others, U-Joints would be first suspect for a clicking noise.

 

Click or clunk when you back up? Bad U's often shift around with a change in rotational direction.

 

You mean try backing up instead of driving forward to find a difference?

It only happens when i take off fast from a stand still.

Are you thinking I should go fast in reverse? Challenge accepted LOL

 

I think he means just going from drive to reverse and vise versa if you hear a click or clunk.

 

Someone zip tye your D/S?

 

Not sure if your 2WD has a Carrier Bearing like a 4WD does, but you could check that hardware to ensure it’s tight

I agree with you and others that u joint is lead case. You could shoot them all with grease and see if it changes sound intensity at all. Might help narrow it down to that

 

This is a Prerunner V6 and yes it has a carrier bearing because I changed it 4 months ago with a spicer factory replacement.

 

The Moog u joints I have on there now are not grease-able but that sounds like a good idea.

 

Put it in reverse and do not hear any noise backing up. The noise is only when take off fast from being stopped completely.

 

I know its been a while but I'm having the same issue. What was the cause of this?

 

I think i had a u joint that had seized and binding because it was out of grease. It would not move around at all.
