Weird Undercarriage noise

So recently my truck has been making a noise i've never heard of. I've tried to pinpoint the noise with no luck, but it sounds concerning. Any way, here's a description, hopefully someone knows what causing it or at least can point me in the right direction:

NEARLY every time I shift my truck into drive and roll a few feet, underneath my truck (sounds like from the front side of the undercarriage) there is a clanking noise that happens just once. and then I don't hear it anymore. Also, it occasionally happens when I'm begin backing up as well. My dad seems to think its the brakes but I'm not convinced. I'm leaning towards driveshaft.

Any help is appreciated!

 

Lube the u-joints and shaft.

 

Yep

 

Yep

 

IIRC 06 sport's don't have greaseable joints.

To check if it's a u-joint, start truck and put foot firmly on brake, shift between D and R repeatedly, if it's a joint you'll usually be able to hear it.
If that doesn't do it, next trick.
To see if it's brakes.
Start truck, foot firmly on brakes, put in D roll forward 10ft apply brakes firmly, put in R roll back 10ft; repeat.
If this causes noise you have pad slap. ( pads moving inside caliper )

 

My uncle had a 1st gen that had similar symptoms. He's had the truck for over 10 years and never greased the u-joints and drive shafts. After we greased it up, noise went away. Maybe the u-joints need to be replace if it is not grease serviceable.

 

My '12 has some pad slap. It sounds like right side has one clank when stopping forward after a stop reverse and vise versa. I had planned to check it out next time the wheels were off.

 

just went through the whole u joint issue last year with this truck. replaced every u joint on the shaft one at a time. Because of this, I can only wonder if it is the u joints, why they wore out so quickly.

 

LOL, that is just your brake pads. They float, so anytime you change directions forward to reverse and use the brakes, you may hear them knock a little bit. Nothing to worry about.

 

It hasn't been doing this all along though. Also, its not just when i change directions. I can go get in my truck and throw it in drive all begin pulling off and after rolling 5 feet (even before pressing the gas) I will hear the clanking noise.

 

The caliper has a spring on the bottom pin go buy 2 more put on top pin also clank will go away pins that holds brake pad

 

Tighten the 4 bolts in the crossmember under the transmission. I had the same problem. That fixed it.

 

Hi all.

Sounds like the same as mine. I have a '12 and I hear that sound every time I take off after starting the engine - forward or reverse. It sounds like a light clunk. I was concerned and this is the direction a service guy pointed me to. I then found this in the repair manual.

From the 2012 RM - Brake control - Vehicle stability control system - System description - Section 3a


When the vehicle speed first reaches approximately 6 km/h (4 mph) or more after the ignition

switch has been turned ON, each solenoid valve and the brake actuator motor are sequentially

activated to perform electrical checks. During the initial check, the operating sound of the motor

can be heard from the engine compartment, but this does not indicate a malfunction.


I am convinced this is what makes the sound in my taco. It may or may not be your issue ...

Cheers
Ray.

 

Can you post up some audio of said "clank" So far it seems the "clank" means something different, now if you said it sounds like a piece of wire wrapped around driveshaft I'd say easy, Ujoints...

 

Who replaced the u-joints? Did they install them properly? Did they grease them when they installed? have they been greased since?

A u-joint without proper installation or grease will fail quickly, leaving you wondering why this happened.

I've seen u-joints fail in 6 months from this.

 

In addition to what others have mentioned, check the two 17mm bolts that hold each brake caliper to the spindle. Take the tire off, look on the back side of the caliper, they'll be clear as day which two I'm referring to. While you're there check to make sure that each caliper has two pins going through it, holding the brake pads in place.

 

I've had a similar problem with my 07-Taco!! At low speeds, I heard a squelling sound. As I started to speed up, the squelling sound went away. This also happens when I went reverse. Thought it was my rear drums...changed them out (never again...if you do, get the proper tools) Ok, sorry about that. The noise was from my U-joints wanting to fail around 85,000 miles. Changed them out (3) and all was good with the world again.

 

I know this thread is a little old now, but did you ever get this resolved. My 2011 makes a noise when just starting out in drive as well, but only if I reverse first. It makes it after I go about 10 ft and sometimes does it in reverse too.
