Help Needed Identifying a Noise

[toyotaaddict83]

Hey mudders,

After putting on my new suspension, My brother and I have began diagnosing this strange noise. Its the weird metallic ping/clicking sound. Please disregard the alternator whine. This noise began before the suspension update, so I doubt it is connected to that. It happens when the powertrain is under load, so accelerating or climbing a hill slowly. It does not matter if the wheels are straight or turned, its mainly associated with stress on the powertrain.

Here is the link to the video:



Any help would be greatly appreciated, thank you!

If only occurring under load I would suggest checking your motor and exhaust mounts to start.

Exhaust shields often make weird noises.

It sounds exactly like my bad u-joint did on my front driveshaft for about 6K miles before they started vibrating so bad I had to figure out what was going on.

I would also put my money on bad U joints.

Does the noise occur more often when the front wheels are turned and under load, or equally if driving straight versus turning, under load, coasting?

Hmmm.. I had a very similar noise...there is a metal bracket that goes on the exhaust down pipe and I believe it holds it to the block or transmission, not sure because mine was missing the attachment bolt. It was just hanging on the exhaust and clanking up against stuff when accelerating, decelerating and bumpy roads. It might be a U-joint, but usually U-joints make a constant noise which increases with speed unlike what you have. I would almost bet it's part of the exhaust. Check the two rubber isolated mounting brackets the rubber separates and looks good at a glance, but they allow the exhaust to move around and bang up against stuff.

I will check everything that you guys have suggested. Thank you so much for your help!

Edit: Now that you mention it, I do remember hearing something squeaking a while back that mysteriously when away.

The sound is not influenced by the direction of the wheels. We hear it whether the wheels are straight or turned.

Ujoint would be my guess.

I have this exact same noise. I re-did my entire exhaust recently with a lift and heavy arms etc. Now i have this noise. Only under load. Did you replace u-joints? Did it work? Mine visually look good. So im confused.

You guys were correct again! The noise was a bad u-joint from my front propeller shalf (Toyota's name), so i replaced both! Thanks again to all that helped! Mud and its community is a great asset!
