Brake Noise?

[Texas_Lone_Ranger]

Ok - I get that ABS is possible. Any way you could suggest to test it? I'm pretty anal about maintenance and flush my brake fluid every few years.

It's just your ABS kicking in and working, mine does the same with a little bit of Peddle pulsing.

Could it be the torque converter not unlocking properly?

Just replace it since it's the easiest and cheapest fix........

Loose nut behind the steering wheel?

Sounds like a bushing to me.

Bad u-joints will often make themselves known on deceleration. Had that happen a few times.

I have seen that as well. Generally, if you feel it in the seats and body it will be drive train or body related. I would look at u-joints and for any split or loose bushings on sway bars and control arms.

I'll get right on the torque converter - LOL. I'm pretty confident it isn't body/suspension related because it is wheel speed dependent. I eyeballed stuff yesterday when I was messing around and didn't see any issues with my sway bar bushings, endlinks, etc. Of course, today it didn't do it going to work. I'll check out the u-joints when I get home.

I think your truck is too early (year-wise) for it, but there’s TSB 14-0090 for drive shaft slip/bump. A pretty common occurrence.

It seems that only happens during acceleration, unless I read it wrong.
His happens while braking.

ABS, final answer for the red corvette die-cast.

I asked earlier of some way to test what you're saying because it certainly doesn't act like ABS. I've only had the ABS come on a few times when I was braking hard on gravel, etc. It pulses the brakes many times/second. What I'm talking about is much, much slower and definitely related to wheel speed, which to the best of my knowledge, ABS is not.

Anytime the ABS sensor detects a mismatch in speed between any of the 4 tires, it will activate, at any speed. Mine does '11 Expedition. Usually coming to a stop or slow turn, one wheel slips and the ABS kicks in. It's abrupt and recognizable that I think something is broke. Have you pulled any codes?

Try a break job, it will only cost about 150 dollars if you do it your self. I was getting a lot of wobble when breaking and turned out the front break rotors were warped so replace them and the pads and the problem went away

 

[cycleguy2300]

Would putting it into neutral while braking stop the thump from the u-joint?
Just as a test?

It might or might not. The u-joint will still rotate thank to the diff, but it shouldn't be under any load to speak of.

I'd rather climb under with a light and take a look assuming I wasn't diagnosing a fresh symptom while I was still moving.

I did get under there. Put it in neutral with the parking brake on. I yanked and pulled on the driveshaft and the u joints seemed solid. Of course, the noise hasn't happened again.

 

[TxStetson]

One thing nobody has mentioned yet. Is this a 4X4 with IFS by any chance? If so, check your CV joints. They usually make intermittent noises before they try to take the steering wheel away from you.

 

[robertc1024]

2wd. I know the dreaded CV joint clicking all too well.

 

[jrbfishn]

Front sway bar bushings or worn shock bushings will sometimes do it too.

It's probably a 223 shell stuck somewhere it shouldn't be.

EUREKA! That must be it, or a 17 HMR, or 6.5 CM or ... I keep finding those in strange places for sure.
