Hello, I am new to this site so I hope I’m doing this right. I have a 2008 Silverado LT crew cab. When I slow down it “shudders” and then stops. This only happens when slowing down though. I have had everything to do with the brakes replaced, pads, shoes, rotors, all of it, and still same issue. I went to get new tires recently and found out the entire front end was totally shot out. I replaced all control arms, Pittman arms, etc.. anything to do with the front end is brand new. Still the same shuddering when slowing down or stopping. After several thousand dollars in work on her, still same issue. I was told recently that it could be the steering wheel position sensor but I’m not sure. I was only the second owner of this truck back in 2012 and baby her more than I do the wife and kids but I’m lost at what my issue may be. Any help from you guys would be GREATLY appreciated.

What'* not new? ABS module? Not that uncommon a problem.
That'* assuming you are braking.

I have never had any issues like this so it’* obviously new to me. Can I replace the ABS module? And yes, I am braking at the time it occurs every time.

I was referring to parts. Seems you threw about everything at it. The module can be replaced.

Is it something that someone with little mechanic skills can easily achieve?

All of these parts that were replaced . . . was it done by you or a mechanic?

Who was the mechanic (like what is the business name etc.) ?

How many miles on this vehicle?

Was an alignment done after all of the front end work was done?

Have you replaced the tires yet?

Does the shudder vibrate at the same rate as shaking up a bottle of salad dressing quickly? . . . or is it more like the rate that a paint shaker shakes up a can of paint at Home Depot?

Does braking cause the car to meander left or right?

Does the shudder cause the steering wheel to feel like it wants to shake its head "no" at the rate of the shudder?

Good morning, Okay, to answer your questions;

1. All parts were replaced by a mechanic. An ASE mechanic friend of mine has been doing so for 40+ years.
2. The mechanic is very reputable and in the rural area I am from. I have found that most of the reputable ones are from rural areas.
3. My truck has 178,000 miles on it. I am the second owner and the truck is in excellent shape, mechanically and visually. except for this issue that recently occurred.
4. After the entire front end was replaced, yes, I did have the alignment completed and then the new tires were replaced.
5. And yes, the shudder vibrates at the exact same rate as if shaking a bottle of salad dressing, very quickly. it has, however; become more prevalent recently, meaning that the shuddering can also occur when I am coasting very slowly as well. It is a quick vibration though and then when fully stopped it ends. Definitely not prolonged like when shaking a can of paint though.
6. When braking, no the truck doesn't pull either way at all. It did do this prior to the front end being replaced but doesn't do it anymore at all. My mechanic said to attribute that to the blown front end.
7. And lastly, no, the steering wheel doesn't respond at all to the shuddering. It is a very quick shudder and the quicker I hit the brakes the faster the shuddering ends.

So this shuddering only happens when the brake pedal is applied?

It was only happening when the brake pedal is pressed, however; now when you hit the brake and slow down to a coast it is doing it as well until you come to a stop. Sometimes when I press the brake and am slowing down it will do it rapidly and then if I hit the brake again harder it will stop as I’m coming to a stop. But generally it’* only right there at the end when I’m braking.

I've seen this before. If you can find someone that has a scanner that can read ABS codes, please do. I recall someone else on here having the same issue and it ended up being a tone wheel or one of the ABS wheel speed sensors. Again, get it scanned for ABS fault codes. Those pocket scanners won't do ABS.
