Bumpy Ride when accelerating and breaking

[SlippytheDisco]

Hello everyone, my 2004 discovery 2 V8 started experience mild bumpiness when decelerating yesterday while getting off the interstate. This symptom has only worsened in a day, turning into a noticeable bump to the acceleration (20ish to 40ish mph, and by bumpiness think of having a square for a tire), and then after 40mph it transitions to a rattling throughout the vehicle, and noticeable shaking in the steering wheel the faster I go. It’s sometimes more pronounced in a deceleration/acceleration loop, however it is always there. I am just wondering what I should check, and in what order. I tightened all the lug nuts when I noticed it yesterday, but have not had a chance to do anything else. I know this is probably just a general car question, but didn’t know where else to ask. Thanks!

Threw a wheel weight? Tire delaminating?

Ok cool, I will look into it. Pretty crazy if throwing a weight can cause that much of an issue lol insane how vehicles work

Shack the front driveshaft to make sure its tight.. Possible it is about to explode.. Or look around wheels for a shinny spot where a weight was..

Ok awesome, thank you. Is there anything else afterwards that might cause this if everything seems to be fine with the weights and driveshaft?

Steering damper or stabilizer?

Check ALL U-joints on driveshafts? Rear Ball joint on the top of axle? Wheel bearings?

I found a sticker residue that looks like a missing weight on my back left tire, so I’m hoping that’s all it is. I have to repair an 02 sensor, so I’m going to take it to a hobby shop to check everything y’all have said anyways, better safe than sorry. Thanks for your help!

This doesn't sound like a wheel weight to me. Go back and check your drive shafts. If the front lets loose while you're driving it will take out the transmission.
Don't just reach up and twist it, remove them and check if you have free motion throughout its range.

Sounds like a a front prop shaft to me too.

Death wobble? Worse when it its a bump?

I was able to get it on a lift today while replacing an 02 sensor. Turns out it was a warped tire, hard to tell until I had it up on a lift. Thanks for the help!
