Vibration when accelerating up past 40 MPH

Well I found some that are identical to the ones on my truck on Amazon with 2 day shipping. I just didnt know if it is just a matter of replacing that weight or do they have to do some computer work also?

 

Thanks for the reply csu hte only reason I asked if i could replace myself is due to the fact that only one square came off and the residue is still there to give me an exact location on where to replace the one square that came off. In my situation are you saying the tire is now in a imbalanced state and has to have all the weight's redistributed elsewhere on the tire?

 

The are 1/4 oz 7cm squares and I can clearly see it was only one due to the adhesive that was left behind..

 

Every tire has 2 rows of 7 squares from the look of this I may need to replace 2 and then maybe even HVAC tape all just to do it at this point.

 

yes. it literally would take almost nothing to throw your truck into a vibration like that.. which is why your wheels are balanced in the first place, and also why it only happens at a certain speed.. if your wheels had an "average" of 80 grams of balance weights each, and one of them lost one 10 gram weight, it would throw the balanced rotation on that wheel out 12.5% and the way that sound waves and vibrations work, when that "imbalance" reaches say 150 hertz, you reach the point at which the imbalance effects itself and you begin to feel it in your cab (the same way that your exhaust system with no resonators or x pipes sounds fine until it hits highway speed, and at 65 mph you get a drone sound that drives you nuts) ... its science. There comes a point where a "meaningless" problem like a vibration affects itself and multiplies to a point that it can't be ignored. often the solution is simple

 

like I said before .. and this is merely an opinion.. I think you should take it to a tire shop and have all four tires re-balanced. unless you need a new set of tires, in which case I think you should balance the problem tire and wait and have the new set balanced pre install... just my opinion but I'm glad to see that my original comment had validity and you've found that you've lost wheel weights, this is the cheapest fix available

 

Thank you for the break down 5ive7even, I am definitely grateful that you brought that up. I am new to doing my own maintenance on vehicles in general and I have yet to come across wheel weight's in general.

I'm just glad I found the issue or where to start! Thank you everyone who chimed in. I am also gonna let them look at my rotors and brakes just to be on the safe side have a good week!!

 

Hey guys, just a quick update. I took my truck to a tire shop, I got the tires rebalanced, after the rebalance the truck still has the same vibration between 50-65 mph (same exact feeling). this is starting to get weird because the wheel weight was off of the driver side rear tire.

I guess my next step is to look at the rear shoes like CSU stated earlier in this post. Once again to refresh everyone's memory the truck is not vibrating when braking it only vibrates on the steering wheel and all my driver's seat and my gas pedal between 50 and 65 miles per hour accelerating. Thank you for your time.
PS I talked to a local mechanic over the phone and explained to him my situation and he stated with confidence that it's the U joints. Has anyone ever heard of my specific issue being a U joint/driveshaft issue?

 

Yeah that would suck if it's the tires, I just recently bought these tires like 2 months ago. I hate to say this but I'm pretty sure the tire shop did not actually rotate my tires. The only tire that wheel weights were replaced on was the one driver rear that had wheel weights fall off. you can clearly see where they took the wheel weights off the rear left and replaced it. The other tires still have the old wheel weights and have not been touched. This is what makes me think the tires weren't rotated.

 

To be clear the only tire that was touched was the back left tire and it's still the back left. If rotated the back left should be the front right now correct me if I'm wrong but that's what I thought. I was under the impression back left becomes front right and back right becomes front left and the front tires go straight back

 

I'm no expert but I just got under here and one side of the ujoint looks damaged or broke to me. Can anyone confirm this?

 

I just replaced a brand new tire it was out of round not saying this is the issue but it could be I had to have it road force balanced just to figure it out.

 

Im gonna go to a more reputable place tomorrow and I've heard they can do road force balancing maybe I can figure something out there. Now I'm worried if that ujoint is broken/damaged on one side^^ pics above

 

they may have taken all of the tires off, put them on the balancer and found that the only one out of balance was the rear left.. then again maybe that was the only one they removed its hard to say

 

Not sure its hard to tell in the pics.

 

Yeah I thought about that 5ive7even, They really pissed me off and they are suppose to be best around my city. They didn't even rotate my tires like they promised. It took them 3 1/2 hours to do the job and I got done like that smh.

 

looks like grease on the universal. one part almost looks cracked but again, I think its grease. I would wipe the grease off of the u joint and drive shaft and see if you can see any cracking. part of the u-joint does look like its chipped away a bit toward the inside but like I said, its hard to tell from those pictures.

also check this out. the guys voice might put you to sleep but this is how you check a u joint to see if its worn out

Lol I watched that video earlier

That guy's voice made me cringe, but i'll watch it again and try to ignore his voice. I tried to move the drive shaft with my hands but it wouldn't budge. I didn't try the other methods.

 

the drive shaft will only move if the truck is in neutral and you have the rear wheels jacked up in the air

 

if you decide to do that, make sure you chock the front wheels so the truck doesn't run you over

a visual inspection might be enough though. wipe that grease off and give it a good look over. you can always grease it again afterwards if you're worried about not having enough in there

 

Yeah it definitely needs to be replaced. Idk if it happened during the whole "leaving the Ebrake on" dilemma.

I can confirm the Ujoint is damaged In the rear, I'm hoping my driveshaft is still in good condition if so it shouldn't be that expensive. Definitely taking it to my mechanic tomorrow. Crossing my fingers just want this vibration fixed so I can move on. Once again thank you guys for your time and helping me.

Thanks 5ive7even, I watched some safety videos before I got under the truck. I used blocks and some old tires to keep it in place.

 

Hey guys, Quick update I took my truck to my mechanic (been doing work for the family forever) he definitely confirmed that the rear axle Ujoint is damaged and is replacing it for me Thursday. I will give you guys an update on the vibration after I get the truck back Thursday afternoon.

I gotta ask, Was all this coincidence with the Ebrake being left on? Or can what I did with the Ebrake damage the Ujoint? Wonder if the Ujoint was about to go and this mistake sped up the process. Very weird situation seeing that I had wheel weights fall off as well.

 

I think it's probably a coincidence. I think the ebrake thing could have been the reason that your wheel weight fell off... if the brake was dragging, heating up your wheel and the adhesive let go and the weight dropped but unless the bearings in your rear axle flew apart then it probably had nothing to do with the ebrake being left on

 

Brad, just curious if the vibration went away after getting the Ujoint installed .
