volvo d13 2009 vibration and shaking

Hi
I have volvo d13 2009
And when is on cruise around 1400 rpm and up, i see how is moving up and down
The truck start to shake to have vibration ans i feel it in the back,i check the injectors no codes, change the filters, balance all tire
Balance the drive shaft, still the same problem and dont have any smoke or hard start in the morning the idle is good.
Thank you!!

 

Did you check the carrier bearing mount?

Check or replace rear shocks.

Out of round tires.

 

I change the carrier bearing and still the same
Replace the rear shocks still the same

 

Ujoint issue? Drive shaft out of balance? Drive axle not angled right due to ride height? Out of round tires? Bad hubs? 3axle alignment was last done when?

 

Did you check and verify the rear suspension ride height is correct?

 

If anyone could help me please having hard start when truck sits for about 15 minutes takes about 5 to 10 seconds to start the truck when the truck starts runs okay no idle problem and fule milage is good as well was told 6 injectors are bad with a bad fuel housing as well could this be the problem really and just did the injectors about 140k miles ago

 

Fuel and injector issues can cause a vibration. Probably an injector or two not seated in the injector cup correctly. This could cause a vibration and a hard to start issue.

 

I have no vibration at all just if I leave the sitting for about 15 minutes takes few seconds to start like 7 to 10 them it start up no idle problems at all normal idle and fuel mpg didnt change pulls fine every gear

 

7 to 10 seconds before it fires up is a little too long for that year. I would take it to the dealership and have them run an air in fuel test.

 

They did and that's what they gave me the injectors and fuel filter housing this thing I dont understand I know the injectors go out on the volvos but I just had the new version installed like 140k miles ago and now they are all bad
