#1

i have a vibration that starts about 45mph.“When i put it in neutral it still vibrates”. I did check the universals. Rig has 195,000 miles on it. Manual trans. It must be lifted because im running 265/7516s on it. Ive been busy changing fluids and such so i have been underneath it but didnt look for lift or factory.


#2

It almost feels like the vibration is right underneath me and kind of shakes the whole vehicle. But i understand driveline vibrations can travel…


#3

Did this just start?? Anything change recently??

Vibration causes can be many different things…Tire out of balance…Ball joint…

Do you feel it in the steering wheel??


#4

I just started driving this rig
I understand vibrations can be hard to find because of many different possibilities. Thats why im hating it
I bought the tires mounted and balanced but will be changing to new wheels and tires soon.
Current could be out of balance for all i know
I CANNOT feel it in the steering


#5

Try rotating the tires to see if that changes anything? If it is the tires the vibration will still be there…but it may seem to move (like to the front).


#6

Sounds Good. I Now remember doing that previously and the vibration actually all but disappeared

Thanks

On a different vehicle…

I have a 1999 4Runner, 4 cylinder with standard transmission. In 2006, I had a vibration issue which I could distinctly feel in/under the driver’s seat. I apologize for not remembering all of the “symptoms”, but the solution was to replace the universal vibration damper - which is practically centered under the vehicle.


#9

That was my suspicion. It feels like it right under me but make the whole rig vibrate.

Cool

Thanks

You dont mean the harmonic balancer?

I google universal vibration damper and it gives me harmonic. I was thinking the big double universal joint thingy
