Highway vibration

[nitris]

My trucks is vibrating at 65+ miles and hr... I can't pinpoint what it could be.... I have brand new not even a month old tires,alignment, new sway bar bushings and sidebar bushings... anyone know what may can cause this? it rides real smooth until 65 and I don't feel it in the steering wheel.

Could possibly be an out of balance driveshaft.

Does the vibration go away at higher speeds than 65? If so, it is most-likely the tire balance. Move the front tires to the rear and see if it goes away.

It does go away some... I figured they were balanced when I got the new tires and the alignment after I did the bushing change

Was it there before you got the new tires?

If not bring it back and ask them to re balance the tires this time ask that they use 1\4 Oz weights if required.

Or do a High Speed balance. It's just another setting on the balance machine.

Most places I've seen don't put them on larger tires.

1\4 Oz weight will might make a big difference.

I did tires in a local shop for over 10 years. That's how I know.

Yea it did it before the tires... they were all mismatched and old... with the new tires it isn't as bad... so I'll start there since i Bought the warranty and it would be free

Some places also balance them so they're 'close enough'. They might also just be tough to balance. Hard to say whether it's incompetence or luck of the draw. You might take them to another tire shop to have them verified.

Aside from that, worn suspension components like shocks, ball joints, tie rods and more can cause vibrations.

Also learned way back when that all tire have paint dot or a sticker on them somewhere.

The mark on the tire always lines up with the valve stem.

The tire usually take the least amount of weight this way.

I don't know if my tires had a dot... I can't remember and don't see any... I have good year wrangler armortrac tires 235/75/15 I do need shocks though... That's next on my list
