Need help with vibration
Hey guys this vibration is driving me nuts hopefully you can help 
It happens over 60mph. Can feel it in the floor and when worse up into the steering wheel. I have had all wheels balanced. Front end is tight. Bearings are tight. Checked steering box for cracks around mounting holes, all is tight and good. Almost feels like a loose wheel. Tires are new and rims are used. I'm leaning towards a square tire. I'm out of ideas hopefully you can help.

Re: Need help with vibration
could be the driveshaft or u-joints. a bad tire, a bent wheel, a bent axle, or a variety of other things.
if the wheels were balanced by a competent shop, though should have noticed a bad tire or damaged wheel

Re: Need help with vibration
tires are new but chinese which was why I was thinking it could be a tire. U-joints are fairly new about 1 year old. No vibration at any other speed could that still be driveshaft?

Re: Need help with vibration
ok what im sayin gis that its a front wheel bearing ihad the same isssue check them n see if thier bad if not its gotta be a tire or rim possible a bad internal part on your power steering but if it was power steering it would do more of a jump randomly them wobble or vibrate

Re: Need help with vibration
Check your front ties, they could be seperating & may have a small lump on the tire that contacts the ground. If you have another set of rims & tires for the front put them on & see what happens? Maybe tje driveshaft, their are weights on their also, might wanna check if any came off.
