Driveshaft fell out on the freeway!what's vibrating? help!

[Problem2420]

Hey guys well my u joint popped awhile back so I replaced it, but I was driving on the freeway the other day and had to a vibration and thought I need to get to that later. Then I decided to pass a car and it got violent. Decided to pull off and before I got into the emergency lane the drive shaft popped out. Long story short got it towed home replaced the u joint but the truck vibrates at 10-15 mph So I'm wondering if it could be the yoke of driveshaft. Any help guys please.

Oh and the truck never use to do it until 65-70mph

if it actually "fell out" theres a good chance you might have knocked it out of balance.

I'm with this guy.

yea I would have the thing checked for balance and straightness.

 

[DRAGGIN95]

Yeah I agree, I bet it's out of balance.

So if it's out of balance should I get a new one? Or could it be rebalanced like tires. If so were? Thanks guys that slipped my mine I was just looking at physical appearance.

you should be able to go somewhere and get it checked. not exactly sure where.

Any driveline or transmission shop should be able to dynamically balance it for you. Shouldnt be more than about $100. A friend got a driveshaft for a Jeep shortened and balanced for less than $150 so Im thinking about 100 for just balancing.

Thanks again guys finall got to call a few transmission shop, while they don't do them they recommended me to a shop around my area. Called and they said about $90. While Its not bad I'm surprised that I could only find one shop so far that had the machines to do it
