Ever since I bought my F-450 a few months ago it vibrated and made a noise.
I chalked it up to knobby winter tires and it being a 450.
I never drove it over 110 kms because it vibrated .

Yesterday I was going on a long trip and it seemed to get worse so I took out my hubs to see if that helped.
I leave them in usually all winter on the bush roads.

That didn't help and it got worse , very worse it started banging in the frontend , I pulled over but the highway was icey and busy so I kept going slowly looking for a place to pull off.
There was a load snap and a bang and the noise quit.

I made it to a driveway and pulled off and crawled underneath , the front ujoint/ball joint on the front driveshaft is floppy around barley hanging on.

So anyway I think that's been vibrating since day one and the loud cluck I heard was the hubs finally disengaging.
I think the hubs were stuck in and the driveshaft was still turning.

I made sure the driveshaft wasn't turning and carried on.
Went 700km and the truck drove like a new 1/2 ton.
I couldn't believe how nice it was to drive , it was smooth and seemed to even handle better.

So even though its going to cost $300 or so to fix its going to be well worth it.

 

Glad you figured it out, but what a way to do it! By the way, I love the '08-'10 450s!!

 

Sweet! Glad you found it...not the best way I guess but never the less...I'll have to check mine as mine vibes bad from 85 to 100 km but at 85 it feels like a wheels going to fly off! I just assumed it was a bad wheel balance but it maybe this as well.

 

Good find. Not ideal troubleshooting but sometimes the part has to fail before noise can be pinpointed.

 

This didn't turn out as good as I thought it was going to.
Its more than a ujoint , the whole end of the driveshaft is wrecked so need a new yoke and who knows what else.
Bought a driveshaft from autowrecker and it was almost as bad as mine.
Am getting a new yoke welded on another driveshaft now.
I can see its going to cost a bunch more than a ujoint..................

 

That really s*ucks.....would you just replace the unjoints then as a maintenance item now knowing what you do?

 

$850.00 and good to go again...............
