Too much grease on the splines?

It wasn't the splines that failed.

But the grease looks so fresh that I'd want to see if the u-joint hadn't just been apart and who did what with it.

 
Blue grease ==> definitely not HondaPro Moly.

Concur with Checkswrecks's implied remarks: suspect recent driveline work that was not properly re-installed.

I had a driveshaft break on a 61 Chevy wagon. Metal fatigue through the splined section. Fortunately, no one got hurt.

 
I know it isn't Honda Moly paste- I've spent enough time cleaning that stuff off my skin. I was just trying to keep it related to FJR's. OK, very loosely related.

 
Woulda been a real ***** on the bike.
You wrote what I'd been thinking. I have a 37 mile ride to work on everything from passing cows to the DC beltway. What scares me the most aren't the intersections, it's big stuff like driveshafts and having seen ladders come off of contractor pickup trucks. :ph34r:

 
I liked that the article stated the truck driver stopped at the scene. Yeah, no duh.

Welllll....that depends. If it was the jack-shaft between the two differentials (on a 3-axle truck) he still had power to one set of drivers. Of course, if it was the drive shaft between the transmission and the front differential...

Another case study in reasons many of us in the industry have continually warned:

Stay away from big trucks.

DO NOT ride in their shadow.

PASS them.

 
Being a Paramedic I would pull up to the scene and see that front wind shield. The first words out of my mouth would be.."wholly $h!t he's dead!!! The driver of the car is very lucky to be alive..

 
one our Houston local guys hit this on the freeway the other day and luckily all he did was bend a wheel on his sportbike.

Damned trash on the roads these days.

The Blue color you see is not any type of grease/lube, it is (from the factory) a synthetic/plastic like coating that is used for a anti seize type coating to reduce seizing of the shaft splines. That driveshaft ,with suspension travel must move in and out on those splines. there was a good closeup of the yoke on local TV and you could clearly see the crossshaft/needle bearing marks that WOULD indicate a lack of PM lube. Being a fleet mechanic this is a scary observation, as private indrustry is profit driven the term turn key and GO! come's to mind. I tell my wife constantly DO NOT! stay anywhere near any truck for any length of time. Be VERY careful out there!
