Not a happy camper right now:disgust:
This morning, I finally got around to re-installing my front driveshaft after replacing the TC end CV joint.
Everything seemed to go smoothly on the install. Went for a quick drive down by the airport to test it out in some sandy areas. No more clicking, seemed to engage and disengage with no problems.
Woohoo! Mission accomplished...........until we hit the highway to come back.
At about 60mph, there was BANG! and a vibration that would shake your fillings loose.
I quickly pulled over to the shoulder, stuck our heads under the Jeep and the brand new CV had shredded itself. Luckily, Jon had thought to grab the socket and wrenches, so there we were on the side of I-90 pulling the driveshaft back out. Which was definatley not fun with 18 wheelers whipping by a few feet away and scalding hot exhaust (I've got the burns on my forearms to prove it)
We found the head had come completely off the shaft, obviously shredding the boot and flinging grease all over. The outer circlip fell out in 2 pieces when we pulled the head off. Not sure if this is a cause or an effect.
Here's a pic of the CV.
The splines on the end of the actual shaft seem to look OK
Now, I'm no mechanical whizz, but it seems to me that a CV should last longer than 10 miles. So what did we do wrong?
Is is possible/probable that the new circlip simply failed?
Or could this be caused by not properly indexing the shaft to the flange?
Any other ideas on what type of bonehead error I could have made?
