ALL MEMBERS! Please Read, IMPORTANT!

I had a really bad scare today. I've been chasing a slight driveline vibration while coasting and thought it was simply time for u-joints. While I was underneath the car changing the clutch master cylinder I happened to look at the driveshaft.

1 bolt was MISSING and the other 3 were all backed out!

I have NO idea how this happened as they were all torqued-to-spec with a 2-year old Snap-On torque wrench. It really freaked me out that I was THIS close to having a driveshaft disconnect.

PLEASE, go check your cars. ESPECIALLY if you've ever had to pull the driveshaft for any reason. Mine was last out 10,000 miles ago!

I am now adding the driveshaft bolts to my 3,000 mile checklist (Change oil and filter, check air filter, check brake fluid, check clutch fluid, check belts, check hoses, check coolant, check lugnuts, check driveshaft bolts).

Good call Mike. Glad to hear your ok and so is the car. Mine was last out when I did the flexplate change. And though it's not driven, I'll go check for sure

uh, ever heard of "loc-tite"? that's what the factory uses, and should be applied EVERY time you pull the driveshaft off. ring gear bolts should have some type of thread locker, too.

yeah I had that happen.  Lost two bolts though.  Use lock tite.  that is the only way to be sure they will stay in.  especially if you drive it hard like I do.

And HOW many people told me I was foolish and wasting my time to loc-tite my DS bolts?!

This may sound stupid but at 80km/h my steering wheel shakes, it stops when I get to 85. So could that be the result of a loose bolt?

no, that's more likely your front tires being out of balance.... if you go fast enough, even an out of balance tire will stop shaking..... any type of rear end or drivetrain vibration should be felt in your seat, not in the steering wheel

Thanks, I just had a tire mounted on the rear rim but I guess they were too lazy to balance the fronts. I even paid 30 bucks. :beatyoass:

Witch loc-tite did you use? Green? Blue? Red? I've used the red and the blue. The red stuff is for stuff you don't want to come apart. The blue is if you want to take it apart again. Not sure about the green. I always check that when ever I'm under the car. I'm already there and it only take a couple of minutes.

then maybe you didnt use enough, or prep the thread surfaces correctly. ive never had a problem using loctite, and why didnt you mention that you actually used it in your 1st post?
