Sounds silly I know. But this night after some testing on the road I heard sound like smth. small fell off, stopped and saw huge bolt on the road. I don't remember seeing such bolt anywhere. K-member bolts are similar size but it's not one of them... It was 5am so I was dead tired and couldn't return to base to check everything...
Help!

Wow,that is a generic Gm bolt that fit in any of a dozen places.

I don't think it was anywhere in the front suspension. Although, the bolt was hot when I picked it up, so might be from the front still. It has that large plate under the head that is almost 2" in diameter, not very common...

Check your k-member as that looks like one of the 6-8 (can't remember the exact amount) that hold it to the body.

Torque arm bolt?

How long is it? Hard to tell in the pic, but that almost looks like a brake caliper bolt or something else in that general area. Could explain why it was warm if it came from near the wheels

Check your balancer bolt.

Vetal

is that even possible???
Bacon: it's about 4" long, 14-16mm diameter

Yes DEFINATELY the balancer bolt. DO NOT drive the car anymore till you confirm that it does or does not have a bolt in the balancer. A balancer coming off while the engine is running is a very bad situation.

Do they fell off like that? :O :O :O In Nissan world it's hard to even loosen that bolt, and GM bolts fall off by themselves??? I just wonder how does that pulley still stays there

thats what it looks like to me too...........check it before you drive it again.

have you changed balancers or pulled the old one for motor work in the past?

you should always use a new bolt on install or restall.

it might not of been torqued to speck on install or the pulley was never on 100%.or some one reused an old bolt.....thats a couple of reasons they fall out.

good luck!

New bolts and red loctite.

Vetal

iTrader: (3)

Is new bolt really that necessary?? I don't want to be off the road for 2 weeks just for the balancer bolt

Definitely a balancer bolt. I would put a new balancer bolt in with some red Loctite and tighten it down with an impact and you should be good to go. Your local GM dealership should have that bolt in stock so you shouldn't have much down time at all.

I don't have GM dealership as such everything must be ordered, 1.5-2 weeks wait time...
I just wonder what's the need for new bolt for such a thing? It's not head or bearing caps where torque is crucial...

Vetal, a few very capable people have said you need a new bolt... for the amount of catastrophe that could happen IF that bolt failed after re-installation... I'd say it's worth the wait and minimal cost to do it right and have that piece of mind. Just my $.02...
