Bolts BACKED OUT of REAR END! PICS FIX
the other day, i was pulling into the parking lot, and my car started making loud noises from the rear like something was hitting something… i stepped out of the car, looked under the car the best i can, as it was prob 100 degrees outside here in TX, i had my girl drive it back and forth and i can pinpoint the noise to the driver side rear of the car, i knew it had something to do with the drivetrain b/c it only made the noise when i was in motion, and i found a long bolt with grease like material on it, i was hoping it wasn't from my car, i called my buddy scooter (spdrcr771) and he said the bolt was def a rear end bolt as i described it to him, (it was the 6 bolts that bolt in from the rear end to the axle)
LISTEN TO THE VIDEO
i call in sick to work b/c my car is my baby and i want her all better… SORRY FOR THE LONG STORY… NOW ONTO PICS!
see that piece hanging, that's what was making that noise as the wheel spins, it was hitting the bottom of the car
I had the rear end installed by DYNOSAUR PERFORMANCE, 4.27 LSD :-), and apparently locktite wasn't used on the bolts, now idk if it was necessary but it sure would of helped lol, i also think the grease dripping down or whatever it is may have helped the bolts back out b/c the grease is all on the bolts on the thread too.. so i loosened the bolts by hand.. and one is missing, idk if it was missing from the beginning though, put locktite on them and bolt them back in, everything is A-OK
DOES ANYONE KNOW WHAT THIS GREASE IS FROM….

Lol. Yeah, it never started as a small sound though, you'll know if they're loose but it wouldn't hurt to look..
If anyone has any idea from what exactly that grease is, it's coming straight down from the driver side of the car above the rear end, thanks
And my apologies for the photo size, it's iPhone quality lol

"Locktitie" (treadlocker) is not specified for that application, just a proper torque. All is needed.
You should add the molly grease to the joint to replenish lost one tho.

I didn't use lock tite to put them back in. Just even pressure.

Dude,
The bolts were obviously not torqued properly and likely installed 'dirty', in other words, no cleaning done to them and the thread surfaces. The 'technician' probably just hand tightened them. Sadly, most garages don't torque anything to specification, they just 'go by feel'. To clean nuts and bolts, then torque them to specification, is too time consuming for most shops, even ones with good reputations; this is why I do my own work. For axle bolts, the common 'correct' practice is to clean/degrease everything, apply a bit of blue loctite, then torque to specification. The loctite is your insurance policy and is a smart thing to do. If you can't torque to the specified value then you MUST use blue loctite on a clean surface; otherwise you risk seeing exactly what happened in the photos.
