Truvi might be able to weld those tabs up for you!

Alex putting in work for the channel this man cares and ain’t lazy!!

[yuma]

I am totally amazed at how calm and analytical you are in this video. Definitely a tragedy. I know stuff breaks, but seeing this scares the hell out me!

[robhunter]

Thanks for the update. Glad you did not get hurt. Getting the parts welded, whether MIG or TIG will be tricky with the motor in. The parts must be extremely clean to get good penetration and strength. Looking forward for more of the repair on Donny

Learn something new every day from this channel. Who knew the driveshaft can be used like a reverse impact gun.

*celebrates 47th birthday * * pusshes 3600lb car into garage to take out a 150lb trans that was just put in* You live the life, Alex!

[dominiczanella]

Things happen and it goes to show even the smallest part failure can cause damage to other components. You were pretty lucky and count your blessings. Those of us that work on our own stuff have to have the skills and know how to make good solid repairs when needed. I love that you do your own wrenching and show it on your channel.

[Joebauers]

Man i wish i had your motivation, really props to you alex.
Welding cast aluminum going to require a lot of faith in the person doing the welding.

That extension reminds me of the gun the judge used in who framed roger rabbit, or whatever movie it was i can't remember

[Beliefacy]

Setbacks are a bummer. We enjoy the journey & expect the "bumps in the road!"

[voodooreddevil]

Those clips that retain the u joint never go bad unless installed improperly. The clips that is😮

Keep grinding Alex. Love these videos. Wonder if Jake or any of the Lunds have any theories as to why that driveshaft failed like that.

[InFamousAlex]

Just your luck!! Took it with stride and got a pretty informative video from the carnage 💪🏼 Nothing but good things to say about the QA1 CF driveshaft with 900whp and aggressive road course/track driving. Definitely gives some peace of mind having it as a fuse vs having it tear anything else apart.

[billymania]

I love these YouTube car guys. They do crazy shit for clicks. They beat on their cars and blow things up. Occasionally we learn things!

[vigg]

Hey Alex take a look at the aluminum motor mounts that are bolted to the block make sure those are ok. They probably are but might be a good idea to make sure

[kylecurry]

You're a beast dude 💪...guy pushed a 3500+ lbs vehicle (with questionable elevation between A to B) getting it in his garage.

[Smasher-Devourer]

I believe all of the mounting points for the starter are on the bell housing. I mocked up my starter on my 6R80 a while ago to see how it mounted up. All of the mounting holes can be seen in the shim plate. I'd still weld all of those pieces back on anyway.

[killercoyote]

Mmr makes some braces that go from oil pan to the lower shield bolts on trans. Adds two more bellhousing bolts. I’ve welded ears back on with the braces and it work good

[Marcus]

I'm sorry you had this bad luck Alex. This really sucks. Maybe take off the flex plate just to make sure there's no other damage - the welder will probably want it off too. Keeping my fingers crossed that the repair cost is as low as possible.

The driveshaft looks like there’s no room to compress in that expansion part. So if the driveshaft couldn’t compress, if you hit a bump, suspension compress, weight from the force of the car going down could have damaged the u joint. Could have crushed the bearings and the centrifugal force fling the cap off, vibration, and then just how you described that violent vibration causing the carnage.
