It takes five minutes to plug weld them. It's a no-brainer for a fail-safe joint. It's best practice, and it results in a joint that's an order of magnitude stronger than without.
And yes, I have seen them tear out, and it breaks all kinds of shit when it goes. The driveshaft and the coilover shaft are the first to go.
Don't be a bitch about it. Just toss them in the drill press and fix it.
After a few long night and a full day today. We have a full roller.
If all goes well Jack will be taking this home next weekend.
