Yea, I did a SYE and CV driveshaft when my DS flew off and took half the tcase with it.

And its not so the DS wont fall out, atleast not on a Wrangler. Its so you can have a longer driveshaft, which means shallower driveline angles, which means no vibrations. Vibes are a problem with lifts over like 3 inches and no SYE.

Also, I got my lights today. Still not dont wiring them up though.
