Some of you have experienced the universal joint coming loose on the steering shaft. The universal joints are supplied to us with setscrews. Vibration will cause the screw to back loose. We installed them with red locktight from the shop but if you check them or move the setscrew the locktight is no longer doing its job. I stumbled across a picture of Hyper Racing's house car. Take a close look at the picture. They replaced the setscrew with a socket head cap screw and used a thin jam nut to clock the bolt down.
I highly recommend you doing the same.
Hardware needed for the fix-
1/4-28 Socket head cap screw (3/4-7/8" Long)
1/4-28 thin jam nut
You need 8 total.
Hope this helps and if you cant find them locally let me know and I will gladly ship some out.
