Steering Linkage Failure

[Lickity-Split]

On our race car, we use splined shafts and Ujoints. But instead of using set screws, we drill a 1/4" hole all the way through the Ujoint and shaft. Then we run a 1/4" grade 8 bolt all the way through with lock nuts. It's not going anywhere.

Actually, the Burgeson telescopic shaft requires a hardened bolt though the 1” DD end. My issue was when you added the larger diameter shaft to the assembly, that extra 1/4 inch threw the firewall steering joint into an angle greater than 35 degrees which instantly cause a bind in the joint. I am looking to do exactly what you are describing on the rack input shaft. Problem is I just move everything to the next steering joint up the line. What is the diameter of the splined shafts you use?
