Got a question. I bought a RS5000 (RS5404) for my 2001 2500 4x4, and it came with a fitting to insert into the tie rod tapered hole.
The "nut" at the big end of the taper bottomed against the tie rod, and there was easily 0. 100" play in the taper. It seems that the taper was correct, it was just too short.
I've a hunch my tie rod is different from yours, and I'm hoping you can tell me how yours fit. I imagine that when you torqued the castellated nut, you still had room between the tie rod and the "nut" at the big end of the taper.
