We all know that the factory front Rzeppa joints are the weak spot in the driveline and are subject to failure. Teraflex makes a replacement joint that can be had for about $190. It is the same joint that is used in the JL an JT. While searching for alternatives I came across a replacement Rzeppa made by Crown part number 68272524FRK. Summit Racing has them for $89. Worth keeping one on hand at that price. https://www.summitracing.com/parts/cwa-68272524frk
