LIfted trucks running an NP208 - drive line angle? - 10/19/13 03:32 AM
I am not really sure where to begin here so please bare with me.
I have a short box W150 with a Dana 60 swap in the rear and GM 8-lug/disc brake knuckle swap on the D44 up front. It has a 4" all spring tough county lift and 33x11.50 tires. So far I have blown up two constant velocity joints in the front drive line. The last time it happened the drive shaft took out the passenger side exhaust and almost stranded us in BFE on in a remote canyon between two mountains. After this experience I have decided that CV joints are unreliable. \
I never really gave much thought to the why's of Dodge using the CV joint in the front drive line until I started considering that the t-case yoke angle had to point up in in order for the rest of the engine/trans/t-case to be down tilted for the rear drive line. Do I have a chance in hell of making this work without a CV joint or swapping in a 203 t-case? It looks like if I shim the t-case mount to get the front yoke angle level or the rear output from the t-case will also be level. FWIW from the factory it measures 3 deg positive vs the +2 deg on the front diff yoke. I am kind of stumped here. Am I missing something when it comes to making the CV joint last in this application?
Sorry for the likely confusing, long post but I am kind of at a loss here.
