Hi,
I've taken some measurements of the rear driveshaft
An angle meter places on ... reads
Transfercase output yolk 9 degrees
Driveshaft 10 degrees
Pinon yolk 12.5 degrees
I am having some trouble truly interpreting these numbers. As I read them, it would suggest the front u-joint is running at 1 degree and the rear at 2.5 ? And with torque on them, the rear would actually be about 4.5 (adding 2 degrees)? Wouldn't that mean that the rear pinion should be reduced by 3.5 degrees to 9 degrees? Or 5 degrees to 7.5?
I am wondering if the pinion is "too high"? The higher you turn up the pinion, the less oil you get in there and the less ability there is properly lubricate the pinion bearings. What is the practical limit for a 8.25 axle?
The transfer case drop will be replaced by a SYE and the rear axle reshimmed as necessary. Here I'm looking for some knowledge and education about what I'm starting with.
