I am setting up an Explorer rear and I'm ready to weld on the spring perches. I've read the information on pinion angles, and not only are there differing definitions of the term "pinion angle" (angle of pinion to driveshaft, angle of pinion to transmission output shaft, and angle of pinion to rear axle spring mounting surface, etc.), there are differing suggestions on how to measure and set this angle as well.
I have read that the stock Ranger pinion angle to spring perch surface is approximately 6 degrees. I have measured the output flange of my transfer case, and it is 4 degrees, which matches perfectly to the angle of my existing pinion flange, which is also at 4 degrees. This would mean the spring perches would need to be angled 2 degrees to add up to the 6 degrees I have read here and elsewhere. However, just eyeballing the angle on my truck, it seems the perches are angled more than that. I have a bone stock 2005 4x4 extended cab.
I can't pull my existing axle to measure the current pinion to perch angle before the other axle is complete and ready to bolt in, but I would be greatly appreciative if someone who has a Ranger axle out of the vehicle and an angle finder could measure and verify the 6 degree number.
