Changes, Reduces, the angle of the engine and transmission, which in turn changes your pinion angle (increasing)at the TC output shaft. Without an SYE it will increase the degree of angle at both the tc and pinion, potentially creating or reducing the angle on your U-Joints, Which may or may not create a vibration. Everything is relative to the lift in the rear end springs. But does reduce the angle created at the engine mounts with the TC drop. YMMV.
Pay close attention to any vibrations you may feel at different speeds both before and after removing them.
That and their ugly cheap lookin. Pulled them to find their poly or plastic of some sort. I didnt even try to drive it after measuring the DS angles without them, to steep and 5 degrees difference, Ah well.
I didnt even measure the DS angle itself as it looked pretty steep. My concern was in the difference between the 2 yokes. IIRC a couple degrees difference is acceptable, but I was 5+ and figured U joints would go quick. That and the yoke was pulled out further than I felt OK with and it was a little loose in the splines. I really would like to do a SYE but its not in the budget any time soon.
