I installed the shackles and now have the driveline vibration at low speeds. I searched and found only one mention of the drive shaft length for a V6, auto Trooper (4 door) first gen. This length was 42.5" from flange to flange. Now, my understanding is that the measurement for length should be taken from the back of the u-joint cup on the output shaft to the same location on the pinion. Is that correct? OR, does anyone have the proper measurement for the above application? The post regarding the 42.5" did not mention the exact measurement process resulting in said length.

I have to remove and deliver my drive shaft and provide the dimensions for them to fab up the new one.

am I trying to make this more difficult than it should be? <img src="/forums/images/graemlins/confused.gif" alt="" />
