I've spent the last month working on the XJ but the only thing I've changed on the driveline are the leaf shims(2°-4°). Driveshaft is 12.5° and pinion is 9.5°.
I've been searching for a cause of vibration that started at 15mph. Found a bad front hub assembly and replaced that. Now I get vibrations at 40+. They are speed related and happen regardless of gear and throttle position.
Looked further and found 2 of the caps on the front driveshaft were seized up. Pins are still intact but there is no grease and rusty dust. What are the odds that the u joint is the cause? Where else can I look? I'd post pics but the app doesn't like quality photos.
