[QUOTE="centuryhouse, post: 451696, member: 23848"] 2015 Rubicon JKU 4" lift, 35s 65k miles I got this JKU this summer and just noticed the front driveshaft had a lot of slop so replaced it with a double cardan shaft (single u-joint at front differential, double at transfer case). I installed it yesterday and now have a mild vibration at 55mph that gets more noticeable the faster I go. Everything was tightened to spec, greased, and feels solid. Reading revealed the pinion must point to the transfer case with this style DS and mine does not. - Adjustable lower control arms should allow me to point the pinion up - is that correct? Or is it uppers that are needed? (Plenty of room in wheel well for travel either way) - How does changing pinion angle impact the castor measurement? - If I get adjustable CAs, do I just eyeball the pinion to point to the TC? Is more precision needed? [ATTACH type="full"]122461[/ATTACH] [/QUOTE]
