Rear driveshaft question
I installed a new rear d/s, with the rear axle turned up to so the pinion is in line with the d/s to stop vibration, is this going to affect the coil springs since the coil base is at an angle now? Being a newbie at all this it has me kinda worried about that and if the pinion bearing is going to get oiled good?
Take a peek at this thread for the springs https://www.jk-forum.com/forums/modified-jk-tech-2/new-rear-axle-coil-mounts-117307/. As for the pinion bearing getting enough oil, I am thinking that at the speed the differential turns it should sling the oil all over in there covering everything sufficiently enough.
I noticed you have a 4" lift so you have two things contributing to spring bow:
1. Without any parts to correct it, the natural tendency of the lift is to move the rear axle slightly forward and towards the passenger side
2. When you rotate the axle to correct the pinion angle the bottom perches for the coils are no longer vertical
You can use products like the bolt-on JKS spring mounts to correct for bow introduced by #2.
But to correct for the bow created by #1 you will need a complete set of adjustable rear CAs to push the axle towards the rear slightly and an adjustable track bar or taller track bar bracket if your lift kit didn't provide one.
