SO here's the symptoms during acceleration there is an occasional shudder, then at any deceleration(coasting), or braking there is grinding/grabbing, a pop, and then the Jeep feels like it is lurching/bucking especially 30mph to stop.

Jan 2019 Front brake calipers
May 2019 Front differential bushing all 3.
July 2019 4 days of wheeling at Disney OK SERVICE 4WD light came on, went off next time we started engine. Came on again on way home while pulling our camper. Our Jeep caught fire on the way home, power steering pump blew and hot manifold lit it up, got fire out, patched up and limped to next town. Put in new pump and away we went.
July 2019 Power steering pump, New gear oil(Royal purple) front diff, rear diff, transfer case(Mopar NV245) noticed excessive grease/oil PINION Seal FRONT Diff Leaking
Service 4WD light on and 4low will not activate
Oct 2019 The shudder, grabbing, started the driver front caliper was bad, replaced it. Last night the problems at the beginning of the post escalated and towed Jeep home.
With the Jeep now on the trailer I was thinking of taking it to the dealer and have them read the Service 4wd code to give me specifics on that. I do not trust them to fix anything, It cost me $260(labor) for them to put on a factory 7 pin tow harness that I provided since they were back ordered and couldn't get one for weeks. AND they wired it wrong, took me 2 hours on the day we were leaving on our trip to trace down what they did wrong and fix it. So hopefully they can at least read a code properly.
With the pinion seal leaking, and can feel it in the steering wheel and floor board I am thinking along the lines of CV or the whole diff needs rebuilt? but since I just did that brake caliper makes me wonder about other/more brake issues, or bad new caliper, brakes can do funny things and make you chase rabbit trails.
1) Go to dealer first about the code??, or Is there a way to check the bearing in the front diff to see if its bad without opening it up? Would a bearing throw a Serv 4wd light?
2) Can I remove the brake caliper, cap the line, and drive to eliminate that?
Other know issues driver exhaust manifold broken stud, bad cat bank 2 (efficiency below threshold) and bank 2 O2 sensor.
Sorry for the really long post but I would rather give too much info than, my lights on whats wrong kinda post.
