Totally doable in place. It’s not that big a job. Getting the drive shaft out was probably the hardest part. My little electric impact made short work of the housing. Just had to clean the sealant off the surfaces then reseal on the way back.Thanks for the photos! Looks like a lot more work than the speedo gear was... grrr. Good call on the tail shaft seal as mine leaks a little anyway.
Did you have to drop the tcase or is it doable in the pickup?
