Your profile states Ramey Pa., Is this where the jeep is located?
I would recommend pulling the axles and do them on a workbench it is a lot easier then laying on the ground and give yourself plenty of time to do them correctly. Another idea is to get a free axle and set it up a few times, this really helped me do mine.There is a lot of info on the web but every thing you read in NOT always correct. It is not rocket science but has to be done right to be strong, quiet, and last a long time.
