Hello, what size is your tryck and is it 4x4?
Also, are you removing the entire rear differential or just the insides?
Below is disassemble. be advised, this job requires special tools. I can only suggest possibly some help with this or possible reman or used unit? I am not saying you can not do the job but... without the tools etc, you will be unable to 100% do the job correctly
Assemble coming in next post
IMPORTANT: Tighten the ring gear bolt in stages in order to gradually pull the ring gear onto the differential case.NOTICE: Refer to Fastener Notice in Service Precautions.
