Here is what I have got for replacing the rear diff in a venture van. Feel free to contact me with any questions and I will assist as best as I can!
Important: During the removal of the wheel drive shaft, the differential output shaft may become disengaged from the differential. If this occurs, firmly grasp and separate the output shaft from the wheel drive shaft. Align the splines on the output shaft to the differential and reposition the output shaft to the differential.
Simultaneously guide the left wheel drive shaft onto the differential output shaft while positioning the differential assembly to the suspension cradle.
Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
