- During disassembly, note and record relationship of all parts to each other, especially clutch disc and plates.
- Mark case halves, pinion mate shafts, and their corresponding ramps. Mark differential spiders for reassembly reference. For front axle shaft and bearing removal, see articles on Spicer (Dana) Full-Floating Axles or 4-Wheel Drive Steering Knuckles in this Section.
- With axle assembly removed from vehicle, pull axle shafts out far enough to allow clearance for differential removal. Using a housing spreader, spread carrier.
- Do not spread carrier over 0.020" (0.51 mm). Remove bearing caps, and note letters stamped on caps and carrier. Remove differential. Mark bearing cups to indicate from which side of case they were removed.
- If not previously done, scribe marks on both halves of differential case. Place case in vise. Remove case bolts and disassemble case. Keep stack of plates and discs exactly as they were removed.
