When changing ratios on model 60 and 70 series axles, it may be necessary to change differential case along with ring gear and drive pinion.
1.Remove axle assembly from vehicle.
2.Remove axle shafts.
3.Remove cover plate and drain lubricant, then clean all gasket surfaces.
4.Remove bearing caps. Note matched numbers or letters stamped on the cap and carrier assembly. These numbers or letters must be matched during assembly. These numbers may either be stamped vertically, horizontally or in some instances both vertically or horizontally.
5.Mount Spreader tool No. TOOL-4000-E or equivalent onto carrier assembly.
6.Position a dial indicator onto carrier, then spread housing. Do not spread housing more than .015 inch.

7.Remove differential case from carrier, Figs. 1 through 5. It may be necessary to pry case from carrier with suitable pry bars. Use care to avoid damaging machined surfaces.
8.Remove and tag bearing cups to indicate which side of carrier they were removed from, then remove spreader tool from case. Model 60, 70 and 80 series axles use spacers installed outboard of each bearing cup, remove and tag for reference during assembly.
9.Remove differential case bearings from case using Universal Bearing Remover tool No. D81L-4220-A or equivalent. Place tool in a vise when removing bearing. Turn case over and remove other bearing in the same manner.
10.

11.
Place a few shop towels over a vise to prevent ring gear teeth from being nicked after it is free from case assembly. Remove ring gear bolts, leaving four bolts loosely assembled 90° apart. Tap each bolt head alternately with a rawhide or plastic hammer to loosen ring gear from case. Remove case and ring gear from vise. If applicable, use care not to damage exciter ring when removing ring gear. Whenever removing ring gear bolts, discard and replace with new bolts upon assembly.
