Standard Differential

Fig. 2 Exploded view of rear axle assembly. Exc. Chevette, 1000 & Corvette models:

1. If side carrier bearings are to be replaced, remove bearings using suitable puller.
2. On all except Chevette and 1000 models, remove differential pinion shaft lock bolt and the pinion shaft, Fig. 2.
3. On all except Chevette and 1000 models, remove differential pinions and thrust washers, side gears and side gear thrust washers, noting installation position for assembly. Keep thrust washers with respective gears.



4. On all models, remove ring gear bolts, then the ring gear, driving ring gear from case using suitable drift and hammer. On all except Chevette & 1000 models, ring gear bolts have lefthand threads. Do not pry between ring gear and case, as mating surfaces will be damaged.
5. Inspect components as outlined in ``Cleaning and Inspection'' and replace as needed.
6. Install thrust washers on side gears and mount side gears in case. Lubricate all components with specified gear lubricant prior to assembly.
7. Position one differential pinion (less thrust washer) between side gears and rotate gears until pinion is directly opposite case loading opening.
8. Install other pinion with pinion shaft holes aligned, then rotate side gears and ensure that pinions align with shaft openings in case.
9. When pinions are properly aligned, rotate pinions toward loading opening just enough to allow thrust washer installation and install washers.
10. Align pinions with shaft opening in case, insert pinion shaft through case, install new lock bolt. It is not necessary to torque lock bolt at this time.
11. Ensure that ring gear and case mating surfaces are clean and free from burrs, mount gear on case, install 2 new retaining bolts at opposite sides of gear and alternately tighten bolts to draw gear on case.
12. Install remaining ring gear bolts hand tight and ensure that gear is squarely seated on case. Always use new bolts of proper type when installing ring gear. Do not reuse old bolts.
13. Alternately torque ring gear bolts to 48 ft. lbs. on Chevette and 1000 models or 80---90 ft. lbs. on other models.
14. Press side bearings onto case. If old bearings are reused, ensure that bearings are installed in original position.
