**The 8.5 axle was used on vehicles up to 1999. The 8.625 was used on vehicles 1999 and up. Since 1999 was the transition year, some vehicles received the 8.5 while others received the 8.6. The easiest way to tell the difference is by looking at the brakes. All 8.6 axles have disc brakes and 8.5 have drums. Both axles use the same ring and pinion gears. The main difference between the 8.5 and the 8.6 is with the carrier bearings**

This unit has the bigger bearings that uses race number LM603012. The previous carriers before 1999 had smaller bearings that used race number LM501314. Some 1999 (still older body style) suburbans and ZR2 S10 still use the smaller bearing units.  This unit can be used in the older housings if the bearings are replaced with LM102949 and race number LM10291

Pinion bearing may be a different size. They used 2 different Sizes but the gears are the same for both
