  • Q:

    I have a 2000 Silverado 1500 Z71 with the 373 gears. 231,000 miles
    I bought this kit, GM8.6BIL and installed the side gears. I then tried to install the top/bottom gears and they won't go. I tried slipping the carrier pinion shaft into place and it won't slip past the axle ends. I compared my old gears with the new ones and the side gears are nearly identical except that there is a slight difference in the depth of the collar spline that inserts into the carrier. The shims included were used. What should I do to get this to fit correctly? Take out the new shims? Is it necessary to have shims? This kit I ordered from the local CarQuest and the package was an opened product. Is it possible I have the wrong shims? Do I need to wedge something in-between the axle ends to compress it some so the parts I have will fit?
