Repair and replacement of the
rear axle gearbox
(GAZelle 33021) is a very serious and responsible business. As you know, this spare part has a very complex structure, so you need to make any repairs with it only at a special service station using special tools and equipment. However, if you are an experienced driver and know the design of the GAZelle like the back of your hand, self-repair will not be ineffective. In this case, do not renounce the manual for the car and do everything at your discretion. In this article we will analyze all the stages of removal and installation of the gearbox, and also find out its exact price in the Russian market.
Disassembly instructions
To begin with, the GAZelle rear axle gearbox needs to be removed from the car and only then proceed to disassemble it, having previously clamped it in a vice. So, the first thing to do is to unscrew the screws that hold the locking plates. Next, you need to mark the bearing cover so that when reinstalling, do not mix up all the details. After that, proceed to dismantle the outer bearing race. After removing them, it is worthwhile to carefully examine their condition and replace if necessary.
Also, do not forget that the backlash of the axle shafts should not exceed a mark of half a millimeter. If this figure is too high, then you can not do without replacing the differential box. Next, remove the planetary gear, knock out the axis of the satellites, and then pull it out. The rear axle reducer of the GAZelle must contain a shaft with an inner ring. The last part must be removed, and then with the help of a steel punch, pull out the bearing. Then change the adjusting sleeve and remove the adjusting ring.
After that, the rear axle reducer GAZelle can be considered disassembled. Now we turn to the most important thing - inspection of the condition of all parts. It should also be noted that all parts of the gearbox must be washed. If you find a crack or other deformation on any part, be sure to replace it. Otherwise, it will make itself felt after a couple of thousand kilometers when the car is on the road 100 miles from the nearest settlement. If the spare parts do not have any deformations, but there are gouges on their surface, then replacement is not necessary. For their well-coordinated work, it is enough to simply polish them with sandpaper. If the most important components are damaged, replacing the rear axle gear (GAZelle, in particular) is simply inevitable. So you save your time and extra effort.
