An outboard propeller shaft bearing is a device that provides rotation and movement in the space of parts. It fixes the axis, supports the shaft and perceives radial loads. But, like other parts, the outboard bearing of the driveshaft (Mercedes or VAZ - no difference) will sooner or later require replacement. In this article we will consider the stages of this process on the example of domestic VAZ models 05-07.
Tool preparation
In order to replace the bearing of an outboard propeller shaft, you will need 2 open-end wrenches of 12 and 13 millimeters, a hammer, a steel extension, and also pliers with which you will remove the retaining rings. Also, do not forget about the special bearing puller, without which this process is simply impossible.
How to remove the driveshaft outboard bearing?
VAZ “five”, “six” and “seven” have a similar chassis design, so the instructions for installing and replacing this part are suitable for all of the above models. So, let's get to work. First of all, we put the car on the inspection hole and remove the driveshaft, as well as dismantle the cross (using a 27 key, unscrew the bolt). It is worth remembering that the nut should not be completely removed - you need to leave a little space on the thread for further pressing the plug.
And now we need a puller. In general, it can be of different designs - when choosing, be sure to ask the seller about which model of car it is intended for. Using this tool, we press in the fork of the propeller shaft. It is possible that this part may get stuck and not stick out. For this we use a hammer. There is no need to knock heavily, otherwise both the puller and the fork will deteriorate. Next, we press out the desired part and remove the base plate. Then the bearing itself should be pressed off the shaft. To do this, find 2 corners (50 by 50) and using them, leaning on the cardan, press out the worn out spare part. If necessary, you can take a metal tip and through it gently strike with a hammer. Everything, the bearing of the outboard propeller shaft is removed.
But our work does not end there. After we have removed the bearing of the outboard propeller shaft, the retaining ring and the anti-reflection washers must be removed. Then you can proceed with the installation of a new spare part. Installation is carried out in a similar way, but here it is worth noting one nuance - a new part should be lubricated before work. As a rule, manufacturers lubricate it in advance, but this is not enough. In order to ensure normal rotation of the driveshaft to the machine, it is necessary to gently pry off the bearing cover (wall) with an awl and process it. Everything, now the new part is ready for installation. By the way, if you notice that this spare part is scrolling with hooks, it is better to change it to another one, since such a part is either defective or forged.
Following these instructions, you can easily replace an obsolete spare part with a new one, ensuring your car a long and trouble-free operation.
