The speed sensors are wired directly to the electronic module. The process of removing and installing the sensors is relatively simple, since after disconnecting the cable, all that remains is to remove them. The sensor ends must be protected from contamination if they are to be installed again.
The toothed rims of the front wheels are mounted on the drive shafts. The gear rim can only be replaced after the drive shaft has been removed. If the gear rim of the rear wheels is damaged, it is necessary to completely replace the rear wheel hub. To replace the front wheel gear rim, remove the old rim from the shaft and fit the new one onto the shaft.
