If you have to execute adjustments on your TGB 101R then it is usually a good idea to have access to a Workshop Manual for a guide just in case you want to know the right way to take out a particular part including Wheel Bearing and fit it again correctly.
TGB 101R Workshop Manuals can provide particular diagnostic details on your automobile so if something is broken it helps you find out what the issue is and methods to fix it. You can then evaluate if this can be achieved yourself or if the job is too big you can make a reservation for your 101R in with a nearby friendly mechanic.
