If you need to do adjustments to your Goes 520 then it is always recommended to have access to a Workshop Manual to keep just for a guide if you want to know methods to take off a particular part including Drive Shaft and match it again in the right way.
Goes 520 Workshop Manuals offers clear specified diagnostic info on your car so if something is wrong it helps you find out what the problem is and the way to fix it. You can then evaluate if you can do this by yourself or if ever the job is just too big you could make a reservation for your 520 right into a nearby mechanic.
