If you have to conduct maintenance on your own Daelim History then it is usually a good idea to have access to a Workshop Manual to use as a guide just in case you need to know simple methods to strip off a particular part including Drive Shaft and fit it again successfully.
Daelim History Workshop Manuals will give precise diagnostic details with regards to your car or truck so if something is not working it will help you discover what the problem is and the best way to make it better. You will be able to assess if you can do this yourself or if ever the job is too big you can book your History in with a nearby mechanic.
