Transfer case help
 

Hey guys I have a quick question. Ive been having problems with my transfer case and ive beem thinking about buying a new one or rebuilding this one. I know that there are different types like such as 241d, 241hd etc but mine is different. Take a look. Never heard of a 241 LDD. HELP?
