04.5 Duramax LLY
 

I bought my 04 Duramax LLY about 4 months ago it now has 82,000 miles on it I am also running an 8" lift with 37" tires. Is there anything I should be looking at that may need to be looked at or replaced soon. Any thoughts would be great as this is my first diesel

Thanks for the info! Thankfully I do have the LLY in mine and have had absolutely no injector problems (knock on wood) Is there anything i can do to help make sure they last longer?

well its the injector harness that gets messed up #5 and 7.

u can check the wheel bearings and see if they are still in good contion.
