    02. 2500Hd

    I’m thinking of buying a Chevy 2002 2500Hd I do not know about diesels at all What should I look for and question should I ask. They replaced injectors not to long ago. It is in my price range which is key. Thanks

    How many miles are on it? The LB7 01-04 had issues with injectors cracking and I believe were difficult to get to... in 05 they addressed this with the LLY motor... I had an 05 and never had any “major” issues in 130k miles... Diesels can be expensive to fix... I’d do some research on the LB7 so you know what you’re getting into.

    The LB7 can be a great truck but as stated above factor in replacement of injectors and maybe even injector cups.

    Last time I checked it was about 10-12 hours shop time for just the injector R&R. That doesn't include draining the coolant or replacing any injector cups.

    The injectors can be anywhere from $1300-$4500 a set depending on the quality.

    They have come along way since the LB7. If it was me I would look for a LBZ motor. The LBZ was first introduced in 2006 as a replacement for the LLY engine. The LBZ offered significantly more power but was only available until the middle of 2007 when it was replaced by the LMM. The LB7/LLY were 5 speeds and the LBZ and newer are 6 speeds. LB7 had injectors issues, LLY had overheating issues, and the LBZ was just a great truck.

About us
“wayoflife” is a moniker that I’ve been using for 20 years now and I chose it because I think it does a great job of explaining, in simple terms, the passion I have for Jeeps and the Jeep way of life. This is a lifestyle that transcends age, gender and race as the only thing you need to be a part of it is a love for the outdoors, a desire to explore, a yearning to take on a challenge and a will to conquer it. Over the years, Cindy and I have attempted to capture the essence of this lifestyle through photographs and videos and share it with others around the world. And, this is how WAYALIFE was born.
