Asked by Sep 11, 2015 at 08:15 PM about the 2001 Chevrolet Blazer 4 Door LS 4WD

Question type: Maintenance & Repair

Was told by Chase dealership that the Transfer case was cracked and leaking but had a reliable person check and said it was fine and not leaking or cracked. The Blazer was stuck in 4 wheel drive for 1 month and ran at 60+ mph .

So your saying the it is or was in 4WD and you were driving 60plus mph? That is why your using so much fuel.


It was in 4 WD. But for the last two weeks its been back in 2WD its been using a lot of fuel. Only used it for 2 weeks before we figured out it was stuck and it had been sitting for a month until we got it back to 2 WD.

How's the rest of the drivetrain? Any wear or binding? You sure your in 2WD now?


Had it checked again and it has been in 2WD for the last two weeks. But I did just replace the driver side wheel bearing and hub today. There was some play in my upper ball joint and bushings, lower control arms, idler and pitman arms had some play.
