Service 4WD alert
My mechanic said I needed to change the transfer case motor...it's about $165.00 on ROCKAUTO, or you can spend an additional $100 at O'Reillys....depends on how soon you want/need 4WD.
I have not tried changing the transfer case oil...if it needs changing EVERY 50k miles that might be a problem... since my 03 Avalanche has 315k miles on it and I really don't know if that fluid has ever been changed...mine is currentlying out at the moment and I was thinking of ordering ANOTHER transfer case motor..( this will make #3 that I have put on ), don't know if water is my problem but my 02 Tahoe doesn't have this problem and it has 245k on it...
