#1 of 3 Transfer Case Randomly Disengages While in 2WD by sab03 Sep 02, 2009 (1:36 pm)
My 2006 Suburban transfer case will randomly disengage while in 2WD mode (happens 2-3x per week).   Instances of when this has occured are: - Driving on interstate at 75mph - Driving around town at various speeds - While in reverse it is initially engaged but will slip out - shifting from Drive to Reverse   What happens to vehicle when it occurs - Transfer case appears as if it's in neutral as vehicle will roll. - Light on transfer case control stays lit in 2WD mode - When shifting vehicle to park will make a grinding type noise. Will put vehicle back into gear and have same problem of no engagement (engine just revs). I have also tried turning vehicle on/off while in this condition and it still does not correct.   What I do to correct: - I push either the 2WD or Auto 4WD button and transfer case re-engages. I can then put the vehicle back into 2WD and it will drive fine until the next time it disengages. I may be noticing a decrease in mileage, but at this point can not say for sure that this is occuring.   Again, this issue only occurs while transfer case is in 2WD mode. I have taken the vehicle to the dealer and they replaced some gears?? in the transfer case, but I don't feel that they have a good grasp of the problem. Any help/guidance you could provide would be appreciated. Thanks Replies to this message: todd77 (Oct 05, 2009 5:41 pm)
#2 of 3 Front Diff by ngfinch Oct 04, 2009 (8:16 am)
I had the same problem in my Tahoe. It ended up costing me $1600.00. The fork that engages the front differential got mis-aligned some how and wasn't sliding in betwee the gears like it should and ended up grinding them down. So sometimes it would go in sometimes it wouldn't. The only time it worked for sure was when it was in 4x4. Good luck!

Replying to: sab03 (Sep 02, 2009 1:36 pm) I had the exact same thing happen to me yesterday on my '05 Chevy Tahoe while driving on the freeway at 70. The symptoms you describe are exactly what happened to me, only after the 3rd time I was unable to get the transfer case to re-engage. What did they end up finding wrong and what did it set you back? I'm expecting a diagnosis and estimate tomorrow morning. I have just under 50K miles on the car. How many miles did you have? Thanks, Todd
