Rear End HELP, no I don't need depends ...... Yet!
 

I'm tuned and deleted, went to a big diesel event (Rudy's Truck Jam) for diesel pulls and drags up near Greensboro, NC. Ran 4 passes at the drag strip and now the ELOC DIFFERENTIAL won't unlock. I've cycled 5-6 times, bumped it forward backward and no go. All I can think of is to jack it up and try to rock it and bump it, and maybe a few taps with a ball peen hammer. :-huh:-huh

I've heard these E loc rear ends can barely handle stock power and really be reliable, so tuning is an even bigger issue. That's word of mouth by a few people there but don't know. I've been tuned for over two years, I've done truck pulls at least 15 times and no issues.
Maybe it wasn't my day. :'(:'(
Has anyone had experience or know about this happening?

For what it's worth:
R/T .721 sec
60' time 1.883 sec
330' time 5.686 sec
1/8 mile time 8.965 sec
1/8 mile speed 75.14 mph

Truck weight 8,450 lbs!

If my memory serves me right the computer should automatically disengage the E-Locker above a certain MPH, I want to say 30?? Also have you tried driving to the left and right? I haven't ripped mine apart to really look at it, so I can't be the best of help.
