For those of you not taking this too seriously, you should get it fixed asap. I had my dif seal "repaired" by my local GMC dealership in Oct. I began leaking again in Jan and making noises, I had an appt to get it fixed again on Friday and a few days before on Jan 22 my wheels locked during a downhill turn at 45 and I ate a grove of trees. The car kept me safe aside from some whiplash, but the wreck caused over 9700 worth of damage to my poor baby, she is STILL in the shop and probably will be till next month.....I got the recall paper in the mail a week and a half AFTER my wreck.....timing is everything.
So you really should get it fixed, there's no way to tell if the damage is bad enough to cause your drive to lock until it actually does and apparently not all dealerships take this seriously.....
