I'm stumped

I've got isues. Keep having problems with my traction light flashing under accelleration after 2nd-3rd gear that causes my gas pedal control to cut out and the damn thing will not throw any codes. I have my snap on scanner running and all its showing me is a 3mph split on the rear left sensor. Found gear oil on the sensor. Bad seal. Put a new sensor in just to see if it was the problem before ripping the axle out to replace the seal and the issue still exists. What am I missing?

 

Fix the problems you see. The axle seal isn't the end of the world, I'd say 2-3 hours if you haven't done it before. When you have everything apart, clean it super well. If you got a non-OE speed sensor, be sure to save the original, as you may end up needing to put it back.

 

I pulled the seal, cleaned everything out and re-installed the sensor. No issues yet. Just can't figure why the seal let go. It wasn't even a year old. Done when the axle bearings were swapped

 

Sometimes parts are bad out of the box or get damaged/dirty during installation.
