Hey guys i have a question about my rear diff. Its a 3.55 and the door jamb sticker says (axle 19) so i'm guessing its an open diff. Well i was messing around in the back yard a drove up on a dirt pile and the right rear wheel is off the ground and i start spinning then 5 seconds later i felt a thump then the driver side wheel is spinning so i'm just confused with what kinda diff i have.

 

You are correct 19 is 3.55 open. Did the drivers tire pull you off the pile?

 

Yes the driver side tire pulled me off

 

Maybe your spiders got hot and welded in place. No lube in the Axle? No LOL intended.

 

If I were you I'd pull the diff cover and check things out

 

I would check also

 

Well i pulled my diff cover and it was full of lube and also what i saw i think was a traction lok i bought this truck a year ago i guess the last owner could have down something to it

 

Look at the little metal tag on one of the capscrews. It will tell you what you have. Picture looked like the gear assembly with with cross pin and keeper missing. Is it broken out in there somewhere.
