Need Serious advice on rear axle.
I had the rear axle open last week changing the gear oil.
The axle tag says 4 10 88
my door says R7!
My truck is susposed to have ls but it appears it doesnt.
I dont know much about axle inyards but it appeared to my noob axle
eyes that its an open diff.
So, WTF do I do my truck has 70000 miles on it.. and I got ripped off an ls
Edit: I'm 99% sure my orginal window sticker said L/S on it too.. let me go find it.
