I really dont want to drain it because its expensive as fuck. Draining it to fix an issue is fine but not checking for one. Its $19 a bottle and takes 2.5 bottles and a tube of friction modifier ---

Yeah, its synthetic and thats whats required. The front takes the cheap shit but for some reason the rear needs the expensive shit. I bought it at Advance when I got it changed by a friend. Really I dont have any desire to be fucking with gear oil and wouldnt know what I was looking at if I drained it anyway. Id be draining it, looking at it and then putting new fluid into something with bad parts anyway. I dont know how to replace bearings in a rearend and would rather have somebody else do it if thats the case. Id cause more trouble with it. ---

Id cause more trouble with it. Drain it into a clean container, run it thru a fine screen (or a paint filter, just might take a long time), and inspect for debris. Very simple concept. ---

Yeah and if theres something in there Id have to take it somewhere to get fixed anyway so theres not much of a point in doing that other than saying there was something in it. ---

Right, I see no advantage of troubleshooting a problem yourself (for free) before bringing it somewhere for repair. ---

What I mean is I really wouldnt be able to tell where the metal shavings are coming from and I wouldnt be able to repair it because I dont know what to do. I really wanted a general idea of what could be wrong and to see if anybody would be interested in fixing it. ---

Jellies didn’t ya just do a pinion seal ? I’m betting it wasn’t tightened and lock tightened . Cords have a bad issue with the lock nut loosenening up and doing that . Ya working Tommorow? I’ll come get your truck and see what it is man ---

K ill grab the truck , what I’m betting is the jam nut loosened up and the ring and pinion now has play causing a gear whine . Most of the time ya can retorque the not and lock it and your fine but sometimes it does wipe kit the bearings and ring and pinion . ---
