I'm about to service my diffs. Based on some forum discussions a while back, I was trying to figure out if I had a LSD rear end or not. I could not find any evidence that I did. I posted a picture of the glove box sticker. I remember several forum members thinking it would be strange for my particular truck to not have LSD. Anyway, I finally got around to getting a build sheet for my truck and this is pasted directly from it: "DRBS Corporate 9.25 LD Rear Axle"

I don't see LSD but I do see LD. In my glove box it just says "Corporate 9" on the bottom line and maybe it just ran out of room or ink or both. So based on this, does LD mean I have it or I don't? I just need to know if I need the additive for my rear end or not.

 

Been googling this a bit. Best i can tell, code drb with the ld is standard axle, light duty. For lsd, it would have dra with anti-spin designation. Can anyone concur or deny?

 

DRBS Corporate 9.25 LD Rear Axle is the LSD

 

Damn, it shouldn't be this confusing or misleading. I guess I'll just make sure the fluid I get has the additive or I'll buy some additive and put it in there regardless.

 

"LD" is Light Duty.

 

might be light duty but i know "DRBS - Corporate 9.25 LD Rear Axle" is on my build sheet and i know i had a stock LSD
