Reading my Diff tag

Handegard · #1 (**permalink**) 10-26-2009, 03:23 AM

First off, the tag says-

V127A (top line)
L55 10 2 5F1 (bottom)

IIRC, the L55 means the diff came with a Limited Slip and 3.55 gears, right?

Is there any other pertinent info in there?

If my rear end is a LSD, it's clutches must be long gone. I can light off one tire fires

all day long on accident, it feels like a open diff.

there should be a 3 in ft of the L55 but its usually partially covered by the bolt that holds the tag on the rear

I re-sealed the differential yesterday, and I tried to clean the tag off as best I could, but that was all I could see. I think the 3 was probably crushed by the bolt or worn off long ago, I wasn't the first person to have that cover off

I need to add some LSD additive I suppose. I was told based on my door tag that it was a 3.55 LSD, but it's always behaved like a open diff, untill my fluid change. It isn't chattering, never has, but it used to do one-tire burnouts with ease, and it hasn't since I did all the fluids over the weekend. I did do a nice 2 tire burnout today though

I get the BG stuff, it's around $10/tube at NAPA.
