lmdew Posted September 11, 2012 Share Posted September 11, 2012 (edited) There is a painted code on the top of the rear diff. Anyone have the chart for the rear diff codes? Thanks, Larry Found this out there on the web: This information is from the 2008 Factory Service Manual and im not sure if it applies to any other model years. The two letter code is supposed to be on the rear differential in white paint. Rear Differential Code---Reduction gear ratio---LSD CD --- 4.444 --- Viscous CF --- 4.444 --- Viscous EW --- 3.900 --- Viscous HY --- 3.545 --- Torsen JE --- 4.111 --- Viscous T1 --- 3.900 --- None T2 --- 4.111 --- None TP --- 4.444 --- None XJ --- 4.111 --- None XU --- 3.272 --- Viscous XZ --- 3.083 --- Viscous Can anyone confirm the years the codes would apply to?

1 Lucky Texan Posted September 11, 2012 Share Posted September 11, 2012 when you say on top, would I need a mirror to see these? how big is the lettering? Quote Link to comment Share on other sites More sharing options...
lmdew Posted September 11, 2012 Author Share Posted September 11, 2012 Yes, they are on the top. Letters are an 1' or so high. They are under the support so you'd have to drop the diff. Quote Link to comment Share on other sites More sharing options...
