I couldn't find the codes you listed above on my door, but I did see a G144 on the door sticker. Any more input or info on the door sticker code??


I should have said the door jam, not the door. The G144(G-14-4) is the correct code. Your code says that you have an 8" ring gear w/4.87 gears and 4 pinion 3rd member. For reference my '91 22re code was G292m for an 8" rring gear with 4.87 gears and a 2 pinion 3rd member. Your Runner came with the 31" tire factory option. Unfortunately if you decide to run bigger tires and want to regear, you have to get a 3rd member from a 5-spd, or one from an auto that didn't come w/4.87's. Unlike the standard oem diffs, the 4.87 3rds housing cannot be regeared. However since you can sell the 3rds to people running 33's and a 5-spd you wont be out any money, could probably trade them your 3rds+cash for theirs.
