I jjust found out my new truck has limited slip rear diff. I am curious to hear what you guys think of the stock unit in these trucks.

 

General consensus seems to be-They suck.

 

That's exactly what I hoped not to hear but I kinda figured I would hear that. What is the problems they have so I know what to look for?

 

There are some clips for the clutches that like to break, and fall out. Then the rest of the diff eats itself. They are also a tad on the weak side.... sure wouldn't hurt you any to pull the cover, have a look, clean it out, and put in some clean fluid, WITH the additive.

 

Does anyone know of hand what option code that was on a build sheet?

 

I will check the sticker for you and let you know what the code is on my truck. @ hey you thanks for the information will have to have a look. I'm sure the oil needs changed anyhow.

 

Jlow sorry its taken me a while to get back been sick and screwed up my back. I can't read the code on mine but I found the sheet of paper with all the extras the truck was built with under the hood. It does state limited slip differential on the paper.

 

From my sheet-
I've owned my truck a month. I'm terrified to pop the cover and look at it. I have a feeling I'll crap myself.

 

I re-geared at 150k miles.. my 3.92:1 w/LSD was still snugly clipped, and working properly.. I stuffed the 4.56:1's in there, and retained the LSD.. So far, no problems..

I don't know what the deal is with those clips.. I'm thinking they don't hold well to abuse.. abuse being the operative word.. I've never abused my rig.. A really hard launch, or turning 90* and standing on it, is what I term abuse.. You can accelerate as fast as you want, so long as you do it from a rolling start- and you can launch out of a turn the same, so long as you steadily increase speed as opposed to standing on it.. yeah, it isn't near as much fun- but, it's about the only reason I can give as to why my LSD clips have never failed.. (now that I've said it out loud, I fully expect to have issues)..

 

I know next to nothing about diffs. Where are these clips and what should I look for when I do pop the cover off?
