I found the original sticker in the prev owners folder... It has 3.92 gearing, LSD , 4 wheel ABS Brakes and tow package

Truck bran new $31,000

Truck with 24k miles sold to me for $10,000 ...I am still in shock over this great deal!

 

hmm i got my 03 1500 qb sb slt fully loaded 5.7 4x4 w 70,000miles for 8,000.

 

Keep an eye on that stock LSD, you are approaching the mileage where people start to report the implosion followed by the inevitable complete loss of the rear end. I suggest frequent lube changes in that rear and with carefull inspection of not only the fluid but also a close look at the magnet for C-Clip fragments. I don't think ANYONE with the stock LSD has escaped this issue, if so, I'm sure the percentage is very small.

 

damn ...what kinda place can I take it for that kinda treatment?

 

First of all, I'd do a search on here for "C-Clip" issues. It's probably the most talked about subject on any Dodge Truck Forum. I'm on another forum with a section on it, where the people who have had the issue actually join the "C-Clip Club"where the thread is literally dozen of pages long.

You can check/change the rear differential fluid yourself and inspect for pieces of metal that is the tell tale sign of a failed C-Clip. It's not really any harder than changing your oil.
You could also do what many, including myself, have done and have the LSD unit taken out and replaced with a much better aftermarket one such as an Auburn or Detroit unit before the stock one explodes and takes out your gears and virtually your whole rear end, making your $10,000 great deal truck a $13000 O.K. deal truck...

Here's just one of the many threads on it on this forum:

damn seems like a pretty serious thing..[] Thanks for the advice hammer... but If I tell my wife I wanna put in a aftermarket lsd shes gunna flip out thinking I just want a new mod...Dammit this sucks

 

does the 7 year 70k mile plan cover this if it breaks...cus I am getting that roled over

 

Yea, I think so, to me, the rear differential would be considered a part of the powertrain. Maybe some guys who have had the issue will chime in here.
I really didn't mean to **** in you corn flakes here, but with that low mileage, it's very possible that the original unit is still in there, and I just wanted you to be aware and look for the signs of a failed c-clip before you ended up having to replace the whole rear end...

 

how much does a new LSD run? and then instalation to, my tax return is prety decent this year. ha

 

they vary in price.. i think the auborn locker is real popular and i think its available at 4 wheel parts.com so check it out.. labor also varies on where you get it done and whos doing it..
