I have a 14 bolt rear end in my 2000 crewcab short bed. I have heard the term partial and full floater thrown around when talking about these rears also is there two different sizes available?. So what does this all mean

 

Also as i just got this truck and have never had a 2500 model, when I go to give it gas it feels like the rear end is locking into gear (as if it goes from free spool to locked in) as the truck starts moving. Is this a normal thing, could it be a neeed some new U-joints (I grabbed the driveshaft and it feels solid)?

 

thanks again for your knowledge...

Wingnut, I went thru the 54 options and figured out the following

 

GT4 - 373:1 ratio

G80 - Locking rear axle

 

So what does this tell me. (I thought there would be a code stating its a 14 bolt rear end versus a 10 bolt?

 

These codes one thru me for a loop

code X-88 - Chevrolet Conversion? could that be because of the

crewcab shortbed (its a rare option only in 99 and 00)

YD3 - Front Axle for scheduling GVW plate (this is a 2 wd)

 

I found a few other codes I could not translate

 

CMD - ?

R6P - ?

SLM - ?

VX5 - ?

ZQ3 - ?

1SB - ?

1SZ - ?

6XJ - ?

7XJ - ? (probably has something to do with the 6XJ code??

 

at the bottom of the list is BC/CC and U334D

      This is a really late reply but I just found this thread. They won't sell the hinges. I've gone 7 rounds with them. Their solution is to buy a new cover. I'm about to buy a new cover and it won't be a Bakflip. It also won't be from realtruck.com.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver.

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.
