Hello Guys need some help. I have a 2007 gmc sierra classic 1500. It has a gu5 rear end that took a crap on me. My question is, is there any other differentials i can swap without having to modify anything. 

 

Im looking to get a replacment at a wrecking yard but cant find a gu5. 

 

I dont care about hauling or my truck being faster or fuel effeciency. I just need the thing rolling again. 

 

Please any help would be appreciated.

On Car-part.com, I see one as low as $200. You would have to input your specs though, as there are about 40 different vehicle options to choose from for that year/make/model.

Thanks for the help. Im just looking to know if I strictly have to go with a gu5 rear end or if I can install something else. I want something that will drop right in.

  If you are desperate to get the vehicle moving, you could possibly remove the rear drive shaft in put it in 4x4, but I would not recommend it - unless there is volcano or a zombie apocalypse. As for what you can swap out without mods, I have no idea. You might be able to fix your rear end though. What exactly is wrong with it?

i just changed the rear diff in a 2005 sierra 1500 with a diff out of a 1999 chev 1500 both trucks had the same rpo codes, just had to switch backing plates because the 99 had rear disk and the 2005 had drum brakes

You can put any rear in there that fits. 

You have 3.23 gears, even a gu6 with 3.42s will work or even a gt4 with 3.73 will work. 

I’d go with what’s cheaper and could work. Or open up yourself and see what’s wrong with it. 

You will just have to get your truck programmed with the correct gear ratio for the ecu.

I have a 2006 chevy silverado 1500 crew cab with  brake shoes on the rear. I believe it's a gu5. My question is: Can I swap it with a 2007 gu6 with disc brake? I can find a gu6 with disc brakes for $220.00 The brake conversion kit is $480.00 and up. I'm not liking those kits. Any help is appreciated. Thank you.

      2026 DENALI 6.2L

      By pyoung62 · Posted

      I agree with Tim.  As tech heavy as engines are these days, no way I’d be an early buyer of the new 6.6.  Of course, I bought my ‘26 Denali w/the 6.2 after dumping my Tundra with it’s defective 3.5 liter imploding engine disaster, so I’m a little gun-shy.  That said, my 6.2 has been rock solid.  I don’t drive it like I do my BMW Z4 M40i, but I don’t baby it either.  I got a V8 for a reason.  But I’m averaging 18 around town and 22 highway.  I have seen 24 highway as well when I wasn’t loaded up heavy.  Considering my Tundra with the twin turbo V6 only got 14.5 in town and 17 on the road, I’ll take the 6.2 all day, every day.  If I were you, I’d grab a ‘26 while you can.  Inventories are probably gonna start dropping and I’ll bet the deals will start looking sweeter as well.

      Can you add a 360° Cameras hard button to a 2021 Sierra?

      By ShowMeShooter1332 · Posted

      I am curious if anyone has figured out a way to add an hard button AUX or 360 Camera switch to the center row of switches. I have a 2021 AT4, and want to split the hill decent button and add a 360 camera button so that you don't have to go into the center display and locate the camera functionality, etc...   My father's 2024 Yukon XL AT4 and it has a hard button, see below. I found this thread on the Yukons, but it seems like there may not be a part number for the 2021 sierras. https://www.gm-trucks.com/forums/topic/255339-adding-hard-button-for-camera-on-2021/ Anyone else figured this out. Seems like it would need to be a custom switch!   I am getting ready to install the auto stop/start eliminator, so would be nice to knock them out at once.     Upvote1Downvote0Go to comments

      Oil Consumption

      By Chuck FB · Posted

      Through the years it hasn't been my typical method as I tried to drop oil on an engine that was hot from having been worked, however that was not always practical and had to fire up a unit and let it warm up reasonably well and drop the oil when I had the time to do it but am referring to not only vehicles but a variety of farm equipment and highway tractors etc. However on a vehicle where one is crawling under it and the exhaust is nearby to ones body and if wanting to pull the plug without danger of being hit with boiling hot oil or attempting to remove a HOT oil filter, its sure safer and easier to not have everything smoking hot and can remove the filter right away when under the vehicle and let it all drain. Of course its not the end of the world if a bit of oil stays in the engine that might have eventually found its way out, I like to get out as much as possible but any oil changes that take place in shops would rarely be sitting around for very long at all before the plug is thrown back in and filter slapped on and oil poured in and sent out the door quick like. There would be very little time spent ( assuming they even did it ) in starting the engine with oil to fill the filter, then waiting to verify the level on the stick. A good reason to check ones oil level shortly after a shop changed the oil on a vehicle just to make sure its correct and to look under for any oil around the drain plug or filter.
