Offroading probably did it. But I would say if you dont have any noise coming from back there, leave it alone. The risk is that if it further deteriorates, you risk getting metal from the spider gears into the big ring gear, and you risk chewing that up. Thats a much more expensive fix.

I was saying you should ditch all those gears inside the carrier, and get a locker. $300 or so for the unit

 

what do you mean locker?

 

Unless you do A LOT of offroading and are willing to deal with the increased tire wear, noise, and other aspects of a true locker, I would not recommend installing one.

About the spider gears, I am not sure how much they cost online... You should be able to find them though.

As far as a cause... I have seen this type of thing happen in one wheel peel events when the spinning tire gets a bite of good traction.

 

ok im a occasional offroader well ill look into the gears but probably wont do anything about it until i start hearing noises or sense any problems its just something i happened to notice when i was doing the fluid change thanks

 

Just to forewarn you, if you wait to hear noises, you will likely be looking at a complete rebuild on the rear end ($$$). To replace those obviously worn gears now (possibly even with used, good looking ones) will save you a ton of money.

I implore you to go price a rear end rebuild kit with new ring and pinion. Then also read up on what has to be done to setup a rear end. A quick hint, unless you have dial indicators, a set of mics/calipers, and a good understanding of how everything needs to be setup, a shop is your best bet.

The gears, especially used, will be a lot easier and cheaper in the long run.

 

I will deffinitly start pricing the gears or i just might bring it to a shop. My truck has never been to a shop when i owned it lol, i either do all the work or my dad that owned a auto repair shop in New york for 25 years before i moved to north carolina 2 years ago does the other hard stuff. But right now im in a fight with him so hes not going to be of much help. Thanks again

 

I had the same problem with my spider gears in my rear end. On my 99 blazer. It was cheeper to get a used rear end then it was to replace the spider gears. Then if you dont know how to dial them in and have to have a shop do it your looking at BIG money. It took my 2hrs to replace my readend. I paid 75 buck for the used rearend. If you do the swap you MUST make sure you have the same gearing in the rear as you do up front or youll really have problems when you kick it into 4wheel drive.

 

hmm interesting

I do have the GU6 in my glove box meaning i got the 3.42 gear ratio so

 

As I have already stated, you DO NOT need to setup the whole rear end again to swap out the spider gears. The work required is detailed above.

 

okk ill look into the gears again
