Yea, the bad bearing apparently messed up the axle surface...I've never heard of these. After some research, looks like there was just a pretty deep groove in the axle shaft, expected with 285k I guess. These "repair bearings" Move the bearing so that it rides on a different portion of the axle that is unworn. I asked him to take pictures for me....I trust the shop, just want to see for myself what he's talking about.

How much would a replacement axle be??

 

Got the truck back and wow what a difference....haven't even really gotten on it for break in purposes but if you're considering gears, this is definitely one of the best mods I've done to my truck. It just seems to drive around so much easier, highly recommended.

 

Gears ARE one of the best mods you can do. Unfortunately, also one of the most expensive. Especially on 4x4's.

 

Keeping it under 2000 rpm for 500 miles felt like an eternity when I got mine replaced.

 

4.56s have very little contact surface just they are more prone to breaking teeth and making noise on the roadway, 4.10s are perfect for 33s to 35s as far as fuel economy and still having power

 

I finally hit my break in 500 miles and I fell in love w my truck all over again and REALLY notice all the mods I've done. 75mph and 2000 rpm on the button. Gonna change my oil and track bar On Wednesday, can't wait to see what my gas mileage is on my trip to Myrtle Beachthis weekend.

 

Did you change the gear oil after finishing the break in or is that what you mean by change the oil on Wednesday?

 

Catastrophic failure....I changed the gear oil, took a road trip to NC. Driving down the road about an hour out from my dads house 70-80 mph and I get vibration when i let off the gas. Didn't really pay it any attention I had been driving all night and was ready to be home. All of a sudden I lose my driveshaft and hear the worst sound I have ever heard from my truck. I get pulled over safely and check out what happened. I dont even know whereto begin on what may have happened. Driveshaft gone, where the transfer case attaches to the the transmission is completely sheared off, transfer case is laying on the crossmemeber with the rear of the transmission still attached to it, front driveshaft straps were broken. I just called my dad and he picked me up and I left it on the side of the road. Finally gonna go look today. I have no idea even where to begin, I just did my loan app on a 2014 1500 4X4, dont even want to deal w this thing anymore.

 

I wonder if they took your driveshaft off when they worked on your rear end (probably!). Then they didn't get it back on tight. It loosened, and took out your transfer case and rear of the trans. I would definitely be going back to them to have them cover the cost of repairs (but not have THEM do the repairs). There are no coincidences in life.


Worst case, get compensated from them and part out the truck. Sounds like you have a healthy engine that some of us would want.









Now for a little levity...



You probably already know all of this but I can't help but pointing out the obvious, since you were a marine. Now, if you were in the army, I wouldn't have to explain this at all.
