Sorry for the confusion and pre-diagnosis of the rear end failure.

In my first rear I have only Toyota fluid in it. I changed it every 50k. I only switched to royal purple when it began to fail to try and fix the issue.

In my new rear I am using mobil 1 synthetic 75w-90. I had heard good things about it. The new rear is still in good shape and does get abused time to time.

I have added a pic of the ujoint cap from the rear most ujoint. I crawled under the truck and could not move the driveshaft at all so I assumed it was not a ujoint. I couldnt tell the ujoint was bad until I removed the driveshaft. My friend who has been a pro mechanic for 45 years checked it and didnt find any play in the driveshaft either.

Also, I do grease the ujoint every oil change. Each time they are nearly empty. Everyone should check theirs! I replaced the old ujoints with napa heavy duty ujoints.

Thanks for the help!

whew!!! thats one f**ked ujoint.i haven't seen anything that on a pick-up,seen it plenty of times when i was working on heavy duty trucks and the guy would drive in saying he some sort of clunking sound when he started driving,lol.i'm actually surprised they didn't fail sooner with the mileage you have and the fun you've had with the tundra.

Yeah it was pretty messed up. But I have had plenty of fun with my truck.

The weird thing is, the noise started on a friday. I towed a car out of state on Saturday, the noise got horrible on Monday, and I changed it thursday. It didnt give much warning. I had one go bad on our ram 1500 and drove it for probably 6 months with it squeaking before we replaced it.

The metal housing unit on the right has a gouge in it (the first picture posted), how did it get there? Did you hit a rock?

I saw that too. I honestly have no idea.

My thought is the cause may have lead to the u-joint failing.

That is very true, I never thought of that

yes,the wear on the cap on the right side of the pic is from where it was rubbing the joint itself without any lube or needle bearings.i've seen worse,as in a truck only coming in with half a cap or none at all,but that is bad.
