Ok the clock is ticking t-minus 3.5 hours until I leave and travel to the happy thanksgiving place. I noticed some oil this morning not again I thought and it was from the front diff. New to me I thought though I just had an alignment done ugggg damn tire kingdom anyway the driver side portion of the 4wd isn't disengaging. I pulled the hub and still nothing, the pass side is fine and spins free the drivers side won't come undone and is causing the shaft to spin and so on and so forth @ 80mph. I have 2 option
1. you guys help me figure out what the hell is going on which I like
2. pull the shaft and say it until I come home, though I will still have to figure out why it is doing this.

Bump

The driver side shaft doesn't disengage from the diff, only the passenger side does. If the shaft is spinning while driving then the problem must be in the manual hub.

 

Hmm maybe but with manual hubs in the free position neither cv should spin, remember I dont have ADD any more .

Aaron

 

Right I forgot about no ADD, then sorry I'm all out of ideas

 

Might have something to do with it? This is one if the pins from the Aussie locker.


Aaron

 

Well, I was going to say it sounds like something from the diff, and not a problem with the hub. Ugh. That is a little scary.

 

My truck and I have a love hate relationship. Right now she is very hated. Though I hope there is nothing terribly wrong, I'm thinking about pulling the darn thing apart when I get the the office this afternoon.

I had to search HI and low 9 different Toyota dealers, to find these damn axle seals. They were $12 ea. so I bought 2 just in case I buggered one up. The removal went somewhat smooth, the old seal removal wasn't a problem, the new install was weird. It just wouldn't seat, so I read and read and decided to make a tool out of some 1" pipe and a wood block. This aided in the proper seating of the new seal. I won't know until tomorrow whether or not this have solved the oil leak issue. Now as for the cv that has become bonded to the hub bearing well that is still a separate issue. Dang!

After a couple months of driving I finally had some time to drop the truck off for service. Turns out the reason my manual hubs wouldn't disengage was do to the fact there were needle bearings in the splines of the cv. Huh needle bearing huh? where the hell did they come from I asked politely. Apparently in the actual hub assembly itself has a race inside with a set of needle bearings and they somehow fell out and got lodge in the splines causing some light scoring on the cv shaft but nothing terrible. SO in all I needed new wheel bearing, hub assembly, and seal. $315


Aaron

 

Well ! Now the passenger side is ing up on me. I had similar symptoms and had to pull the pass cv to replace the inner boot anyway then saw it. There was some heat scoring on the cv shaft itself where the needle bearing contact it. I lubed the hell out of it and used a screw driver to move the race around a bit and the wheel seemed to move more freely but still snagged occasionally. These aren't cheap as the whole hub has to be replaced in order to replace the bearing race. Anyone else running into this with either a taco hub swap or just your taco that uses the aisin system?
