Front diff locked up while driving in 4hi

Make sure to be present when they open it up. Not that they are bad guys, but most people are a little more honest when someone is watching. With all the expenses you face, I think they owe you this much.

 

Yeah thats the plan. Also just curious to see what happened

 

Let us know what you find out.

 

ouch

 

Apparently the pinion is stuck to the diff housing and they need to call someone in to torch it so I went home. Picking up the truck tomorrow.

 

Ouch is right. That's pretty much what I was expecting to see. I wonder how the pinion is stuck.

I re-geared my 1992 pickup myself with Yukon gears, ARB locker in back, Spartan locker up front and luckily haven't had any trouble yet. But seeing this from a shop is probably why lots of individuals shy away from doing it themselves. If a shop can screw it up, a shade tree mechanic can really screw it up.

 

Catastrophic

 

Did it spin a pinion bearing? If so, you’ll probably need a new clamshell.

 

I don't know anything about anything here, but that doesn't sound good, let alone the hit it took locking up. Maybe a tech can chime in, if this should be replaced and sent to the butcher.

 

They said loss of oil flow due to bad design by toyota. Whatever that means. Sounds like im on my own regarding the transfer case too

 

That's not a thing. Did you see any oil come out when they drained it? They butchered it and made something up.

 

Nope I didnt get to see them drain the oil. Gonna go get my truck, replace the transfer case at home, then go from there.

 

Loss of oil flow....pure BS . The diffs are a bathtub design. The oil sits in there like a half full tub, and the gears bath themselves as they rotate through the oil.

 

Boy would they be surprised to see that transfer case Monday morning laying behind their front window.

 

I dont know too much about pinion depth maybe someone here can chime in. This is a pic from when they did the front locker in September. Is anything wrong with the pattern (you can barely see it sorry)

 

The front diff is a high pinion design. I think there is a port that oil gets slung into to oil the pinion bearings. I’ve heard when you go to 5.29’s the bigger ring gear can block that port a bit. But maybe someone with more understanding can shed more detail on this.

 

I stand corrected

 

Literally every Toyota 4x4 truck would break if that’s the case

 

Well this (before) picture does appear to have all the teeth on the ring gear, (and based on the after picture,) that isn't compatible with their installation methods apparently... Maybe this time they will grind all those pesky teeth off first.

All joking aside, sorry to hear this OP. If its any consolation, at least all these parts are (relatively) accessible and can be reasonably fixed after these liars are done. Better this than forgetting to refill the crankcase, etc.

 

Haha. Thankfully I have all the stuff to replace the transfer case sitting in my garage ready to go. Ill be wheeling this weekend
