1985 Toyota 4runner, 250,000 miles, 22RE, Auto Trans, 4.35 geared

Ok, so I put in a Detroit EZ Locker into my 4runner. Everything went in pretty smooth. When I went for a test drive, the locker was working until I crawled over a huge boulder. The 4runner actually cleared the builder flawlessly...then I heard a loud bang and the 4runner shuddered back and forth going any further. I took the 4runner out of 4x4 with the hubs still locked. The banging stopped but the steering was way off...like I had no power steering. I had to really turn the wheel in order to make simple turns.


I unlocked the hubs and the steering is fine. If I shift into 4x4 (hi or lo) without the hubs locked...no banging and no problems steering. Only when the hubs are locked does it act really weird. Any thoughts, suggestions? I used only Toyota seals and torqued everything to spec when rebuilding. I am thinking my locker is screwed up.


Thanks for ANY suggestions. This board is awesome!

Locker is in the front and i am running 32 inch tires.

a locked front end tends to want to pull the way it wants to go. I run an Aussie up front and at the end of a day of wheeling my arms are tired.
I use a twin stick so that I can pop in and out of 4WD when I am binding up.

Did you do the set up yourself? If so did you do it correctly? Remember to put the thrush washers back in? I got lucky on my 1st Diff set up, I got the carrier bearings mixed up. Than I ended up following a write up on Zuk's site: http://gearinstalls.com/
to undo my mistakes...

but from the shuttering to described it sounds like you might have sheared a tooth on the ring gear...

Stupid question, but do i need to use the old thrust washers on the EZ locker if the locker was installed in the front diff? Would the absence of thrust washers cause the problems I am experiencing?


Thanks,

that is also a possibility...one reason I have a twin stick and Dirty 30's

Jared: did you do any hard turns in 4WD with the front wheels bound up that might lead you to do this to a birf?


If the instructions for the Detroit are like the Aussie than yes.

From what I understand a Detroit EZ locker is a typical lunchbox locker (http://www.offroaders.com/tech/detroit-ez-locker.htm).
Sometimes people forget to take the Thrust washers off the diff gears and put them on the locker..



can't say for sure this is your issue but offering a possibility

u dont need to be turning in a bind to blow them up, ive gernaded a few on soft dirt hills, and blew up one backing out of my driveway. after replacing 9 birfs in 3 months, i got longs with hub gears, now the outter hub gear breaks.

JaredL

Thanks all for the responses. We'll find out when I tear it all apart next week. You are all referring to "longs". What are those? Longer axles? Where do I find them?


Thanks,

Update your thread when you find what you blew up.

Chromoly 30 spline birfields are Dirty 30s and Longfields.

Both work well.

This guy should get you pointed in the right direction if you are in need of birfields or longfields
