Just got the bill, they replaced both birfs (I provided 1, bearings (4) all seals, gaskets and miscellanous items), installed that PITA A/C line - total cost $1100.00. Good work for good money. I have no complaints, they were good guys and will send them more work.

I still can't get the center dif to lock, they thought it was the viscous coupler / transfer case that was screwed up (yesterday's news) and then today they thought it was something with the Engine ECU. I am scratching my head on that one. Not sure about that diagnosis, I am going to get into my service manual and see what it says, I thought for sure that it would be the Locker ECU that would be the issue - this is starting to drive me nuts, if I can't get the center diff to lock, then the other axles will not lock either - and that makes me angry.

Good to hear the feedback on the IPOR work. I was considering contacting them for some things as well.

Bad to hear about your center diff lock woes. I'm guessing you already posted up the behavior somewhere else to see if anyone could help out? If so, I'd like to read it if you can point me in the right direction.

are you SURE your center isn't locking? My switch was bad and intermittent. I had to buy a new one (they are the same as the axle diff switches BTW, so you *could* try to swap one to test)

IOW: the center was locking but the switch wasn't showing it.... therefore I couldn't lock the front or rear

No problems since

At OBX right now on the 4x4 beaches and I still can't get the dif to lock. I did find out someone mod the 7th pin.

The switches were replaced with a new ones from Cdan (transfer case & center diff). The locker ECU came from a junk yard and I am wondering if that part could be the source of all my pain.

Take that locker computer and throw it in the trash/ on ebay. use this write up to have everything work. http://www.norcalttora.com/~dick/Writeup Stuff/toyota_elock_control.pdf

I imagine you will use the same circuit for both lockers and the center diff.

Another thing. Us Taco guys have somthing called the "gray wire mod" basicly you ground out a wire so you can use the locker at anytime, any speed, any drive 2H for example. Somthing like that may apply for you.

again, are you SURE your center isn't actually locked and its just the LIGHT that isn't coming on? (no offense, but you didn't answer and it would point to a totally different problem than your thinking if so)

get in the sand, put it in low range, drive a bit to make sure it's got time for the center to lock, VISUALLY confirm that when gunning the gas only one tire (probably front) spins for a bit until the other axle starts to spin (center viscous coupler)

If the center IS locking, one front and one rear wheel should spin at the same time (no lag)

check it out and report back

watch out for the horses!!

Side question...Did you have to buy a permit to get on the beaches this year? Heading to Oakracoke Island soon...

If you are coming to the outerbanks you don't need a permit, just some good common sense, like don't drive a mini van on the beach, or maybe your mom's volvo, yes, I have seen it all this week and let me tell you Darwin has some good data.

As for the center diff issue, I have been driving around with the center diff switch on, no light - I just discovered that someone else did the mod on the 7th pin on this truck and it wasn't me. I was the one that installed the center diff switch! The lights do work, I ground out the connector and both, the center diff light and abs light came on. I have been driving the beach like a madman and working the transfer case when the situation dictates and right now no lights. IPOR told me it wasn't locking and I can't get it to lock, this may actually have to go to the stealership eventually.

Someone mentioned that it might be the engine ecu and then I am thinking, could it be the locker ECU located on the passenger side foot panel, it is the only part that was not purchased new.

if you're sure your center is not locking then your on the right track for your problem

I just want to make sure you understand what I'm saying in that my center WAS locking but the sensor in the transfercase was intermittent. Therefore, even though my center WAS locked, my light wouldn't come on and the ECU thought it was NOT locked. I had to replace the sensor switch on the front of the transfer case. (IIRC it's the same sensor switch as on your axle diff)

My point is that you cant just assume the center isn't locking correctly by looking at the light on the dash. It was lying to me and might be to you. If so it's an easy fix (new switch in X-fer case)

Have fun in OBX and yes.... there are some stupid people on the beach. I saved a minivan last year and a subaru this year. (awesome sight dragging a whole vehicle around like a rag doll.... a real crowd pleaser as everyone stops to watch )
