    So I swapped in an SR5 cluster from a v6 4runner into my 22re standard cab. I heeded the warnings of not hooking up the oil pressure sender, but I've been dragging my feet on getting an SR5 sender.

    Drove it like that for a few months, then my wife talks me into using a free oil change coupon we had from meineke. It was good that I took it in there because I was unaware that my diff was leaking again, even though it's been less than a year since I had the seal changed and u joint replaced, so now I'm thinking, what's up, is my pinion bent? They also told me I was about a quart low in the motor, but I'm worried about my diff, right?

    Anyway, that was Saturday and I had driven it home and to work and then today on my lunch break I notice my oil pressure gauge looks a little different than before, instead of rock bottom it's sitting over top of the L. Then it dawns in me that they probably noticed my dangly wire and decided to "do me a favor" and hook my oil pressure sender back up. I drove the rest of the way home in horror realizing that they fried my gauge. Checked it and sure enough it's hooked up.

    So here's the funny part, though. It now rolls all the way up and then slowly moved back down every time I start it. (Which has been twice since I noticed) I thought it did that when it gets fried and then doesn't move anymore after that? Am I mistaken that the symptoms of a fried gauge are actually all the way up and all the way down Everytime instead of just the first time?
    Is it really fried, or is mine somehow magically spared despite my stupidity in not replacing the sender sooner?

    So I did pull a sending unit from the local yard. I figured $4 was a better plan than $50 or whatever a new one costs. I'm in the same boat, though. Haven't installed it yet. I've been on the lookout for one for a while and finally found it the day after this happened, so go figure.
    I read the fsm and it recommends loctite when you install it, so I need to pick some up before I actually put it in.
    Once I get it installed I'll report back on whether I need a new gauge, too.

    Now if I can just get the diff to stop leaking and the clunk in the steering or suspension taken care of and I'll have a nice little truck.

    Sometimes the seal lip will wear a groove into whatever is passing through it, in your case the drive flange. When this happens a new seal wont fix it anymore unfortunately.

    Well that was my problem a year ago, replaced the u joint, seal and flange. Then shortly after that it started rattling again. I had someone else check it and they said it was fine and they thought the rattling was the drive shaft. So I drove it like that for a while, but now it's leaking again.
    There was some uneven wear on the flange, so I'm wondering if the pinion is bent or something. I don't want to replace it all again and have it get all wonky again in only a couple months.

    Did the 4runner have the dummy oil sensor or more advance sensor. If it had the advance one then yes it should work, buy i believe all the 4runners came with the more advance oil gauge.

    Yeah, I pulled my sensor from a V6 4runner, I don't remember what year, though.
    If you search for it on the O'Reilly website, it will tell you which other Toyotas it fits. The early nineties Camry is on there and I think a 2nd gen Supra.
    It's best to pull the sensor and the connector. I do know that the sensors changed at some point. The earlier ones had a little button that the single wire connector slides onto. The later ones have an actual plug that I think has more than one wire.
    I have read some posts where people were able to use the same connector that was already on their truck and just slide it sideways onto the button, so that's what I looked for. But, that was not the case for me. Mine did not have a slot on the side of the connector to slide it onto the button, plus there was a rubber boot that covers the sensor anyway that necessitated just clipping the old one off and splicing on the 4runner connector because the hole in the boot was only big enough for the wire.

    It's on the driver's side near the bottom front of the engine. I think the oil filter is nearby on that side, too.
