Shiny new made in USA Denso pre cat O2 sensor. I used @RobRed super handy table Oxygen Sensor (O2) Part Numbers and Replacement and Densoaftermarket.com to identify the proper sensor #s. My truck is to from April 2005 on the chart. Got all 4 denso sensors and Lisle O2 wrench (needed for the front) from RockAuto.com for just under 210 shipped with fedex ground.

After +120k miles and 15 years and a recent P0051 code after our turkey day trip to Mammoth and Mono Lake, I also replaced the other 3 o2 sensors as PM. These were factory og ones (Toyota with Denso markings). I had run to Autozone to get a M18 x 1.5 tap to chase one side. For the front set I went from the wheel well and undid the aprons. I turned the wheel to lock and wormed my way in. I didn’t remove my wheels or skid. But it made for some cirque soleil level contorting, gonna be hella sore tomorrow.

One of those connector release tools was super handy, I normally use a set of adjustable pliers like the Knipex cobra to disconnect but due to the awkward angle, couldn’t get to them. If you have a menards near by their masterforce tool is made in usa.

The post cat O2 sensors were the flange style, 1 nut on each side I had to use my Knipex Cobra plier to remove. Rust and heat had fubared these nuts. Penetrating oil helped a lot. I replaced with stainless steel 8 x 1.25 mm nut and locking washer from Home Depot.

Error code resolved after short non freeway test drive. P0051 tripped my check engine light, and VSC/Trac lights. Verified code went away with ScanGauge. I need to clean throttle body/maf and reset ecu to see if I gain back some mpgs and pep. Still on all og coils with fresh boots but installed new denso spark plugs at 90k.

Will add part #s tomorrow and pictures of the post cat nuts.

Good approach going through the aprons. I wish I would have got the Denso sensor. I spent as much for one Toyota as you likely did for all four.
 
Swapped Bilstein Shocks for the garbage strut master shocks. Pretty substantial difference in road manners. Thanks for the help @Jboyd !!

I got them through Rock Auto, for just under 210 with the Lisle O2 wrench and fedex ground shipping. I think 06-07 sensors may be pricier? I would also get the Lisle O2 sensor chase tap if I were to do it again.
 
Pretty much the most uncool thing you can do with your 100 series. This is my wife’s kid/grocery carrier. Throwing 300, 305, 306 codes. Time is tight with EOY work stuff so I had it towed to my Sherpa @Jboyd for a thorough examination and PM plan. Can’t have the wife and kids’ chariot leaving them stranded after all... Appreciate the assist from @WhiskeyBullets for the gophering!

Today's work was getting the alternator pulled, I hoped. I DID finally manage to get everything off except the connector on the rear. That thing is on there but GOOD, and I'm a little at a loss as to how to get it off. I can squeeze it, I can wiggle it, but it just doesn't seem to want to come free. My gorilla hands aren't helping. Since I'm not trying to keep this alternator, I squirted some PB Blaster around in there to maybe loosen up whatever's seized up. Trying to be as delicate as possible since I don't want to slip and rip those three tiny 245k-old wires off, as that's gonna make more a pain in the ass.

Pointers from the hive mind? Special pliers? Swear at it in Japanese?

Have determined that most/ at least part of what killed the old one was leaky PS lines dripping gunk and goo in and probably gumming up the voltage reg, so I've got a couple of those on the way in as well. If I'm gonna be covered with grease and goo up to the elbow, I'm gonna try hard to fix what's causing that while I'm in it.

Decided while I had the skidplate off that I'd hit it with the ol' flat black by way of cleanup. Everything else under there is dry and tight- I remain amazed at how well these old things hold up.
Just did this a few weeks ago. The connector on mine crumbled (98 LX, 126k) so I bought a new OEM one online for about $10 IIRC. This connector is for 98-02 I believe; the newer models have a different connector. It’s basically just matching the wires into the new connector. However, plugging the new connector into the alternator was a little tough for some reason. I also replaced both PS hoses and the reservoir. No problems since

Replaced the leaky old china radiator with what turned out to be a leaky new China radiator! :grinpimp:

Ordered a Mishimoto replacement radiator a few weeks back and just found the time to install it this morning. After starting it up I noticed a small but constant drip and realized this tiny fracture slipped by my inspection. :redface:

Reached out to mishimoto and hopefully they will resolve this quickly and painlessly as one of the main reasons I purchased from them was their warranty system they seem to be fairly proud of. Unfortunately their customer service call center is closed on the weekends, so I hope the email I sent reaches them before Monday.

Anybody have a quick fix I can cover this crack with until a new one comes? Old radiator was busted as well, so not much good putting it back in:cheers:

Disappointing; was hoping this would be a good alternative to OEM, as the Denso units appear to be hit or miss as well. Hope Mishimoto makes it right.

my guess is that it’s less of a manufacturing defect and more of a shipping “Defect”.

this is what the box looked like when it arrived at my doorstep. Subpar packaging and lack of padding/protection will 99% of the time result in sh**** product by the time it gets to the consumer... other than that it looks like a really quality product and was excited to install it.
 
dropped it off at superdudes house to have the ahc gutted.

Loving mine. I spent the weekend pulling off remnants of AHC and dressing up the frame for some sliders next weekend.

Picture with some Trail Tailor extended links. Need to install rear upper and lower control arms next.

I've had this happen before. With radiators, ask before you order if they repackage the radiator before shipping. If they don't, ask them to do it or don't order from them.
 
I think I've been swearing I'd create a heat shield for the catalytic converter for over a year now. Time to finally stop whining about dropping the skids and just do it. Got everything greased up and the oil changed out in the transfer case while it was easy and accessible.

Built the shield out of some scrap stainless laying around and some fancy space tape because why not.

After what feels like a decade of being trapped at home, and one holiday where I cosplayed Pac Man in a kitchen ...the LX needs more lift or I need Jenny Craig.
 
Gearing up to hit 60k miles in my 06LC! Changed the plugs, heater Tees, and checked the coolant. I did the AHC fluid and adjusted the pressures a couple weeks go. 275/70/18s on order to go on some tundra 18” TRD wheels. Ordered a victory4x4 roof rack! Oil change happening this week as well as lubing the drive shafts.

Replaced my swaybar bushings, but managed to sheer off the rounded front D bracket bolt. Flank bite wrenches are a great investment, BTW.

I’m delaying drilling out the bolt for another day since I really don’t want to play the torsion bar adjustment game right now.

Turns out a plug was loose and destroyed itself and the coil boot. Had to tap the head and put an insert in. Fingers crossed
