**UPDATE** - Shifter Leak & Clutch Pedal Bushings
Going to start putting more mods AND repairs in there. As these things get older, they seem to get more needy. But that's ok because 3rd Gen's rule.
I had a leak that was dripping onto my belly pan. I could see what looked like gear oil running down the side of the trans between the T-Case and the Trans. At first I though it was the seal between the two units but I called my good friend (Ex - Toyota Master Tech) and he told me to check the metal gasket at the shifter. Knowing I did Marlin shifter bushings about 8 months ago and it wasn't leaking then, I was honestly in doubt, but thought before I dig too deep and make a rash decision, I should check. Low and behold, I pulled the shifter trim and shifter boot off and this is what I found. (I re-used the metal gasket when I did the shifter bushings)
Harder to see than I remember - but rearward of the shifter you can see the dark oil stain from the leak.

Pulled the shifter and cleaned off the base in prep for some RTV.

RTV'd this face as well as both faces of the black metal "plate" pictured above.

Then I re-assembled - wish I had some brake cleaner to clean the oil residue but I was out!

Been about 7 weeks now and the oil leak has stopped. Good news!
Next up was the shifter bushings in my clutch pedal. As you can hear in my Magnaflow exhaust video, I had a prominent squeak on clutch depress. I had read all the horror stories of a squeaky clutch pedal being left too long causing the actually clutch pedal retain to wear and eventually require you to buy a new pedal with all the bushings. It appears Toyota never really did "fix" this issue and a lot of people have attempted fixes on the forums - using a brake spring instead, different bushing material (rubber types, brass, and even 3D print). However, I just think this is going to become a frequent maintenance item for me. Once it squeaks - remove the pedal assembly, pay the ~$100 for new parts, and put it back together. I bought everything including a new OEM spring, even though mine wasn't showing any wear.
I used this thread for reference (some Part #'s in here too):
5-speed clutch pedal sticks on floor in morning (three days in a row)
First off, I highly recommend removing the whole pedal assembly. I tried to do this job while it was in the truck and ended up tweaking my neck pretty bad. hahah (I guess I'm getting old?). Should have just unbolted it in the first place and I would have been done in 1/4 the time.
Checking the old parts as they come out - Pedal assembly pivot bushings actually in decent shape.

Here you can see the black clutch spring bushing was cracked and starting to deteriorate. Spring retainer bushings exploded when I tried to remove them (white bushings). Can also see that my clutch spring wasn't worn in the metal like some are when they do this job.

Here you can see the groove where the black clutch spring bushing sits. on the pedal assembly. Luckily for me, the metal shape has not been eroded at all and therefore the new bushing will fit in there as it should, upon replacement. A keen eye can also see the Toyota parts sticker on the side of the assembly. This makes me think that the previous owner had it done at the dealer early in the trucks life under warranty when Toyota "updated" the design. I have every receipt for this truck since it was brand new, and there is no invoice for this item, so that's why I'm thinking it was a dealer/warranty fix. My truck has ~305,000kms (~190k miles) of mainly highway driving its whole life. Surprised it's held up so long.

I installed all the new parts on my work bench. Before I did that though, I greased everything heavily in Moly grease. I know it works good for these plastic-type bushings, so I thought why not? Put it back in the truck and it's been absolutely silent in operation for the last few weeks. So happy to have that annoying squeak gone!
