- Changed the oil.
- Got another set of R-comps mounted and balanced. (Heading to VIR for 3 days this coming Thu/Fri/Sat, wasn't sure the tires on the TD wheels would do another 3 days, so I elected to play it safe and mount up some new NT01s. The Z214s only have 2 days on them, so they'll be used again next year.)

- Changed the diff fluid.
- Discovered the center CV on the driveshaft has spewed its grease. This is the used driveshaft that I installed earlier this year; my other driveshaft (with the voodoochikin poly center bearing) is in my garage.
- Discovered that my PMC seems to be leaking inside the car.

I'd say somewhere in the 1.5-2qt range. I used a hodge-podge of leftover fluid (Redline, Motul and Amsoil 75W-90), and was using the various bottles to refill the one bottle that my hand pump would actually fit into.

If this the first time you've replaced the fluid in your differential, make certain that you can get the fill plug off before you remove the drain plug. They can get really stuck--the last thing you need is a dry differential on your daily.

- Installed the winter wheel/tire setup. Supposed to be some lows in the 20s this week, so I figured it was time. I'm sure this means that there will be a late November / early December warm spell, with temps in the 60s. ![Tongue](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_tongue.gif)
- Replaced both front O2 sensors. I've been getting P0135 and P0053 (both indicating an issue with the driver side O2 heater circuit) for a couple/few weeks. Got the sensors (ACDelcos from Rock Auto) earlier in the week, but hadn't had a chance to crawl under the car to take care of it. Both sensors came out of the bungs easily, which was a pleasant surprise, but reaching the wiring harness connectors was a bitch, particularly on the passenger side.
- Part of the harness difficulty was that I chose to remove an O2 sensor harness extension that was left over from when I had Kooks on the car. The driver side one was already gone, but the passenger side one was still there. Unnecessary, but it did make it easier to plug the front O2 sensor in. At some point it got too close to the exhaust, so it was a bit melty:

So I kind of screwed myself by removing that, as the factory harness plug is damn hard to get to. I ended up plugging the harness in blind - I could see the engine harness connector, but once I stuck my hand up in there to try to guide the sensor connector to the engine harness connector, I couldn't see ****!

Finally got around to fixing my differential issues. It appears that I had both a leaky vent and a leaking pinion. And a non-existent diff front bushing.
Installed the new pinion seal, the pinion nut is 36mm btw, and it was a pain to torque down--210 ft lbs, had to go in steps, and had to press ebrake as far as would go. Then pulled the axles, and pulled the diff out. Covered in yummy oily dirt.
Replaced the diff bushing with a black CS unit -- getting the old one out was a pain, hacksaw and lots of persuasion. New one went in with a 35mm socket and some persuasion from a 3 lb sledge (way easier than getting old one out).
Pressure washed diff, and then swapped in new axle seals.
See pics:

The diff bushing orientation is critical to successful part life. The line on the face of the bushing should be oriented up and down, not side-to-side if I recall correctly. I believe the instructions are on the rental tool sheets, but not when you buy the part alone.

Code appears to be fixed. Didn't come on during 4 drive cycles today, whereas for the past 10 days or so it's come on every time shortly after starting the car. (I could clear the codes, and they would stay off for the rest of that drive, but the next time I started the car they'd come back.)
As for the headers, I removed them to make clearance for hose routing for my oil cooler setup. Hindsight being 20/20, I probably would've gone with some other long tubes in place of the Kooks rather than the JBA shorties I've got now, but such is life. Months and months after I had changed things up I saw a pic that showed the SW headers (at least, I think it was SW) route quite a bit differently than the Kooks headers in the vicinity of the ports above the oil filter (where my take-off adapter is located), so they might have given me the room I needed. Ah well.

Sidenote, I was cleaning out the garage recently and found an unopened box from Amsoil with two quarts of 75/90 gear oil and the slip lock additive. I guess I ordered 4 qts when I changed the fluid originally? I'm due for another change, so happy day!

Pinion nut took a 1/2" breaker bar and 1/2 my floor jack handle (3 ft, 1.5 diam) with e-brake on, then had to brace against underside of car while I wrenched on it so I could get enough leverage. Was actually harder to put on than take off (but not by much).
