Yay. I wonder if the previous owner left it in AUTO most of the time.

I wish the front hubs had the ability to stay together without the axles installed. That would give me time once the snow goes away to leave the front diff & axles out while I tear it apart, and have a shop install the parts. (or a buddy with the presses/pullers).
4wd hubs don’t need the axles to stay together. That’s a crappy Jeep thing.

Mine has 210k in 2hi only.

That's good to know, and would certainly remove some difficulty in getting my front diff whine assessed and fixed over time, vs. having to take my truck off the road.

Old me would risk it without much thought, but I'm trying not to kill off the kids in the back seats if I can help it.

Thank you for this. It may well save my bacon down the road. I had to use that converter harness for my cam swapand it’s just a little short so it strains the sensor pigtail. As Monica also asked, please do post the details of the ICT part.

Oh good call - i will edit the original and post it here, part number is WAVVT40-10

This is the 10" adapter, so it directly replaces all the OEM harness on that part of the motor. Seems to be running just fine from driving it all weekend and into work this morning.

If you buy it on Amazon from ICT, you get free shipping, vs 11.99 shipping if you buy it on their website ( which is silly because ICT is like a 5-6 hour drive from where i live )

Yesterday, but I finally got around to changing out the bad DRL bulbs in the front with some LED's.

Doing the first bulb I had a total brain fart and went after the high beam, tried to pull the high beam out of the socket after removing from the headlight assy. :jester:
I'm just glad it wasn't the low beam since those were already replaced a few weeks ago! :emotions133:

I figure the high beams were the next to go out anyways, so I stuffed some SilverStar ultra's in there.
low beams are Sylvina's "whitest light."

I always love trying to get those headlights out of there, but body and the fenders sorta lock them in making changing the bulbs possible, but a serious pita. :violin2:

I haven't tried the brights out, but the drl's are bright and white as fk now! :waytogo:




Watch, now the turn signal bulbs will go out since I didn't change those.
:chair:

My 1926 is taller than my 1929.
By 1929 cars started getting a little lower than the really old, tall passenger compartments and overall profile.
My 1929 Pierce Arrow is very heavy, coming in about 5,000lbs on a 143" wheelbase so it will be on the ground while my 1926 Rickenbacker is taller but much lighter being a smaller car.
Man, I love them old classics. Would not mind having something like that from the 20s/30s

Anyone looking for a new radiator??? I hv the all in one, TOC & EOC Aluminum Mishimoto GMT--99 brand new, unopened in box, for $550 shipped. I hv external TOC & EOC, so it's a waste. I'm going with their radiator, minus the EOC. I also have silicone red hoses, I will toss in for $50.

well poo.....wasnt the harness causing the issue...CEL came back today. However the shop that did my DoD delete called me back and we chatted, he said throw a sensor in it to see what happens, sometimes they are start to go out or if it had a bad connection on it, it could have messed it up. I got a new one at lunch, might take off tomorrow morning to work on it since it sits in a very warm spot of the motor.

Twice this weekend, I took it an hour NE to the house my friend is building to help build a privacy fence. My Tahoe took his garage's virginity on Saturday and he drove his toy up on Sunday for sloppy seconds and double penetratíon.
