What was done to your rig this week?

Had to replace the auxiliary battery again, battery is 8 months old.
O'Reilly warrantied it and the guy told me that the previous company they had making the batteries for them was having quality issues, the one I just put in should be more reliable... I hope.

That old battery only had an 80% charge even though I attempted to charge it with an agm charger.

The battery tester tested it as Good but with only 80% charge, it's the only thing I can think of that would make it give the error code.
put the replacement in, started the jeep, no error messages.

I wish I had my multimeter with me, I'd like to know where the aux battery wires end. I took what I thought were the two grounds from the body after removing the main battery and they were still sparking each time they touched the body.

Anyone know if the aux battery charges while driving or does it only feed off the main battery?20250702_135523.jpg

I had to undo my "neat" accessory wiring, it was too neat and, in the way, 🙈

Technically it charges while driving but it all flows off of the main battery, not directly off the alternator

Thanks for the info, so maybe having ESS off all the time might also be causing the battery to die as it seems having it on creates the charging mode for the aux battery.

I'm leaving ESS off (tazer) but plan to check the battery with my tester in 3 months to see what the charge level is, then run it with ESS on and again check it to see if there is a change in charge level.

The old battery, even after attempting to charge it with an AGM charger read 80% charge level (CCA tested fine and overall, the tester indicated a good battery) but I still had the ESS warning icon, and I was beginning to get key not detected quite often.

Only difference with batteries, the new one had a little more CCA and the charge level was 100%

The inner hulk wants to sledgehammer the ESS system.
 
Any recommendations for aftermarket knuckles?

I figured I might as well go HD this time, I’ve looked at Reid, RockJock, and Synergy. I’m leaning toward the Reid racing parts but have no real reason to be biased
Yeah, the aluminum ones are bullshit, should never have been added to a rubicon. I have the Reids and they are awesome, despite the orange. However, any of the steels would be fine and significantly better than the oem.

I did the Synergy knuckles not too long ago.

Easy install, everything lined up perfectly and the steering is still a lot tighter than it was new.

If you live anywhere that you have corrosion, be prepared to replace other parts.

I installed Synergy for the similar reason, BJ not broken but I noticed wear signs on the OEM that I don't see in steel knuckles and the corrosion was bullshit.

I like the Synergy because they are fully coated them, time tell if the hubs corrode but the coating on the knuckles is supposed to prevent that.

I anti-seized the contact point between knuckle and hubs.

After seeing the corrosion on the aluminum knuckle and the rust on the OEM bearing I knew I would have to do something.
It was fun separating the two.

I was going to replace only the ball joints but after the amount of time spent trying to separate the driver side hub from the knuckle and the amount of corrosion on everything, I ordered knuckles and Spicer hubs (only units that had the same size lug bolts)

Glad I did because I couldn't separate the passenger side hub from the knuckle and removed it in one piece.

I added anti-seize on one side to compare between the anti-seized side and the Synergy coated side when that time comes again

I have a hydraulic pulley puller from way back when. Had to hillbilly engineer it as it is too big for this application. Eventually both hubs succumbed to the mighty force and popped out. Landed square on my foot both times, hub and puller. That was some fun.
 
I installed the r p m extreme temperature controller today. Pretty straightforward hardest part was getting the stupid plug case off. It started up, and no lights came on.So that's a plus😁 the hottest it got was 201, so we will see next week when the temperatures rise..

Well, this shit didn't last. Got the ESS warning icon going through Monticello on the way back to Texas.
I'll pull that fucking battery out again and see how much charge it has

Is that a fan controller?
 
Honest question: Why are folks obsessed with the temp range of these V6’s? None of the 4 Jeeps I have with this engine have ever overheated. I’ve driven Gruff out West several times through the mountains on I70 and never came close. If anything will do it it’s driving up the Ike. Other than me thinking he was gonna blow up due to the lack of O2 and redlining most of the way up zero issue.

Again, honest question not an attack. I’m genuinely curious
