What did you do to your NNBS GMT900 Tahoe/Yukon Today?

[Rocket Man]

Got the Tahoe into the tire shop for alignment after the leveling kit. I noticed yesterday that the drivers side front brake line was seeping up at the hard line compression fitting where it goes from hardline to softline on the frame so they'll look at that too.

I think its going to be time for a dual battery conversion and a pair of optima yellowtops sooner than I was expecting. I killed the battery yesterday and put it on the charger for several hours, and it started right up to pull it into the garage. This morning it almost didn't start.

Do you have a lot of load that requires dual batteries? Maybe yours is just bad. FYI Optima batteries have fallen out of favor in the last few years, I think the company was sold and iirc their batteries aren’t all that good anymore. Do some searching and reading up before deciding on what to do. I know from what I was reading Ill never buy one of them.

Not currently (haha get it?) but I do want to set up a car laptop, I have a dashcam that I leave running 24/7, maybe one of those hidden winch things that sits behind the stock bumper in the future- I've just always hated dead batteries. My S10 had an intermittent parasitic draw for 3 years or so that I didn't solve until the last year that I had it. I'm not sure what batteries I'll get. I put a red top in the S10 and that solved my dead battery issues before I solved the draw issue. Will see.

With the tahoe I can only get about 2 to 3 hours of key on radio/fan off time. On the S10 with red top I could get about 4 hours of radio on time, and that was with two 12s bumping.

Optima batteries were purchased by interstate and moved operations down to Mexico. I use blue top optimas daily on my boats (coast guard) and they suck! Some batteries are getting only a year before they stop holding a consistent charge, and we had a couple batteries pop within 6 months of purchase. Not sure if red or yellow tops are the same story, but definitley not the same as they were 10 years ago.

Sucks they went that way. Do you have suggestions for a replacement to the Optima batteries? I always liked them, and used them. Have the red top in the Yukon now, but when it needs to be replaced, I want to get a good quality replacement.

I have one of those but I need a bigger compressor to run it. That’s next on my list. Tired of running out of air.

Yes, they are some air pigs. But they make the coolest sound! lol

 

[iamdub]

My, what a scary sounding name for a tool LOL

LOL (Literally)

I can't believe I never read or thought of it that way before.

I do not. I'm not sure what the latest go-to batteries are. I don't have a need for anything other than just a decent normal battery. I will in the future though, when the one in my bagged Silverado goes bad. At that point I will be looking for something really good since its important to be able to run the compressors.

I was going ro suggest using the air body saw instead of the die grinder with cut-off wheel on the plastic. The die grinder spins too fast and melts/rolls the plastic and makes more of a mess on the cut edge to have to clean up.

If you balance the speed with how fast you advance the blade just right, the molten part can usually be peeled right off once it cools. Although, they do sling tiny blobs of hot liquid plastic everywhere that stick to skin and burn like tiny sprinkles of flaming hot magma.

I would like to do this. Grab the grounding by the horns, too! these trucks and newer vehicles are finicky about voltage.

I have had good luck with odyssey 34/78 I use the DT (dual terminal), they won't fit the correct direction on the passenger side battery compartment but the cables will reach, they might make a model that has the terminals reversed for the passenger side, drivers side works just like they always have, If I was going to go with a standard battery instead of AGM, I would use interstate
