SEPT 10TH 2019
Just thinking to myself and out loud I guess.
If I need more height in the bags, and don't want lift why not just trim the lower bag mount down an inch? I'm assuming the bags will be Ok higher.
Probably not all that hard to unbolt them, cut them down and reweld. They are the ones with the angled plate.
I STILL THINK THIS IS THE BEST SOLUTION. RUN A SHORTER BRACKET AND 2" TALLER BAG
And.... My oil leak is getting worse! Grrrr no idea where it's coming from now. Looks like rear main ish as the most of it is around the back of the oil pan and the bellhousing.
Upper pan doesn't look like it's leaking.
Underside is well oiled now...
Begin ramble...
Spring rates. you need a minimum to hold the weight up. No two ways around that. BUT with the air bags, you have to add pressure to get the height. A spring can be made taller at the same spring rate correct? Where in the air bag the spring rate is increased with air pressure. However in theory the spring rate is as low as it can be to hold the weight at X height?
Zip ties on the shock shafts show I am not using the front suspension. Nearly NOT AT ALL. When I got to the start of gravel, I hopped out, three fingers of movement on the shaft, ~2.5" uptravel.... Thats not much (and not bottoming out on the bags)
Here is after a pretty decently rough section. A bit more movement, but still not much...
I did try inflating the bags to 9" tall. No difference, a bit worse even perhaps (more spring rate...). And they sit funky on the bases like that, not happy looking.
Frustrated.
Should I go back to coils? Just try to find taller softer ones?! Anyone have an idea of spring rate needed? 6200lbs on the front axle.
Went and played on the rocks.
Shoved my phone in and took a bunch of pictures.... This one caught my eye once it was on the computer. Looks like possibly the dipstick (or whatever that tube is..)? There is no "gunk" stuck there, high flow spot?
Ok some progress!
Took the truck to the store, hit a couple big hills and got oil to 200 degrees.
Half a roll of paper towels and a can of brake clean later we have this. Clean ish.
Idled in the driveway for 10 mins, now look at the bolt holding the dipstick! Should I replace the whole thing or just try to do the Oring?
our fucking shitting me. That's all that's left of the Oring, if there was ever one....
Gonna put this one down as a win (so far!) a couple hundred miles and a couple passes and it's leak free! Going hose down the Underside with degreaser, I really hope this was the oil leak all along!
Bag data!!!
A little hard to read, But shows the curves and spring rates. spring rates @ 80psi 535, @100psi 658 (at 9")
Played with air pressures this weekend.
Tires at 58.
Air bags at 70 which is just under 8" tall, its a bit better, BUT it does bottom out at this pressure.
At 60 its not any different feeling than 70 really. at 80 its harsher.
The Kelderman guys think I am feeling the rear end.... Maybe my expectations are just too much for this heavy of a truck?
