The shakedown run brought a few issues to light.
I didn't seal the shifter plate on the magnum box... oops (fixed)
The front bump stops are too long in their current position. (shortened all four by making spacers)
The rear tires rub the springs about an inch before full articulation. (plan on 14b srw hubs and adjust bumps)
The valve seals were definitely bad enough to require changing. (replaced)
Lastly... I need bigger tires.
Had to put some headlights on so I could drive it to work a few times to see how it did. Pulled the pods off the wrecked truck I picked up.
A few days after the shakedown, one of the tires decided to fall apart.
To make tire changes a little faster I cut down all but four of the studs.
Then tried running over a grand marquis... the suburban is a bit too wide. lol
Part of getting all this done quickly was to be ready for the Chile Challenge. The week before the event, it started having fueling issues. Couldn't get above 60 and the more I drove, the worse it got. Changed the filter and cleaned the injectors and got a re-tuned...better, but still not good enough to drive 3 hours on the highway.
Made it almost all the way through the first trail with no issues. Bent the tie rod, then blew a tire (just so happened to be the spare), and went back to running so bad I couldn't go over 20mph.
This picture accurately shows how much I need bigger tires.
On the bright side... all the Yukon parts held up to both of us quite well.
