Loooong day of Jeep work. Got the new front axle seals installed and found out that whoever put the air locker in decided it was a good idea to make "o-rings" out of a 1/4" bead of silicone sealer to take up the space between the carrier and housing instead of using actual carrier shims. There's about an 1/8" gap on the right side after removing the silicone...
Next: removed the gas tank to inspect and clean the inside, outside and underside. New fuel pump assembly on order.
Removed the rear coil spring spacers and installed new bump stops. Not only were the spacers installed erroneously (no other suspension parts upgraded to accommodate the lift), they were installed incorrectly.
Mo' betta
Readjusted new track bar afterwards.
Last but not least, opened the rear diff to look for the air leak. THANKFULLY, this one turned out to be an easy fix with no further fubar'd parts discovered. Just a leak at the plastic air line. Removed, cleaned, reinstalled.
Also cleaned all the old lube and crud out of the axle. Would have put it back together but couldn't find my RTV. So... done for the night.
Oh, and also discovered a missing bolt on the driver's seat.
