You're in the same mindset I'm in. My axles have been sitting beside my Jeep for about 2 years and I'm finally getting back to it. Since I was already having them out and any of these would be a short delay in the re-install, I'm doing:
- Tie Rod Flip (I'm doing a BBK too so I sent back the original knuckle to Blaine and he sent me back a flip-drill knuckle)
- Rear parking brake flip
- Iron Rock Lower Ctrl Arm Mounts (my fronts have the mini-skids so they were ok but I'll move the skids over; rears are bent)
- Replacing all the brake lines with SS (rear axle SS from the kit were wrong so I have new Crown lines) - My rear line was rusted where the soft line meets the frame & had to be cut
- Weld on the Currie rear TB mount (while out)
- Replacing Dana 44 axles seals & bearings while they're out (actually replacing them on spare shafts and keeping the originals as spares - cheaper for now than buying chromoly - I already had spare Dana 44 shafts on-hand)
- Currie Steering w/ BMB Tie Rod - in for a penny... I've bent my steering too many times already and even if I'm flipping, I'm going all in.
I'm not sleeving anything (recommendations on these axles are against it being useful).
I'm not bracketing the knuckles (Ditto reason)
I'm not trussing anything - I'm not at that point in my Jeep beating yet (My driving style is to grind down the skids vs jump the axle in the air...)
