Spring time = mod time, am i forgetting anything

so my 01 has 153k miles on it and i want to do a once over when spring comes so that i am ready for wheelin all summer.

My thoughts are address the suspension:
5100s + OME 881
Allpro Expo leaf pack + Bilstien shocks 5125 most likely, greasable stock length shackles
At this time i may go ahead and replace upper and lower ball joints and install new control arm bushings (How hard is it to replace stock bushings)

Brakes:
Tundra brake swap
F/R SS lines
new drums and rear brake hardware

swap out all gear oils for synthetic (do the diffs or transfer case need any additives ?)

Engine:
Plugs, wires
MAF cleaning
fuel filter


is there anything major that should be addressed that i am forgetting?
I'm slowly purchasing the parts needed so that i dont take such a hit to the wallet all at once

previous owner said timing belt and waterpump were replaced around 130k miles

 

steering rack bushings? radiator flush? grease the drive shaft?

 

not major but I just realized we don't have lights under the hood so if you have any trouble at night it can be a PITA so while making a mod list you can add that to it.

plus if you are replacing the brake lines, take this time to consider switching over to a dual reservoir master cylinder for a safer brake system. that way if one wheel cylinder fails you wont loose "all" your brakes like what happens with our now.

 

is there a bolt in swap avalible for that? is it just divided Front and Rear?

Hood light is not a bad idea either, i have a ton of hood switches at work, would be a simpe install too, might have to use some LED flush mount strip lights for that to really make it visible at night.
