Gearing swap qustions ....

Hello everyone ...
I need help from you pro's on gearing swap..
here it is short and sweet.. I want to regear because I run Dick Cepeks crushers and there 32.5" tall and I dog offroad and gas mileage got murdered so I want to get torque back..Its a 2010 tacoma with a 5 sp manual trans with 4:10s motor has no mods and is a 4 banger..
so 4:56's right (nittros gears said I need a front carrier because there gear is thick) or 4:88 no new carrier req'd..
this is a everyday driver.
1: do I need a new carrier in front!
2: 4:56 vs 4:88
3: add arb air locker(heard seals go and need changing every 2 years)
4: machined thrust washers or crush washers?
5: brands and links(yukon and just differanials I know about and they are very pricy JT QOUTE is $2550.00 in parts with arb and upgraded air comp!).
thank you very much ...
Happy New Year!!

You can get thin 4.56 that work with your existing carrier, but it's pretty common to go 4.88 for the 4 banger 5 speed.

2800rpm at 70mph. It's a pretty quiet motor, so tire noise is still the loudest thing in the cab at 70mph.

And you haven't even thrown speedo correction into your price mix yet .
