2nd Gen Tacoma axles swaps? Good, bad, etc?

I blew the rear end in a factory and trussed axle. I had 4.88 gears with 35" tires and the pinion gear for the rear end, in 2WD mode at the time, spit its teeth out. I want to go to 5.29 gears, so I was already thinking about axle swaps before this.

Replacement 4.88 gear costs with labor in the rear axle versus a new axle is close enough, that a new axle seems to be the obvious path forward. With the total cost of the regear with labor, I can probably sell the now empty (pulled the ring and pinion gear to make it mobile) rear axle and take that repair expense and buy a new Dana 60, or at least get close, making that a cost-effective option. Also, the factory E-diff engagement system is weak, with an unknown cost of repair or replacement.

With a 5.29 regear in the stock Toyota trussed front axle, which is ARB air locked, I think I might be good there. However, I don't want to break it with something like a Dana 60 in the rear working hard off-road, putting the front axle at risk of a failure.

So, what wisdom do the Tacoma owners here have for me? Dana 60 rear or something else? Is the 2nd Gen ARB-locked front good with a 5.29 gear swap, or should I also go Dana 60 there too? Or, should I look somewhere else for axles?

Initial, possible cost errors, are ~$5K for a factory-compatible (no suspension or drive shaft changes) Dana 60 from someplace like Michigan Gear, versus $3K~4K depending on who and where I have replacement 4.88's done in the rear and I would not get my 5.29's.

I don't really have the time for a UNICORN Ford Superduty axle conversion or similar option unless those are sitting somewhere I am unaware of.

My Tacoma is heavily modified, previously for MOAB challenges against Jeep Rubicon trails. Lifted, heavy armor, King Suspension, etc., so I also roll pretty heavy. On 35's today and thinking about 37" tires going forward. Planning a trip to the Alaskan oil fields next year and the tip of Chile the year after that.

Less than a week ago, a brand new Dana 60 arrived with 4.88 gears and an E-diff.

Got it installed and set up properly for my rig on Saturday. Tuesday, I drove from Texas to Florida to see Yota Mafia with it. I got a favorable review as well of the install from Yota Mafia out of Holt, FL as we inspected my rig for other mods.

This Dana 60 axle is something I wish I had done much earlier. It is an absolute beast for a Tacoma/FourRunner. Having manual control of the rear diff is awesome as well. In rural areas, I have used it locked and remain impressed.

Especially with 2nd Gen Tacoma's, before you do a regear, consider applying that expense to a Dana 60 swap. THANK ME LATER! 😀
 
It's on my radar for my 09 Tacoma. I have 4:88,s with factory e-locker now but am considering the Dana 60 for it's robustness.

You might want to consider the upgrade before your factory unit breaks. It cost me an extra $1500 in towing and repairs to make my pickup drivable as a FWD only option while traveling on I-40 in TN, so I could get it home.

The rear pinion in my 2nd Generation Tacoma was simply too small to support the strain of a 4.88's in the long term. It spit its teeth out and required me to pull the pinion and ring gear, and all the debris out. No 4.88 gears were available at the time so, $1200 of labor, $3500 for gears, and two weeks in a motel was not a reasonable option. ~$4700 in repairs, plus towing and motel costs, easily pays for a new Dana 60. With time, you might find a used one for a good price.

I'm looking at East Coast Gear, can get complete unit for around $5000. I too am running 4:88
