Would 75w140 Redline gear oil help the needle bearing live longer or even prevent replacement in the front axle on 23 Tacoma 4wd? I'd just use the same in the rear if that would be better.

Both: are wrong for the diff;s
If you are trying to stop known damage due to lifting the vehicle a thicker oil will not make things better,
it will just be quieter when it blows apart........ better bearing made for more stress would be an option
But a GL4 90 would do more harm than good........ Red Lines recommendations
Use what is the correct weight and spec,....
This is the 75w140 use and design.....

- Contains extreme pressure additives like our 75W140 GL-5 oil, but lacks friction modifiers to balance slipperiness
- Popular for historic and vintage transmissions, like Mid-1930s to early-1950s synchro-equipped gearboxes in cars and trucks
- Helps with noisy or rough shifting in troubled A-833 Dodge/Plymouth 4-speed transmissions from 1964 to 1969
- Option for noisy transmissions when mixed with 75W90NS or MT-90 to bring viscosity level up
- Also used in clutch-type limited slip differentials in racing for maximum lock up-some users add Limited Slip Friction Modifier in small doses to customize slippage
- Non corrosive formula, safe for use with all synchro materials

I have Redline 75w90 in the front right now.
I thought they failed on stock trucks too. Often earlier

Not sure, about the bearings.
Like a lot of failing parts in the earlier models they were upgraded to avoid warranty issues.
Looking at old and new part numbers over the years will sometimes show a hint.
Toyota was good about that; we can just hope the 4th gen buyers get the same grace.

I use GL5 in the diffs
GL4 in the MT and Transfer

I think all 3rd gens use the same needle bearing in the front axle, atleast that's what Rockauto shows

They do use the same part.
the point is have the needle bearings changed in quality over the past 8 years.
Just like the cross over manifold on the 3.5 V6,....... it is the same part in appearance.
But it has been upgraded / improved so it does not leak / fail and thus "Toyota" changes the part number (superseded the number).
Does rock auto change the number,..... most likely not.... they either get it from Dorman or another copycat
Is that copy better than OEM, most likely not.
I dont buy cheap parts (my choice) as they are not better (my opinion)
Just like I don't buy cheap gas (my choice) and I won't be getting a code in 60-80,000 miles telling me to change my catalytic converters because they have become clogged with crap. (yeah)
Two things has never changed, people like "bargain's" and.............. you get what you pay for.
Rocks, life and reality have one thing in common,..... all are hard to handle sometimes.
Excuse the rant but,....
Why buy cheap / non-OEM parts BUT spend money on premium oil or lube to "attempt" extend life and protect those cheap parts??
(Premium parts and quality lube will give you the best performance.)

I am looking for the best lube foe the longest part life. I use Redline, I'm absolutely not cheap. I just am not keen on replacing a part when a change in viscosity might prevent the failure altogether, hence my question. If it does fail, I will get a new one from ECGS. I tend to buy once, and cry once. I hate replacing the same part multiple times. I have never been a cheap ash.

Sounds good,.....
ECGS is a parts distributor and repair shop, they do not manufacture parts.

I use 75w110 in the rear axle MT-LV in the transfer case, MT90 in the trans and right now 75w90 in the front differential. All changed once a year, regardless of miles..
Would the 75w140 be better for the needle bearing or 75w110 or 75w90?

GL5 is what you want for the differentials
It has additives for the high pressures placed on the metal gears.
GL4 has a lesser value of these additives for pressure and is "safe" for brass and other soft metals used in Syncros.
I would be more concerned about using the wrong lube as to damage the gears than to help extend other parts in the system.
The needle bearings will be served well by a 75w85 GL5 lube.
It is the recommended lube.
