What GEAR Instructions don't SAY... | Full Re-Geared Break-In Process and Transition Tips

[@Robert-Jaudon]

Great video as always. I seriously appreciate your thoroughness and spelling things out for me.

Let me know if you want to get rid of the redline oil. Cheers! I went down this rabbit hole with my 17 trd off road 4Runner a few years ago and I haven’t had any problems. Like you I was very lucky to have a good shop close to home

I bought a 2016 tundra with 37” tires. I did a test to find out what my gear ratio was and it’s still the factory. I get 9 mpg. I would like to get the mpg back to original or at least close. What gear ratio should I get

[@cecilmartin8110]

Good video man. Thanks for the info. Re-gearing is in the future.

[@OverlandEngineer]

For sure! I'm so glad I did, should have saved and did it sooner.

[@FJREY]

Good video. I run SIERRA gears that are polished that allows me not having to "break-in" my 4.88 gears. Inquire more with The Rear End Shop in Livermore, CA.

Excellent video with great info, thanks!

[@OverlandEngineer]

Glad you liked it!

REM is not a coating, it’s a tumbled polish in an abrasive media.

[@davidk6668]

I was told your front diff gears are turning even in 2 wheel drive so will be breaking in when you are breaking in rear.

[@coolarmyguy0288]

Not in a Toyota they have a electronic disengage system in the differential. In a gm or the older jeeps they are still spinning

[@brad1367]

Wrong. Breaking in happens from the force from driving the gears not the motion and friction.

[@lucasr5675]

very good content as usual! I just bought 4.56 but I am bit worried about the break-in period. The shop I go to is so far away. Wondering how many stops I need to do during the cool off.

[@thegiant573]

So OEM gears are not broken in like this so why the aftermarket gears? Is this a Toyota thing? Never did any of this on my Chevy.

[@OverlandEngineer]

Well I presume OEM gears might be pre-run like Yukon does on their gears. Its just what the install instructions talk about but it does beg the question if a new car gears really should be broken in similar to a new engine...I don't know the answer to that.

[@brad1367]

wow you not smart

[@roblayman6630]

Just got 4.88’s on my ‘23 Tacoma. Really makes it peppy ! One thing no one ever mentions is gear noise. 55-65 mph. Kinda annoying for sure. East Coast Gear installed mine. They told me all aftermarket gears do this. Didn’t find this out till after I had gears installed tho. Just an fyi !

[@OverlandEngineer]

It depends on the gear makers, many don’t make noise and it can be dependent on whether the companies pre-break in their gears before selling them to the customer for another break in. The noises can exist early on and then subside as the gears break in. Proper break in should heavily minimize or even remove those gear noises. Which gears did you get?

[@ricksmith7659]

That's not true. If your new gears are noisy they're not shimmed correctly. That shop doesn't want to admit they F uped

[@justincmw]

Look up baton rouge industries L625 gear oil

[@ReimerKeith]

Why couldn't you use the Redline?

[@OverlandEngineer]

Its synthetic and OEM 75W85. Both against the recommendations of Revolution gears to use non-synthetic and 80W90. Plus 80W90 is much cheaper so switching to that will be nice going forward. I'll likely swap fluid every year.

[@tpharo34]

Developers of OTT are in Alabama at least one of them.

[@ken85225]

Jeeezzz.....REM is the answer.

[@TheShooter466]

Ah, Yes i'm very familiar with linear power bands thanks to Adam LZ

[@LandCruiserTEQ]

You're complicating stuff to much

[@cristopherandino3000]

You are right. it looks complicated as hell. I'm too distracted to keep track of that nuch driving time and speed. I would rather stay at 285/75/17 (33.8") and don't worry about regear. There is too much money and factors involved just to run 35"s.

[@adriandevora4090]

boy you talk alot
