Only took me 87 videos and three weeks to find this genius on YouTube!

[mikehowell]

I have been a mechanic for almost 30 years and you just taught me something new! Thanks a million

[mr.zeugrav]

this is the kind of video YouTube should feature.

[jakebrakebill]

Been doing axles for 50 years, I never claim to know it all and crazy how you can still learn something you didn't know or at my age forgot. Lol.. Great job on the video.

[jasont]

I’ve had Jeeps for 14 years and you taught me more about gears in 20 minutes.

[demetriusstump]

I knew absolutely nothing about gear ratios before this video. I feel like I need to swap out my rear-end now thanks to this guy! Amazingly detailed information.

[heartmanable]

This is an example of someone teaching you who knows the subject well. Thanks for clear and to the point explanation.

[lekhank]

left for almost 6 yrs and this man is still taking me to college... thanks man... appreciate ur time and teaching.. ty..

[tommyd]

If you are wanting to learn about gear ratios then THIS is your video to watch.. It is pretty simple when the person explaining it to you really knows what the heck he is talking about..
Most excellent video dude..

[Angietrainingdogs]

This was the best explanation and mathematical breakdown I have ever come across.

[RNTV]

Wow, I’m a ford technician and I learned a lot. Very intelligent. Thank you for the gear ratio lesson!

[sonnytrejo]

I didn't plan to watch this entire video.... But after listening in for about a minute... I was suddenly captivated.

Your explanation was very thorough and elementary in lecture... So easy to understand!

Fantastic video!
Thank you for all the knowledge!!

[atlmacman]

You're an excellent explainer. I'm a college graduate but have very little mechanical knowledge, and I believe I understand about 90 percent of what you explained in this video. Thank you very much!

Thanks for posting this tutorial. I have a 1989 F-350 7.3 L diesel backed by the three speed C-6 transmission. It had 3.55:1 gears and 215/85r16 tires from the factory. The previous owner said he put in 4.10:1 with 225/70r19.5.

The new tires and gears both are taller and the engine screams at 3, 000 RPM at only 65 MPH. I was going to go back to factory 3.55:1 but after doing the math you explained, I should go to a 3.73:1.

Thanks! I hope it gets my RPM's down to around 2, 000 RPM's at 65 MPH....or 2200 at 75 MPH.

For those that care, I'll post the result of my change.

[papabear]

Appreciate this video even 8yrs later!!!

[thundercat]

I couldn’t find any videos on YT that could explain gear ratios! You’re the only guy that could explain it! Thank you!

[KrushimTV]

As a scientist I have to tell you your videos are great. Very detailed and well explained. Your thoroughness makes these vids extremely helpful. Sometimes a person thinks they need to know one thing but what they really need to know is something different that they haven't considered or were unaware of and your videos can point those things out. Hope you keep making them this well.

[PanchoVillaMSK]

Easily one of the most informative videos I've ever seen. Thank you.

[williamcritcher]

This was very helpful. Thanks. I do want to ask if you can do a video class on differential rebuild/setup. Start to finish. Measuring for all the shims, back lash, preload, what tools, etc. Since you are a great teacher and most of us can’t go to a school for this training it would be a GREAT service to your viewers. I know it would be long and hard but I believe in you, you can do it. Nobody else has, I’ve looked. Again THANKS.

[tripleseven]

An excellent video for someone like me, who’s never been trained or exposed to auto mechanics…Very educational, thanks!
