Man, I love a good video that's no B.S., to the point, on topic and detailed with not only the relevant information you need but all the information you need and that's it. Great work.

Best driveshaft videos available. Years ago you sent me a new driveshaft and teeshirts that said show me your shaft and my shafts a woody(for my wife). Shake that shaft is a new one

Super informative. Thanks for putting the time in to explain

Now THIS is a good video. This can really help people dealing with those issues. Great work

I had a vibration for year's. Checked everything mathematically, changed shims, ect. Turns out the shop that did my SYE didn't tighten the front yoke all the way.
GRS noticed it during a inspection. Once tightened , no more vibration.

This vid helped me a lot to find out what the .... happend yesterday at my Ford Capri. The unbalanced drive shaft test reproduced excactly the noise i heard under my tunnel (at 2300rpm machine revs). It stopped immediately when i hit the clutch and my speed dropped from 160km/h to 100km/h. At normal speed, nothing noticeable. Thanks a lot. 👍

Well, this answered all my questions. Thanks for the great, informative video. All the information one needs, and nothing more. 👍

Best video on the internet for this. Excellent explanation

I just shortened one of your shafts, the welds were beautiful and the phasing was laser-perfect.

We switched from 308 gear ratio to 373 in our 78 GMC C15 4 years ago for pulling, and developed a 58 mph drive shaft vibration and a u joint life of 2000 miles. We are finally down to the driveshaft. Three custom drive shaft people told me that a 75 3/4 inch steel drive shaft is too long for these gears. i just found an aluminum shaft for it, I sure hope that fixes it. Loved the video! Thank you for sharing :)

Thankyou for sererating the 2 sources of vibration 1/ angle imbalance vs 2/ actual weighted imbalance

Superb video, a markerstone for getting to the point. Thank you

I love the background music! And this helped me diagnose my infinit g37 driveshaft (custom built basically new for high hp application).

Great explanation and a lot to learn from! Thanks

Another Aussie and new sub ... Robby sent me. Thanks for helping our mate Lynchy... Mega Kudos

Oh, I eventually found out what was causing it, back at the beginning of 2022 I replaced the Guibo which led to me replacing the centre bearing, fitting the new Guibo made the vibration worse but the tailshaft centre bearing kind of separated itself from the rubber insulator & it was a V6 one whoever made the tailshaft fitted, they have a different offset to the V8 centre bearing which led me to believe me that was causing the vibration, it probably was giving me some vibration to some degree.

I have even replaced the universal joint as I thought that it was binding but I kept both parts which I have refitted into the car early this morning, I mentioned that I have refitted because I tried replacing the Guibo on the rear differential which had some slight splits in it but I kept the old one.

Well, I placed the rear of the car on jack stands then I checked the tailshaft while I ran it in first & second gear, the rear section was good but the front half was throwing a wobbly at idle speed.

So I switched the engine off then I got a dial gauge then I checked for driveshaft runout, there was 0.4mm or 0.016" of runout at the front of the shaft up near the front tailshaft flange, it looked like that the Guibo may have been warped as well.

I decided to take the cheapest route, I fitted the Guibo which was fitted onto the rear differential yoke & tailshaft then I fitted it up to the front, I ran the engine in first gear & checked for that dreaded wobble which had almost completely diminished, it was a major improvement.I test drove my car this morning at about midnight & the vibration in second gear was gone.

Buying the cheap $55 AUD Guibos are a hit & miss affair I think so I can either take my chances with them or pay 2-3 times as much money for a reputable brand of Guibo !

Thank you for breaking down possible causes of vibrations. Very sad to see on your website that you're no longer making single piece shafts for Tacomas. Not looking forward to screwing around with axle shims and replacing yet another carrier I WOULD SIGN OFF ON A WAIVER FOR A SINGLE PIECE SHAFT!

I put new u joints on my rear drive shaft because I had to take the transmission and transfer case out.

Now I notice that at 75+ there is a vibration feeling. I tried my best to mark the drive shaft but because this was my first time I think some of the components are not longer in the correct position.

I also don't know if those new u joints are good because they felt kinda tight even out of the box.
