Duh? Just giving you crap...

I think of that when I see those big jacked up trucks and extreme angles on the u-joints. Same phenomena explains why solid front axle 4x4s shudder on hard turns.

that's kinda why I put it here. so rookies can get a visual aid through their helmet while licking windows.

I think another place this can be seen/felt is in a short wheelbase dump truck. We had a single axle 5 speed in an IH dump truck decades ago, the driveline was short, so the driveshaft dropped quickly. When heavily loaded, this learching in the shaft and joints was very pronounced....it was not the clutch, and it was fully engaged.....

That guy really messed up his credit card...

IdIoit Thanks for the video that was informative.

One of my favorite videos. Tells you why 4wd lurch when turning on a hard surface.

One would have thought this was not possible but sure nuff. Science does not lie. Saw this a few years ago here but still current for today's fools lifting their rigs.

Cv joint" just sayin"

Just sucks that CV joints are inherently weaker... Rzeppa style at least. Broke one on my neon... seen them fall out the back end of a GTO on the track.

Freeze-frame it within the first few seconds, and you'll see that the joints are already just slightly out of phase. Evidently not enough to be noticeable.

I wonder if that's one of those new chip-embedded credit cards.....

 

[BDCarrillo]

The change in velocity of the output shaft is relative to the angle of deflection, so within a couple degrees (ie, normal vehicle operating range) the difference is essentially negligible.

 

[IDIoit]

minimal, granted.
but it does reak havoc on your u-joints.
