I fully understand cv vs u-joint. That is not the part I don't get. A u-joint can give smooth power transfer too, the main thing is the angle they get turned at. However, the turns will still feel jerky due to the tire on the inside of the turn moving at a different speed than the tire on the outside, not the knuckle that connects it. Now, if you are turning real tight, the u-joints can make it a bit rough, but the factory limited the turning radius to prevent joint binding.

When stuck in mu or snow, all wheels straight , get on the throttle power delivery is smooth. Turn the steering wheel left or right you would expirence a "chatter "from the front axle due to fluxuations in wheel speeds due to the cross section of a u-joint. Ultimatly catastrophic to u-joints and axle shafts due to shock loading and unloading. A CV shaft has a full range of motion without the fluctuations of the cross section of a u-joint.

I see what you're saying... With the wheels at full lock the ujoints will "pulse" compared to a cv joint

That phenomena only happens at full lock. I agree that will improve with cv joints. That is the only time it will though, as I had mentioned it was due to the angle of the joint. That is what I didn't follow, as it is only on full turn, partials will not be noticeably different.

Glad we are all on the same page now....
I'm looking forward to getting the parts. I picked up a new set of headers too. The old ones are rotten where the down tubes meet the collector flange. Hopefully late next week I'll be able to throw them in. While I'm under the truck going to have a look at a few other minor issues. My basement is starting to look like a parts store haha

I also know what you are getting at about the double cardan in the knuckles, my big truck has it...allows for a 42 deg crimp angle and no steering wheel jerk on at hard turn...unless the front axle is locked at the diff.

What part of Alberta you at?
