This old thread from Pirate 4x4 explains the difference between a CV and non CV yoke. @jamesroney is right, when you've dealt with them for years you can spot the difference from across the shop LOL.

Yeller, getting ready to order a new driveshaft. I see WH has them in multiple lengths. When I measured from outboard u-joints I got approx 35". ( with the old xfer yoke). WH offers a 33.5 (stock), 34.5", and 35.5". My truck is NO lift with new stock height rear springs from Tom's. I can only assume the 35" length since I'm running light, a 1/2 cab roadster, and nothing in the back except a spare. Does that make sense and do you think I am ok with the 33.5" stock shaft or should I opt for a longer one? Thanks.

I would think unladen with sticky replacement springs that the 33-1/2 would be fine. Should have more than enough slip to make up for any measurement issues.

Sticky? Ok, if you go by what WH says on the webpage I should be getting a 35.5” shaft which I would think is too long for my application. I don’t want the shaft halfs bottoming out if I hit a big hole. Maybe I will split the difference with 34.5”. Thanks for your input.

Sometimes should read closer before I hit post. Stock lol.

Does anyone know if there is a difference in length between a CV and a non-CV yoke?
If so, I certainly wouldn’t be measuring for a CV driveshaft with a non-CV yoke.

FIXED! Thanks to all for the assist with this issue. New correct yoke, new correct driveshaft from WH (34.5"), new rear output shaft bearings. Rides smooth and quiet!

Fantastic news! Thanks for the follow up.
