Hey Tim,

I spent tonight reading through the internet to gather information on replacing the U joints and CV Ball Seat (I believe is what the ball between the 2 u joints are called?).

The most recent informative post on this was from 2019 between you and another member that was last active on 2022.

This is the link to that post: Double Cardan rebuild

Now what I'm concluding is that Tom Woods sells robust replacement double cardan driveshafts for our rigs for now around $550.

Alternatively, DIYers can try to frankenstein something together, but if we're not using Autozone parts that allegedly fail within 10k - 15k miles, people go for the following Neapco parts?

(2) Neapco 1-5800 :: U Joints for double cardan
(1) Neapco 7-0407 :: CV Ball seat

I was curious if you could confirm this information, as this would save around $400 for this job if I didn't go the Tom Woods route.

There's no post that confirms this for sure other than the link to the post I provided above that no one else has responded to confirm with.

Curious if anyone else has had luck with the above parts or alternative parts list that would get this double cardan rebuild done?

It's been a long time since I did any research for this job. I don't know if those are the right parts or not.

Thanks

Just wanted to say thanks for all the work on those videos! I'll be going through my latest project purchase over the next month or so getting her back into trail worth condition.
