04 F250 extended cab short bed FX4. Been having a hard time finding the part #. I need for both the front shaft 3 joints and the rear 2 joint. I found # BC3Z4635A and not sure if that # is used on all 5 joints. I am trying to get the Spicer Life Series joint. The truck sees a lot of highway use and towing and snow plowing. Can anyone confirm the correct part# I might need and if they are all the same. Thank you

I'm not sure where you live put I wouldn't even bother.
I rebuilt my entire drive-line, I ended up having a private drive-line owner/shop doing it.
I even went as far as purchasing all my own Spicer U-joints as I had planned on doing everything myself, but
he was right next to my work so I ended up talking to him. He said its all about the wear and fit & sometimes he ends up going a different route. He even gave me credit for the Spicers & ended up going OEM on them.
I'd go talk with a shop if you have one around and see what they say.
To be clear I had removed all my drive lines on my truck, front & rear with 4x4 and he did them all. He even re-balanced all of them for me all in all it was only a couple hundred bucks. Granted I gave him some steel shooting targets as I worked at a steel shop.

Spicer *IS* OEM.
But I agree that sometimes it's better to take a driveshaft to a drive line shop. Especially when it involves a double cardan joint like the front driveshafts have. I don't have the patience to deal with those, and about half of the time (around here at least) the ball and cup are worn so badly they have to replace a yoke anyhow.
As far as getting the joints, I just did a bunch of u-joints and got them from the dealer. The price was about the same as Rock Auto for Spicer and I didn't have to trawl through about 150 listings, or pay shipping. The dealer we use does give us a discount, some others always want full MSRP.
I still would likeTo find the part numbers, and if all the joints are the same. I made this side to bring it to a shop and have them done. But I still I want to part numbers if I do want myself.I've done many over the years and never had an issue. Thank you for the input
You'll need to measure the width of the joints. It looks like here are 2 possible widths, either 4-3/16" or 3-5/8" across the bearing caps, inside the retainer snap rings. Either that or ask a dealer to look them up by VIN and print you a quote.
