I’m laid up at the moment so I could use a little info. I need new u-joints for my ‘87 f250, 351ci, automatic, two wheel drive. Checked RockAuto and there seems like hundreds!

How many do I need? I’d think two, one rear and one front or is there a third? Then of course there are apparently size differences? They’re freakin u-joints!!!

So how many do I need? By the way I’m fully stocked on sarcasm...

Motor Master part number: 3437-FD front universal joint,
Center universal joint: 3437-D,
Rear: 3437-C,
MOOG: 354 front&rear,
Center: 434,
There's 3X universal joints,
ANY automotive retail store will carry or have them or a driveshaft shop.

Changing them is not one of my favorite repairs. I always think a helper to keep everything aligned is good.

I always paint witness marks so I can ensure the driveshaft goes back on correctly. I’ve always use a vise to get the joints out but I did pick up a 40 ton press awhile back from PA clearance sale for $200 CDN so I’ll have an excuse to finally use it!
