Should I use? 75 f100, 9" rear. Just wondering what you guys recommend for u-joints. I'm lookin around at autozone advance auto napa and oreillys. I don't want on that will wear out in 5 months like that one that I put on there last year.

 

Spicer is what I used last time, from NAPA. Always have done OK.

 

Spicer....will cost more but will hold up better.

 

Spicer if you can get em locally, or else neapco makes a nice joint as well. Anything made in the USA will be leaps and bounds ahead of china stuff.

 

there's nothing showing up for spicer at napa. Are the duralast golds at autozone china? What about these?NAPA AUTO PARTS)

 

I have a Duralast Gold on my rear diff. It's garbage. No zerk fitting and it's made in Ch1n4. Get Spicers and don't let them sell you on the supposed lifetime warranty on the Duralast... turns out it's a lifetime warranty - ONCE. You blow it up once, they replace it once. Then you buy another "lifetime" warranted junk joint. Just go Spicer and don't look back.

 

I've got Spicer 1350 series (part number 5-178x) joints on my rear driveline, but I also had to have a custom driveline made in the first place. Since I was adding the Gear Vendors overdrive unit on the back of my transfer case, I eliminated the two-piece driveline, and had a beefier one piece unit built. Since I had to do that, better U joints were in order as well. The upside is that it eliminated three potential failure points (two u joints and the carrier bearing).
