It looks like I will be in the market for new rear u-joints. Is there a preferred brand for strength. The truck is used for some off-roading and sand and I pull a travel trailer if that matters.

Truck is a 2008 F250 Fx4 with the 6.4 diesel, I believe it is the 10.5 Sterling axle.

 

Rear is the Sterling. Spicer or Federal-Mogul are pretty good. Don't think you can really go wrong with any of them as long as they are greaseable.

 

What size is the rear u-joint, 1350, 1410, ??

 

X2 on the Spicers!!!

 

check out dynatrac.com fully rebuildable, greaseable, chromoly stout

 

Spicer life (solid) is all we use.
