Well found out my 2 month old non greasable U-joint are toast again.
Probably from mud and water and such. Plus I've busted the D30 joints twice last year.
What are guys running thats the strongest most reliable cause this time I'm staying away from the parts stores on this one.
I've looked around the net and really not to sure what to go with.

Wonder why I never found those? oh well as soon as funds are free I'll order up 8 of those.
Hmmm so that comes out to $360
I guess thats better than breaking store brands in the middle of no wear.

u joints shouldn't go that fast. Are you sure your not loosing roller bearings when you install them? Or could you have a bent lobe, it just is not normal. Spicer u joints are sold at advanced by the way.

Na I'm very careful with the rollers.. I add a little extra grease to hold them in during installation. Plus I've been using solid joints figuring I'd get extra strength.
