Thanks guys. I'll be honest with you, as a newb I won't be stressing my diff cups to the point of breaking any time soon. My biggest enemy is the wall and my lack of experience. I do want to try 2 diffs in the TC4 as an experiment when we start running asphalt.
I bought a complete rear diff out of a never used TC4 Club for $18. I'm just going to swap it for the front diff. I'll experiment with it over the summer/fall. As I get better or put in enough time/wear on the components I can then upgrade to the lighter better parts. I'm trying to also reign in my spending since I've now got the TC7.1 to think about.
What is everybody using for diff lube? I've got a tube of the AE diff lube but I've read that there are some interesting alternatives so thought I'd ask. Thanks!
I've never broken a plastic outdrive. But they do wear out pretty quickly. They're pretty cheap to replace so if you're planning on sticking with them, get a packet or 2 of spares.
I stick with the stock AE lubricants.
