I'm a new Summit owner, relative novice to RC.
I think my sons and I (okay, it was me driving at the time, but I enjoy spreading the "fun") blew up the front diff last night.
We were running in some grass, and I was driving over a taller clump that was hiding a rock from my view. The rock hit the center skid plate dead center, and was heavy enough to stop the truck and throw it straight back. As soon as I hit the throttle to go forward, I heard the grinding and clicking in the front end.
I have not yet disassembled the diff to inspect the damage.
I've ordered a new diff from ebay. I'm planning to order the parts to rebuild this diff to have as a spare for "the next time".
I don't have a LHS, nor do I have a local club with any experienced RC'ers to tutor me.
I'd like to double check with everyone here to see if I am making the right diagnosis so far.
I am also wondering if my parts list for the spare/rebuild is correct:
5681 Carrier, diferential
5382x Gear set, differential
5678 Gear, locking diff output
5379x Ring gear, diff pinion
I am planning to put 50k weight oil in it.
