I have a V5 Kraton 6s BLX. I have replaced the front and rear bulkheads with stock ones. I didn't see anything wrong with the original ones but I was worried there may be a tolerance issue I couldn't see. I have also replace both gears in the rear diff Pinion and spur 3 times. I checked the bearings, made sure to shim the diff. I don't even bash this thing very hard. I accelerate hard and brake hard up and down the road in front of my house. I'm at a total loss here. The first rear diff went out when I went to a clay track. I noticed it started to grind when braking after the front straight. Is braking what's causing my diffs to destroy themselves? Since the clay track I haven't jumped it at all and have just drove it hard in and out of my cul-de-sac.
