Today I finally got my brakes set and I finally was able to play with my truck for the first time in a month. After about three tanks my dogbone fell out of the rear axle and starting binding on the rear axle. This has happened to me several times since I got the truck and have to replace 5 sets of rear axles. Is there any solution to this? I do plan on doing the TMaxx shafts upgrade but then I will also have to get new wheels and tires which will be a little spendy which I don't have the money for yet. Oh also I do have o-rings in my diff cups. Any advice would be great
