It sounds to me like you are limited to your product selction by what is available at your LHS. If this is becouse of dependence on family for your needs, perhaps you ought to sit down with them and show them the logic and availability of options online. Doing your homework / research and providing that as documentation may help. The logic being that if you must replace a RC component and lay out the cash you might as well get the component that is going to get you the greatest life expectancy and all but eliminate future needs.The ability to order online opens up the market in ways that will permit you to get the products that best satisfy your needs.
I have heard the definition of insanity is: to do the same old thing over and over again and expecting to get different results.
For Diff componenets here are my suggestions. The UE products are available through Monster Mike.
If you want to stick with stock Diff gears, try
these cases
If you want the whole shabang try
these.
To all concerned your selection of hardware IE..screws will make a huge fifference in life expectancy. Stick with class 12.9 steel Hex screws only and try to utilize Cap head screws everyplace that they will not cause binding. Button head screws next, and flat head only as necassary. For Suppliers of the highest strength kits try
Tony's Screws Check out the kits or individual packs.
If you prefer to buy in bulk try
Mc Masters Look on the right for Fastening and sealing, then socket head cap screws. Killer sight for all your hardware needs.:cool:
Everyone has an opinion and this is mine.
