Answer
Nadeem: I would say your problem with the fog lights would be a bad relay or a bad switch that controls the fog lights. Something is getting hot and so the computer is shutting it down as to save the wiring. So you will have to either find that bad relay so replace the relay that controls the fog lights with a new one. Or else replace the switch which turns them on and off. To get the wheel bearing replaced the shop is right, it would have to replace all the bearing not just one set. If you are going to replace the bearings, you need to get all of them together. So that they are all about the same age, so they age together. So you need to do the whole set. Other wise you do one set of bearings now, and down the road maybe but a few weeks another set will go. So then the shop would have to charge you for doing all that work again. It is better to be safe than sorry, I always say. Now the I wouldn't be changing CV joints but rather stay with the ones that go with your car. Because you have no idea how all that would wear, Mitsubishi has one kind and say Honda has something else. It might go together ok, but will it last? Or would it mess something else up and end up costing a whole wagon full of money down the road. Why not just stay with Mitsubishi parts or something that is made for that kind of car.
