I will not be able to do this myself. So my question is my Grand Cherokee is at 120,100 miles, the CV boot and joint must be replaced. I also need to replace a rotten tailpipe due to an exhaust rattle. Will it be safe to drive through the winter or should I have this fixed immediately. I'd rather not lose control of the left front wheel. If I fix this the engine block and tranny are good how much more life will I get out of this truck, or should I trade it in the spring.
