Can i do it my self, tying to save some cash!

You can replace the radiator. Its easy if you have a basic set of tools.
You can download the FSM from iluvmyrx7.com or fc3s.org and buy the haynes book.
If you plan on keeping the car a long time, it would be good to upgrade to a higher quality radiator.

But, since you are trying to save money, a cheapo parts store radiator is good enough for an NA. While you're at it, buy a new Mazda thermostat/cap and remember to use the same coolant that the car came with.

Ujoints aren't serviceable. Some driveshaft/axle shops can replace them. May/may not be worth the aggravation to try to replace them yourself. Plus, there are usually some on ebay/salvageyards/partstrader......

Thanks for the info, I think i am sticking with a stock Radiator for now, used i think. I have a shop that will do the drive shaft for 80 bucks. And i found one on ebay. Hope it works out.

get yourself an aftermarket radiator as long as you're replacing it. All aluminum.. these cars run hot, and you can't go wrong keeping them cool.
