Re: Service Manual
Welcome to the garage.
Any reason you don't want the factory service manual? I'm using it and am very happy with it. You can fairly easy download it from the web, just do a search on google or so. There are free manuals and some where you have to pay a bit.
Front brakes are easy to do. Your front rotors are probably warped? I think in 2002 they changed from the Teves calipers to Akebono, which should give at least less problems of warping.
You should have a look at the front drive shaft CV joint boots, they normally dry out and and open up and all grease will go out/dirt going in. As far as i know you can remove the hubs without destroying them.
Regarding flushing the transmission, the opinions are divided. The good thing of a flush is that most of the fluid will be changed, whereby when you just drop the pan, you won't get the fluid out of the torque converter (around 4 qts). But some people had bad experiences after a flush. To my understanding the problem is that fresh fluid has strong cleaning properties and would remove accumulated dirt and bring it to places where you don't want them to be. Best is to keep the services at the right intervals, so that no dirt buildup occurs.
Serpentine belt is very easy to change, use a Goodyear Gatorback for a quiet run.
