Time to fix stuff...

[rmb1393]

I have a 2002 f350 and it has just over 126,000 miles and when i brake i feel a subtle pulsating in the front end and i have had the abs light on for a while. I had it scanned to the sensor in the rear diff. Also when i drive down dirt roads or any bumpy road i can hear a click in the rear end after a bump... i think the front brakes may need pads or rotors and maybe new shocks all around. but do i need bushings as well? what are some good tips to diagnose suspension/brake problems? I am in college and dont have money to fix something that doesn't need fixing

I am a newbie and this is my first truck and i waant to do things right the first time. Please any help would be appreciated!!
