Hey guys, I am new to the forum and have already posted in the new members forum introduceing myself. I recently picked up an 01 F-250 (4x4, lariat, 7.3, low miles) and I have a few questions about it. The front end makes a noise when I hit bumps, and I inspected everything. I came to the conclusion that its the sway bar bushings and then from reading on this site I found out that thats a common problem. I work at "oreilly auto" and we dont list shit for sway bar bushings in our computers. Autozone and advace do, but they have several different ones listed and I dont know which ones I would need. I would really rather get a better quality aftermarket set of bushings if anyone makes them. What are some good ones, where can I buy them, and how do I know which ones I need.
Also, I need a tail gate (truck came with out one) and a few people have told me that the f-150 gate will fit, is this true? I would think It would be easier to find one off of a 150 anyway. Thanks in advance for the help guys.
