The front end of our truck has been in need of some TLC for a while now. It started last fall with a nice clunking when the truck hit good size bumps. Turns out the driver's side wheel bearing was done. So back a few months ago I did the wheel bearings and seals, both drivers and passenger side. Clunking got better but was still faintly there. Well a month later it started getting worse so I took another look and it turns out the driver's side lower ball joint was also gone, so yesterday I finally got around to changing it. I did a fair amount of online investigating before ordering anything as I didn't feel like parting with all the cash required to purchase the OEM ball joint / LCA assembly. After a couple of days of research I decided to run down to the local NAPA and order two MOOG K500017 ball joints. The driver's side seems to be the only one gone but I like to replace front end components in pairs so I got two, esspecially with a high mileage truck. I tooks pics (sorry if some are blury) of the entire process as I found online information to be sort of scattered in bits and pieces. Perhaps I just didn't find what I was looking for, so hopefully this thread isn't a waste of everyone's time!. The following is the step by step prcoess of how to R&R a lower ball joint on an '07 FJ Cruiser.... Hope it helps!
