So I took my 2004 4 door 2wd on the interstate after I replaced the old tires 235/70 R15, I went with 235/75 R15 with a thicker sidewall and overall gave it a better look and a very slight lift ~1". Anyways I got a shake in the steering at interstate speed. Checked underneath after I got home and sure enough every boot on every fitting is busted and loose. The shake was the tie-rod. Anyways i found a full steering kit (including new upper control arms and lower ball joints) for very reasonable and decided to go ahead and do wheel bearings too while I have it all torn apart. Wish me luck since it looks like its going to be close to 100 degrees this weekend here. I'll try to take a few pictures as i do everything. The whole process has been videoed and posted on youtube numerous times so I won't do a write up.

After this a spark plugs and wires I should have all the maintenance done on the old girl and can just enjoy it for a few years I hope.

Added Hitch Receiver
Shocks all the way around
Vacuum lines

LED Light Bars
Spark Plugs and Wires
One Last coolant flush (Hopefully)

 

Good luck and keep us posted.

 

Steering and suspension replaced. Getting the lower ball joints to seat all the way was a real peach. Managed to get that after a few four letter words. Then on the passenger side, I dropped the lower control arm a little fast and... out comes the spring.... that was a chore to get back in place. I didn't take any photos since I was in a crunch to try to get our shop area free for my brothers farm projects.

biggest tips I have for anyone considering this - gear wrenches are a life saver on the upper control arms. You are going to need a ball joint press kit for the lowers, and possibly a very large socket to help press out the old ones. Pretty much need every metric wrench you own 13mm and over. Mostly 13,14, 15, 18, 19,and 20. A second set of hands comes in handy when getting the ball joint press setup, otherwise its pretty much a one man job.
