It is kind of a PITA replace sometimes, it is just the space you have to work in and it can be difficult to remove but by no means something that a DIY cannot do.

As far as symptoms go... loose rear end, rear end steering. I have not been able to easily tell if it is going bad untill removed. some say take a prybar and try to move it around to get an idea if it is bad but I can nevertell... if it looks bad, replace it it is only like 60$.

If it dosn't come out with a hammer get a bigger one!

seriously, soak it in your favorite blaster like product and try to get it out... if not heat in and start banging.

A good way to check it is set the handbrake and then have a buddy try to roll the truck back and forth by grabbing the rear tire (it takes a good bit of effort). Then put your hand on the link, if you feel clicking or slop you need to work on it. Its also a good way to check rear suspension bushings to find the rear steer and all mentioned above.

i just want to confirm you can get it out without having to take the entire a arm out. it does seem really tight in there maybe taking the gas tank out will free up some more space. i have heard there is an adjustable ball joint? whats that about?

The adjustable ball joints have a large slot in the top, you can disassemble them , regrease them and tighten them down to take up any play
The thread may well have siezed When I did mine I ended up taking the bal joint off.
Chock the wheels, support the chassis on stands with the bulk of the weight on the stands. remove the large nut securing the taper of the ball joint and give it a sharpish belt with a large hammer on the axle housing that contanis the taper. Then remove the two long bolts that hold the ball joint to the A frame. the ball joint should be free from the rest of the truck now. If replacing the ball joint try and get one fitted with a grease nipple thy last for ever if greased once in a while
You'll need access to a press of some sort to remove the ball joint from the housing attached to the A frame

IT would be easyest to just unbolt the joit holder from the arms and then the 30mm bolt from the axle. I have changed 2 of them and both times I needed a torch to heat it up then beat the shit out of it with a BFH...

revive the thread. I am going to replace this the coming weekend. I think I will remove the entire a frame? Is there a bushing where the bolts (2) go through the frame? As far as the ball joint is concerned is it pressed into the rear a frame, or is it pressed into some type of "holder" that is pressed into the rear a frame? I am anticipating new rear trailing arms also. I have begun a regimen of PB Blaster, I am not so sure it will help very much. Thanks for the never ending insight.

If you are going to replace the ball joint on the rear "A" frame over top of the axle you will need to jack up the rear of the vehicle so you have access to the nut (Jack on the frame not the axle). If I remember right a 33mm wrench fits. Once you get the nut off take a big hammer and rap the edge of the mount and the ball joint should come loose. after you have it loose there are two long bolts that hold the part that the ball joint is in. Remove those bolts and you now have the ball joint out where you can get to it and remove it from whatever the heck that piece is called. Anyway that's how I do it. Good luck
