Has anyone replaced a lower ball joint after one has failed. I have been able to remove the socket from the lower control arm however, I cannot seem to get the ball out of the knuckle. Any suggestions? I figure there is enough knowlege on this site that someone must have dealt with this situation.

jack up the car and put a stand under the sub frame or something alike, just not the lca,

then with the nut removed, you need a very big hammer to hit the spindle or the lca.

just dont hit the threads on the old ball joint, it may become hard to remove it from the spindle..

and are you replacing the lca, or just the ball joint?

The failure was catastrophic. The ball seperated from the socket. The socket has been removed from the LCA and that is fine. What the problem is, the ball is still in the knucke and I have tried wedging a couple of forks together and tried that plus I have a zip gun ad that did not work either. How big of a hammer do you need to use. I had a 2lb mallet and it didn't phase it

hmm now im out of ideas..

i think you mentioned that you used an air hammer with a chisel end on it, that will usually seperate most things.

im not sure what this is going to take to get it out, all i know is sometimes they can be a real pain in the a$$

Thanks for the ideas. I am going to try a 5lb sledge tomorrow. I would hate to have to tow it somewhere and have to pay someone to finish it. Especially when I have most everything done.

I used a pitman arm puller, 6 bucks from Harbor Freight. I used it to get the LBJ seperated from the knuckle/spindle, the end links from the swaybar and the knuckle/spindle, and the tie rod ends. It worked for all of them, I tried the tie rod end fork, two or three of them actually, the air chisel with the rounded proper end bit, the pickle for attachment, a BFH and an even bigger BFH and just made a mess, but not so much that I couldn't get them off with the tool pictured below. I had the nut still on it so I didn't kill the end of it.

it wasn't the easiest to get on the LBJ, I had to SLIGHTLY bend the dust shield out of the way. I did this both on the 89 with the old knuckles, the 97, and the 89 with the new spindles (so I could do a brake swap), but it took about .0002 seconds to get them apart (everything I used it for) or it slipped off and I had to start over (but it worked 90% of the time the first time).

Job completed ...The Pitman arm puller did the trick. However, I still needed to use a BFH on the top plus heat to get it to break free. This is an abysmal job if the joint seperates.

When I Did My Cougar The Ball Joint Seperated Also,the Ball Stud Came Out Of The Spindle Easily For Me Shocking,but That Darn Camber Bolt Gave Trouble. I Replaced The Whole Lca. When I Did That The Bolt For The Lca, The Friggin Head Snapped Off.i Took A Propane Torch ,center Punch,and A 5 Pound Sledge And Made It Come Out.it Took Me 45 Minutes To Do It Was Pia But I Got Her Done.

Are you replasing the ball joint? I had mine pressed in at Firestone. The only place I could find to do it.
