I'll have to look at the size of the stud. You are right about being threaded or self tapping not sure which as the dodge dealer/Mech told me they were pressed in so I went to bone yard for new ones. That OTC press works wonderfully,lol. Man I hope the guy that advised me on these ball joints was right I hate to add anymore problems. never even dawned on me about the stud diameter seemed tight will look for sure thanks for pointing that out.

I bought a new upper control arm from the dealer and I can definitely say the ball joints are self tap[ng/threading. And I had to also purchase a new knuckle because the top ball joint hole was egg shaped from having the wrong ball joint installed. So good luck getting her right. I too was told by a dealer mechanic that they are pressed in. Goes to show the limits of their knowledge....

when you tighten the caster bolts did you push the control all the way up or all the way down or in the middle where it would likely be if sitting parked?

It was actually on the alignment rack when we did this work and sitting at ride height when the final tightening was done.

Thanks, I'm not sure what the shop did but it isn't right and after paying all that money I still can't safely drive it, in fact it went from shop to jack stands and been sitting there till I can grasp the whole alignment and cam and caster. I did go ahead and order the right ball joints, should be here Friday.

I don't understand why the toe is so out and why the tire binds on the pavement like 4x4 on sharp turns. Could I have the adjusting sleeves in backwards? pretty sure caster is set wrong, Caster bolts won't move once you set them? so you can tighten them later on?

The upper ball joint is screwed in, not pressed. No other choices. For the lower there is a press in and a screw in. Moog press in is k7025 and screw in is ki727. Easy to identify. The screw in will have 4 flats on it. If somebody tack welded them then they must have been loose. The ball joint stud not being tight is caused by the castle nut not being tightened or the tapered hole was deformed from a loose tapered stud. This website will help for you to see the options are concerning the ball joints: http://http://www.moog-suspension-pa...odge_d150_1989

as to putting the wrong size ball stud ball joint, it should never get so far. When you first open the ball joint package, the FIRST thing you do is trial fit the stud in the knuckle/spindle hole. Not just to make sure it is the right ball joint, but to make sure the female tapered hole it fits into is not damaged or enlarged. Not only is it supposed to fit tight taper to taper, but there is supposed to be a couple of threads below the nut surface (in the hole) to allow for stretch and drawing the tapers together.If you don't the tapers will not lock together properly, you'll probably have trouble achieving proper torque on the nut. If you suspect the female taper isn't correct, you can check the fit with Prussian Blue. I hesitate to advise you can overcome the thread length issue by using a GR8 STUD washer (sometimes supplied with the ball joint) under the nut. This strategy is not a cure all for damaged taper holes, it's only used when the taper is true, but just slightly oversize.

people really need to looks at date on the post. the original post is over 2 years old and the last post in this thread before today is still about 8 months ago.

date doesn't make it any less true. it''s still a thread that can be searched and recalled. it's too late for OP, but it can still help someone now or in the future. Isn't that the point of this forum. "Am I wrong", as Walter Sobchak would say.
