Dust Boots on Tie-rod ball joints

[nyone]

I never pound on the stud when removing a ball joint, unless I am replacing the ball joint. Don't want to distort the threads.
I always whack the side of the joint where the stud goes through, that usually will pop it loose after a few good whacks. I leave the nut on loosely in case I miss and hit the threads.

I do this too but pry the joint appart while hitting. Messed up way to many ball joints hitting the stud/castle nut..and 1 is to many. The other way is way less risky.

You can also buy a specialized puller to put some pressure on the stud when you hit the side. This can be necessary on the occasional stubborn one. The pullers can be obtained inexpensively.

That's exactly what I use. A tie rod/pitman arm "puller" puts pressure on the taper joint and protects the threads as well as the joint at the far end. I still use a light hammer blow if necessary, but often it is not.

Puller kits sure have changed in price. When I had my shop, mechanics always brought thier tools along when they applied for a job - and rarely did any of them have their own pullers. Pullers were expensive "shop tools" and usually not privately owed. The same went for floor jacks, transmission stands...etc.

Now I see complete puller and seal tool sets selling for under $100. Thereis simply no reason not to use them. BTW, noone has mentioned the ball joint "pickle fork". I don't think mine has left the bottom drawer of our roll around tool box in years. Someday some young mechanic will wonder what it was used for.

I only use the pickle fork if the tie rod end is shot and will be thrown away. I didn't know you could buy replacement boots. They weren't available when I was an automotive parts sales rep in the 1980's.

I guess it is possible to damage a ball joint with a pickle fork - but a person would have to work at it. Basically all we are doing with any of the ball joint removal tools is releasing a taper. The taper is then cleaned up and the new ball joint self-centers as it is installed.

In the 1960s, mom used to sew up our replacement ball joint boots out of old glove leather - there are lots of those around any farm. My favorites were the ones that had a zipper in them.

It wouldn't necessarily destroy the ball joint but you wouldn't have any chance of reusing the rubber boot.

Just look at how my reply looks and you will know why I hate computers.

Pickle forks rip boots..in this case it dosnt matter. But they can also damage ball joints. There are reasons why you wouldnt want to use a ball joint press/puller. For instance your not taking the wheel off.

Yep, I'll use a gear puller I have, it has the capability of using 2, 3,or 4 jaws. Spartan motors( bus and MH chassis mfgr.) specifically states to never use a pickle fork on ball joints.

I back up the joint eye with a heavy hammer. a 12# maul works most times depending on space. With that "anvil" in place, the distortion caused by a blow or two from a shop hammer has always been enough to pop the taper. Banging on the threads has never left me with pleasing results. Let the taper pop it's self!

Yes. The trick I learned was to back up the taper joint from the side with a heavy weight or sledge head so it won't move, and then make the joint eye ring with a sharp blow from the other side.....using a single quick smack from a light hard face hammer. The taper was momentarily distorted by "ringing the taper" like a bell. I would often try "ringing the eye" first ....once.... then if that didn't work, go get the puller and put a little lateral force on the ball pin. Then ring it again and chances were the joint would literally jump apart.

I can't imagine a mechanic ever beating directly on threaded surfaces....not twice anyway.

But this sort of trick of how to separate a taper - once a common skill in any mechanical shop - needs to be kept alive, and if a little discussion here helps, it seems worth the effort.
