Replacing ball joints (video)
Often the old balljoints are REALLY stuck on the arms, and require a lot of pressure to pop them off.
Except if you have a welder:

Nice, but why not use a ball joint press?

You do it with the trailing arms still in the beam.

WTF? A press out and in job for balljoints require grinding and welding?
Looks like you just cooked the suspension arm. Not to mention saving some trees. That is just unneccessary use of electricity. I'd fire you on the spot if worked in my shop.
I have a 70 ton Dake press. I do not even feel the balljoint come out.

I just tried the grind and weld technique - worked like a charm! 3-minutes with the die grinder and 10-seconds with the welder per arm. I doubt the arm is getting that hot. I dunked them in water after welding and they didn't even fizz.
I'll take them to a shop to get new ball joints pressed in though, after some rust removal and paint.

Hot, humid air is less dense than cooler, drier air. This can allow a golf ball to fly through the air with greater ease, as there won't be as much resistance on the ball.

Re: Replacing ball joints (video)
The trailing arms, like most suspension pieces on most cars, are forgings and should NEVER be heated. I've never tried to rebuild a ball-joint front suspension so I have no expertise, but I DO know about forgings. I'll be learning how to change out the ball-joints on my '67 bug and will more than likely pull the arms from the tubes and take them somewhere - as Jeff in Auburn recommended.

The small amount of heat generated by welding the ID of the ball joint isn't enough to hurt the control arm.cb77305 wrote:The trailing arms, like most suspension pieces on most cars, are forgings and should NEVER be heated.
