Default How do you remove upper ball joints?

Did a search and not much help. Everyone says to drill out the rivets, ok I see 4 huge rivets holding each one on there. I have never drilled out a rivet like this before. I drilled out one side but I can not tell the difference between the rivet and the control arm itself, they look like they're welded together. Am I supposed to drill all the way through???

Another question, is there something I can use other than a hydraulic press to push the bushings and lower ball joints out? No one seems to have one of these in my area.

Default ball joints

I have did my share of ball joints. I have did it with an air hammer or a BFH. This way I have not liked the results due to cosmetic damage that occurs.

With that being said, I prefer to have them pressed out and new pressed back in. Doesnt cost much. Im much happier with the job this way.

Drill or cold chisel on the rivets. Good luck.

for the top ball joints Use a center punch and dimple the middle of the rivet and just drill the rivets out ,its so easy a caveman can do it.The lower ones you should really use a ball joint press to avoid damaging the aluminum control arm.The press looks like a big c-clamp and it has sleeves to press in and out the ball joint,you can either rent on or buy one from harbor freight for about $100 .the same tool can also be also used to replace u-joints.wow i just checked harbor freight and the balljoint press is only $34

I dont have any air tools, but I do have a BFH

I'm trying to drill the rivets but they look like they're part of the control arm. I started off with a small pilot hole and moved up to a larger bit and grounded off most of the head, then used a hammer and a punch to break off the edges. I tried punching out the center of the rivet but it just makes dents. I figured if I kept going I was going to damage the control arm.

When I do these uppers I use a grinder to take off the top (heads of the rivets first. Once the heads are ground off it is very easy to see the shaft of the rivet and then as mentioned above find the center and punch it so you can start a drill bit with little effort. You can use smaller drill bits to make sure you only drill the rivet and not the arm. Once you remove most of the rivit you can use a punch to knock out the rest of the rivet left in the arm. This job goes quicker than you think. Have fun.

You only need to grind the top side off...then drill all the way through...then punch it out with the BFH.

I finished drilling all the way through, got a nice hole now. I tried punching it out but it just dents inward like soft aluminum, not actually getting pushed out. The punch actually got stuck in the rivet and I had to pull it out with the claw of the hammer. The only way I see to do this is to get a larger bit and hope like hell that I dont get into the control arm itself.

There has to be an easier way, took me 2 hours to drill through one rivet and its still not out. I used a 3/8" bit btw.

wow, I feel sorry for you. I changed all 4 balljoints in about 2 hours. Getting the upper control arm bushings changed was a little harder, but nothing a press could not handle.

That doesn't sound right...sure you got the drill in the "forward" direction? You'll need a set quality bits for a jobs such as these...or a drill doctor.

If you grind the heads off and peen a correct exact center of each rivet you can just drill the rivet out starting with smaller then work your way uo to the larger bits until you get the correct hole size....no hammering required this way.

I do not have a shop press, only hand tools. I think the bits i'm using are for wood/drywall, but it doesnt seem to hurt the bit. I guess thats why it takes so long to cut through them. It sucks having all the parts but not the tools to do it with.

I took the lower ball joints to a machine shop. It was like $10 a piece to remove and install them. Which is less than buying your own press. The uppers, I ground the heads off and pounded the rivets out with a punch. You may want to try a little bit of heat on the rivets. That might break them loose. Or, you could take the uppers to the machine shop and see if they'll press them out for you.

To remove the bushings from the control arms, use a piece of threaded rod, use some washers to pack the end you arent pulling out and on the end that you are place a socket with outer diameter same as the bushing. Pack that end with washers start turning nuts at either end and presto home made press for next to nothing.
Play around with it all some and you will realise it has plenty of applications, and its great if you dont have access to a press like me.
Cheers

I tried the homemade press thing but it just broke apart so everything is at the local machine shop, should have everything back some day.
