don't split the ball joint; it never goes well unless you have the nice handy porsche tool. remove the bolt that holds the control arm to the subframe (you loosened this earlier). that should give you enough play. i don't think you'll need to remove the diagonal link, but i've been wrong before....

you have a better view there; if you think the diagonal link is a problem, remove the bolt in the center of the control arm BEFORE you separate the control arm from the subframe. once you have enough room, use a c-clamp to pinch the upright to the strut (put the c-clamp where the drop link goes). i think you'll get better leverage w/ the SIR tool if the wheel carrier is still attached to the strut.

I think it's the diagonal that is limiting the downward movement at this point.
Remove the bolt next to the nickel in the pictures you took. Then slide the diagonal fork out of the way.

to answer your questions
#1 yes, removing the strut bolts at the top along with the diagonal brace will allow the strut to drop down, then you can swing it out from under the fender and pull the strut out of the carrier. I was replacing the struts at the same time, so this is what I did.
#2 I also just removed the ball joint bolt and pulled the carrier off the car. I had previously done the rear ball joints with the carrier on the car. After wrestling with that I had decided I wanted to do the fronts on my work bench.

At some point you will need to get the ball joint removal tool if you plan to continue to work on the car. The tool I use is KD 3916. I found mine at NAPA, but a quick online search shows that SEARS has it now for $20.

Actually, when the most recent pics were taken, I had already removed the bolt that holds the control arm to the subframe. (Just loosening it really didn't seem to do much.)

On control arm terminology I sometimes get a little screwed up, so I guess I'll go with what Bentley says: "transverse" being the one that is perpendicular to the long axis of the car, ie the one with the ball joint at the bottom of the wheel carrier. "Diagonal" is the other, the one that bolts onto the center of the transverse.

I think you're right, Tom, I think it is the diagonal portion of the control arm that is holding things up. You both recommended I remove the bolt that holds the two parts together (ie "next to the nickel") and that makes sense to me. Insite, you recommended I do that BEFORE I separate the control arm from the subframe. I assume you mean before I remove the bolt holding the transverse control arm (not the diagonal) to the subframe, right? If so, as I indicated above, it's too late for that.

What's the problem that you run into doing it after instead of before? Is it just tougher to wrestle the two arms apart from each other? I could probably put the jack under the inner end (where the bolt has already come out) and lift it back up to approximately where it was.

If you're reading between the lines here you may have already accurately concluded I got NOTHING done on this today, other than reading your suggestions. It was a really tough, really long day at work---I got home just too bushed to even think about working in the garage. The fact that it was like 90 out didn't help matters...

Okay, if anybody's still keeping track of this, my progress:



Got the hub pushed out, breaking up the bearing in the process. Doesn't look too bad, but I haven't looked too closely yet. (Hopefully it IS the source of my noise!)



As another member here (JFP) once remarked, by the time you get to the point where you can use the SIR, you're a connection or two away from having the whole wheel bearing carrier off...at which point, you could remove it and take it to a machine shop to do the pressings. However, like I said before, I wanted to be able to do everything in my very own garage. So far, the SIR is working like a charm. It's so agreeable to be able to use a tool that does exactly what it's designed to do, with not a lot of effort, without having to jury-rig anything.

I ended up uncoupling the bolts of the control arms (diagonal and transverse). (I figured out why Insite recommended loosening the bolt that holds the two together, at the middle of the transverse BEFORE removing the bolt that holds the transverse to the subframe: Once the subframe bolt is removed, you can no longer crank on the bolt in the middle (and it's on pretty tight), because the whole thing moves around too much. Are those (the ends of both parts of the control arm) going to be a bear to get back into place in the subframe?? Guess I'll find out...

I've noticed in some of the DIY write-ups recommendations against reusing some of the bolts in reassembling certain suspension components. By kid calls BS, but I was curious what some people here thought. For those of you who have taken apart suspension, brake calipers, etc, have you re-used all the nuts and bolts? If not, which specific ones should one use new ones on? Wouldn't slapping a little Loctite on accomplish the desired result?

Who's used the SIR tool?

For anyone who's used the SIR tool (or anyone who just happens to know), is this the correct set-up for pushing the bearing out? That's a 14" breaker bar and I'm pretty much putting my whole weight (175 lb) on it to get it to turn even a little. Should it be that tough?

Looks right.......



Assuming you have lubed the theaded sections of the tool, it should require some effort to get it started, then release and come out. Normally, I would use an impact wrench to get it moving.
