A couple years ago I slid while making a turn and my passenger side rear wheel hit a curb. It probably wouldn't have normally been so bad but I think the fact that I had 17" rims back then gave it enough leverage to cause major damage. Basically what happened is the rear lower control arm pushed against the frame where it mounts and bent it in pretty bad(I believe the part that got bent is called the lower control arm bridge).

I ended up straightening it out pretty well using a come-along and I reattached the side that got bent to the car using 4 bolts and a bunch of sheet metal screws. It has held up since then and the wheel is almost completely straight but I would like to fix it the proper way by replacing the control arm bridge. I figure I can go to the junk yard and remove one from a civic by simply drilling out the spot welds and then just attach it to my car by welding around those holes. I just wanted to ask if anyone has ever had this problem and if so can you supply me with before and after pics or any other information? Thanks.

 

Can you post pictures?

 

Are you talking about this part? I mean the black part, not the F7 brace attached to it.

 

I managed to find it in the OEM schematic, assuming that's the part you're talking about.



50200-S04-A02 001 001 BEAM, RR. 589.58 412.71

It should (assuming I'm looking at the schematic correctly) be held in by 12 bolts. The image shows it in the front, but it's listed under Civic - [year] - [trim] - [engine/transmission] - REAR BEAM

 

^ That's the front subframe. Honda calls it the rear beam for whatever reason, presumably because it's behind the engine.

 

^^ Rear subframes are spot welded on, not bolted....

There are quite a few of them too.

 

Well ****, I tried

Is the first image I posted the rear, or is that still the front rear?

 

Rear. And it's attached with a hell of a lot of spot welds. I don't know why these weren't a bolt on item.

 

Assuming it's for an EG sedan it's number 35 in this diagram. Part number 65750-ST7-A00ZZ CROSSMEMBER, RR. FLOOR can be purchased new from Majestic Honda for $136.82 (which honestly isn't that bad when you figure in how much work is involved with drilling all the spot welds out of a junkyard crossmember)

 

88 spot welds holding the subframe on, if I'm not mistaken.

 

As 94EG8 said, it's the #35 part on that diagram. I'll post some pictures by the weekend, I'm out of town at the moment. $136.82 really isn't bad for a brand new one. Has anyone here ever seen that part get bent before? Do I just have to drill out the spot welds, remove the part, line up the new part as best as I can and just weld around the holes?

 

Mine is bent from the PO. But not enough to affect my alignment. It's the main reason I got the ASR subframe brace.

 

Yea, I thought about getting a lower tie bar just as a precaution to help brace it and then I could just get an adjustable rear camber kit to get the wheel completely straight. Might do that if I'm not able to install the part myself and a body shop wants too much. Do you have any pictures of yours?

 

 

Here's the pics I said I would post. These are all pics of its present condition. I have 4 bolts and some sheet metal screws holding the passenger side part of it in place, as you can see. When the accident first happened that whole passenger side broke away from the frame and had about a 2 inch gap between the part and the frame. I managed to get it back in place using a come-along and I tried to straighten out the bends as best as I could with a sledge hammer. It is pretty straight but I don't trust its structural integrity.
