Can someone tell me what I highlighted in paint? the blue and red lines. Which one is the bushing? Can someone tell me if that crack that I pointed out is bad?

Thanks

 

Its a trailing arm bushing...the whole thing comes as 1 unit. You can buy a replacement set of mugen mounts at king motorsports for $115.
Do not get those urethane ones, if youre replacing.

Search for trailing arm bushing and you will come across how to remove and install new ones yourself w/o a press.

 

both of them make up the bushing? I'm really broke (-$200) so i was wondering if I could just put that in there or is that crack in the bushing going to destory me. I bought that arm b/c mine was bent bad.

 

it depends on how bad the crack is, but from what I see, I wouldnt put it on there.
Try some window weld globbed on to seal it up as a temp fix.
