Rear Subframe Fluid Leak
 

I have a fluid leak coming from the subframe bushing/rubber thing. I believe it is cracked on the inner part towards the rear differential. I've gotten two opinions on it so far, Firestone said it was the bolt going from the subframe into the rear differential.
The other shop I took it to said it was the rubber piece on the subframe and it was leaking hydrolic fluid. I'm sorta leaning towards the second guy because it looks as if it is coming from the subframe. The guy looked up the price for a replacement bushing. But told me they only sold the whole rear subframe as one piece, which he quoted me $700.

Does anyone know the actual name for this part and if there is any place that sells just that part?
Please let me know, my exhaust is painted black with fluids.

P.S- There is a picture of the piece attached.

Thanks in advance,
Alex

I got mine replaced with a solid one made by SPL.

Top one only. The other is the front rear-diff housing bushing.

Hmmmmm, so I'm only going to need the top one?

I replaced mine myself. I bought a solid rear end bushing from one of the guys here. PM rpm06g35 he might have it.
That liquid is just the liquid from the inside of the bushing, it starts to leak when the bushing goes bad.

Yeah just the top one is needed. Give zcar a call and tell him Gabe with the G41 sent you. His prices on the part and labor is not bad at all. Good luck.

Did you notice a difference in ride quality?

No I didn't notice any deterioration in ride quality at all. One thing you will notice, if you do launch your car, is the better traction and improvement on the wheel hop.

i have rpm06g35's solid rear bushing too. no difference in ride quality, shifts are a little more positive and the car launches better

I'm still a little confused about the top pic and the bottom pic. I thought i only needed the rear bushing. I don't know where the bushings in the first pic go.

they go on either side of the pumpkin where it mounts to the car. you can kind of see the edge of one in gabes installed pic by the can on the right

Should I just replace the one thats leaking or do you think i should replace them all while the pumpkin is out? And do they need to be machine pressed or can you just hammer/slide them in?

the solid diff bushing i have has tight tolerances, it sat in dry ice before it was pressed in. i think other companies can be greased and hammered in. also, getting the original bushing was a pain in the ***. it took prybars and a saw to get mine out. i havent run the other bushings and dont know anyone with them so i cant comment. i would guess you would have a pretty tight rear end with all of them

Did they remove your subframe to have it pressed on or did they press it while the subframe was on the car?

pretty much you have to hack the stock bushing out. this is a PITA. putting new one in is a PITA as well. people usually hammer it in but mine was being stubborn and didnt want to go in. i think mine "flowered out" so it was hard to pound in. what i ended up doing was to "pull" the bushing in with bolt and nut

How much for the solid bushing?
