yeah i searched "rear subframe" and "all posts" and i came up with nothing on this...

dropping the rear subframe to put in my (insert selfless promotion here) www.driftprovision.com (http://www.driftprovision.com) solid rear subframe bushings...for those of you that put in rear solid subframe bushings or that have dropped the rear subframe, whats entailed in it? do i have to drop the diff with it? etc...and also what did you use to burnout or remove the old bushings...

thanks
alex

The following are two (of many) parts of my 240SX roadrace build project:
Bushing Removal, Part 1 (http://www.mysportscar.com/features/project240/part10.htm)
Bushing Removal, Part 2 (http://www.mysportscar.com/features/project240/part11.htm)

Part 2 also details new bushing installation.

Essentially, I cut as much out as possible with a SawzAll, thn burned the rest out with an oxy-aceylene torch. Then I removed the outer bushing sleeve (see above for details) and sandblasted the whole subframe. Then I pressed the aluminum bushings in and painted the whole thing. Enjoy!

here you go man:

Estavan did a another write up back in the day but I can't find it.

I think you could leave the diff and all the arms on the subframe if you're just gonna burn/cut out the stock bushings but I striped my subframe and pressed the old ones out. Either way sucks

EDIT: haha dam beat me to it

Yeah I'm quick like R. Kelly at a Girl Scout convention.

I couldn't find it either, so I created the aforementioned thread. Maybe Estevan could contribute, for once! http://forums.freshalloy.com/images/graemlins/grin.gif

Yes it does suck. I would take everything off if I did it a second time too. But I sandblasted and painted mine before reassembling it, which would make a major difference in whether or not you chose to take it apart. But honestly the thing is a damned logistical nightmare to start with, and keeping the suspension pieces attached would only make it worse.

I wouldn't burn out the rubber. Instead just drill out the rubber around the center bushings.

Use a wire brush on the end of a drill to remove the portion of rubber next to the sleeve you will cut into.

Or just use a flathead screwdriver and hammer into the rubber next to the sleeve just to have enough space to see where you will be cutting into.

Dissasemble and reassemble a hacksaw blade into the bushing hole.

Slowly and carefully cut the sleeve without cutting into the subframe.

Remove hacksaw.

Use a pair of needlnose visegrips to roll the sleeve inward enough to remove.

Repeat for each bushing.

IMO much better than burning which may warp subframe and although sounds complicated, is really fairly simple.

Not a bad idea. Then you can take your time and make it look nice, like Andy's.
I didn't dissasemble mine. Wasn't really very hard going that route, however, after seeing his, I regret not painting it.

I realized this after I completed the work, but it really isn't a precision piece to start with, so deformation isn't that big of a deal. If mine were deformed, all of them were, because it made it difficult to get the bushings in. But the bushings were aluminum and may have a little shaved off during installation. All in all, not too bad though, especially if you use Estevan's method for getting the bushings in (big bolts, nuts, and lots of big washers, then squeeze them in by turning the nuts.



1) Use a wire brush on the end of a drill to remove the portion of rubber next to the sleeve you will cut into.
2) Or just use a flathead screwdriver and hammer into the rubber next to the sleeve just to have enough space to see where you will be cutting into.
3) Dissasemble and reassemble a hacksaw blade into the bushing hole.
4) Slowly and carefully cut the sleeve without cutting into the subframe.
5) Remove hacksaw.
6) Use a pair of needlnose visegrips to roll the sleeve inward enough to remove.
7) Repeat for each bushing.


This looks good, but would be (IMO) more of a PITA than my method. But it requires fewer off-the-wall tools that most people might not have. I had access to the torch, SawzAll, and cutting wheel, so it made sense for me to do it the way I did.

Alex, I strongly encourage you to read through the two parts I posted above, specifically "Part 2," in which I detail removal of the outer sleeve. This step was the biggest PITA as far as I'm concerned.

Between some slight rusting, oil, road carp, etc., and the discoloration from burning the bushings out, I thought it paramount to blast and recoat it. Relatively speaking, it looks absolutely beautiful.

Having another subframe to do the work on certainly makes things easier and reduces downtime. I would highly recommend going this route. I had no choice because I wanted to ditch all the HICASS crap. Speaking of which, anyone want a HICASS subframe? http://forums.freshalloy.com/images/graemlins/smile.gif
