Differential Mount Bushing Removal
 
Anyone know a good technique? The rubber is easy enough to get out, but the steel ring pressed into the aluminum is a PIA.

got mine out with a body shop type air chisel hammer fitted with a point chisel, took a while to dig them out

you can also take a hacksaw or cutting wheel and cut the steel flange straight across even with the ID on opposing sides to remove those flange segments. This then gives you a surface on the aluminum bracket to set against and push them out with with a press and suitable diameter rod, bar, or pipe (or large socket)

several places that sell them already installed in the support bracket too, think RX8Performance does

if you think that's fun wait for the day when you decide to do the rear subframe bushings, lol

?..OE Alloy Diff Mount Bracket comes with rubber bush and steel ring each end as one unit only...not cheap at a few hundred bucks though.

My OEM ones are probably fine, but wheel hop on hard launches remains a problem. I want to up the stiffness, but not impact NVH too much. Hence, I'm trying a set o bushings produced by your countrymen.

Got mine out by cutting rubber out with a knife then cut through the steel wall of the bush with a hacksaw being careful not to cut the Al wall . once the steel ring was weakened i was able to push the bush out fairly easily.

HiFlite999 01-20-2013 12:32 PM

^ That's what I've been trying; progress is slow.

BTW, does the differential have to be dropped completely out of the car in order to swap mounts?

Brettus 01-20-2013 01:02 PM

No , I got mine out just by rotating the diff around . Swearing a lot helped BTW .

Think I made two cuts opposite each other, to get the steel bush out , from memory .

good thing I don't have to deal with this ... at least for now.

But one day ... oh man i feel the pain when I thought about it ...

No worries M8..;)

Just for interest, the Series 2 Diff Mount Bracket (also includes rubber bushings) is 'heavier duty' when directly compared to all S1.

Also the NC Miata/MX-5 is heavier again in the 4 hole aluminum 'bracket area', side by side I cant see why the Miata would not fit, having said that the MX-5 bracket takes a lighter (weight LSD) Differential...

Please let me know if you are having any shipping issues with this local (AU) supplier..

so is it possible to swap the S2 dif mount bracket into S1?

I think u talked about it before, i just don't remember :(

dannobre 01-20-2013 10:13 PM

The S2 is a different part # model code to S1, but it mounts in the same Rear X Member/Brace, Diff Housings studs are the same, except from a few minor part number updates, so yes M8, the S2 should fit no problems..

Seeing it has the same dimensions "installation wise" to the NC MX-5 (unchanged) I don't see why not, sorry I don't have a S1 Diff Hanger in my possession, but I have an S2 and a NC.

Can anyone else confirm from experience that the S1 diff housing / mount will bolt up to the S2 diff?
