Easy way to swap rear diff bushing without press?

by the way, my cq is a 90, but it has the cast control arms in front. is that normal?

Yes, my 1990 90Q 20V has cast arms too... the later cars did.

So that would make my car a late model coupe? I haven't bothered checking my vin. Thinking to buy a spare set of control arms and then get new bushings and jus swap them out.

Only the very early coupes had stamped arms.

So that's the one with no airbag right?

I don't know where the breakoff point for that particular thing is... there were a number of things changed on the 1990 cars (ISV/ECU/Control arms/swaybars/airbag) and they all sort of filtered in at different times. As an example my March '90 build 90Q 20V has an airbag, cast arms, and a rear sway bar, but it has the early Hitachi ISV and a two plug (early) ECU.

That's what I did with the rear arms, bought a set of 4KQ arms and cleaned/painted/put 034 bushings in at my leisure. Then I put a 4KQ front sway bar in the rear when I put the rest of the suspension on. I did the same thing with my Miata when I built it, and it gives me a spare set of arms in case "stuff" happens at the track.

Don't forget the fact that your car is 24 years old... a lot of things could have transpired between then and now, like replacement control arms, etc.

this is true, but from what i know i think the passenger side one was replaced, so i guess i only need to do the drivers side, but id rather do things in pairs, you know?

not entirely true. there have been 7-8 coupes that i have either personally owned or have been in my immediate family. there seems to be no rhyme or reason to the control arms these cars had EXCEPT i have never seen a 1990 with cast arms (that had not been converted). i have had several 1991's with stamped which i believe to have been on there from the factory.

1991 US spec cars got airbags. 1990 spec euro cars had them too (at least the 2 i have seen did). i believe but am not 100% sure that all airbag cars got CF driveshafts too.

my car is a 1990 with an airbag, and it has cast control arms. but im unsure if anyone swapped anything over?

its possible.

ill have to ask Steve J in Texas

i would be curious if your car was a euro spec car. does it have a CF driveshaft? the only 1990 that i have seen that is as u described was a euro spec car imported to the usa

My first CQ was a '90, with forged arms, carbon shaft, and an airbag.
If I remember correctly, the VIN ended with 006787.

Kuma · Post by **Kuma** » Fri Oct 12, 2012 5:42 am

I posted my com on the registry, it's at the bottom. I forgot what my vin is though. I'd look it up but I'm on my phone.

Well, people have installed the 034 b3 diff mount in urq's so i would think so.

JonathanL · Post by **JonathanL** » Fri Oct 12, 2012 3:33 pm

If I remember right that delrin piece needs to be frozen/ milled down a hair before you press it.

I saw it break the diff mount pressed in the way it comes outta the box

Kuma · Post by **Kuma** » Fri Oct 12, 2012 3:41 pm

i need a solid answer, yes or no. there is a guy who is selling his from his Urq, and its an 034 mount. I want it if its going to work.

like no modding or anything.

im not trying to mess with extra crap.

Frozen? wait, the Diff mount is a bushing?

JonathanL · Post by **JonathanL** » Fri Oct 12, 2012 3:46 pm

Kuma there's two that look like trans mounts. Those ones bolt on no prob.

The round one on the tail sandwiched in subframe is the one I'm talking about pressing nah mean?

Kuma · Post by **Kuma** » Fri Oct 12, 2012 3:49 pm
