Solid Rear Subframe Bushings/Power Flex Purple Diff Bushing

e92zero · 11-29-2022, 04:01 PM

I didn't see the message above and probably late now but maybe good info for others. The pin in those plastic clips on the trim pieces are removed by pushing it all the way through. You can drive it through with a blunt nail or a small hex key (what I used). good luck.

I just stated this today…have removed the diff already, next is to do the prep to remove the subframe.

Stay tuned…sound like I need to remove the brakes in order to disconnect the brake cable. Can someone confirm this?

Have everything off…

Any tips on disconnecting the brake cable from the hub/carrier?

You have to dislodge the boot on the e-brake handle and depress this this spring.
Then disconnect the cable housing from the backing plate.
Finally disconnect the cable end ferule, and then you can pull the cable free.

Thanks, with some trial and error got it to disconnect yesterday…

Must say, the E9x subframe is a pain (2x heavier) compared to the F8x.

Will refurbish with all new solid bushings and spl links this week…then install next weekend

well thank you ! do u think it can press in the aluminum turner bushings ?

TboneS54 · 09-18-2023, 05:56 PM

It can, but they mention needing to completely drop the subframe to do so versus the easier to pop in poly type. i've seen it mentioned that you DON'T need to fully drop the subframe to press in solid, but I don't know for sure. I've only used this tool once, with poly bushes on an e82 where I only needed to undo suspension and drop the subframe like 6 inches (didn't even disconnect brake/erake lines).

Redd · 09-18-2023, 07:37 PM

I thought I saw somewhere someone was making 2 piece solid bushings now. Forgot where tho...

MaximusB · 11-02-2023, 04:23 PM

Thanks for this. I'm about to tackle this.

Any disadvantage with leaving the diff and axle in place and dropping the subframe with them attached?

Frostynorth · 11-02-2023, 10:00 PM

It's just heavier and more awkward to handle.

MaximusB · 11-04-2023, 02:13 PM

Ahh ok

Also do you or should you use grease on the bushing when pressing them in?

Scrippy · 11-04-2023, 08:41 PM

Just reading this in 2023 and it was pure car porn! I really appreciated the write up as well as the before and after pics. The cleaning is mandatory IMO. Glad it produced that +10mph for ya!

I don’t know if you should, or shouldn’t use lube?
But I’m a gentleman, so I did…

If I were to do it again, I would try it with the diff attached.
