Any special tools required for F22 rear Subframe removal?

The_otherM235i · 05-29-2021, 06:56 PM

Hey everyone,

Just got done putting new Polly mounts in my upper thrust arms, was thinking of doing the rear Diff inserts (not replacement mounts, ECSonly sells solid and I don't want those) as well as subframe bushings and lower control arm bushings.

I have a hoist I can use and some good tools, will I run into anything needing a special bmw tool when dropping it? I looked at the driveshaft snd it's on what looks like a coller and not bolted in, i also plan to do the main upper diff bushing when the subframes down. I don't want to buy any crazy expensive tools to do this job or else I'll just skip it and compensate with some struts braces.

Thanks for your help guys,

Cars a 16 M235XI auto.

Nobody's take subframe out of an F22? Jeez okay.

Yeah, I don't think you're going to find many subframe removers on this forum.

In my case, I'd rather write checks / push plastic than wrench on my fine BMW.

Yeah I hear you, I don't mind getting into the nitty gritty of taking it apart, just wish someone knew if I needed the tool or not, if I do I'm probably not going to do it, don't want to have a $500.00 tool that Id use once, thanks anlot

You're going to need a special tool to remove the axle shafts from the rear differential as well as a less common tool to undo the driveshaft to the rear differential.

You'll probably want a table jack to lower the entire rear subframe.

It's a pretty sizable DIY job. I ended up paying a shop for this because I wouldn't be able to complete it within a day.
