    Ok guys, so along with swapping the engines around in my BMW, I was also looking to upgrade the rear axle and diff to get rid of the 316 Drum Brakes and then replace these with 325 Big Discs and pads.

    The real question at the moment is, will I require to remove the entire rear subframe, or can I get away with taking the diff and driveshafts off?

    Cheers,
    Steve

    If you are going as far as to change the diff and brakes it might be easier to drop the subframe and change the bushes as well.

    Was reading a few bits last night about changing sub frames, but none really give clear indication as to the process to remove it. Even the old Haynes book I've got is s***.



    I'll also hazard a guess that the bushes are OEM replacements only available from Dealers, not PowerFlex ones?

    So does someone have a picture rich DIY guide for this? I`m getting a second subframe (I think they are all the same apart from the EVO one? and I`ll refurbish it wth all new bushings etc and fit this to the car instead of doing the bushes on the original.

    I`ll be doing it in my garage on stands so a good guide would be invaluable. My thoughts would be to refurb be original subframe and then sell this on too.

    Don't get the purple powerflex subframe bushes. The washers that come with them aren't up to the task and warp after just a couple of weeks. Then you need to remove it all and make other crap fit. For me this involved welding some of the washers together and installing longer front subframe bolts.
    You don't really need a diy.
    Get under there and have a look around.
    Remove exhaust to the headers.
    Unplug diff speed sensor, abs, and brake pad wear sensors. move wiring out of the way
    Unbolt driveshaft from the diff. If you do this before you disconnect the handbrake it's a lot easier
    Unbolt handbrake cables from the handbrake
    Remove brake lines
    Unbolt shocks from the top or bottom
    And then the rear subframe should be clear for dropping

    If you need anything further explained i can go into more detail.

    Reinforce the subframe mounting points while your at it.
