    it is also easier to drop the entire subframe as one unit than take it apart.
    I am planning this job in the spring. I like what you did here dropping the entire assembly onto a rolling cart. Any idea of the weight of the entire subframe assembly? This cart looks decent, rated for 660lbs.

      That cart should be fine if the handle folds backwards too, but you'll probably want some way to get a jack under the assy, which may be difficult with that setup. Personally I just put a jack under the diff and let it down until it flops on one side. If you do that you should put some wood down on the floor, and be prepared for a little bending of the backing plates.

        I found that a jack was the best way for me to do it. If you're planning on replacing the brake backing plates (there's likely rust around the e-brake shoe retaining pins), you don't have to worry about bending them. You kind of have to estimate where on the diff to place the jack so the subframe doesn't fall off-- some wood is a good idea to help steady it. Make sure everything is disconnected before it drops! When you re-install using the jack it'll be easier. Off the car, you'll be able to play with positioning and get the whole thing set up nice and straight on the jack saddle for an easy install.

          the cart was just for moving around and working on it. i have a lift, so used a tall trans jack to lower the subframe. subframe assembly probably weights 200lbs. when i didn't have a lift, just used a floor jack or short trans jack. have done a half dozen e30 rear subframe complete rehabs. three in the last year.

            having a way to jack the car up in the back without using the subframe is handy too... note metal lift adapters

              Thinking about putting a lift in my garage prior to doing this job. What lift are you using?

                I have two BendPak lifts. the two post in pic for the working area and a 4 post for car storage in the other bay. zero issues in 5 years. the two post is in use constantly for various maint, resto and race car work.

                if you are thinking about getting a lift....stop thinking. just do it. total game changer. you will wish you had done it sooner. installing a lift should be the first mod done to a car.

                  Cool thanks! Looking at BendPak myself. Trying to figure out if my garage floor is thick enough for a lift. Gonna drill a hole in it this weekend.

                    Drill two holes just to be sure, and use a quality hammer drill unless you want to be there all day.

                      Probably over thinking this but is it difficult to get the subframe on and off the trans jack?
                      Lift is getting installed next week so just thinking through the best way to get the subframe out of and back in the car without having to li on my back!

                        Car to loan out this finely crafted tool you made? I dont weld or I would attempt to make one myself!
