Maybe, I did not spend enough time looking back for this topic, but wish to show some custom made tools and methods I came up with, which should help all who work on their own speedster/550's.
The pictures show the EMPI four/ five wheel hole and flywheel removal device to help hold the flywheel to remove gland nut or on the wheels, remove the axle nut. I show how I removed the weak arm on the EMPI tool and replaced it with 3/8 thick X 3 inch solid steel bar or arm. Since that improvement, it has never broken. On the removal of the axle nut, I use the shown 3/4 impact drive 1-7/16inch or if you can find one, 36mm socket plus 3/4 breaker bar and three foot of chrome moly pipe. That removes most stuck axle nuts and gland nuts. Some gland nuts are 1.5 inches so you might need a larger impact socket. Other shown device is the use of an old VW lug nut and spark plug removal tool which they put in the front trunk and with a 2X2 square piece of steel tubing, cut with notches, and welded on the VW lug nut tool I found this fits inside my AC Delco jack, where the support goes and also fits nicely on the round parts of the bottom of the EMPI coil over shocks. I like using these shocks as they are low cost and give a soft ride, yet can be adjusted up and down, as needed. Just faster than adjusting the torsion bars. The problem I had was the coil spring is strong and I could not compress it one inch, needed to install it on the stock IRS or Swing axle shock lower mounting spots. After too many cut hands, I came up with the cheap device which works perfectly. The floor jack pushes up on the shock and puts it into position and you are not using your fingers or muscles, but letting the jack do the hard work. Once lined up with the bolt hole in either the IRS or swing axle lower mount area, slide the bolt through and this cut my time from one hour total to five minutes on each shock and no hurt hands or injuries. The pictures are not the best, but hope you get the idea. Cheap to fabricate and if you ever install these coil over shocks, this will save you time and your fingers. The next picture is showing how to remove frozen stock brake star wheels. Usually, the screw, inside the star wheel can be removed, but the star wheel is frozen into it's base on the backing plate. Remove the screw using a large screwdriver. Then using a metric 10mm X 1.50 pitch bolt, longer than the adjustment screw you just removed, put that bolt into the threaded hole and use a 17mm socket and ratchet and turn it and I promise you that frozen star wheel will come out with no damage. No using hammer and chisel or curse words. This makes things simple and fast and saves you from injury and also saves the parts. When parts are removed, clean them with a wire brush and reassemble using anti-seize compound. The last item is a flywheel removal and installation device a machinist and welder friend of mine made for me. This is a one off item and nobody sells it. I cannot reproduce it as it would cost too much for the labor involved. But, if you have friends who are good at welding and machine work, this is presented for your review. What is does is remove any VW type one flywheel with more than stock dowel pins or ones with eight tight dowel pins and also, wedge mated crankshafts. Now, we all know removal of any wedge mated type one crankshaft is not easy . And, you don't want to damage parts, so we came up with this proven and tested device. There are two devices. One, for removal of the flywheel from the crankshaft and the other small device installs the flywheel without using a hammer and socket method as Berg suggested. Works great and saves expensive parts. I hope some of this helps you whom do your own work. The repair shops will have some of these tools I showed and perhaps, know about the easy way to remove those star wheels on the brakes. But, you only need a few low cost items and you can make your life easier, when working on your speedster or 550. Please overlook my grammar and the silly T on my computer barely works, so sometimes, it does nothing.
