The cruise control is working perfectly except that its constantly making slight adjustments to the throttle position so as to make the car constantly accelerating slightly and then decelerating slightly. Its almost imperceptible, but its enough to drive me crazy. I think I may know the cause of it, but I haven't checked yet. Once I check this possible cause then I'll write about it.

The rear diff itself is ok. Its more that there is lots of freeplay in the rear subframe bushings that hold the rear diff to the chassis. Its just how Subaru made the SVX. The free play allows the diff to rotate some in the axis of the driveshaft when the throttle is pressed, and the bushings are fairly rubbery. Some people with older Imprezas and Legacys also have this problem. The solution is to remove the freeplay by inserting some firm rubber/plastic/urethane spacers into the subframe bushings. Impreza owners have had success with this, and Subafreak has also done this. So, this is just an additional step in the finishing-touches of a 5MT swap. It hasn't been done yet by many people though.

My feeling is that fixing these little glitches make the 5MT much more enjoyable for day-to-day commuting. I'd like to see the 5MT swap instructions updated to include fixes for these minor glitches when solutions are found.
