Right... I've replaced the complete back end of the car which came off a mk4 golf and only done 14,000 miles. Still got to bleed the brakes, may have fecked the master cylinder as I didn't know about not to push the pedal down all the way until after I finished the rear. Anyway this thread is mainly about the 4wd, its on axle stands, started it up, put it in gear but the bloody rear wheels still aren't working. First time I forgot to connect the wiring plug on the back of the diff, plugged it in but still no joy. Am I missing something here??
