Bro I dont understand, do you mean judder or does it jump pass your windscreen?I had similar problem with my E34 wipers, they judder on return. Changed the rubber mounting for the wiper spindle where the wiper arms are mounted.Still no cure, my mech settled the issue. He twisted the wiper arm using an adjustable spanner, place your adjustable spanner securely 5" from the top of the arm and twist your arm once or twice slowly. Check the wiper operation and repeat action until a smooth wipe is achieved.Hope the info is useful.
