Finaly after one year exploring of the problem,I put a self tapping grease nipple on my torsions pipe.Fill this joint with grease until it blow through the rubber seal.No more SCRACHING.Only the sweet ,,sound,, of silence.I solve the problem with the kind help with pictures and explanations from Rein/Estonia/.For all that have got this problem let me know I will explain what to do.
Regards.Tisho from Bulgaria.
