I tried the right side , removed the nut and rocked it back and forth a d side to side while pulling and it wouldn’t budge. </p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal> The nuts come off easy , a while back both were loose so I tightened them in fear they would come off . I just snug them .</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal> I know the shaft it tapered and splined and think the arm is aluminum . I can’t say penetrating oil will help since from what I see the threaded shaft fits through the wiper arm bore so any oil would have to seep down the threads and maybe reach the spline. </p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal> I have a small puller I can adapt to possibly fit . </p><p class=MsoNormal>Any suggestions?</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal> Just to add I wanted to move the right arm up since according to the Bentley it should be higher. Both arms are the same length and shape from what I can find I think they should be. Also from what I’ve read the blades should be 15” mine are Bosch yet 13 1/2 “ yet this does not present an issue . </p><p class=MsoNormal> Mainly I wanted to adjust the right arm up and also see it I can lube the bushings. If I recall they had a sort of grease that becomes hard . I have read some add a few drops of oil , thought perhaps I might be able to get some grease worked down in there if I can get the arms off. </p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal> They work fine no noise yet I feel they could move a bit faster. I can feel a bit of side to side play in the shafts and a small amount of up/down. What I really don’t want to do is remove the unit and clean the motor of old grease . </p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal> I have a complete 72 unit minus the seals and covers , My 73 was missing the arms when I got it so I used the 72’s . I had most of the dash apart in 85 including the fresh air box I don’t think I removed the wiper assembly I had no reason to. </p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>William</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Sent from <a href="https://go.microsoft.com/fwlink/?LinkId=550986">Mail</a> for Windows 10</p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
