I think you are right on about bent wheel,i just had new michelin tire's installed and balanced yesterday,it seemed worse after they got done so i swapped lf and lr tires just to see if if something changed,lo and behold it was so much better,i do think rim is bent on lr now i think i will leave it on the back,thanks for your help,on to rear wheel bearing replacement,hope they are not too bad to do,have a great day.
