Feedback from this forum tells me I should have my 2015 26' two axle TT aligned due to excessive wear on the outside of the tires plus have the bearings packed because it is recommended every year. ...
I re-pack grease and replace inner seals myself. Lots of videos on U-Tube. And while the wheel hubs are off, I also inspect my own brake parts as well. Money saved means I can spend dollars on other items. And, it's re-greasing is done properly - not by a young kid working at minimum wage.
