    2016 Aluminum. To be honest I have given up for now replacing bearings and just regreased them. Shame as thought would be easy. Probably should have bought proper Giant bearing tool or a compact one. It was the lower shock mount bearings were tricky and put me right off. Tool I got too big and will have to get some washers to fit right through other hole to get tool to work. Cheers.

    My Anthem is the same maestro suspension ashetrance and I did it without any special tools. From memory the pivot bearings went notchy on mine because they don't do a full rotation.

    Thanks for vids. Really do want to change them and will have a go again. Although one of the seat stay pivots bolts rounded out which was even more frustrating, so dont know how will get that out. Was using decent allen bit. Probably have to leave it. Cheers.

    Sometimes imperial allen keys can help or you can get sets that go up in .5mm increments. Sometimes it helps to use a new allen key if struggling to undo tight screws. Another way is to tighten up slightly before trying to undo them. You can also carefully drill it out. Don't forget wd40 can help as well.

    On my old Trance X, yes you had to take those axles/pivots out to replace the bearings. Some of them were a very tight fit and required a mallet to get them out but I usually managed it.
    Try sticking the whole thing in the freezer overnight to see if that loosens it - the bearing is steel and the pivot is aluminium.

    I've cracked one of the retaining bolts in the past too when it was so stuck it wouldn't come out. I ended up buying a new set of pivots which come with new bolts.

    Yes, that axle should come out.
    I changed the bearings on my 2016 Trance 2 a while ago and using the Giant bearing puller kit made it a doddle.
    I made a list of all the bearings needed so here it is it is helps you:

    Rocker/Seat stay: 6900VRS with lip (2 off)
    Rocker/Seat tube: 6900VRS (2 off)
    Rocker/Shock top: 698VRS (2 off)
    Lower pivot/Chain stay: 6902VRS (2 off)
    Lower pivot/Shock bottom: 6802VRS (2 off)
    Shock bottom/Frame: 6802VRS (2 off)

    I bought a set of replacement bearings from Kinetic Bearings.

    Well I was having great success in changing the bearings as figured out how to do. It then came to this small one and the outer race stayed in the frame! Going to have to get a Dremel tool and cut out as delicate as possible...........time for a new bike think lol!! Anyone cut out a bearing and know if can get a Dremel disc that small? Will try this but might have to buy new pivot arm. Cheers.

    When i had a similar issue on my Anthem i found a socket that was just the right size to pick up on the bearing outer without touching the frame and knocked it out with that whilst supporting the pivot arm on some wood till it was flush. I also drowned it in wd40. Another way is a sharp edged pin punch and knock the edge of the outer bearing and keep swapping positions so it comes out square. The dremel method doable if you have the right cutting discs, not all will do hardened bearing steel though. You should need to only slit it once to get things moving.
