Rattle in the rear shock

Hi, i took my specialized enduro into the shop am waiting for a verdict for their opinion on what is causing this. It occurs where the top of the shock connects to the main triangle. I am thinking that it is perhaps a bearing but am looking for an opinion from someone who knows about the connections between a shock and the frame (i honestly dont even know if bearings are placed in that hole).

Any thoughts or help would be appreciated.

It's likely the bearing is worn or perhaps the fastener needs tightening. One way I tell (on my Fisher Cake full suspension) is to pickup the frame slightly, and try to detect play in the bearing by listening or feeling a slight "click". The "click" is the point where the bearing contacts the pin. (Hard to explain). I'm not sure what kind of bearings you have (roller, ball, journal), but it shouldn't cost much to replace/service.

As a "lesson learned", my friend bough a set of cartridge bearings from Giant to overhaul the bike. The set cost ~$80 for eight bearings. I inspected the bearings and from the coding/inner diam/outer diam/seal type and width, I determined I could get an equivalent set of industrial bearings for something like $20 from McMaster-Carr.

Yes, it makes a clicking sound and is similar to a loose headtube when the bike is pushed forward and back. I have it at the shop right now and will recieve the "verdict" tomorrow, i was more just curious how bad its was going to hurt as a far as cash and whether it is a major problem.

It is just wear of the shock end bushing and the alloy adaptors. It is not an exspensive repair.

McMaster does not sell all of the washers, bushings and spacers that come in that kit.
