Rear bearings a bit graunchy and very squeaky last ride so decided to have a go at changing them myself. Online video from Mr Hope and other guides on t'interweb made it look easy (or so I thought). It's one of the few maintenance jobs I've never attempted myself but with the demise of my most trusted and nearest bike shop I thought it was time to get it sussed myself.
All went well removing the 1st spacers. However I had one hulluva job trying to get the freehub body off. I then noticed the freehub body was cracked. It would wiggle a few mm but in the end I had to give the axle a gentle tap (read big tw*t) from the drive side. In the end the freehub body came off but left the two hub side freehub bearings on the axle. The outer one came off the axle by hand but the other felt like it was welded to the axle.
So far one cracked freehub body, and 2 of the springs just disintegrated as I inspected the damage so far.
I decided to drive the axle through to push the hub bearing out but the remaining freehub bearing was so tight nothing was budging. In the end and in frustration I decided to ditch my soft faced mallet and give it a good tw*t with a metal headed hammer (big mistake). This drifted the hub bearing out but I think I managed to deform the end of the axle I was hitting and the remaining freehub bearing would just not slide of the end of the axle and so I wasn't able to remove the axle from the hub fully.
I completely mangled this bearing until there was just the inner collar of the bearing totally welded to the axle. After much sweat and cussing I drifted it off with a hammer and a flat head screwdriver.
Expensive evening in all. New freehub body 55UKP on Merlin (do I need alloy or steel and does it come with Pawls and Springs?).
I guess I will also need a new axle? I tried just sliding the new freehub bearings in my replacement bearing kit over the end of the drive side of the axle but it's definitely bigger than the inside of the bearing collar!!
The gutting thing is the 2 main hub bearings weren't in bad nick. The only graunchy one was the one free hub bearing. I can only guess it hadn't been drifted in properly last service.
