Did rear wheel bearings too, the two on the sprocket side came out stuck on the spacer but they soon collapsed when I squeezed em up in a vice

Rear wheel bearings look a mess.

There are times when only a large vice and big hammer will do the job wink

Yep all the bearings were dry and rustified, that's the trade off for going through fords I guess, totally drives the grease out, even if it is water repellant grease.

I looked at your pics again this morning Pete. Looks like you changed the lower shock bearing with the knuckle still on the TTR.

How easy (or hard) did you find that? I did it once and struggled no

The real wheel bearing killers are ridged spacers that prevent the seals sitting properly and allowing water in. Yours doesn't look too bad biggrin

Sorry Brian didn't notice your post till now, you could of bumped it if you wanted to.

I did infact change it with the knuckle still in the bike yes as I felt the other ones would go on a bit longer (bugger all movement). The shock one seems to wear out before all the others, the way it is designed the majority of the weight and force must transfer to that particular bearing.

My spacers are a tad ridged but no I don't think they are too bad yet at all. I expect those wheel bearings were in there since new I.e 5000 miles., possibly..

It was a bit of a faff lying on the floor and raising the vice up into place, but not too bad, I found my chunky edged 27mm impact socket I used was possibly a bit too chunky to fit perfectly on the knuckle as i had to place it just right against the recessed part of the knuckle for it to work so defo better to use a non impact one to leave extra space for the old bearing to press through in to. It was definitely quicker than taking the whole thing out though!

I used loads of grease to hold the 17mm socket in place and then tilted the vice up with the 27mm onto the knuckle also. Luckily I managed NOT to bend my small but chunky vice!

You have to make sure the vice you use is wide enough for the tightening handle to stick out the side of the bike past the swingarm because I found its necessary to use a bar extention to tighten it.
