If I had a reason to replace the bearings, for some of those prices I'd be all over a replace to experiment with!

Hey all,

Thanks to everyone for their assistance here. I ended up sourcing a u-joint of the correct size (EPI Performance Universal Joints WE100290) and had it installed at the local drive line repair shop for $20

I see a few questioning my logic, so maybe I can help here.

My bike has aver 107,000 miles on it now and if I could have simply "lubed" the u-joint I would have never taken it apart, but since there is no grease fitting on the factory u-joints I wanted to make sure that I would not have a failure in the future. Especially after the things I found in the swing-arm.

So, the new u-joint I found does have a fitting for grease and now I am able to lube it and my swing-arm without any disassembly. I only have to remove the cover for the u-joints

Again, thank you for everyone's input

Danny,

More like, Thank You for doing the hunt, and then posting the fix.
I'm one guy who would appreciate having a (Zerk) grease fitting in that little unit.
Otherwise, I consider it to be a time bomb, with an unknown timer.
Now I don't see ever needing a U-Joint, but it's good to have something designed better-than-OEM as an option.
As such, I am slowly accumulating a pile of such parts for the "someday" if/when I may need them.
This item will get added to the pile.
Thanks again.

I've being doing the same over the years gathering a spare swingarm, forks, calipers, fuel pump the list goes on. If only I'd have collected a decent wiring harness as that's the only issue the bike has thrown up and its a right pain in the town halls...

Back in my younger Drag Racing car days I used a Forged U joint that was solid, drilling the holes for a grease fitting weakened the trunnion.

I know a FJR does not had that much torque vs a V8 but I wondered if Yamaha was saving money on a solid joint or it was stronger??

2gen, the thing I learned racing as well is IF you had a u-joint with a zerk you wanted the driving ears to compress the zerk. Vs trying to pull it apart, hard to explain but if you have the parts in hand itís easier to see, proffered to not have one;Ike you but when I do installi make a point to make sure that the driving side is compressing the zerk. Clear as mud right ?

What allows YOU to ride with confidence, without nagging worries, is what's right for you. Most of us who have been around the FJR for 10 or more years wouldn't have that nagging worry.

Thanks for the work you did, and the part#, all info is appreciated.

Could someone explain this: "the driving side is compressing the zerk"? I can't picture what you are referring to, although I understand the principle.

IMHO way overthinking on a u-joint that [generally] turns as slowly as ours does.
