Bottom Bracket

My bottom bracket is starting to make a nasty noise, particularly when I am climbing out of the saddle and so putting it under a lot of stress.

Also, it's developed a sort of gluey sensation is the best way I can describe it, i.e. it feels a bit like someone has poured glue into the bearings, but only every now and then and for about a 1/4 rotation and only when I am pedalling forward but not when I'm back-pedalling.

Any thoughts anyone, is it just a case of a dab of grease (if so where) or does it need something more significant?

The BB is an Ultegra 6500

Thanks

    if it's a modern square taper or octalink then they are sealed units so will have to be replaced.

    If its old cup-and-cone then you can re-grease and re-adjust

    If it's HT2 cups then yu can replace just the bearings but new units are very cheap anyway.
