Had a bit of a read last night and am now back from the car spares shop (again). I bought some CV joint grease which is Moly and Lithium padded. Why buy grease with one added metal when you can have a grease with two? £5.14 for 500g.
I recently changed a twenty year old half shaft and cv joint, and was actually surprised at how 'wet' the grease still was by comparison with all the hundreds of old bearings I've played with in the past.
This is the fourth tub of grease on my bench so I'm hoping that they're like tools. He who dies with most etc.. Naturally, one of the others is copper grease, as suggested by cockney steve but I didn't read his post until I got home.
Thanks to all of you, my reversers and speedbrake will now keep me out of trouble for many years.
