For instance, too much grease can increase running temperatures and lead to energy losses. That is because too much grease will cause the components to push the excess lubricant away.

What parts of a car should be greased?

Today's vehicles actually come with a number of parts which are considered to be "lubed for life", which include components such as ball joints, tire rod ends, and U-joints. This just means that not all vehicles need these certain parts to be lubed often, however, chassis lubrication can still be needed or recommended.

Is CV grease the same as bearing grease?

Re: Cv joint grease Vs wheel bearing grease

CV grease usually has Molybdenum Disulphide in it. This in itself is like a solid lubricant. CV's are turning as fast as the wheel bearing, but also have to roll 90deg to that turning direction to adjust for things like bumps and turning.
