 *** However, this Divinol grease still repelled all the grit and sh*t away from itself (and from the king pin bearings) - still keeping the bearings fully and cleanly greased!
 * On the other hand, this Divinol 23980 grease ''might'' not be suitable for use in a CV joint nor in a wheel bearing.
-** This is just a presumption, because it is very thick and very "gooey" - but it might actually be great in  practice.
+** The most important reason against using it in a wheel bearing is because it has relatively low temperature resistance - only up to 110 degrees C.
 *** Being thick and gooey does not mind at all for the king pin bearings (it's actually desirable), as they do not endure high velocity movements, very high temperatures or high torques and do not need precise lubrication viscosity and other lubrication properties (they "just" pivot around the wheel hub assembly with the wheel).
-** Somebody has yet to try this grease in a CV joint and in a wheel bearing and report the long-term effects.

-Grease the new KingPin bearings and insert the top one in the carrier. I find the easiest way to grease the bearings is to put them in a polythene bag with some grease. Then use the bag to squeeze the grease into the bearing, this can be seen in the video. (''picture needed here''). Carefully insert the new bottom bearing and, holding it in place, slide the whole knuckle onto the hub. Fill the Knuckle with 100ml of grease, Suzuki recommend only 100ml and not to overfill. Now the KingPins need to be inserted, but first they need a bead of sealant around the KingPin.
