and remember always use black CV joint grease in the joint - and dont overfill it.
Good CV joint grease can be bought from a good lube selling place, I usually bought the cofran brand by the bucket - 5 kgs - each joint only uses 90 to 95 grams of grease. for me 5 kg was ok as I used it to pack many cars - you folks can chip in, buy a distribute accordingly amongst yourselves.
It really shows a difference - no rattle, vibration or anything stupid with the CV joints
If your car uses spider/roller joints on the inner (transaxle side) do not use this black grease in it, you need to use regular lithium soap NLGI2 (wheel bearing grease) in it. CV joint grease is only used in lobro type (MB, BMW, VW etc) and rzeppa type (regular axle) type joints
