The boot just has a small tear in it i noticed grease coming out of it as i was removing the a arm. That will test for the ball joint.
Leaking Cv Boot Grease Passing The Clamp Volkswagen Passat
Grease coming out of ball joint boot. If the ball joint is capable of being greased use only the grease that is recommended for the job. If grease is coming out and they are still flat then it is bad. The boots should blow up a little. You should see bright. With hands at the 6 oclock and 12 oclock you can try to wobble to wheel. When a cv boot cracks or tears it will usually leak grease onto the inside of the wheel.
First look to see that the rubber boots holding the grease inside the ball joint are in good shape. First you should inspect the dust boot for leaks. I was hoping i could just get a replacement boot but that is not the case. Some ball joints come lubricated for life and are therefore incapable of being greased the paradox though is that they dont usually live very long. Pump as much as you can until you see the new stuff come out wipe away dirty stuff carry on smartly. I was going to go and give the zerk fittings a few shots of grease per side but i keep finding conflicting information on just how much grease to put in.
Also the pressure changes the part goes through in normal driving might force a little out. If it is torn or possibly even gone then you should at least. Okay so i blew threw my boot for the upper ball joint getting my a arm off. Now you want to clean off the zerk to avoid any contaminates following the grease inside. If the boot is torn or just plain gone chances are so is the ball joint. If it is out of the metal nubby fitting then this a good possibility.
Next attach the grease gun to the zerk. If it is from the rubber boot it could be because the rubber boots around the joint itself are not seated right this happens. If it keeps coming out over the long haul you could have a problem. Ball joints tend to make one large pop or crack on turning when failing however. A grease leak is the first symptom that is most commonly associated with a bad or failing cv boot. The uppers are pressed in and can only be replaced by changing the whole arm.
Over time with exposure to the elements a cv boot can become dry or brittle and crack or tear. There could be a little excess around the ball and spring but still plenty of lube where you need it. Grease leaking out is abnormal for tie rods but the boots on them still look to be filled with some grease so it could have been excess. Id wipe them off and check every couple days. Or at least lst time i did it it was that way on my 2000 the lowers are a pain in the ass.
