Keep An Eye On Your Ball Joints Polaris Atv Forum
Grease coming out of ball joint boot. Now you want to clean off the zerk to avoid any contaminates following the grease inside. 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. First you should inspect the dust boot for leaks. Ball joints tend to make one large pop or crack on turning when failing however. The uppers are pressed in and can only be replaced by changing the whole arm. You should see bright.
A grease leak is the first symptom that is most commonly associated with a bad or failing cv boot. Also the pressure changes the part goes through in normal driving might force a little out. If the ball joint is capable of being greased use only the grease that is recommended for the job. Okay so i blew threw my boot for the upper ball joint getting my a arm off. Or at least lst time i did it it was that way on my 2000 the lowers are a pain in the ass. If the boot is torn or just plain gone chances are so is the ball joint.
With hands at the 6 oclock and 12 oclock you can try to wobble to wheel. First look to see that the rubber boots holding the grease inside the ball joint are in good shape. The boots should blow up a little. The boot just has a small tear in it i noticed grease coming out of it as i was removing the a arm. There could be a little excess around the ball and spring but still plenty of lube where you need it. If it is torn or possibly even gone then you should at least.
If grease is coming out and they are still flat then it is bad. Id wipe them off and check every couple days. 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. That will test for the ball joint. 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 hoping i could just get a replacement boot but that is not the case. When a cv boot cracks or tears it will usually leak grease onto the inside of the wheel. If it is out of the metal nubby fitting then this a good possibility. If it keeps coming out over the long haul you could have a problem. If it is from the rubber boot it could be because the rubber boots around the joint itself are not seated right this happens.
