One concern about greasing ball joints is not wanting to overfill it and bust the seal between the ball joint and the dust boot, which leaves the joint open to contaminates that can potentially lead to failure.

How much grease do ball joints take?
The correct lubricant must also be used for the maintenance of such joints, which means that at least 1-2 tablespoons of grease per day are used per joint. Wipe the top of the cloth with a piece of cloth so you can see the shiny metal before you set up the grease gun for installation.
How do you know when a grease fitting is full?
If this is the case, the best tactic is to “feel” the grease into the bearing cavity until slight resistance or back pressure is felt against the trigger, or lever, signaling the bearing cavity is now full.
Can you over grease a grease fitting?
Grease guns are capable of producing as much as 15,000 psi. Therefore, the seal can burst, permitting contaminates to get into a bearing’s housing. Excess pressure and over-lubrication simply make it easy for any crusty-build-up to break away and cause damage.
Do I have to grease new ball joints?
You have to grease it yourself. It came with the grease fitting that you have to screw it into the ball joint, then plug the grease gun to it to pump the grease into the ball joint.Some grease, but you should always add grease if possible to ensure proper operation/longevity.
Should ball joints leak grease?
Ball joints used on most modern vehicles have grease sealed inside them (some require that grease be added periodically). The seals can leak with age, and once the grease leaks out, that will accelerate wear and eventually cause failure in an old ball joint.

Which is better sealed or Greasable ball joints?
Bottom line on strength: The non-greaseable joint is slightly stronger than a greaseable joint. The exact number, how much stronger, is unknown and we do not believe it to be very significant. Bottom line on wear life: A regularly greased greaseable joint will outlive a non-greaseable joint.
How long do ball joints last?
While ball joints may last 70,000 miles or more, they don’t last forever. Their actual lifespan will depend on your driving habits, road conditions and exposure to road splash and salt.
Can you over grease a bearing?
Too much grease volume (overgreasing) in a bearing cavity will cause the rotating bearing elements to begin churning the grease, pushing it out of the way, resulting in energy loss and rising temperatures.
How much grease should you put in a grease fitting?
Rule of Thumb #2: One Stroke per Inch of Shaft
Different grease guns deliver different volumes of grease per stroke. It would probably be better to say 2 or 3 grams per inch of shaft diameter.
Why does my grease gun get stuck on the fitting?
Grease guns get stuck on fittings due to clogged zerk fittings which don’t let the grease pass through and cause a pressure build up that prevents them from releasing. So to get it unstuck unscrews the hose or hardline from the gun which will release the pressure and allow it to come off.
How much grease should you put in a bearing?
Open angular contact thrust ball bearings for screw drives should be lubricated with a grease quantity that fills ~ 25 to 35% of the free space in the bearing. Freshly greased bearings should be operated at low speeds during the running-in period.
How often should I grease a bearing?
Using the chart and the formula, the bearing only needs 8 grams of grease every 10,000 hours. If your grease gun delivers around 1.35 grams per stroke, that means the bearing needs 6 strokes every 13 months; you could average it out to a stroke every 8 weeks or so.
How do you remove excess grease from bearings?
For bearings equipped with fitting and drain:
Pump grease into the fitting until old grease is purged and new grease appears. While the drain plug is removed, allow the machine to run at operating temperature. This will allow the grease to expand and force excess grease out of the machine, relieving internal pressure.
What causes loose ball joints?
Dirt, grime, oil, salt, and anything else on the road can make its way into the ball joint and lead to a loss of lubrication. Ball joints can also rust and deteriorate, which will cause unintended movement and looseness.
How often should you change your ball joints?
Generally speaking, you should expect to have to have your ball joints replaced between 70,000 to 150,000 miles of driving. Excessive play in the joint can cause additional wear, and if a ball joint fails, your car’s suspension could collapse and you could lose control of the vehicle.
Can ball joints break?
Ball joint failure isn’t a common problem, but can be the result of years of driving along bumpy, uneven road surfaces. A broken ball joint may be the cause of a mysterious clunking noise or drifting steering. And once they’re worn, they will seriously affect your steering and suspension.
What is the best grease to use on ball joints?

Do outer tie rod ends come greased?
Some outer tie rods come with a grease fitting, which often come pre-greased and do not require any additional grease added when installed. However, make sure the grease fitting bolt is tightened during installation.
Do MOOG parts come greased?
These heavy use and severe conditions increase the likelihood of contamination that can cause premature wear. While MOOG greaseable parts come greased from the factory, they should also be greased at the time of installation to fill the dust boot and lubricate the interface between the boot and mating part.
