Installing Zerk Grease Fitting On Lower Ball Joint Testing And Lubrication Hyundai Santa Fe

Nice job Richard, not flaming you here, just some food for thought. The biggest problem withthis method is everytime you drill, there are shavings going into the ball joint and sticking to the grease in there, you can't blow those out, although some may come out, Id say compressed air would just push the other shavings in deeper. When you tap you should of filled up the gaps between the tap teeth with same grease you are injecting into the ball, the gaps between the tap teeth are intended to be filled with grease to catch the shavings and to keep shavings from getting between the tap teeth and you new threads and causing damage to those new threads.

You did flush it, but I would recommend just take off the boot as its a simple thing to do and that way you can super flush out all those shavings that are in there. Keep the boot on, the grease is harder to get out and thus the shavings and the shavings may stick to the side of the boot. with boot off and a 3 flushes or so your ball join will probably be near clean of any shavings.

Just one more thought, although you measured the static clearance of the ball from the top, that changes under dynamic load, how much I sure wouldn't know but physics says it has to. I don't know if the pre made greaseable BJ's are just what you did or fact in some additional bumper room?

Just a thought to improve on your excellent work and instructional video. -D

stiff ball joint is exactly what you want when you buy one, this is an indication that it is good.

this video deserves millions of views it has infinitely valuable knowledge.

[johnjoseph]

each time you use a new drill bit you introduce more shavings into the ball joint unless you use grease but it's advisable to just use one drill bit, but you want to put grease on the drill bit to catch as much shavings as possible

Excellent video, thank you! Just thought if some metal shaving will get inside while drilling and taping?

[timandcarolgreen]

Good video very helpful. I don't know which im more worried about not greasing them or the metal shavings from drilling

[jeffanderson]

A good video covering most things. My worry is there seemed little consideration of the metal chips falling into the top of the ball joint during drilling or tapping.

[richardstone]

If you put a little grease on the drill bit the filings will attach to themselves to the grease preventing them from getting inside the ball joint.
Also, if possible, always buy greaseable ball joints when replacing non-greaseable joints.
Ball joints that are greased on a regular basis rarely wear out.

Thank you very much, Have never used a tap before. Changing out zerk fitting on A arms on UTV . Great job, Very informative.

[deepthang]

I like that you took the ball joint apart. I have ball joints that should not have gone bad so soon and have wondered if there was any grease in them from the start. But. Will the shavings from the drilling and tapping get inside and do any damage? Great video

[carlosperla]

Use a magnet to remove shavings. I also noticed that when you pumped the grease in, it looked exactly as it did when you looked at the original, with the dry spots. Additionally....shouldn't there be a small hole to allow for the replacing of grease? That way you pump in new grease and old grease is squeezed out of the hole. Otherwise, how do you regrease?

Having been in the military responsible as a terrain vehicle driver, the vehicles were equipped with grease nipples for the vehicle to be long term functional.
Earlier days, even consumer vehicles were equipped with these. But I guess that doesn't render any money to spare parts manufacturers.
Good job!
As previously mentioned, the shavings from the drilling and drill bits might be an issue.

Great video. Was thinking of doing this on my ATV. Can't find a good tool to remove/reinstall the ball joints, and they are pretty easily accessible. Watched your video to see how thick those top cups are. I think you may have overfilled them a little bit with grease :). I am thinking a shop vac would have worked well to remove any shavings.

[bobjohnson]

Excellent video, one recommendation I also put a plastic cover over the end of the zerk fitting to protect the fitting. If you do that the zerk fitting will always take grease and will not become plugged over time.

Use a magnet first on the drill bit to magnetize, then close to the hole when drilling and to clean

[miketowers]

very good video thank you just bought complete suspension for my thunderbird no fittings but there will be thanks

[patrickguy]

The drill shavings won't hurt anything...
Rock on, good video, thank you!

[scottyd]

If the ball joint is sealed...
The Overflow grease and pressure,
where does it go?

[joshuaskinner]

How was it putting it back through the control arm. It looks like it would bind easier and cause the boot not to make it through the housing?

[shonuffisthemaster]

good content, thanks for taking the time to explain the process. however i think the video could have easily been 5 minutes long without missing anything.
