It's critical to install the grease fitting and to lube this part!!!

There are a lot of negative reviews about Moog and non-OEM, so do your own research.  My 2 new Moog LBJ failed at 18 months/16,000 miles.  What I found is that I had failed to see the horizontal grease fitting hole in the SIDE of the housing (it comes filled with grease from the factory to keep out contaminants so I completely missed it).  So these balljoints basically made it 16,000 miles without a drop of grease due to my poor installation.  I've been a loyal Moog customer for over 25 years, and will continue to purchase their products.  Hopefully I've learned my lesson and realize that when a grease fitting comes with the part that it wasn't a mistake.  I will certainly retract this positive review if there are any problems with these balljoints.  It is my bet that the people that have problems didn't lube the joint properly after installation.  Since Toyota made this LBJ design a high failure item, I wanted to make sure that I bought the best possible part.  I also made sure to fill the joint with a high quality Valvoline synthetic grease.  I'll post back if there's any trouble.

Finally, I bought a grease gun with some quality and durability. This works great. I also bought a Lock n Lube grease fitting which allows you to simply snap the grease coupler over the fitting and it locks in place until you unlock - by far one of the best grease gun accessories in past 100 years.

Do yourself a favor and go ahead and make the purchase.  Odds are if you are looking at this item and review you need to it complete an oil change on some Euro vehicle.  Without other specialty tools in your arsenal this one is required to remove the oil filter on a R52 Mini Cooper S.  buy it and get it done!

Don't forget the Mineral or Vegetable Oil when installing !!!!!

Splice wires High Above Bilge Water Line.

SEAL any splices/solder connections with a Liquid Tape Product.

While basic design/ function are similar to originals....the mounting holes were NOT TAPPED, thus I had to go get my own METRIC THREAD GAUGE, and 8x1.25 TAP, and thread the openings myself. DUH??? Just added a FEW HOURS...to what should be an hour repair!!!?!?
Add the grease...ready to use!!!!

a grease required by GM for a Warranty recall repair , that requires this type of grease! But this was the best price I found !

This is THE MOST AMAZING Fitting / Upgrade to your grease gun. I can't believe I never knew about this years ago. The fitting cost more than the grease gun i use, but it makes the job and zerk fitting removal a breeze. I never get excited, but this coupler makes me excited to use it!!! A+++++ all the way no complaints.

Had to cut threads in the holes but no big deal.  Bolted up, love the grease zerk to lube it in the future.  Make sure you grease it after you put it on-THEY DON'T DO IT AT THE FACTORY AND YOU DON'T WANT TO RUN IT DRY.

I installed a new oil pan and accidentally over-torqued the plug. Doh! No matter what I did, changed back to the factory plug, replaced the gasket, etc., the oil kept leaking. When I did my last oil change, I installed this plug and now my garage floor is oil free. Hooray! :)

I bought this shaft to replace one on my craftsman lawn tractor. My old part contained a sealed bearing at the top of the mandrel housing as well as one at the bottom of the mandrel shaft. This one has an open bearing at the bottom that comes pre-greased. It also has a threaded hole on the top meant for a zerk grease fitting so you can grease it without removing it from the deck. Once greased, the entire mandrel housing will be filled with grease. I just need to add a zerk fitting and should be good to go.

Bought one on each side.  Looks more robust than the OEM link.  The grease fittings were not easy to install, as the thread didn't bite until I forced them get started.  The left-side grease fitting came pre-installed and were of L-shape as opposed to straight fittings on the right-side.  There is no Allen key hole like the ones on the OEM links, but came with hex to grab with a wrench (right-side).  The left-side came with square with its corners tapered, which can be kept from turning with a 17mm open-end.

It seems better than the flimsy-looking OEM link.  Not sure about long-term durability as they are made in Mexico.  However, there don't seem alternatives.

The quality of this item was acceptable to me.  The big problem was that it did not come with the "shown" grease fitting.  I had to install this ball joint and I wanted a grease fitting in it.  I had to drill and tap a hole in it and install a fitting that I had in stock.  All in all everything turned out fine except for the extra labor that I had to eat.

The screw drive on my garage door opener was in bad need of lubrication. This grease worked perfectly. The system got much quieter and smoother the instant I applied the lube. I suggest that you use about half a tube per screw. I used nearly a whole tube which was obviously too much because a dollop of grease dripped on my car a few days later.

Fit is exact.  Very simple to install and the grease certs are awesome to keep lubricated unlike other OEM parts.  Will not be disappointed.

Make sure to have your mechanic pressure test the coolant and oil cooler passages before installation. Mine had a breach in the oil cooler lines that caused fluid mixing. This was a pain to deal with. I should have returned the radiator to the manufacturer to prove the validity of the issue (and subsequent transmission service required), but I returned to Amazon. The manufacturer still worked with me to provide some compensation for the damage caused by fluid mixing.
