Good fit for 1991 Accord LX
This is a well made part. was hoping for a USA-made part, but no luck. It comes with all the needed parts for a good installation. Installation of the part requires a press and the various adapters to do the job. Beating it into place is not a good idea. Moog Ball Joint Part No K9643 is the correct part for the 1991 Honda Accord.
Most Liked Negative Review
Maybe good?
They looked heavy duty and good quality out of the box and installed easily, but when I checked them after a week of use, they were leaking grease. These are the sealed units, so no grease should be coming out, and it was coming from what appeared to be a pinhole in the side of both rubber boots, not from the top of the boot where it's designed to allow leakage. I called moog and they said the boots were probably defective, but I don't feel like taking them out and putting another set in. I'll probably only have the car one more year, and the joints should last that long, even with the leak. oh well.

Many of you will buy the cheap ball joint, get frustrated and come back and buy this one in the end. Just buy it now, first thing. Excellent fit and performance.
