I found your company first on eBay then I bought parts directly from your site. I probably wouldn't have a running car if not for Prime Choice! I couldn't afford everything to fix the suspension from any other place but your prices are so amazing. Thank you,

Rielle Wright

I just wanted to compliment your company on great service, communication, shipping and products. The purchase I made just recently arrived lightning quick. I was surprised because I placed the order almost too late to give you a chance to get it here when I needed it. But the order made it. I also worked with a couple of your folks on an ordering problem and they were very helpful. I will definitely try to call on you again for future orders. Thanks a lot,

Hi. Thank you for your refund, your professionalism and fast response. I am very satisfied. I plan on purchasing new wipers for both my vehicles and will plan on getting them from you. Also if your product is as good as they look I will inform my associates I work with - 250+ of your product. Thank you again and I look forward to dealing with you in the near future. Sincerely,

Paul Horniak

I ordered two sensors for my car. You sent me a confirmation and let me know that it had shipped. I PAID NO SHIPPING. You are the best. I am 59 and I appreciate the way you do business. To be a good customer should I tell everyone about you or just spend lots of money? Danny C. Graybeal

Half the price of anyone else. Very good quality parts and the how-to videos really helped. It took me about an hour to replace both front struts. Thanks and Regards,

Strut Assembly and Brakes. Well you are right - half the price, good quality and excellent service. You were so inexpensive I was suspicious. Everyone told me don't do it - go local. Well they are the loser and I am so thrilled. The job went well and I saved over 500 dollars. Thanks!! I am spreading the word. A Grandmother with guts,

Thanks for the great service! The parts arrived as promised and fit like a glove (also as promised). The instructions that were included made it relatively easy for me to do the work myself. That saved me over $300 on labor. Unfortunately my regular mechanic believes only KYB makes shocks and struts! I would recommend you to anyone and have! Thanks, again! It's been a pleasure doing business with you!

I am glad I found you on the internet. Your parts are so cheap (only in price).Thanks for the good service, fast delivery and free shipping. When I need any parts I will order from you and also tell others about you. (Family members etc.) Thanks,

The Basics of Ball Joints


ball joint

is a device that attaches the steering knuckle to the control arm. There are other parts that use an identical type of fitting but serve other purposes, such as the tie rod end link and certain styles of sway bar end links.


ball joint

is a steel bearing with a stud attached to it, and it is housed in a steel casing. The casing is fixed to the control arm allowing the stud a full range of motion available within the opening of the bearing’s housing. With the housing affixed to the control arm, the steering knuckle enables the wheels to turn left and right and travel up and down with the suspension.

Understanding that there are many different types of

ball joints

is recognizing that all joints are the same but that they use different methods for being bolted to the control arm and the knuckle. Nevertheless, they all use a spherical ball that is housed by a steel cup/housing.


ball joints

are pressed into the control arm, and use a tapered stud that fits into a tapered hole in the steering knuckle. Other

ball joints

are bolted onto the control arm and use a shaft that is inserted into a pinch bolt style steering knuckle. Sometimes the

ball joint

is part of the entire control arm. In this case, the entire control arm must be replaced in the event that the

ball joint

fails. The advantage of doing this is that you are getting new control arm bushings when this new part is installed, however, the part might be more expensive.

The reason for

ball joint

failure is relatively simple to understand. Movement of the

ball joint

creates friction between the metal ball and the metal housing and requires a lubricant to prevent wear of it. This lubricant is a grease and is held in with a little rubber boot. In the event that this boot rips or is torn, the grease can escape the

ball joint

. The grease will eventually be contaminated with dirt and reduce the ability of the grease to properly lubricate. Regular wear and tear on the part will also occur, and just like all auto parts, they won’t last forever and will eventually require replacing.
