Maintenance

Every 3,000-5,000 miles: Grease the ball joint with lithium complex grease fortified with moly, until you see the boots swell (3-4pumps). Grease the arm bushings with the same grease until you see grease pushing out from the EZ Lube ports.

Product faqs

Does your Toyota Tacoma drift from one side of the road to the other after you installed your lift kit?

The JBA upper control arms will fix your problem! No more driving with your hands gripping tightly on the steering wheel to keep your vehicle in the center of the road at 70 miles per hour. Our upper control arms have 3 degrees of built-in caster.

What is more caster?

More caster is the top ball joint moved back toward the cab and the lower ball joint moved forward away from the cab the angle between the two ball joints is the caster. We have moved the upper ball joint back to give the alignment tech the ability to move the lower ball joint forward. So with the lift kit, you get between 3 & 4.5 degrees caster. Giving the vehicle ideal handling offroading and on the highway!

How easy are the JBA arms to maintain on your Tacoma?

The JBA upper control arms have 3 grease fittings on each arm. These grease fittings should be greased every 3000 to 5000 miles or when you change your engine oil. If you take your Tacoma in mud pits or across streams with the vehicle, grease the ball joint after you are done for the day.

What is an EZ lube bushing?

JBA has a patent on our control arm bushings. They have grease ports with a check valve. When you pump grease in the grease builds up pressure and flows all around the ports in the bushing. When the ports are full the excess grease flows out over the check valves on the flange of the bushings. With the JBA EZ Lube bushing, there is no need to loosen the mounting bolts to release the grease pressure. These bushings will save you about 30 minutes of maintenance! The bushings are made of Synthetic Elastomer.

What is synthetic elastomer?

Synthetic Elastomer is a long-chained polymer with many urethane constituents. Over the years the formulation has evolved to yield stronger, yet softer compounds ideal for on and off-road applications. As the compound advanced to yield higher tensile strength, elasticity, and dynamic load capacity, JBA uses the bushing to help aid and tune suspension geometry and they will not squeak like polyurethane bushings.

What grease should I use in the JBA UCAs?

We recommend MOLY EP LITHIUM GREASE. Mobilgrease XHP™ 222 Special grease is an extended service lithium complex greases intended for a wide variety of applications and severe operating conditions. These greases were designed to outperform conventional products by applying cutting-edge, proprietary, lithium complex manufacturing technology. It is formulated to provide excellent high-temperature performance with superb adhesion, structural stability, and resistance to water contamination. This grease has a high level of chemical stability and offers excellent protection against rust and corrosion. This grease features high dropping points and a maximum recommended operating temperature of 140º C (284°F). Mobilgrease XHP 222 Special grease available in NLGI grades 2 or 3 with an ISO VG 220 base oil viscosity. Mobilgrease XHP 222 Special grease is designed for a wide range of applications including the industrial, automotive, construction, and marine sectors. Their performance features make them ideal choices for operating conditions including high temperature, water contamination, shock loading, and extended re-lubrication operations. Mobilgrease XHP 222 Special is an extreme pressure grease fortified with 0.75% molybdenum disulfide that provides protection from wear under conditions pivoting and other conditions that lead to loss of oil film.

What ball joint do we use in the control arms?

We have CNC machines to make our own ball joints out of 4140 steel. The ball joints have 90 degrees range of motion. The ball and socket are protected from the elements with a 100% sealed boot. We Cerakote the outside of the housing to protect it from the elements. There is a grease fitting on the top center of the ball joint we recommend using a grease gun and adding 3 pumps of grease in the ball joint every time you change your oil. If you drive through creaks and in mud pits, we would recommend greasing the ball joint after you are done.

Why don't we use the uni-ball joint?

The Uni-Ball was designed for offroad racing applications, these vehicles are disassembled and they replace worn parts on the vehicle after every race. In other words, the Uni-Ball is not designed for the everyday weekend warrior who uses their vehicle for regular transportation more than they go off-road. The open design of the Uni-Ball allows dust, dirt, salt, and other debris to enter the component and wear it out prematurely. The JBA Ball Joint, on the other hand, has a sealed construction that keeps debris and the elements out, extending the life of the joint and allowing you to use it in your daily driven vehicle. The uni-ball only has 33 degrees range of motion vs the JBA ball joint with 90 degrees.
