  • ESP Reset after a front-end alignment

    Got some useful info from our Hunter Alignment Machine guy about ESP and alignments. This applies to all ESP equipped vehicles and not just Jeeps. If you have a alignment and toe adjustments are required and you have ESP the steering angle sensor must be adjusted or unusual ESP operation can result, not always but sometimes you can get unwanted operation. Come Jan 1st 2012 every vehicle sold in the US must have ESP as standard equipment, and all Jeeps have it standard as of 2006.There has been some reports of unwanted operation of ESP that has caused some issues. As of this month every Firestone(nationwide) will have the ability to reset most steering angle sensors, not all but most and the ones that cannot be done must be reset at a dealership as they require there specific scanners. Some vehicles will require the battery to be disconnected for the reset and a "battery saver" cannot be used to save stuff like radio memory or the reset will not work so if your vehicle has a "anti-theft" radio that requires a code to unlock make sure you have that code ready as we will not be responsible for the added cost from a trip to the dealership to unlock the radio as we must reset the steering angle sensor if we are able to do so. They also may deny doing a alignment if they cannot reset the steering angle sensor, even if you have already purchased a lifetime alignment package (you should be refunded the cost).


    You need a front-end alignment after installing upper control arms, front springs or front struts.

  • Whats the difference between the JBA STD and JBA HD Toyota UCAs

    JBA STD Toyota UCAs for the Tacoma, 4Runner & FJ Cruiser VS JBA HD Toyota UCAs for the Tacoma, 4Runner & FJ Cruiser

    First I will start with the STD (standard duty) a-arms, they were designed for the weekend worrier who worked hard all week and wants to play hard on the weekends with his Toyota.  The JBA UCAs will give you 1" extra down travel on the front suspension with more ball joint travel and strut spring clearance.

    The JBA STD A-arm tubing is 5/32" wall and 1" dia. with a Moog style K6292 ball joint. On the JBA HD (heavy duty) A-arms are thicker tubing, with 3/16" wall and 1-5/16" dia with 11ga guests on the bushing bongs. The HD a-arms are for more extreme offroad abuse like offroad racing, rock crawling and dune jumping.

    Both STD & HD will work with the Fox extended travel coilovers and the JBA Coilovers.

    If your steering knuckle is reinforced get the JBA HD a-arms.

    If you jump your Toyota you need the HD a-arms, If your steering knuckle is reinforced with a weld on gusset you need the HD a-arms.

    The Ball joint range of motion
    Up travel is 40 deg off of center line of the ball joint, down travel is 50 deg off of center line. Full range of motion is 90 deg. Note: you will not get that kind of extreme travel with a uni-ball joint


    More spring clearance is
    More suspension travel
    More articulation, See JBA vs Uniball
    More traction on the trails
    More Caster
    JBA UCAs give you MORE for your money!!
