Jimney (JA12, JA22, JB23, JB33, JB43) Caster Bush Pressure Jig The lift-up changes in the caster angle of the wheel, which makes it oversteer and worse straight stability and cornering performance. Corrects caster angle close to normal for improved straight stability and cornering performance. In that case, it can be used to determine the angle of the caster bushing. How to use the shaft is inserted into the two caster bushings and pressed. This product is brand new and unused, but it is an external product, so there may be some scratches on transport. Jigs may be pressed into the press, so please install them by a professional. Caster bushings sold separately. Compatible models: JA12/22JB23/32/33/43.
