  Before starting work on the Jounce (W/O JL4) brace hose it is essential to elevate the vehicle and remove contaminants from the brake components. Put rubber caps on brake pipe ends to stop brake fluid leaks and poisons when the pipe ends show. Put a maintenance tool on the hose end to remove the brake pipe fitting from the hose before you secure the exposed pipe end. tinh the jounce hose by first removing the brake hose retaining clip from its bracket position and taking the hose free from its mounting point. Detach the 2 brake pipes from the junction block at the rear axle hub and seal the open brake pipe fits using caps or plugs. Take out the brake hose from the vehicle by first removing the bolt from the axle junction block. Second step is to put the junction block retaining bolt at the axle and tighten it to 12 N.m (106 lb in). Secure your connection of rear brake pipes into the junction block on the axle using a torque wrench to 25 N.m (18 lb ft). Keep the hose straight and away from suspension parts during assembly. Before braking apply the 1Jounce hose into its bracket and lock it with the jounce hose retaining clip. Insert a back up wrench into the brake pipe fitting T end to connect it with the brake hose while taking care not to bend the bracket or pipe and tightening the connection to 25 N.m (18 lb ft). Check if the hose touches any suspension part during installation; take action to fix this issue if it does contact. Close the hydraulic brake system and let the vehicle reach ground level.
