Q: How to remove and install the torsion bar spring with the anchor arm on Toyota Land Cruiser?
A: Initial work to detach a torsion bar spring along with its anchor arm begins by taking off both the front wheel and the engine under cover. Mark corresponding points on the torsion bar spring alongside the anchor arm and torque arm before measuring dimension "A" from the anchor arm adjusting bolt to the frame. These markings and measurement will help installation. First loosen the anchor arm bolt so that you can free the spring tension then take a measurement of bolt "B" for later use. Start installation with the torque arm and its 2 nuts, bolt, then proceed to take off the anchor arm as well as its adjusting seat, swivel, and adjusting bolt. Lastly, remove the torsion bar spring alongside the anchor arm. First install the torque arm with bolt and torque arm and 2 nuts before torquing them up to 225 Nm (2,300 kgf-cm, 166 ft. lbs.). Install the new torsion bar spring while applying MP grease sparingly on the spline followed by anchor arm installation before adding the anchor arm adjusting seat and swivel and bolt ensuring the bolt length reaches the measurement value taken during disassembly. Tighten the anchor arm adjusting bolt until dimension "A" meets its specified value. When reusing the torsion bar spring install the matchmarks on the torsion bar spring to anchor arm first and then on anchor arm to torque arm followed by tightening the anchor arm bolt while aiming for dimension "A" to match previously measured values. Installation of the engine under cover and front wheel should be completed together with torque at 97 ft. lbs (1,340 kgf-cm, 131 Nm) followed by an assessment of vehicle height through adjustment by altering the anchor arm bolt when the suspension is stabilized.
