Q: How to service and repair the leaf spring on a wagon on Ford Focus?
A: Start leaf spring maintenance for the wagon by first taking off the rear wheel with its tire and then disconnecting the stabilizer bar from the rear lower arms. The proper transmission jack needs to elevate the rear lower arm 32 mm (1.25 inches) upward. The spring carries excessive tension during springs so users need to demonstrate caution because this level creates potential injury risks. The rear lower arm should be detached from the wheel knuckle followed by lowering the rear lower arm before removing the transmission jack. Another technician should assist in spring removal by extracting the stabilizer bar from the rear lower arm while dragging the rear lower arm downward. The correct installation of the top seat mounting must occur while the spring ends meet both the upper and lower spring seats. The spring installation requires assistance to pull the stabilizer bar from the rear lower arm while lifting the rear lower arm to its position. Use a clockwise rotation to position the spring correctly after ensuring its end meets the rear lower arm spring stop point while visible through the drain hole. Handle the spring with caution because its extremely tense state. At this point avoid using maximum torque with the rear lower arm to wheel knuckle bolt while the transmission jack will secure the rear lower arm into its position. Climb the rear lower arm 32 mm (1.25 inches) while performing wheel knuckle bolt tightening process. Reinstall the rear wheel with its tire before reinstalling the stabilizer bar onto the rear lower arms.
Q: How to Ensure Proper Maintenance of the Leaf Spring on a Ford Excursion?
A: Start the process of servicing or repairing the leaf spring on Super Duty F-250, F-350, Excursion series vehicles by lifting the vehicle and providing support and then taking off the tire wheel assembly. Use a suitable jack under the rear axle to support it before you remove the U-bolt retaining nuts and U-bolts as well as the rear spring upper plate. Start by taking out the nut and bolt from the rear spring front hanger bracket followed by removing the lower nut and bolt from the rear spring shackle bracket in order to detach the rear spring assembly. For F-Super Duty vehicles that have this option you must take away both the auxiliary spring and auxiliary spring spacer after which you can separate the rear spring shackle through nut and bolt removal. The rear spring shackle separation for Excursion vehicles requires removal of its nut and bolt. Follow the removal steps in reverse order when installing the new leaf spring while applying new fasteners with precise torque values according to the specifications because suspension fasteners maintain vital component and system performance. New parts should include either the original part number or an equivalent design which prevents users from choosing substandard alternatives.
Q: How to service and repair the leaf spring on Ford Ranger?
A: The first step for leaf spring service or repairs requires the vehicle to be in NEUTRAL position with the hoist supporting the vehicle. A jack with adequate support power must safely hold the rear axle in position. Install the new lower shock absorber bolt after discarding the old ones and nut and apply torque to 80 Nm (59 ft. lbs.). After discarding the front four rear U-bolt nuts, take away both U-bolts and spring plate before tightening everything to 103 Nm (76 ft. lbs.). Rephrase the spring spacer on rear axle by lowering its position with caution. Use a new bolt and flag nut by installing them into the spring-to-frame bracket and tighten them to 200 Nm (148 ft. lbs.). Replacement of the spring requires removing the spring shackle-to-spring bolt as well as nut before screwing it in with torque set at 103 Nm (76 ft. lbs.). The process starts by removing the spring shackle through the elimination of the shackle-to-frame bracket bolt and flag nut and removing the shackle before reinstallation with a torque of 115 Nm (85 ft. lbs.). The recovery process ends with an opposite operation of removal.
