That is, the components needed to modestly lower a truck are all bolt-on. . These can get tweaked and not stay in place. Jan 20, 2011 u need a ball joint tool. With the hub slid onto the spindle and the outer bearing and washer in place, the spindle nut needs to be tightened no more than 12 lb-ft to ensure that the bearings are seated. Rock the wheel while looking inside at the spindle and kingpin area.
Manufacturers change the torsion bar or key to adjust the ride height, usually to compensate for heavier or lighter engine packages. Shock length: To find the right shock length, the vehicle can be jacked up letting the suspension completely relax hang and then measuring the distance between the shock mounts. If you add a Superlift suspension lift on a 2008 and newer Ranger, then the earlier keys will lift the front more. Some pitman and idler arms use a ball stud and socket as well. Instead it uses upper and lower arms with a coil spring mounted between them. A piece of steel is used to retain the distance, tacked to each tower. These are slipped over the shaft of each shock and rest between the shock body and upper shock tower to mimic proper ride height during the remainder of the build process.
You can check for ways to identify these. Instead, Fatman has designed a lower control arm that straddles the front crossmember for increased stability and packaging. The effective spring rate of the bar is determined by its length, diameter and material. See the section below on how torsion bar suspensions work. The axle centerline corresponds with the center of the crossmember. After this height, it becomes near-impossible to restore good steering geometry.
On kingpin suspension with leaf springs, the spring bushings and shackles are a common wear point. All these axles have a hi-pinion differential, which improves gear strength and puts the drive shaft up higher out of harm's way. If you lower a truck by this method, there will be less suspension travel. Other wear points are the A- or control arm bushings, radius arm bushings Ford twin I-beam , sway bar bushings, track bar bushings, and wheel bearings. Loose spindle bushings will distort the caster and camber readings. This is something to research when shopping for a suspension kit. It is usually possible to improve significantly in this area over what's offered by the lift industry.
Make sure the kingpins and spindles fit properly before checking the beam for straightness. Removal of the coilspring shock still in place can make the process of setting the bumpstop height much easier. The 1 Ford Explorer enthusiast resource on the Internet since 1996. If the edges peen over, just straighten them out with a course file. This is a common wear item. Once the axle centerlines are marked and everything looks good, the front suspension components can be removed.
Your hub for horsepower Get first access to hit shows like Roadkill and Dirt Every Day Join free for 14 days now The use of torsion bars was not widely accepted. When checking the ride height, it is imperative that you roll the truck back and forth 10-20 feet on a level surface to settle the suspension before checking the height. I decided to wait until the crossmember was in place before putting too much heat to the chassis, just in case it decided to twist or get out shape. A U-joint in the center of the axle allows for independent movement of both beams. Ford twin I-beam front suspension uses semi-elliptic leaf springs, just like the 1964 and earlier Ford front suspension designs.
We had the suspension components installed in a day and no sooner had the truck back together up front before we were taking stuff apart out back. New pins and new, ream-fitted bushings should fit together with no perceptible play. Lower rate springs will also have a longer free-length for a given lift height. The stock radius arms are a bit on the short side, but can be easily replaced with extended ones similar in length to the axle beam. Radius rods in wishbone form lend support to the front axle beam and torque tube rear axle. The Dana 35 used from 1998 to the present is a standard rotation Dana 35.
This will open up a ton more tire options for you. The purpose of the front sway bar is to control understeer and body roll by connecting the frame to the lower control arms. Another approach is the fore-and-aft moving pitman arm that moves a drag link. Choices are down to Cooper gone in 40,000 or wears-like-iron Kumho which has only so-so wet and winter traction. This allows me to measure the wheelbase to be sure our plumb bob specs are within factory parameters 131 inches for a longbed. Both were reverse rotation differentials. When a lift is installed or even on many factory delivered vehicles the suspension will often be below this ideal height.
