It is not necessary in most cases to remove the rear wheels. However, in some applications it may be easier to access the area where the assembly must fit by removing them. If you do remove the wheels, lift the rear axle and support it with jackstands before removal.
Three main preparation steps are required: (1) If a ground strap bolt protrudes from the frame just behind the axle on the passenger's (right) side, trim it flush to the frame with a hacksaw or grinding wheel, or relocate it by drilling a smaller hole away from the mounting area and re-attaching the strap. (2) Remove and discard the heat shield covering the passenger's (right) shock and the strap on the outside of the frame. (3) On the driver's (left) side frame rail just ahead of the axle, remove the nut from the wiring/fuel/line holder, pull it out, install the small spacer shim (M) into the stud, and reinstall the holder with the stock nut, tightening securely.
Assembly steps: (1) Set roll plates (C) on top of air springs (D) and install fittings (E) finger-tight into the top of the air spring, then tighten the fitting an additional 1.5 turns. The fitting should be opposite the flange. (2) Set upper brackets (B) onto the top of the air spring assemblies and attach with 3/8 inch hex cap screws (F), 3/8 inch lock washers (G), and 3/8 inch flat washers (H), leaving loose. (3) Flip the assemblies over and set a roll plate (C) and lower bracket (A) onto the bottom, making sure the flanges on the upper and lower brackets are on the same side. Attach the lower bracket with the same hardware, leaving loose. (4) The assemblies can be used for installation on either side.
Set the air spring assemblies on the leaf springs over the axle and push them back on the leaf springs as far back as possible so that the lower brackets come in contact with the front of the leaf spring assembly upper spring retainers. Attach the lower bracket to the leaf spring with U-bolts (I), 3/8 inch flat washers (H), and 3/8 inch nylon lock nuts (K). Torque to 16 lb.-ft. (22 Nm).
Yes, drilling is required. Before drilling, check the back side of the frame for clearance issues with brake lines, gas lines and electrical wiring harness, and temporarily relocate any obstacles. Use the tallest span holes in the front flange leg and the two lowest mounting holes in the rear flange leg of the upper bracket. Center punch and drill a 3/8 inch hole through one of the flange mounting holes, install hardware, and tighten just enough to hold the bracket in place. Drill the remaining three holes, then install all hardware and torque to 44 lb.-ft. (60 Nm). Repeat on the other side.
Yes. After the air spring assemblies are fully installed and aligned, trim the inside U-bolts above the nylon lock nut with a hacksaw or a grinder with a cut-off wheel.
Yes, you must drill a 5/16 inch (8 mm) hole for each Schrader valve location. Choose locations for the valves (such as inside the fuel tank filler door, inside rear wheel wells, or license plate/rear bumper area) and drill as needed.
Torque the U-bolts (I), 3/8 inch flat washers (H), and 3/8 inch nylon lock nuts (K) to 16 lb.-ft. (22 Nm).
Torque the upper bracket frame mounting hardware (3/8 inch hex flange bolts with 3/8 inch flat washers and 3/8 inch nylon lock nuts) to 44 lb.-ft. (60 Nm).
Torque the air spring mounting hardware (3/8 inch hex cap screws, lock washers and flat washers connecting the air spring to the upper and lower brackets) to no more than 20 lb.-ft. (27 Nm).
Make clean, square cuts with a razor blade or hose cutter when cutting the air line; do not use scissors or wire cutters. Use zip ties to secure the air line to fixed points along the chassis. Do not pinch or kink the air line. Leave at least 2 inches (51 mm) of slack in the air line to allow for any movement that might pull on the line. The minimum bend radius for the air line is 1 inch (25 mm). Keep at least 6 inches (152 mm) of clearance between all air lines and the exhaust system, and avoid sharp bends and edges.
Schrader valve locations include: (A) inside the fuel tank filler door, (B) inside rear wheel wells, or (C) license plate or rear bumper area. Choose the location that works best for your vehicle and drill a 5/16 inch (8 mm) hole as needed.
The minimum recommended air pressure is 5 PSI (0.34 BAR) and the maximum air pressure is 100 PSI (7 BAR). Always maintain normal ride height and never inflate beyond 100 PSI. The actual air pressure needed depends on load and gross vehicle weight rating.
Wear safety glasses during installation. Before drilling the upper bracket mounting holes, check the back side of the frame for clearance issues with brake lines, gas lines and electrical wiring harness, and temporarily relocate any obstacles. Keep at least 6 inches (152 mm) of clearance between all air lines and the exhaust system. Do not exceed the vehicle's maximum gross vehicle weight rating (GVWR) or payload rating. Do not exceed maximum inflation pressure of 100 PSI (7 BAR).
Perform the following checks: (1) Clearance test — Inflate the air springs to 40-60 PSI (2.8-4.1 BAR) and ensure at least 0.5 inch (13 mm) clearance from anything that might rub, including the tire, brakes, frame, shock absorbers and brake cables. (2) Leak test — Inflate to 40-60 PSI and check all connections for leaks; all leaks must be eliminated before road testing. (3) Heat test — Ensure at least 6 inches (152 mm) clearance from heat sources; install any included heat shield. (4) Fastener test — After 500 miles (800 km), recheck all bolts for proper torque. (5) Road test — Drive the vehicle 10 miles (16 km) and recheck for clearance, loose fasteners and air leaks.
Check air pressure weekly. Always maintain normal ride height. Never inflate beyond 100 PSI (7 BAR). If the system develops an air leak, use a soapy water solution to check all air line connections and the inflation valve core before deflating and removing the air spring. After 500 miles (800 km), recheck all bolts for proper torque.
Use a spray bottle with a soapy water solution to check all air line connections and the inflation valve core. Apply the solution to all connections and look for bubbles, which indicate a leak. All leaks must be eliminated before the vehicle is road-tested.
Yes, the MN-1197 kit (57343 or 93343) is designed for the Ford F-350 Commercial Chassis. Before purchasing, verify your vehicle has at least 7.5 inches of clearance between the frame and tire when fully inflated, and that the body above the axle is at least 3.75 inches high.
Essential tools include: 3/8 inch torque wrench, heavy duty drill with 3/8 inch and 5/16 inch bits, hacksaw or grinder with cut-off wheel, C-clamp or welding clamp, hoist and axle lift or floor jack, safety stands, tire chocks, air compressor, and standard/metric wrenches and sockets.
Three steps: (1) Trim or relocate any ground strap bolt protruding from the frame behind the right axle. (2) Remove the heat shield and strap from the right shock. (3) Space inward the wiring/fuel/line holder on the left frame rail using the included spacer shim.
Yes. You must drill four 3/8 inch holes in the frame for the upper bracket mounting, and one or more 5/16 inch holes for the Schrader valves. Before drilling the frame, check the back side for brake lines, gas lines and wiring harness.
Lower bracket U-bolt attachment: 16 lb.-ft. (22 Nm). Upper bracket frame mounting: 44 lb.-ft. (60 Nm). Air spring mounting hardware: no more than 20 lb.-ft. (27 Nm). Recheck all bolts after 500 miles.
The maximum air pressure is 100 PSI (7 BAR). Never inflate beyond this pressure. The actual pressure needed depends on your load and vehicle's gross vehicle weight rating (GVWR).
Perform a clearance test at 40-60 PSI (check tire, brakes, frame, shocks and cables for 0.5 inch minimum clearance), a leak test using soapy water, a heat test (6 inch minimum clearance from exhaust), and a fastener test. After 500 miles, recheck all bolts for proper torque.
Check air pressure weekly. Always maintain normal ride height and never inflate beyond 100 PSI (7 BAR). After 500 miles, recheck all bolts for proper torque.
Use a soapy water solution to check all air line connections and the inflation valve core. Apply the solution to all connections and look for bubbles, which indicate a leak. Once you have identified the leak location, deflate and remove the air spring to repair or replace the leaking component. All leaks must be eliminated before the vehicle is road-tested.
