PLEASE READ BEFORE YOU START

TO GUARANTEE A QUALITY INSTALLATION, WE RECOMMEND READING THESE INSTRUCTIONS

THOROUGHLY BEFORE BEGINNING ANY WORK. THESE INSTRUCTIONS ASSUME A CERTAIN

AMOUNT OF MECHANICAL ABILITY AND ARE NOT WRITTEN NOR INTENDED FOR SOMEONE NOT

FAMILIAR WITH AUTO REPAIR.

NOTE: This system uses a no-drill top mount drag link that requires an unmodified OEM steering knuckle. If your vehicle currently has a modified knuckle with sleeve inserted from top/previous generation AEV drag link (see illustration), you must order PN 68216188AA OEM knuckle.

Failure to do so will result in an unsafe installation and potential steering failure.

PASSENGER-SIDE

!

ATTENTION

!

IMPORTANT: IMPROPER NUT TORQUE COULD CAUSE STEERING FAILURE.

Proper clamp load is critical on the no-drill draglink to knuckle interface. The nut MUST be torqued to 120-130 ft-lb using a torque wrench. Drag link should also be inspected and the nut torque checked after 500 miles and at each oil change. Do not install using an impact gun or a “tight enough” mentality.

They must be properly torqued to the specified range using a torque wrench.

NOTE: Installation on a Powerwagon requires the purchase of new Coil Springs,

Mopar PN: 68172091AA (front) and 68091216AA (rear).

NOTE: If installing with the factory front bumper, some trimming of the bumper will be necessary.

NOTE: If running smaller than 20” wheels, 6” or less of backspacing is required.

Factory 18” wheels will not clear top-mount draglink.

This product is covered under the AEV Parts Limited Warranty, a copy of which can be found at aev-conversions.com/warranty.

A. Front Suspension Preparation

NOTE: SAVE ALL HARDWARE UNTIL INSTALLATION IS COMPLETE.

1. Support the vehicle by the frame until the front wheels are off the ground.

2. Remove the front wheels and tires.

3. Remove the drag link.

a. Measure from center of pitman arm tie rod stud to center of passenger side knuckle stud. Record the length for reference when setting new draglink length.

b. Loosen both jam nuts.

c. Remove the drag link at the axle end.

d. Thread adjuster sleeve out until separated from drag link and pitman arm tie rod (fig. 1).

Figure 1 e. Remove jam nut off of the pitman arm tie rod end. This will not be re-used. Jam nut on draglink end can be discarded along with original draglink..

4. Remove the track bar and save the hardware.

5. Remove the sway bar links at the axle end only.

6. Remove the steering damper bolt at the axle. Leave attached at the tie rod.

7. Remove the front brake lines.

a. Clamp off the flexible brake lines (fig. 2).

b. Remove the steel brake lines between the two flexible lines (fig. 3).

11. Disconnect the front drive shaft at the axle end. Make sure to mark both sides of the connection so you can properly align it when you reconnect it . Tie loose end of the drive shaft up so it will not hang down. Failure to follow this step may result in damage to your drive shaft.

12. Support the front axle and remove the shocks.

13. Lower the front axle enough to remove the front coil springs. Check to make sure the brake lines are not catching on anything.

14. Remove the lower coil spring isolators from the axle.

c. Install the supplied M18 X 80 bolt, washer, and locking flange nut on the frame side, passing through from the rear of the vehicle to the front. NOTE: If installed backward the bolt can interfere with the axle during suspension movement.

d. Torque all hardware at this time (fig. 18) EXCEPT: Coil Spring mount hold down bolts and frame-side track bar bolt.

7. Install the brake line/bump stop brackets and the bump stops.

a. Pre-assemble the brake line/bump stop brackets to the bump stops as shown (fig. 21). Only snug bolts at this time, you will need movement to adjust position on vehicle.

Figure 21 b. Place the bump stop/bracket assemblies on the axle and start the bolts into the coil spring mounts. Secure with M10 X 25 bolts and M10 Washers but DO NOT tighten (fig. 22).

NOTE: Due to some variations in axles modification of the driver-side coil bucket MAY be required.

If the coil bucket is making contact with the brake line bracket and not allowing for proper seating, then it is necessary to remove that portion of the coil bucket (fig. 23).

ATTENTION !

IMPORTANT: IMPROPER NUT TORQUE COULD CAUSE STEERING FAILURE.

Proper clamp load is critical on the no-drill draglink to knuckle interface. The nut MUST be torqued to 120-130 ft-lb using a torque wrench. Drag link should also be inspected and the nut torque checked after 500 miles and at each oil change. Do not install using an impact gun or a “tight enough” mentality.

They must be properly torqued to the specified range using a torque wrench.

a. Thread the new adjuster 6 turns (approx, 3/8”) onto the pitman arm tie rod end before starting threads on draglink (fig. 33)

Figure 33 b. Begin threading draglink end into adjuster. Rotate adjuster until length is close to measurement recorded during disassembly (step 3a). In isolated cases, the OEM pitman arm tie rod end may need to be trimmed slightly to allow draglink assembly to be adjusted short enough. If unable to reach length recorded in step 3a, remove adjuster from OEM pitman arm TRE and trim off clocking feature and 1/4” of thread from the end, being careful not to damage the threads(fig. 34).

Clean up the end of the threads, make sure adjuster threads on freely, and then apply paint or anti-rust coating to the trimmed end. Reinstall draglink and adjuster and adjust to length from step 3a.

c. Install new draglink into knuckle. Install tapered insert from bottom side of knuckle and secure with provided nut. Torque nut to 120-130 ft-lb . (fig. 35).

Figure 35 d. Re-check length measurement and adjust as needed. Make sure tie rod end at pitman arm is clocked parallel to pitman arm surface. Not doing so will cause bind and potential damage during steering and suspension movement (fig. 36). Tighten both adjuster clamps to 40 ft-lbs

(fig. 37).
