Wrangler TJ Front Lower Control Arms – Heavy Duty Adjustable Pair for Jeep Wrangler TJ 1997 1998 1999 2000 2002, 7898954

Wrangler TJ Front Lower Control Arms – Heavy Duty Adjustable Pair

These Wrangler TJ front lower control arms are a pair of adjustable steel arms with polyurethane bushings, built for Jeeps that have been lifted and need a longer or shorter lower link than the factory one. The length adjusts from 385 to 470 mm, and the supplier says they are good for lifts up to four inches. The supplier lists them for the Jeep Wrangler TJ, the Cherokee XJ and the Grand Cherokee ZJ. Easy Life Markets sells the two arms with four bolt sleeves.

The front axle on these Jeeps is located by links running back to the frame, and the lower pair does most of the work of holding the axle in position front to back. Lift the Jeep and the fixed-length factory arms pull the axle backwards and tilt it, which changes the caster angle and the way the steering returns to centre. An adjustable arm lets you set the length to suit the lift, so the axle sits where it should under the wheel arch. Each end pivots on a bushing, and on this pair those are polyurethane.

Package Contents

• 2 x front lower adjustable control arms
• 4 x metal sleeves, for use across the different vehicle models

One of the product photos also shows a printed installation leaflet next to the arms. The supplier's written contents list does not mention it, so do not count on one being in the box. Mounting bolts are not listed.

About the Sleeves and Bolt Sizes

This is the detail to read twice. The supplier states that the arms come with metal sleeves in two inner diameters, 14 mm and 16.5 mm, to suit M12, M14 and M16 bolts, and asks buyers to choose carefully. The sleeve sits inside the bushing and the mounting bolt passes through it. Use the sleeve that matches the bolt at each mount on your vehicle. A sleeve that is too large lets the bolt move in the joint, which wears the bracket and makes the arm knock. Measure your existing bolts before you start, and do not assume both ends of the arm use the same size.

Compatibility

The supplier lists the pair for:

• Jeep Wrangler TJ, 1997–2006
• Jeep Cherokee XJ, 1986–2001
• Jeep Grand Cherokee ZJ, 1993–1998

The supplier's title names the Wrangler TJ for 1997, 1998, 1999, 2000 and 2002, while the application list gives the wider 1997–2006 range. We show both because we cannot say which is more precise. To check your own Jeep:

1. Measure your current front lower arms from bolt centre to bolt centre. The length you need must fall between 385 and 470 mm, with some thread left in reserve.
2. Measure the mounting bolts at the axle and the frame and confirm they are M12, M14 or M16.
3. Measure the bracket width at both mounts and compare it with the bushing ends in the photos.
4. Know your lift height. The supplier rates these arms for lifts up to four inches.
5. Send us the details. If you want a second opinion, contact us with your VIN, model and lift height.

Signs the Front Lower Arms Need Replacing

• A clunk from the front under braking or when moving off
• Steering that wanders, or a shimmy through the wheel after hitting a bump
• Poor steering return to centre after the Jeep was lifted
• Front tyres sitting too far back in the wheel arch
• Factory bushings that are cracked, split or have come away from the arm
• Arms that are bent or dented from off-road use

Installation and Setup

• The supplier recommends professional installation.
• Set both new arms to exactly the same length before fitting, starting from the length of the arms you are removing or from the figure your lift kit maker specifies.
• Support the frame on stands rated for the vehicle and change one arm at a time, so the axle cannot roll.
• Fit the correct sleeve at each end, then insert the bolts without forcing them.
• Lock the adjuster once the length is set, with enough thread engaged to be safe.
• Tighten the pivot bolts with the Jeep's weight on its wheels and to the service manual torque.
• Have the caster and the rest of the alignment checked afterwards, and recheck the adjuster after the first off-road outing.

Control arms are safety-critical, and a mistake here affects steering and braking. If you are not experienced with suspension work, have a qualified mechanic do the job.

Looking After Polyurethane Bushings

The supplier says the poly bushings reduce squeaks and vibration and help prevent uneven tyre wear. Polyurethane lasts well but likes to be kept clean. Hose mud out of the joints after off-road use and check the pivot bolts for tightness now and then. If a squeak develops, a suitable polyurethane-safe grease on the sleeve usually cures it.

Who This Pair Is For

It is for owners of lifted TJ, XJ and ZJ Jeeps who need to correct axle position and caster, for people replacing bent or worn factory arms with something adjustable, and for workshops that fit lift kits. On a Jeep at standard height that drives well, fixed arms do the same job.

Common Questions

Are these arms for the front or the rear? The front, lower position. The supplier's contents list is two front lower adjustable arms.

Are they genuine Jeep or Mopar parts? No. They are unbranded aftermarket arms and are not made by the vehicle maker.

Why are there four sleeves? So the arms can be matched to the different bolt sizes used across the listed models. Pick the size that fits your bolts.
