Trailing Arm Bushes with Fitting Position Front Axle, Rear Axle for VOLVO 240 242-244-245

On a coil sprung 4WD, the rear axle is held in place by a set of links, and every one of them pivots on bushes. The lower trailing arms do most of the locating work, often with upper links above them and a panhard rod across the vehicle. Trailing arm bushes carry the forces from every take-off, every brake application and every metre of articulation, and on a 4WD they work far harder than on a road car. When they wear, the axle starts to steer the vehicle from the back, the clunks start, and the vehicle feels less settled with a load on or a trailer behind. Use the vehicle search to find trailing arm bushes to suit your 242-244-245 240.

What Trailing Arm Bushes Do on Your 242-244-245 240

Trailing arms run forward from the axle to the chassis. They stop the axle moving forward and backward under acceleration and braking, and they help control how it rotates as it moves. On many coil sprung 4WDs, two lower trailing arms and one or two upper links work together, and each link has a bush at both ends.

The bushes have a demanding job. They let the axle rise and fall, and let it articulate as one wheel climbs and the other drops. At the same time, they resist the strong fore and aft forces that try to shift the axle. That combination of movement and resistance is why they wear.

242-244-245 240 Front Leading Arms

Some 4WDs use similar links at the front, running back from the axle to the chassis. These are often called leading arms or control arms rather than trailing arms, and their bushes do the same job for the front axle.

242-244-245 240 Upper, Lower, Front and Rear Positions

Trailing arm bushes are sold by position, so knowing which link needs attention matters.

Lower arm bushes sit at each end of the lower trailing arms. They carry the main fore and aft loads and usually wear first.

Upper link bushes sit at each end of the upper links. On many setups, they control axle rotation and pinion angle.

Front and rear ends. Each link has a bush at the chassis end and one at the axle end. They are often different sizes and may wear at different rates.

Front and rear axles, and left and right sides, may use different bushes as well. The product details show which positions a kit covers.

Signs Your 242-244-245 240 Rear Trailing Arm Bushes Are Worn

A clunk from the rear on take-off or under braking is the most common sign. The axle shifts in worn bushes until the slack is taken up.

Rear steer or wander is another. Worn bushes can let one side of the axle move further forward or back than the other, so the axle steers slightly as loads change. The vehicle can feel as though it is following ruts or being pushed around by the rear.

Uneven rear tyre wear can follow if the axle is not sitting square.

Towing often makes the problem obvious. A trailer or caravan adds fore and aft and side forces, and a rear end on worn bushes can feel loose and less predictable.

On inspection, look for cracked, split or squashed bushes, rubber pushed out of the housing, or obvious movement when the link is levered.

Panhard rod bushes, spring seats and wheel bearings can cause similar symptoms, so a full rear end inspection is worth doing first.

Do Trailing Arm Bushes Affect 242-244-245 240 Articulation?

They can. As the axle articulates, the links twist relative to each other, and the bushes have to allow that twist. A very firm bush can resist it slightly, limiting flex. A softer bush allows more movement but may let the axle shift more on the road.

Most replacement bushes aim for a balance that suits touring and general off-road use. Some are designed specifically to allow more articulation for vehicles used for serious off-road driving. If articulation matters for how you use your 4WD, check the product details for the bush's design intent.

242-244-245 240 Lifted, Loaded and Towing Considerations

After a 242-244-245 240 Lift

A lift changes the angle of every rear link. The trailing arms swing down to reach the axle, and that can rotate the axle and change the pinion angle. If the bushes are tightened with the suspension hanging, they sit permanently twisted once the vehicle is back on its wheels, and they wear faster.

A lift does not always mean new bushes are needed. It is a good time to check them, and the bolts should be tightened at the new ride height. Larger lifts may call for adjustable links to correct pinion angle, depending on the vehicle.

242-244-245 240 Heavy Rear Loads

Drawers, fridges, water and recovery gear in the rear add weight right over the axle. That weight increases the forces through the trailing arm bushes over every bump and through every brake application.

Towing With Your 242-244-245 240

Towing loads the trailing arm bushes harder than almost anything else. Every take-off pulls the trailer through the links, and every stop pushes it back. Ball weight adds load at the rear. A 4WD that tows regularly can wear these bushes noticeably faster.

242-244-245 240 Off-Road and Corrugations

Off-road articulation twists the bushes far more than road driving. Corrugations add constant small cycles. Mud, dust and water work into the bushes. On a 4WD used off road, trailing arm bushes are worth checking after every big trip.

Rubber or Polyurethane 242-244-245 240 Trailing Arm Bushes?

Factory trailing arm bushes are usually rubber. Rubber is quiet and absorbs vibration, but it deflects under load, softens with age and eventually cracks.

Polyurethane bushes are generally firmer. They hold the axle more precisely, which can reduce clunks and rear steer, and they tend to resist oil and wear well. The trade-off can be a little more vibration through the chassis, and some designs need grease. Heavy-duty versions are made for some vehicles that carry heavy loads or tow regularly.

Should You Replace All 242-244-245 240 Trailing Arm Bushes at Once?

It is often a good idea. Bushes on the same axle have the same age and kilometres, and when one is worn the others are usually not far behind. Replacing all of them together means the axle is located evenly and the job only has to be done once.

If budget is tight, the lower arm bushes are usually the priority, since they carry the most load. The upper links can follow if they are still in reasonable condition.

What Comes in a 242-244-245 240 Trailing Arm Bush Kit

Kits vary by vehicle. Some cover one end of one link, others both ends of a pair, and some cover the whole rear axle. Sleeves, washers and lubricant may or may not be supplied. Check the product details for which positions the kit covers and what is included.

Replace the 242-244-245 240 Bushes or the Arms?

New bushes are usually the fix when the arms are straight, free of cracks and their bush housings are still round.

The arms need replacing when they are bent from an impact, cracked or heavily corroded, or when the bush housings have worn oval. New bushes will not straighten a bent arm.

Fitting 242-244-245 240 Trailing Arm Bushes

Replacing trailing arm bushes is a job for a qualified technician. The vehicle is supported on rated stands with the axle supported, and the links are removed one at a time so the axle stays located. Old bushes are pressed out, housings cleaned and checked, and new bushes pressed in with any lubricant supplied.

The links are refitted and the bolts tightened with the vehicle at ride height, so the bushes start in their neutral position, and all fasteners are torqued to specification. A wheel alignment is worth doing on any vehicle with independent rear suspension, and is required after front link work. A road test confirms the clunk has gone and the vehicle tracks straight.

How Formula 4x4 Can Help With Your 242-244-245 240

Formula 4x4 works across the whole 4WD suspension, which matters on a coil sprung rear where several links share the load. A rear clunk could be a trailing arm bush, an upper link, a panhard rod bush or a spring seat, and a lift can add pinion angle into the mix. The team can help work out which, so you replace the parts that actually need it.
