We carry parts for it Not stocked yet Hover or tap any part.
From 2015 the car has electric power steering: the rack ahead of the front axle carries an assist motor behind it, so there is no power steering pump or fluid. The front is a short and long arm design with a coilover strut on each side, a forged upper arm around the strut and two separate lower arms: a straight lateral arm that carries the strut and a tension strut that runs forward to a bushing on the front cradle. The rear has five links per side on a subframe: a wide spring link with the coil, a toe link behind it, a lower forward arm and two upper arms, with a separate shock and halfshafts from the differential. The drawing shows the rear wheel drive car; all wheel drive cars have a different front lower arm and a front differential.
We carry replacement parts for 42 of the 52 components on this diagram, 159 parts in all. See every part for the 2015 Chrysler 300.

Front Suspension
1 Front Strut (Coilover Shock) (driver and passenger side)
The front shock is a coilover strut. Its forked bottom bolts to the middle of the lower lateral arm, its body passes up through the upper control arm, and its top bolts under the shock tower. It also carries the sway bar link on a tab.
Signs of wear: Bouncing after bumps, nose dive under braking, fluid on the body, or a knock from the top of the strut.
Tip: Struts are sold bare or as a complete assembly with the spring and mount fitted. The complete assembly needs no spring compressor.
See all Front Shock Absorber parts for the 2015 Chrysler 300
2 Front Coil Spring (driver and passenger side)
The front coil spring sits on a seat high on the strut body, above the upper control arm, and pushes up against the strut mount.
Signs of wear: A front corner sitting lower than the other, a broken coil end, or a clunk when turning at a stop.
Tip: Replace springs in pairs. Lowering spring sets for these cars come as front and rear pairs.
We don't carry a front coil spring for the 2015 Chrysler 300 yet. Ask us about this part and we will try to source it.
3 Front Coil Spring Seat (driver and passenger side)
Rubber seats sit under and over the front coil, on the strut body and under the strut mount, so the spring does not rattle against metal.
Signs of wear: Squeaks or creaks over bumps from the front, or a spring that has worn a groove into its seat.
Tip: Fit new seats whenever the strut or spring is apart.
See all Front Coil Spring Isolator Pads parts for the 2015 Chrysler 300
4 Front Strut Mount (driver and passenger side)
The strut mount is the rubber block at the top of the strut. Three studs bolt it under the shock tower.
Signs of wear: A clunk from the top of the strut over bumps, or a knock when the front unloads.
Tip: The mount is often replaced with the strut, since the strut has to come out either way.
5 Front Strut Bellows and Bump Stop (driver and passenger side)
A rubber bellows covers the strut rod to keep grit off its seal, and the bump stop inside it cushions the strut at full compression. The coil hides it in the assembled view.
Signs of wear: A torn boot, a scored strut rod, or a hard bang over big bumps.
Tip: Fit a new boot and bump stop whenever the strut is replaced.
See all Front Shock Bellows Boot Kit parts for the 2015 Chrysler 300
6 Front Upper Control Arm (driver and passenger side)
A forged A-shaped arm. Its two inner bushings bolt to the body beside the shock tower, the strut passes through the middle of the A, and its ball joint carries the top of the knuckle.
Signs of wear: Clunks over bumps, uneven tire wear, or play at the upper ball joint.
Tip: Rear wheel drive and all wheel drive cars use different upper arms. Adjustable arms are sold for camber and caster correction.
7 Front Upper Control Arm Bushing (driver and passenger side)
Each upper arm pivots on two rubber bushings, front and rear, on bolts that run front to back.
Signs of wear: A clunk when braking or turning, or rubber that is cracked or pushed out of the arm.
Tip: Upper arms are usually replaced as a unit with new bushings and ball joint fitted.
See all Front Control Arm Bushings parts for the 2015 Chrysler 300
8 Front Lower Control Arm (Lateral Arm) (driver and passenger side)
A straight forged arm running from the cradle out to the bottom of the knuckle, behind the tension strut. It pivots on a bushing at the cradle, carries the strut on its middle bushing, and bolts to the ball joint stud at its outer end. All wheel drive cars use a one piece lower control arm with two inner bushings and a front differential instead; parts marked AWD fit those cars.
Signs of wear: Clunks over bumps, a wandering feel, or cracked bushings in either eye.
Tip: On rear wheel drive cars the ball joint is a separate part pressed into the knuckle.
9 Front Lower Control Arm Bushing (driver and passenger side)
The lateral arm has two rubber bushings: one at the cradle and one in the middle, which the strut fork bolts through.
Signs of wear: A clunk over bumps or when braking, or a strut that rocks on the arm.
Tip: Bushings for all wheel drive arms are a different part from the rear wheel drive arm.
See all Front Control Arm Bushings parts for the 2015 Chrysler 300
10 Front Lower Ball Joint (driver and passenger side)
The lower ball joint is pressed into the bottom of the knuckle. Its stud points down through the end of the lateral arm, held by a nut. Some replacement joints are offset to adjust camber.
Signs of wear: Clunks over bumps, a loose front end, or play when the wheel is rocked top to bottom.
Tip: The joint is pressed out of the knuckle and a new one pressed in. It fits rear wheel drive cars.
See all Front Lower Ball Joint parts for the 2015 Chrysler 300
11 Front Tension Strut (Lower Forward Arm) (driver and passenger side)
A long forged rod with a ball stud at the knuckle and a large rubber bushing at the front of the cradle. It holds the bottom of the wheel from moving back and forth under braking.
Signs of wear: A clunk or shimmy when braking, steering that pulls under braking, or a torn front bushing.
Tip: Left and right are different parts. The arm comes with its ball joint and bushing fitted.
12 Front Tension Strut Bushing (driver and passenger side)
The large rubber bushing at the front end of the tension strut, mounted upright in the front of the cradle.
Signs of wear: A clunk when braking or pulling away, or a bushing that is split or leaking.
Tip: Offset polyurethane bushings are sold to add caster.
13 Front Lower Arm Cam Bolt (driver and passenger side)
A cam bolt with eccentric washers replaces the bolt through the lateral arm inner bushing, so camber and caster can be set at alignment.
Signs of wear: Tire wear on the inner or outer edge that a normal alignment cannot correct.
Tip: An alignment is needed after fitting it.
See all Front End Alignment Kit parts for the 2015 Chrysler 300
14 Front Steering Knuckle (driver and passenger side)
A tall knuckle that reaches up inside the wheel to the upper ball joint. It carries the hub and caliper, takes the lower ball joint and the tension strut at the bottom, and has the steering arm at the front.
Signs of wear: Knuckles rarely wear out. A bent knuckle shows as a pull that an alignment will not fix.
Tip: Not usually replaced unless damaged.
We don't carry a front steering knuckle for the 2015 Chrysler 300 yet. Ask us about this part and we will try to source it.
15 Front Sway Bar
The front sway bar runs across behind the cradle. Two bushings hold it to brackets on the cradle, and its ends come forward to links up to the struts.
Signs of wear: More body roll than normal in corners. The bar itself rarely fails.
Tip: Thicker aftermarket bars are sold to reduce body roll.
16 Front Sway Bar Bushing
Two rubber bushings clamp the bar to brackets on the cradle, under heat guard covers.
Signs of wear: A clunk or squeak over bumps and when turning.
Tip: Bushings are sized to the bar. Most 2015 and later rear wheel drive cars have a 32 mm (1.25 inch) front bar.
See all Front Sway Bar Bushings parts for the 2015 Chrysler 300
17 Front Sway Bar Link (driver and passenger side)
A link with a ball stud at each end, from the end of the bar up to a tab on the strut body.
Signs of wear: A knock or rattle from the front over small bumps.
Tip: Rear wheel drive cars use left and right links; all wheel drive cars use a different link.

Questions about the 2015 Chrysler 300 suspension
What changed on the 300 in 2015?
The 2015 facelift brought an electric steering rack with new inner tie rods, a thicker front sway bar on most cars, an aluminum rear upper rearward arm and a new rear hub. The control arms, struts and other links are the same parts as on the 2011 to 2014 cars.
What are the most common suspension wear items on a 2015 Chrysler 300?
The front tension struts and their large front bushings, the lower ball joints, the upper control arms and the front sway bar links are the parts most often replaced, followed by tie rod ends. A clunk or shimmy when braking often points to a worn tension strut bushing.
Why are there two front lower control arms?
On rear wheel drive cars the bottom of the knuckle is held by two separate arms. The lateral arm runs straight in to the cradle and carries the strut, and the tension strut runs forward to a bushing at the front of the cradle. Each has its own ball joint at the knuckle.
Is the all wheel drive 300 different underneath?
Yes, at the front. All wheel drive cars have a front differential with CV axles, a one piece lower control arm, and different upper arms, tie rods, sway bar links and hubs. The rear suspension is the same. Check the drive type on each part before ordering.
Do I need an alignment after replacing suspension parts?
Yes, after replacing tie rods, control arms, the tension strut or any rear link. Front camber and caster can be set with a cam bolt kit or an adjustable ball joint, and rear camber and toe with offset bushings.
