In this brief article we are going to discuss the different Nissan Qashqai Suspension problems, what the causes are, and Troubleshooting Tips.
Top 6 most common suspension issues in the Nissan Qashqai?
The most common suspension issues seen in the Nissan Qashqai are:
- Front Strut Top Mount Bearing Failure
- Front Lower Control Arm Failure
- Anti Roll Bar Drop Link Failure
- Anti Roll Bar D-Bush Wear
- Rear Trailing Arm Rust
- Front Shock Absorber Failure
What suspension does the Nissan Qashqai have?
The Front suspension in the Nissan Qashqai is a MacPherson Strut and Lower control Arm with Anti-roll bar. This arrangement is mounted onto the front subframe.
The J11 generation of Nissan Qashqai had a Torsion Beam Trailing Arm Suspension configuration.
The previous generation of Nissan Qashqai, namely the J10 had a 3-link rear suspension set-up with a Trailing Arm, Upper and Lower control arms, Coil Springs and Anti Roll Bar
Front Strut Top Mount Bearing Failure
- Knocking Noise while going over Rough Road Patches
- Bumping/Knocking Noises when trying the lock steering in parking
Troubleshooting Front Strut Top Mount Bearing Failure
- The Top Strut Mount contains a bearing that allows the strut to rotate while steering
- When the Top Strut mount is damaged, the bearing also fails and restricts the strut from rotation during steering. This is what causes the knock and creak noises.
Front Lower Control Arm Failure
- The car seems to be drifting
- Steering seems vague while Lane Changing
- Uneven Tire Wear pattern
- Knocking Noises while going over Rough Patches
- Due to a Tire wear issue, it can be inferred that the alignment of the front suspension is outside of the recommended settings. But this is still a symptom.
- The cause for alignment change points to the Lower control arm Bushings and Ball-joints that may have got worn or damaged
Troubleshooting Front Lower Control Arm Bushing Failure: Lower Control Arm Bushing
- Lower Control Arm bushing wears out over time and cracks due to age
- When inspecting the Lower control arm after removal, it is clear that there are tears and cracks in the rubber portion
Troubleshooting Front Lower Control Arm Bushing Failure: Lower Control Arm Ball-Joint
- The lower control arm ball-joints are also subject to wear and tear.
- The deterioration is usually initiated as a crack or rupture in the rubber boot around the ball-joint
- This leads to loss of lubrication and finally to complete wear out
- The wear out causes play or movement accompanied by knocking noise. The play in the ball-joint is one of the reasons for the vehicle steering feeling value
- The best course of action would be to replace the whole Lower control arm since it comes with 2 new bushings and 1 new ball-joint all pre-assembled
Anti Roll Bar Drop Link Failure
- Clunking Noise while normal driving
- Noise gets worse when going over a rough patch
Troubleshooting Anti Roll Bar Drop Link Failure
- Clunking noises, in most passenger cars, almost always point to the Anti-roll bar linkages
- The noise is due to the play in the joints of the Anti Roll BAr Drop links.
- One good way to diagnose this problem is to hold the Anti-roll Bar and Push and Pull it hard.
- If you see the ball-joint separating and moving along with a knocking noise, then you have found the root cause for Clunking Noise
- Once you remove the Drop Link, you can check the ball-joints by hand the see if they move with play
Anti Roll Bar D-Bush Failure / Dryness
- Squeak Noises while driving
- Noise is more apparent when going over a rough patch
Troubleshooting Anti Roll Bar D-BushFailure
- Squeaks and Creaks generally relate to metallic Spring elements within the suspension, namely, the Coil Spring and the Anti-Roll Bar
- If the noise is more apparent on a rough road one could be more suspicious of the Anti Roll Bar
- In order to confirm this, you can try rotation the Anti-roll Bar by hand after removing the Drop-link ball joint.
- If you hear the Creaking Noise, then it’s confirmed that the Anti-roll bar was indeed the issue.
- When you rotate the Anti Roll Bar, it does so on the support of a D-Bush Rubber (or Polymer) Bearing that connects the the Anti-roll bar to the Chassis frame
- The Anti roll bar metal rod rotates within this bush and rubs itself on the inner surface of the bushing. This causes considerable friction or wear.
- If this D-Bush is of harder Polymer-based material then it requires lubrication. There are Anti-roll bar mounting grease products available in the market which you could use.
- Or refer to the manufacturer’s Service Instructions to see if there is a particular product recommended
Rear Trailing Arm Rust
- Creaking Noises from the Rear going over bumps
- As seen in the Qashqai J10 generation which had a 3-Link Rear suspension set-up.
Troubleshooting Rear Trailing Arm Rust
- Creaking noises generally originate from the Metallic elements within the suspension such as springs and anti-roll bars
- In some cases, suspension arms could also be an issue either due to Fracture, bending or even Corrosion.
- It would always be advised to inspect all the suspension components and check for issues.
- Rusted Springs and Rusted Control arms tend to creak, indicating imminent failure
Front Shock Absorber Failure
- Rattling Noise going over any rough patches
- Front end bouncier than normal
- Changes in handling behaviour; Vehicle not feeling stable at high speed cornering
Troubleshooting Front Shock Absorber Failure
- The Bouncy Ride symptom points to the Shock Absorber as a probable cause.
- If your vehicle has crossed 50K miles, then it could be due for a shock replacement. Due to long-term internal wear, the shock starts becoming ineffective over time.
- If the front strut shock has started leaking oil due to a failed oil-seal, then it means that the shock will no longer be effective.
- One good way to tell if your shock has failed or not is to do a “Bounce Test”. Put all your weight on one of the front corners of the vehicle pushing it downwards. Keep oscillating the corner till you feel that it has reached its maximum height. Once you take your hands off the corner, observe how it settles. If it takes more than 2 oscillations to settle, that means the damper has failed.
