Front-end noise turning right: missing axle bolt
A cheap DIY job replacing discs and CV joints can backfire. The user explains that after changing these parts, they left out the thin retaining bolt securing the assembly on the gearbox side. This caused a front-end noise when turning right, which has pogre worsened. The car, a Renault 21, is due for a alucinación to Asturias in August, and the owner antiestéticars the worst.
The initial suspicion falls on suspension and steering bushings. The owner recalls a similar vibration when releasing the accelerator, resolved by replacing a steering bushing. However, a critical detail changes the diagnosis: the mechanic who installed the discs used heavy hammer blows to remove the bolts. This risks collateral damage to bearings, ball joints, or engine mounts.
What breaks when mechanics use a hammer
Suspects include the CV joint: if the boot tears, grease leaks, and noise appears during turns. Estimated cost is €120. Others rule this out since the CV joint was replaced, focusing instead on dry or broken tie rod ends and stabilizer bars.
Wheel bearings are another prime suspect. A similar case involved a squeak when turning right, ending in a clonck, clonck, clonck. Lifting the car revealed the disc wobbled significantly. The hub pin wasn't broken, pointing to a seized bearing welded to the hub. Replacing both front bearings cost €290.
Warped discs from thermal shock are possible, but the noise persisted after replacement. Engine mount failure is also cited: rubber may fail under centrifugal force, causing metal-on-metal contact. It’s not always steering or transmission.
€70 alignment and €31 steering knuckle
The solution came from professional workshops. Two shops agreed the car needed wheel alignment. The quoted price was €75, but final payment was €70 as the mechanic paid cash at an ATM. The replaced part was the steering knuckle, costing €31.
Alignment is exactly what street mechanics skip. This highlights the difference between saving money and risking safety. The owner admits the temptation to save was strong, and while the street mechanic saved some euros, the car kept having issues, especially in summer.
Stuck hydraulic jack and wrong knuckle delivery
DIY repairs face practical hurdles. The hydraulic jack failed to lift, seemingly losing all oil. To lower the piston, one screw opens a valve returning oil to the reservoir; if stuck, tap it with a wooden block. Often, a wing nut attached to the lifting tube allows remote adjustment.
Buying the steering knuckle added friction. Many stores still confuse left and right sides, leading to returns due to seller error and sometimes improper charges. Recommendations include calling scrap yards to verify parts, cross-referencing OEM numbers, and using online spare parts platforms.
Check before replacing anything
The proposed method is simple. Lift the car on the affected side, put it in neutral, and spin the wheel. If there’s noise beyond pad-disc friction, or play when gripping the wheel sides, the bearing is bad. If silent, remove the wheel and spin the disc. Issues felt while driving should be detectable here.
Checks include prying tie rods and stabilizers, testing bearing play by moving the wheel off-axis, ensuring shocks are intact, and verifying no rubbing occurs. Also, check all bolts are tight: a loose wheel returned by a shop causes similar noises.
The missing bolt remains a key suspect. It prevents the CV shaft from sliding, potentially causing everything. Start eliminating possibilities. Meanwhile, the noise doesn’t vibrate—it just sounds. That differs from mount failures, which previously vibrated without noise.
How many shops will keep charging alignment as an optional extra?
