Stabilizer Link - Rattle/Pop Noises

Group: CHASSIS
Number: 93-50-011
Date: SEPTEMBER 1993
Model: 1992 - 1993 ELANTRA

Subject:
STABILIZER LINK NOISE

PURPOSE

Some 1992-93 Elantras, may exhibit a rattle or popping noise from the front suspension. This bulletin explains the cause and correction of the noise.

CAUSE

The noise may be caused by corrosion in one or more of the stabilizer link ball joints. The ball joints may corrode if their dust boots allow moisture to enter. Moisture in the ball joint produces rust, leading to rattling or popping noises from the front suspension. There are two ball joints on each stabilizer link. Stabilizer links are located on both ends of the stabilizer bar.

CORRECTION

1. Raise the vehicle and visually inspect the dust boots on all stabilizer link ball joints. Replace the stabilizer link if cracks or other damage is found on any of the ball joint dust boots.

2. If the dust boots are not damaged, remove both stabilizer links and check the starting torque of each ball joint. To check the starting torque (the force required to turn the ball joint stud), place the stabilizer link in a vise and use an appropriate torque wrench and deep socket. The standard value for starting torque is 1.7-3.2 N-m (15-28 in.lbs.). If any of the ball joints are not within the standard values for starting torque, replace the stabilizer link.

3. If the dust boots are not damaged and the ball joints are within starting torque specifications, the stabilizer link is functional and should be carefully re-installed on the vehicle. Replace only those links that fail the dust boot inspection and starting torque check.
